Liquid supercooling system

Abstract

A liquid supercooling system may include a suction pipe that has a spiral groove around the outer circumference thereof and connects an evaporator with a compressor, a liquid pipe that connects a condenser with an expansion pipe, a heat exchange pipe in which the suction pipe is inserted and of which one end is connected with the liquid pipe such that heat can be exchanged between the suction pipe and the liquid pipe, and a connection block, of which one side is connected to the liquid pipe and of which the other side is connected to the suction pipe and the heat exchange pipe.

1 . A liquid supercooling system comprising:
 a suction pipe that has a spiral groove around the outer circumference thereof and connects an evaporator with a compressor;   a liquid pipe that connects a condenser with an expansion pipe;   a heat exchange pipe in which the suction pipe is inserted and of which one end is connected with the liquid pipe such that heat can be exchanged between the suction pipe and the liquid pipe; and   a connection block, of which one side is connected to the liquid pipe and of which the other side is connected to the suction pipe and the heat exchange pipe.   
     
     
         2 . The liquid supper cooling system according to  claim 1 , wherein the suction pipe and the heat exchange pipe are disposed in the same line and the liquid pipe is coupled to the connection block in parallel with the suction pipe 
     
     
         3 . The liquid supper cooling system according to  claim 1 , wherein a channel through which coolant flows from the liquid pipe and an internal space connected to the channel are formed in advance in the connection block, the suction pipe and the heat exchange pipe being connected to the internal space. 
     
     
         4 . The liquid supper cooling system according to  claim 3 , wherein the channel in the connection block is formed to surround the suction pipe and communicate with the spiral groove of the suction groove. 
     
     
         5 . The liquid supper cooling system according to  claim 3 , wherein the suction pipe and the heat exchange pipe are disposed through the internal space in the same line and the liquid pipe is coupled to the channel in the connection block in parallel with the suction pipe 
     
     
         6 . The liquid supper cooling system according to  claim 3 , wherein the channel is formed in a curve shape. 
     
     
         7 . The liquid supper cooling system according to  claim 3 , wherein a portion of the internal space has a relatively large diameter and receives the heat exchange pipe therein, such that the coolant flows inside the internal space while covering and rotating along the spiral groove of the suction pipe.
