Heat exchanger with thermoelectric module and system for managing heat of battery including same

Abstract

A heat exchanger with a thermoelectric module according to the present disclosure includes: a first heat exchanger including a first heat sink provided with a first base plate and first heat dissipation pins, a first thermoelectric module located over the first heat sink and performing heat absorption and heat dissipation, a plate-shaped first cooling plate located over the first thermoelectric module and having a flow channel through which coolant flows, and a first cover covering top of the first cooling plate; and a second heat exchanger having the same structure as the first heat exchanger and located under the first heat exchanger to be symmetrical with the first heat exchanger.

1 . A system for managing heat of a battery including a heat exchanger with a thermoelectric module, the system comprising:
 a battery thermal management device including a coolant flow channel through which coolant flows for cooling down or heating up a battery module, a coolant inlet portion into which the coolant is introduced, and a coolant outlet portion from which the coolant is withdrawn after being circulated through the coolant flow channel; and   the heat exchanger with the thermoelectric module, the heat exchanger being configured such that the coolant withdrawn from the coolant outlet portion of the battery thermal management device is introduced into the heat exchanger, and the introduced coolant undergoes cooling down or heating up and is then introduced into the coolant inlet portion of the battery thermal management device, whereby the battery module is cooled down or heated up.   
     
     
         2 . The system of  claim 1 , wherein the heat exchanger with the thermoelectric module includes:
 a first heat exchanger including a first heat sink provided with a first base plate and first heat dissipation pins, a first thermoelectric module located over the first heat sink and performing heat absorption and heat dissipation, a plate-shaped first cooling plate located over the first thermoelectric module and having a flow channel through which coolant flows, and a first cover covering top of the first cooling plate; and   a second heat exchanger having the same structure as the first heat exchanger and located under the first heat exchanger to be symmetrical with the first heat exchanger.   
     
     
         3 . The heat exchanger of  claim 2 , wherein the second heat exchanger includes:
 a second heat sink provided with a second base plate and second heat dissipation pins and configured such that the second heat dissipation pins are disposed to face the first heat dissipation pins;   a second thermoelectric module located under the second heat sink and performing heat absorption and heat dissipation;   a plate-shaped second cooling plate located under the second thermoelectric module and having a flow channel through which the coolant flows; and   a second cover covering bottom of the second cooling plate.   
     
     
         4 . The system of  claim 3 , wherein the first cooling plate includes a first inlet into which the coolant withdrawn from the coolant outlet portion of the battery thermal management device is introduced, and a first outlet from which the coolant is withdrawn after being circulated through the flow channel of the first cooling plate, and
 the second cooling plate includes a second inlet into which the coolant withdrawn from the first outlet is introduced, and a second outlet from which the coolant is withdrawn after being circulated through the flow channel of the second cooling plate.   
     
     
         5 . The system of  claim 4 , further comprising:
 a connection pipe connecting the first outlet and the second inlet to each other.   
     
     
         6 . The system of  claim 4 , further comprising:
 a coolant storage part storing the coolant withdrawn from the second outlet; and   a pump connected to the coolant storage part and to the coolant inlet portion of the battery thermal management device to introduce the coolant stored in the coolant storage part into the coolant inlet portion.
