  • FIG. 4 is a diagram illustrating a tube and a thermoelectric element of a TED heat exchanger, according to various embodiments of the present invention.
  • the TED heat exchanger includes: a plate part configured to have a cooling tube 100 and a heat radiation tube 200 which are formed in a tube shape having fluid passages formed therein, in which the cooling tube 100 and the heat radiation tube 200 are prepared in plural and continuously disposed and the cooling tubes 100 and the heat radiation tubes 200 are alternately disposed to each other; a cooling inflowing tank 310 and a cooling discharging tank 320 configured to be connected to an inlet and an outlet of the cooling tube 100 , respectively; a heat radiation inflowing tank 410 and a heat radiation discharging tank 420 configured to be connected to an inlet and an outlet of the heat radiation tube 200 , respectively; and a thermoelectric element 500 configured to have a cooling surface and a heat radiation surface and be disposed between the cooling tube 100 and the heat radiation tube 200 , in which the cooling surface is attached to the cooling tube 100 and the heat radiation surface is attached to the heat radiation tube 200 .
  • FIG. 4 illustrates the tube and the thermoelectric element, in which the plate part according to the exemplary embodiment of the present invention is configured of a plurality of the tubes which may be classified into the cooling tube 100 and the heat radiation tube 200 .
  • Each tube is formed in the tube shape which has the fluid passages formed therein and as illustrated in FIG. 4 , a pair of upper and lower plates 10 is coupled with each other to form an inner space, in which the inner space is provided with pins 20 which are heat-exchanged with a fluid and the pins 20 may be coupled with each other by a brazing method, and the like.
  • the cooling tube 100 and the heat radiation tube 200 are each prepared in plural and continuously disposed. Further, in the overall state in which the cooling tubes 100 and the heat radiation tubes 200 are coupled with each other as illustrated in FIG. 1 , the cooling tubes 100 and the heat radiation tubes 200 are alternately disposed to each other.
  • thermoelectric element 500 is disposed between the cooling tube 100 and the heat radiation tube 200 which are alternately disposed to each other.
  • the thermoelectric element is covered and thus is not illustrated, but it may be understood from FIG. 4 that the thermoelectric element 500 is disposed between the cooling tube 100 and the heat radiation tube 200 .
  • the cooling surface of the thermoelectric element 500 is attached to the cooling tube 100 and the heat radiation surface is attached to the heat radiation tube 200 , such that a fluid flowing in the cooling tube 100 is sufficiently cooled through the cooling surfaces of the thermoelectric elements 500 disposed at upper and lower portions but a fluid flowing in the heat radiation tube 200 heat-sinks the heat radiation surface of the upper and lower thermoelectric elements 500 .
  • an inlet 101 and an outlet 102 of the cooling tube 100 may be formed to be disposed at an opposite side to each other based on a center line a extended to a longitudinal direction of the cooling tube 100 .
  • an inlet 201 and an outlet 202 of the heat radiation tube 200 may be formed to be disposed at an opposite side to each other based on a center line b extended to a longitudinal direction of the heat radiation tube 200 . Therefore, the fluid flowing in the cooling tube 100 and the heat radiation tube 200 may sufficiently flow over the whole area or substantially the whole area through a channel obliquely formed and may be conducted.
  • the inlet 201 of the heat radiation tube 200 is disposed at the outlet 102 side of the cooling tube 100 , such that a finally discharged cooling fluid may maximally keep a cooled state.
  • the inlets or the outlets of the cooling tube 100 and the heat radiation tube 200 may be formed to be disposed at an opposite side to each other based on the center lines a and b extended to the longitudinal directions of the tubes.
  • the cooling inflowing tank 310 or the cooling discharging tank 320 is adjacently disposed at an opposite side to each other based on center lines a and b extended to the longitudinal direction of tubes of the heat radiation inflowing tank 410 or the heat radiation discharging tank 420 and thus may be connected to the inlets or the outlets of the cooling tube 100 or the heat radiation tube 200 , respectively.
  • all of the plurality of inlets 201 of the heat radiation tube 200 may be connected to the heat radiation inflowing tank 410 . Further, all of the plurality of outlets 202 of the heat radiation tube 200 may be connected to the heat radiation discharging tank 420 .
  • the heat radiation fluid for heat radiation are simultaneously introduced from the inlet 201 of one side and simultaneously discharged to the outlet 202 of the other side and thus a plurality of straight channels are formed, such that a flow velocity is fast, thereby performing the fast heat radiation and maximally bringing a radiated quantity of heat.
  • the inlets and the outlets of the plurality of cooling tubes 100 communicate with each other through the cooling inflowing tank 310 or the cooling discharging tank 320 , such that the plurality of cooling tubes 100 may form a series of continuous channels. That is, in the case of the heat radiation, a fast flow velocity, a large flow rate, and the heat radiation are performed through the plurality of parallel channels, while in the case of the cooling, the channels are continued in zigzag to add cooling to the continuous cooling, such that the flow rate and the flow velocity are small but the cooling is increased so much.
  • the plurality of cooling tubes 100 are divided into a first cooling set A having a fluid flow in one side and a second cooling set B having a fluid flow in the other side, in which the first cooling set A and the second cooling set B may be configured to have an inlet and an outlet disposed in an opposite direction to each other.
  • the inlet of the first cooling set A may communicate with the outlet of the second cooling set B in the cooling inflowing tank 310 or the cooling discharging tank 320 and the outlet of the first cooling set A may communicate with the inlet of the second cooling set B in the cooling inflowing tank 310 or the cooling discharging tank 320 .
  • the first cooling set A or the second cooling set B does not communicate with the cooling sets of the other side.
  • the cooling inflowing tank 310 and the cooling discharging tank 320 are each connected to ends of the cooling tube 100 and the insides of the cooling inflowing tank 310 and the cooling discharging tank 320 are provided with partition walls 314 and 324 to form a zigzag channel through which the fluid continuously flows in the first cooling set A and the second cooling set B.
  • the partition walls 314 and 324 are each prepared at different positions of the cooling inflowing tank 310 and the cooling discharging tank 320 one by one and thus the channel of first cooling set A—second cooling set B—first cooling set A may be formed.
  • the cooling fluid is continuously cooled and thus the temperature of the finally discharged cooling fluid is very low, while the heat radiation fluid implements the fast heat radiation through the plurality of parallel channels and thus the performance of the heat exchanger is finally very excellent.
  • a method of disposing the cooling inflowing tank 310 and the cooling discharging tank 320 and disposing the partition walls 314 and 324 therein may be used, but a method of forming one channel, having the plurality of cooling inflowing tanks or cooling discharging tanks may also be used. That is, the cooling inflowing tank or the cooling discharging tank is designed to be divided into the plurality of tanks, and as a result it is possible to obtain the same or similar effect as the effect obtained by dividing the cooling inflowing tank or the cooling discharging tank by the partition wall. However, in this case, there is a problem in that the number of parts is increased and the assembling time may be increased.
  • the TED heat exchanger may sufficiently reduce the temperature of the cooling fluid and rapidly discharge the heat radiation fluid in the heat exchanger using the thermoelectric element, thereby remarkably increasing the performance of the thermoelectric element. Therefore, the overall coefficient of performance (COP) performance of the heat exchanger may be very greatly improved.
