  • Publication number: 20080024981
    Abstract: An electronic component generates heat in an electronic apparatus. The heat of the electronic component is transferred to a thermal conductive plate of a heat receiver in a liquid cooling unit. The heat is transferred to coolant from the thermal conductive plate. The temperature of the coolant rises. The heat exchanger absorbs heat of the coolant. The coolant gets cooled. The heat of the electronic component is also transferred to the printed wiring board. The heat spreads over the printed wiring board through a wiring pattern in the printed wiring board. Since the tank or/and pump is placed at a position outside the printed wiring board, the heat cannot be transferred to the tank or/and the pump. This results in prevention of rise in the temperature of the coolant in the tank or/and the pump. The efficiency of heat radiation can thus be enhanced.

  • Publication number: 20080024987
    Abstract: A heat exchanger allows establishment of a flat space between first and second plates. The heat exchanger is inserted in a closed circulating loop for coolant. The flat space is allowed to have a cross-section larger than that of a cylindrical duct of the closed circulating loop. The flat space serves as a flow passage. An increased cross-section enables a reduction in the flow speed of the coolant. The coolant is allowed to slowly flow through the flat space. The coolant thus contacts with the first and second plates for a longer time. The heat of the coolant is sufficiently transferred to the first and second plates. The efficiency of heat radiation is enhanced.

  • Publication number: 20080024978
    Abstract: An electronic apparatus includes an enclosure enclosing a liquid cooling unit. The liquid cooling unit includes a heat receiver received on an electronic component. Heat of the electronic component is transferred to the heat receiver. The heat of the heat receiver is transferred to the coolant flowing through the flow passage of the heat receiver. The electronic component gets cooled. The coolant flows into a tank in the liquid cooling unit. The tank stores the coolant and air. The air inlet is formed in the enclosure. Fresh air is introduced into the enclosure through the air inlet. Since the tank is opposed to the air inlet, the tank is exposed to the fresh air. The heat of the coolant in the tank is thus radiated into the air. The coolant gets cooled in an efficient manner. The efficiency of heat radiation is enhanced in this manner.

  • Publication number: 20080024988
    Abstract: A heat receiver includes a casing defining a flow passage on a thermal conductive plate. The thermal conductive plate is received on an electronic component. The thermal conductive plate serves to transfer heat to coolant in the flow passage. At least two inflow nozzles extend into the casing to have discharge openings opposed to the upstream end of the flow passage. The coolant flows into the flow passage through the inflow nozzles. At least two streams of the coolant are thus generated in the flow passage. The streams widely expand or spread in the flow passage. The coolant flows through the flow passage without stagnating. The coolant can thus absorb the heat of the thermal conductive plate in an efficient manner. This results in an efficient heat absorption of the heat receiver.

  • Publication number: 20080023178
    Abstract: A heat exchanger allows establishment of first and second flat spaces, namely parallel flat spaces along a reference. The heat exchanger is inserted in a closed circulating loop for coolant. The first and second flat spaces have a cross-section larger than that of a cylindrical duct of the closed circulating loop. These flat spaces serve as a flow passage for the coolant. An increased cross-section enables a reduction in the flow speed of the coolant. The coolant is allowed to slowly flow through the first and second flat spaces. The coolant thus contacts with the first and second plates and the third and fourth plates for a longer time. The heat of the coolant is sufficiently transferred to the first and second plates and the third and fourth plates. The efficiency of heat radiation is enhanced.

  • Publication number: 20080024989
    Abstract: A heat receiver includes a casing defining a flow passage on a thermal conductive plate. The thermal conductive plate is received on an electronic component. An outflow nozzle has an inflow opening at the downstream end of the flow passage at a position outside the thermal conductive plate. Since the thermal conductive plate is received on the electronic component, the outflow nozzle is connected to the flow passage at a position outside the electronic component. This results in avoidance of increase in the thickness of the casing as compared with the case where the outflow nozzle directly extends into the flow passage on the thermal conductive plate.

  • Publication number: 20080024980
    Abstract: A liquid cooling unit includes components such as first and second heat receivers, a heat exchanger, a tank and a pump in an electronic apparatus. The electronic apparatus includes a first enclosure and a second enclosure coupled to the second enclosure for relative movement. The liquid cooling unit is enclosed in the first enclosure. No component of the liquid cooling unit is enclosed in the second enclosure. The liquid cooling unit is thus incorporated in the first enclosure in a facilitated manner. This results in a reduced production cost. The liquid cooling unit can also be removed from the first enclosure in a facilitated manner.

  • Patent number: 7298616
    Abstract: A fan housing of a fan unit includes a housing wall standing from the surface of a printed circuit board. The printed circuit board serves to establish the fan housing in cooperation with the housing wall. The fan housing further includes a ceiling wall connected to the housing wall. The ceiling wall extends along a datum plane parallel to the surface of the printed circuit board. A high speed airflow can be generated within the fan housing. The airflow promotes the heat radiation from the printed circuit board. An electrically conductive wiring pattern extending over the surface of the printed circuit board may further promote the heat radiation from the printed circuit board.

  • Patent number: 7248473
    Abstract: An intake opening is defined in a printed circuit board inside a fan cover mounted on the printed circuit board. The intake opening has a particular extent inside the fan cover. This intake opening contributes to improvement in the cooling efficiency of a fan as compared with a conventional intake opening. Moreover, the intake opening allows a sufficient space to remain on the front and back surfaces of the printed circuit board inside the fan cover. Electronic components and/or wiring patterns may be disposed in the space. This contributes to disposition of electronic components and/or wiring patterns at a higher density on the printed circuit board.

  • Publication number: 20070131383
    Abstract: A fan is enclosed in the enclosure of an electronic apparatus. The fan discharges air out of a ventilation opening of the fan itself. Heat radiating fins are located in an air passage extending from the ventilation opening. A dust catcher is removably mounted in an opening of the enclosure from the outside of the enclosure. The dust catcher is located in the air passage between the heat radiating fins and the ventilation opening. The dust catcher serves to catch the dust in the air passage. The dust catcher is removed from the enclosure along with the dust. The dust is thus reliably cleared from the air passage. The dust catcher can then be cleaned. The cleaned dust catcher can again be set in the opening of the enclosure. Airflow of a sufficient amount is in this manner always kept in the air passage.

  • Patent number: 7108563
    Abstract: A LAN connector is connected with a LAN cable connector inserted thereinto. The LAN connector comprises a flexible portion formed outside a modem-cable-connector occupied space within a housing having a size accommodating the LAN cable connector being inserted thereinto, and a stopper portion formed within the modem-cable-connector occupied space. The stopper portion is displaceable together with the flexible portion. When the modem cable connector is inserted into the housing, the flexible portion is not pushed and bent by the modem cable connector, and the stopper portion stops the modem cable connector. When the LAN cable connector is inserted into the housing, the flexible portion is pushed and bent by the LAN cable connector so as to cause the stopper portion to be withdrawn out of the modem-cable-connector occupied space.
