  • Publication number: 20070229292
    Abstract: An abnormal warning apparatus and detecting device that can be applied widely in a fluid circulating system is provided. The abnormal warning apparatus essentially includes a brightness tuning device, a light detecting unit, an analysis circuit, a light emitter, and an alarm. The ray of the light emitter penetrates through the tube having the brightness tuning device and enters the light detecting unit on the other side. After that, the various voltages transformed from the received ray with strong or week brightness or no light received are entered into the analysis circuit, then the voltages are determined to be normal or abnormal by comparing them with a standard voltage. The alarm goes off to warn with sound or light based on an output of abnormal voltage if the flow stops or becomes insufficient.

  • Patent number: 7249625
    Abstract: A heat dissipation system includes a housing, a circulator and a cooler. The housing has at least one surface made of heat-conductive metal to contact with a heat source. The housing includes a recess with a passage formed on the bottom to contain cooling liquid and an inlet and an outlet connected to the recess. Two pipes are provided to connected between the inlet and the outlet and the cooler, respectively. The circulator is installed in the recess to circulate the flowing of the cooling liquid. As such, heat generated from the heat source is directly conducted to the housing and takes away by the cooling liquid circulated by the circulator to the cooler.

  • Publication number: 20060185378
    Abstract: A liquid-cooling heat dissipation assembly includes a liquid cooling array module with an upper cover and a lower cover on top and bottom sides of the liquid cooling array module, respectively, a liquid driving module assembled to the upper cover of the liquid cooling array module, a cooling plate module assembled with the lower cover of the liquid cooling array module, a liquid passageway defined through the liquid cooling array module and the cooling plate module. The liquid cooling array module, the liquid driving module and the cooling plate module are integrated into assembly and a through runner keeps the cooling liquid to flow continuously. The heat exchange cycle can be speeded up and the heat dissipation efficiency can be enhanced.

  • Publication number: 20060185830
    Abstract: A cooling plate module includes a cooling plate and a liquid driving module. The liquid driving module includes an accommodation chamber and a liquid driving unit used to driving cooling liquid. The liquid driving module includes a liquid inlet communicated to the accommodation chamber and a first liquid outlet is communicated to the bottom of the accommodation chamber. A cap encloses the first liquid outlet and a second liquid outlet is defined on the cap. The cooling plate is assembled with the cap to define a closed space therein and the first liquid outlet is corresponding to the heat-dissipating plates. Therefore, there is no duct connecting between the cooling plate and the liquid driving module, the stagnant problem caused by pressure difference can be prevented and the cool liquid can directly flush the heat-dissipating plates for enhancing heat dissipation efficiency.

  • Publication number: 20060185829
    Abstract: A liquid-cooling heat dissipation apparatus includes a casing, a first compartment defined in the casing for assembling a liquid driving unit, a cooling plate module on bottom of the casing, a second compartment defined between an inner space of the casing and the cooling plate module and containing a cooling liquid therein. At least one liquid inlet and liquid outlet are defined on the casing and communicated through the second compartment. Therefore, the liquid driving unit and the cooling plate module can be advantageously integrated into the casing while the duct is reduced to achieve compact space. Moreover, the overall structure achieves liquid storing, circulating and heat conveying function.

  • Publication number: 20060187069
    Abstract: An alarm device for use in a liquid circulation system. The alarm device includes an optical detection unit, which includes an optical emitter that generates light beam to penetrate through a transportation media of the liquid circulation system, and an optical receiver that is positioned opposite to the optical emitter for receiving the light beam penetrated through the transportation media. The alarm device further includes a decision circuit, which is electrically coupled to the optical receiver for excerpting therefrom electronic signals corresponding to the intensity of light beam received by the optical receiver. The decision circuit further determines whether the transportation media is in a normal state. If the transportation media is in an abnormal state, a control signal is generated to drive the alarm sending out alert messages. The alarm device described above is assembled in a box and is securely installed to a predetermined position of the transportation media of the liquid circulation system.
