Refrigerant module

Abstract

The present disclosure relates to a refrigerant module, and more specifically, in a refrigerant module including a manifold in which a plurality of fluid flow paths are formed, and at least one heat exchanger which is coupled to a lower side of the manifold in a direction of gravity and in which a fluid flows and is heat-exchanged while communicating with the flow path through an inlet and an outlet, the refrigerant module is configured so that the inlet and the outlet of the heat exchanger are located to be biased to one side, and thus the heat exchanger and the refrigerant manifold have a structure for preventing oil and refrigerant from being trapped therein.

What is claimed is: 
     
         1 . A refrigerant module comprising a manifold in which a plurality of fluid flow paths are formed, and at least one heat exchanger which is coupled to a lower side of the manifold in a direction of gravity and in which a fluid flows and is heat-exchanged while communicating with the flow path through an inlet and an outlet,
 wherein, in the refrigerant module, the manifold and the inlet and the outlet of the heat exchanger through which the fluid flows are disposed to be biased to a lower side of the refrigerant module in order to prevent the fluid flowing therein from being trapped.   
     
     
         2 . The refrigerant module of  claim 1 , wherein the manifold includes:
 a flow path part located at a lower side thereof and having a plurality of fluid flow paths formed through straight processing disposed in a polygonal shape; and   a valve block located above the flow path part and for installation of a valve that controls a flow of the flowing fluid.   
     
     
         3 . The refrigerant module of  claim 1 , wherein the heat exchanger has the inlet and the outlet disposed adjacent to each other by an assembly port, and the assembly port is located at a farthest side from the manifold. 
     
     
         4 . The refrigerant module of  claim 3 , wherein the assembly port is configured so that the inlet and outlet are disposed in parallel in a horizontal direction with respect to a ground. 
     
     
         5 . The refrigerant module of  claim 3 , wherein the at least one of the inlet and the outlet is located at a corner of the heat exchanger. 
     
     
         6 . The refrigerant module of  claim 3 , wherein the heat exchanger forms a fluid flow in which a fluid introduced through the inlet circulates along a flat surface of the heat exchanger, moves downward in the direction of gravity, and then is discharged through the outlet. 
     
     
         7 . The refrigerant module of  claim 6 , wherein the heat exchanger minimizes a pressure drop of the fluid by the fluid flow moving downward in the direction of gravity, thereby preventing oil and refrigerant from being trapped. 
     
     
         8 . The refrigerant module of  claim 5 , wherein the heat exchanger forms a fluid flow in which a fluid introduced through the inlet circulates clockwise or counterclockwise along a flat surface of the heat exchanger and then is discharged through the outlet. 
     
     
         9 . The refrigerant module of  claim 2 , wherein the heat exchanger is coupled to the flow path part and disposed to overlap one surface of a polygonal shape portion formed by the flow paths. 
     
     
         10 . The refrigerant module of  claim 9 , wherein the heat exchanger has the inlet and the outlet disposed adjacent to each other by an assembly port, and the assembly port is located at a lower end away from the valve block. 
     
     
         11 . The refrigerant module of  claim 2 , wherein the flow path part includes a refrigerant port that is formed to correspond to an assembly port configured so that the inlet and the outlet are disposed adjacent to each other and includes the inlet and the outlet through which a fluid is introduced into and discharged from the flow path part. 
     
     
         12 . The refrigerant module of  claim 11 , wherein the refrigerant port is formed at a connection point between the plurality of straight fluid flow paths. 
     
     
         13 . The refrigerant module of  claim 11 , wherein the flow path part controls a flow of the fluid between the flow path part and a heat exchanger by the refrigerant port. 
     
     
         14 . The refrigerant module of  claim 1 , wherein the heat exchanger is a power electronics chiller (PE chiller). 
     
     
         15 . The refrigerant module of  claim 2 , wherein the manifold is disposed so that the plurality of straight fluid flow paths are formed at angles.
