Evaporator

Abstract

An evaporator has an outer housing with a first hole, a second hole and an outlet on a bottom thereof and an inlet and a dissipating hole at a top thereof. An evaporating device is received in the outer housing, which has fin assemblies, boards between the fin assemblies, two lateral plates and a refrigerant tube. Each board has two flat sides and two curved sides, and the lateral plates are attached on the flat sides of the boards respectively. Each board has a gap at an end thereof, which the gaps of the neighboring boards are arranged at opposite sides respectively. The refrigerant tube is twisted and runs through the fin assemblies and the boards. The refrigerant tube has a refrigerant inlet and a refrigerant outlet at opposite ends to be extruded out of the outer housing via the fist hole and the second hole respectively.

1 . An evaporator, comprising: 
 an outer housing having a first hole, a second hole and an outlet between the first hole and a second hole on a bottom thereof and an inlet and a dissipating hole at a top thereof;    an evaporating device received in the outer housing, which has a plurality of fin assemblies, a plurality of boards between the fin assemblies, two lateral plates and a refrigerant tube;    wherein each of the boards has two substantially parallel flat sides and two curved sides, and the lateral plates are attached on the flat sides of the boards respectively to shield the fin assemblies, such that each of the fin assemblies only has one side in and one side out;    wherein each of the boards has a gap at an end thereof, which the gaps of the neighboring boards are arranged at opposite sides respectively, and a sealing board is fixed on top ends of the lateral plates above the top board, which has a tube connected to the inlet of the outer housing;    wherein the refrigerant tube is twisted and runs through the fin assemblies and the boards in a vertical orientation, which has a refrigerant inlet and a refrigerant outlet at opposite ends thereof to be extruded out of the outer housing via the fist hole and the second hole respectively for circulation of a refrigerant, and water in the outer housing is exhausted out via the outlet.    
   
   
       2 . The evaporator as defined in  claim 1 , wherein two passageways are formed in the outer housing between the evaporating device and an interior sidewall of the outer housing, which a waste heat is exhausted out of the outer housing via the passageways and the dissipating hole.
