the condenser. A receiver dryer has an inlet comected to an outlet of the condenser. An outside expansion valve has an inlet connected to an outlet of the receiver dryer through a first passage. An outside evaporator has both an inlet connected to an outlet of the outside expansion valve and an outlet comected to an inlet of the compressor through a second passage. An inside evaporator is disposed in the air duct at a position upstream of the condenser. An inside expansion valve has both an inlet connected to the first passage and an outlet connected to an inlet of the inside evaporator. A coolant distributing circuit is further employed which feeds the inside evaporator with at least a part of coolant discharged from the receiver dryer when the coolant pressure in the inside evaporator exceeds a predetermined degree.
additional layers of plastic and optional wicking are attached to an otherwise exposed surface of the bottom plate. The heat pipe is narrow and can thus be installed in existing space proximate to a heat generating component, flexing and/or elastically deforming as necessary to facilitate installation. Further, the heat pipe can be bent, to conform to the shape of the component.

5560423 FLEXIBLE HEAT PIPE FOR INTEGRATED CIRCUIT COOLING APPARATUS Larson Ralph; Phillips Richard Bolton, MA, UNITED STATES assigned to Aavid Laboratories IllC
A heat pipe which is flexible and thus conformable to the space in which it is to be deployed consists of two or three layers, namely, a relatively thin, highly conductive plate as a bottom layer, a plastic sheet as a top layer and wicking as an optional middle layer. The bottom plate has a relatively high modulus of elasticity and it is stiff, yet ductile. It is preferably made of metal, such as aluminum, or a plastic sheet or plate. To manufacture the heat pipe, the bottom and top layers are aligned, with the wicking between them, and sealed together around three edges. Liquid coolant is then added and the fourth edge is sealed. The sealing is preferably performed by heat sealing. The heat pipe may include heat-dissipating fms or ridges on the end of the pipe that operates as a condenser. The opposing end of the pipe, which acts as the evaporator, is positioned proximate to a heat-generating component. In an alternative embodiment,
A catalytic reaction apparatus for carrying out an exothennic catalytic reaction includes a first vessel for containing a first raw material for the exothermic catalytic reaction; a second vessel for containing a second raw material for the exothermic catalytic reaction; a reaction vessel for carrying out therein the exothermic catalytic reaction which is connected to the first and second vessels and receives the fmt and second raw materials for the exothermic catalytic reaction, the reaction vessel having first and second regions respectively containing first and second catalysts having respective activities different from each other so that the first and second regions have different catalytic performances from one another; a first heat exchanger associated with the reaction vessel and containing a heating medium flowing through the fast heat exchanger so that the heating medium receives heat generated by the exothennic reaction in the reaction vessel; a third vessel connected to the first heat exchanger for containing said heating medium and sending the heating medium to the first heat exchangers; a second heat exchanger connected to the first heat exchanger for receiving the heating medium and transferring heat to a heat receptor arranged in the second heat exchanger; a fourth vessel connected to the reaction vessel for receiving reaction products produced in the reaction vessel; and a passage element connected to the fourth vessel for returning the heating medium from the second heat exchanger to the third vessel.
