Abstract: A loop-type heat exchange device (10) is disclosed, which includes an evaporator (20), a condenser (40), a vapor conduit (30) and a liquid conduit (50). The evaporator contains therein a working fluid. The working fluid in the evaporator evaporates into vapor after absorbing heat, and the generated vapor flows, via the vapor conduit, to the condenser where the vapor releases its latent heat of evaporation and is condensed into condensate. The condensate then returns back, via the liquid conduit, to the evaporator to thereby form a heat transfer loop. The condenser defines therein a chamber, and a plurality of heat-exchange pins is provided inside the chamber for effectively exchanging heat with the vapor entering into the condenser.

Abstract: The present invention provides a control system employing a single solenoid valve operable to provide a variable fluid flow to effect cooling if the motor/generator assemblies contained within an electrically variable hybrid transmission. The control system of the present invention selectively controls the cooling of at least one motor/generator assembly of an electronically variable hybrid transmission by selectively controlling valves of various types and configurations.

The operating body includes a pole connecting the supporting members, a pivot member pivotably attached to the pole, and at least a spring member encircling the pole. The pivot member includes a pressing portion adapted for pressing the heat sink. One end of the spring member is fixed on one of the supporting members, and the other end of the spring member is secured with the pivot member. The pivot member is pivotable from a first position to a second position under action of a force and returns back to the first position from the second position under action of the spring member after withdrawing the force.

Abstract: The present invention provides apparatuses and methods for controlling the temperature of a process fluid. An exemplary apparatus in accordance with the present invention comprises a process fluid tank, a cryogenic fluid tank, and a plurality of heat transfer plates for transferring heat from a process fluid in the process fluid tank to a cryogenic fluid in the cryogenic fluid tank. Heating devices can be used to heat a portion of one or more of the heat transfer plates to regulate the transfer of heat from a process fluid in the process fluid tank to a cryogenic fluid in the cryogenic fluid tank.

Abstract: In a vehicle air conditioner, a rotary door is disposed to open and close a foot opening portion and an inlet port of a face opening portion and a defroster opening portion. The rotary door includes a curvature outer peripheral portion for opening and closing the inlet port of the face opening portion and the foot opening portion, end plate portions located at two ends of the outer peripheral portion in an axial direction to open and close the foot opening portion, and shaft portions located at the end plate portions to be rotatably supported in the air conditioning case. The rotary door and the air conditioning case are provided such that a clearance between the inner wall of the air conditioning case and the outer peripheral portion of the rotary door is changed to be different between a bi-level air outlet mode and a foot/defroster air outlet mode.

Abstract: A motor vehicle air conditioning system including a Coanda effect air distributor device and mixing means which allow to vary the temperature of the air available to the different outlet conduits of the distributor device for the same setting of the means for regulating the temperature of the system. In this way, for a same setting of the temperature regulating means, the air conveyed to the outlets situated at the base of the windshield is at a higher temperature than the air conveyed to the other outlets and in particular to those adjacent to the floor of the motor vehicle passenger compartment. Preferably, a third, still lower temperature level is available to the outlets situated in the front part of the dashboard of the motor vehicle in the direction of the motor vehicle occupants.

Abstract: An apparatus and method for compressing gas refrigerant using two different compressors operated alternatively in a series or parallel mode for obtaining two different compression ratios and thereby provide efficient operation for both a relatively lower suction pressure and a relatively higher suction pressure. This system avoids an unbalanced mass flow rate when the compressors are operated in series by unloading a downstream one of the compressors. When operated in the series mode, refrigerant is bypassed back to a suction inlet of the downstream compressor during a portion of a compression stroke of the downstream compressor for equalizing the mass flow rate through the two compressors.

Abstract: A heat exchanger assembly includes a core having first and second header tanks covered by tank caps. A pair of core reinforcing members presenting terminal ends extend between the first and second header tanks. A least one tab and an opening for receiving the tab are used for connecting the core reinforcing members to the tank caps.

Abstract: A control is provided for a first HVAC unit that is coupled to a common duct shared with at least one other HVAC unit. The control comprises a twinning connection for communication with at least a second control of another HVAC unit, and a voltage signal applied to the twinning connection. The control further comprises a switching means for switching the voltage signal to ground. A microcomputer for monitoring the twinning connection and for controlling the switching means is configured to actuate the switching means to switch the voltage at the twinning connection to ground for a predetermined time period to communicate a blower speed for the first HVAC unit. The microcomputer monitors the twinning connection to sense the duration that the voltage at the twinning connection is being conducted to ground, and responsively controls the speed of the first HVAC blower according to the prescribed blower speed corresponding to the sensed duration.

Abstract: A heat dissipating structure having different compactness assembled from a plurality of small heat dissipating fins, thereby forming heat dissipation areas having different spacing. The heat dissipating fins are stamp formed from single strips, and spacing of each of the heat dissipating fins is predetermined when assembling to constitute the structure. The heat dissipating fins are completed from a single stamping, and can be assembled to form heat dissipation areas of different spacing to accommodate a cool air flow being fanned from different oriented fans, thereby reducing obstruction and disturbance of the air flow and rapidly and smoothly guiding the air flow to other heat dissipating fins. Moreover, the heat dissipating structure enlarges area of heat circulation, thereby augmenting speed of heat diffusion, improving heat dissipation effect on heat emitting from computer electronic components, and enhancing functionality of the fan.

Abstract: A refrigerant evaporator includes a tank constituted by a tank portion and a header plate. The tank portion includes refrigerant collecting portions for guiding the refrigerant passed through a first path to the ends of the tank in the right-and-left direction and refrigerant distributing portions for guiding the refrigerant to the tubes forming a second pass. The header plate has refrigerant collecting/distributing space for the tubes. Side tanks are arranged to cover open portions at the ends of the tank in the right-and-left direction, and to spatially connect the flow passages. Separators are provided at portions where the flow passages are to be spatially blocked to constitute a front-and-rear right-and-left cross path. An increased sectional area of flow passages is obtained at the refrigerant flow corner portions relying upon a simple constitution, to decrease the pressure loss on the refrigerant side in the tank and to enhance performance.
