Heat exchanger for a cooling system

Abstract

A heat exchanger for a cooling system, suitable for a compact heat exchanging system having a compressor and a radiator by minimizing an occupied volume of the heat exchanger, including a piping structure simplified by integrating a cooling medium injection pipe and a cooling medium exhaust pipe into a single piping structure, thereby preventing water leakage through a pipe connecting portion. Cooling performance of a cooling system having the heat exchanger is improved and thermal efficiency per an electric heat area in the heat exchanger is highly enhanced by disposing a spiral partition between a heat exchanging part, a heat exchanger pipe and a capillarity tube in a main body of the heat exchanger so as to guide a mixed flow of water and cooling medium in the creation of the vortex or swirling motion.

1 . A heat exchanger for a cooling system comprising a main body to which a cooling water inlet and a cooling water outlet are connected, in which a heat exchanging pipe for circulating a cooling medium is inserted into the main body, which cools water introduced through the cooling water inlet pipe, wherein:
 the main body is constituted of a heat exchanging part for performing a cooling operation by virtue of a heat exchanging pipe and an exhausting passage, wherein the heat exchanging part and the exhausting passage are integrally formed with each other such that they can create a U-shape channel and thereby a certain space is created therein, wherein the cooling water inlet is connected with a one side of an upper end of the main body, which is corresponding to a one end of the heat exchanging part, wherein the cooling water outlet is connected with the other side of the upper end of the main body, which is corresponding to a one end of the exhausting passage, wherein a connecting tube is integrally connected and installed to a front side of the upper end of the main body at a position adjacent to the cooling water inlet, wherein the heat exchanger pipe passes through the connecting tube and continuously it is inserted in the heat exchanging part of the main body, and wherein a capillarity tube for injecting cooling medium and a cooling medium exhausting pipe are inserted into the heat exchanging pipe and then held by virtue of a packing.   
   
   
       2 . The heat exchanger for a cooling system as claimed in  claim 1 , wherein a spiral partition for circulating water in the creation of the vortex or swirling motion, which is introduced into the heat exchanging part via the cooling water inlet, is installed between an inner side surface of the heat exchanging part in the main body and an outer side surface of the heat exchanging pipe. 
   
   
       3 . The heat exchanger for a cooling system as claimed in  claims 1  or  2 , wherein a spiral partition for circulating cooling medium in the creation of the vortex or swirling motion, which is introduced from the capillarity tube to the cooling medium exhausting pipe, is installed between an inner side surface of the heat exchanging pipe and an outer side surface of the capillarity tube.
