Cooling apparatus

Abstract

A cooling apparatus that cools an HV appliance heat source includes: a compressor for circulating a coolant; a condenser for condensing the coolant; an expansion valve that decompresses the coolant that has been condensed by the condenser; an evaporator for evaporating the coolant that has been decompressed by the expansion valve; and a coolant passageway through which the coolant that moves from an outlet of the condenser toward an inlet of the expansion valve flows. The coolant passageway includes a passageway-forming portion that forms a portion of the coolant passageway. The cooling apparatus further includes a coolant passageway that is disposed in parallel with the passageway-forming portion, and that circulates the coolant via the HV appliance heat source.

1 . A cooling apparatus that cools a heat generation source, comprising:
 a compressor that circulates a coolant;   a condenser that condenses the coolant;   a decompressor that decompresses the coolant that has been condensed by the condenser;   an evaporator that evaporates the coolant that has been decompressed by the decompressor;   a first passageway through which the coolant that moves from an outlet of the condenser toward an inlet of the decompressor flows, and which includes a passageway-forming portion that forms a portion of the first passageway, and   a second passageway which is connected in parallel with the passageway-forming portion, and which is provided with the heat generation source, and in which the coolant flows via the heat generation source.   
     
     
         2 . The cooling apparatus according to  claim 1 , further comprising
 a flow control valve that is disposed on the passageway-forming portion and that adjusts amount of flow of the coolant flowing through the passageway-forming portion and the amount of flow of the coolant flowing through the second passageway.   
     
     
         3 . The cooling apparatus according to  claim 1 , further comprising:
 a third passageway through which the coolant that moves from an outlet of the compressor toward an inlet of the condenser flows; and   a communication passageway that provides communication between the third passageway and a downstream side of the second passageway relative to the heat generation source.   
     
     
         4 . The cooling apparatus according to  claim 3 , further comprising
 a switching valve that switches state of communication between the downstream side of the second passageway relative to the heat generation source and each of the first passageway and the third passageway.   
     
     
         5 . The cooling apparatus according to  claim 3 , wherein the heat generation source is disposed below the condenser. 
     
     
         6 . The cooling apparatus according to  claim 1 , further comprising
 another condenser disposed on the first passageway, wherein   the passageway-forming portion is provided between the condenser and the another condenser.   
     
     
         7 . The cooling apparatus according to  claim 6 , wherein
 the condenser is higher in heat release capability of releasing heat from the coolant than the another condenser.   
     
     
         8 . The cooling apparatus according to  claim 3 , further comprising
 a fan that blows air to the condenser.   
     
     
         9 . A cooling apparatus that cools a heat generation source, comprising:
 a compressor that circulates a coolant on a circulation path;   a condenser that condenses the coolant on the circulation path;   a decompressor that decompresses, on the circulation path, the coolant that has been condensed by the condenser;   an evaporator that evaporates, on the circulation path, the coolant that has been decompressed by the decompressor;   a first passageway which is a portion of the circulation path, and through which the coolant that moves from an outlet of the condenser toward an inlet of the decompressor flows, and which includes a passageway-forming portion as a portion of the first passageway; and   a second passageway which is connected in parallel with the passageway-forming portion, and which is provided with the heat generation source, and in which the coolant flows via the heat generation source.
