Evaporator and cooling device

Abstract

Service life of the compressor is extended. The evaporator is provided with the housing having the suction port connectable to the suction portion of the compressor in order to evaporate at least part of a droplet or misty working fluid in the housing by a suction effect of the compressor through the suction port, comprising a filter installed in the housing, the filter dividing a space in the housing into the first space for generating the droplet or misty working fluid and the second space for communicating with the suction port, the filter being inclined away from the suction port as advancing upward, and the filter transmitting therethrough vapor resulting from evaporation of the droplet or misty working fluid while capturing the droplet or misty working fluid.

1 . An evaporator provided with a housing having a suction port connectable to a suction portion of a compressor in order to evaporate at least part of a droplet or misty working fluid in the housing by a suction effect of the compressor through the suction port, comprising;
 a filter installed in the housing, the filter dividing a space in the housing into a first space for generating the droplet or misty working fluid and a second space for communicating with the suction port, the filter being inclined away from the suction port as advancing upward, the filter transmitting therethrough vapor resulting from evaporation of the droplet or misty working fluid while capturing the droplet or misty working fluid.   
     
     
         2 . An evaporator provided with a housing having a suction port connectable to a suction portion of a compressor in order to evaporate at least part of a droplet or misty working fluid in the housing by a suction effect of the compressor through the suction port, comprising;
 a filter installed in the housing, the filter dividing a space in the housing into a first space for generating the droplet or misty working fluid and a second space for communicating with the suction port, the filter transmitting therethrough vapor resulting from evaporation of the droplet or misty working fluid while capturing the droplet or misty working fluid, wherein   the filter is divided into a plurality of filter members disposed in a vertical direction, each of the filter members being inclined away from the suction port as advancing upward.   
     
     
         3 . The evaporator according to  claim 2 , further comprising;
 a receiving plate portion arranged between two adjacent filter members disposed in the vertical direction, the receiving plate portion receiving the working fluid captured by an upper filter member thereof and flowing downward; and   an erected portion erected on the receiving plate portion at a position closer to the suction port than the upper filter member.   
     
     
         4 . The evaporator according to  claim 3 , wherein the receiving plate portion is inclined downward from the second space to the first space. 
     
     
         5 . The evaporator according to  claim 2 , further comprising;
 a receiving plate portion arranged between two adjacent filter members disposed in the vertical direction, the receiving plate portion receiving the working fluid captured by an upper filter member thereof and flowing downward, wherein   the receiving plate portion is inclined downward from the second space to the first space.   
     
     
         6 . The evaporator according to  claim 3 , wherein;
 the receiving plate portion has a first end portion and a second end portion closer to the suction port than the first end portion; and   the receiving plate portion is inclined downward from the second end portion to the first end portion.   
     
     
         7 . A cooling device, comprising the evaporator according to  claim 1 , wherein cooling is performed by using evaporation heat obtained when at least part of the droplet or misty working fluid is evaporated. 
     
     
         8 . The evaporator according to  claim 5 , wherein;
 the receiving plate portion has a first end portion and a second end portion closer to the suction port than the first end portion; and   the receiving plate portion is inclined downward from the second end portion to the first end portion.   
     
     
         9 . A cooling device, comprising the evaporator according to  claim 2 , wherein cooling is performed by using evaporation heat obtained when at least part of the droplet or misty working fluid is evaporated.
