Abstract

Provided is a heat conversion device, including: a housing; a thermoelectric module received in the housing and including a thermoelectric semiconductor between substrates disposed to face each other; a first temperature conversion portion and a second temperature conversion portion disposed between the substrates, respectively; and a heat reduction portion adopted to guide a part of a fluid flowing in the housing and passing through the first temperature conversion portion to the second temperature conversion portion.

First claim

What is claimed is:

1. A heat conversion device, comprising:
a housing;
a thermoelectric module received in the housing;
a plurality of portions received in the housing;
a first temperature conversion portion and a second temperature conversion portion received in the housing; and
a fluid received in the housing;
wherein the housing comprises:
an injection portion located at a first distal end of the housing,
an outlet portion located at the first distal end of the housing, and
a discharging portion located at a second distal end of the housing opposite to the first distal end of the housing;
wherein the thermoelectric module comprises:
a second substrate disposed on the second temperature conversion portion,
a thermoelectric semiconductor disposed on the second substrate, and
a first substrate disposed on the thermoelectric semiconductor;
wherein the first temperature conversion portion is disposed on the first substrate,
wherein the plurality of the portions comprises:
a first portion disposed extending from a second distal end of the first substrate to a portion of the second distal end of the housing and in contact with the second distal end of the first substrate and the portion of the second distal end of the housing,
a second portion disposed extending from the first portion to a second distal end of the second substrate and in contact with the first portion and the second distal end of the second substrate,
a third portion disposed extending from a first distal end of the first substrate opposite to the second distal end of the first substrate to a portion of the first distal end of the housing and in contact with the first distal end of the first substrate and the portion of the first distal end of the housing, and
a fourth portion disposed extending from a first distal end of the second substrate opposite to the second distal end of the second substrate to a portion of the first distal end of the housing and in contact with the first distal end of the second substrate and the portion of the first distal end of the housing;
wherein the first portion includes communication holes,
wherein the discharging portion includes
a branched pattern portion including a branched pattern at an entrance of the discharging portion of the housing,
wherein the branched pattern is formed to protrude from the entrance of the discharging portion of the housing to reduce a width of the discharging portion,
wherein the branched pattern is formed of at least one protruding pattern having a height smaller than the width of the discharging portion,
wherein the housing and the branched pattern are monolithically formed,
wherein the injection portion receives the fluid from outside of the housing,
wherein the discharging portion is configured to discharge the fluid passing through the injection portion via the first temperature conversion portion,
wherein the communication holes of the first portion are configured to divide the fluid by the branched pattern,
wherein the divided fluid passes the communication holes from a first region formed to communicate with the first temperature conversion portion to a second region formed to communicate with the second temperature conversion portion,
wherein the outlet portion is configured to discharge a part of the fluid passing through the injection portion via the second temperature conversion portion, and
wherein the thermoelectric semiconductor is spaced apart from the fluid by the first substrate, the second substrate, the first portion, the second portion, the third portion, and the fourth portion.

2. The heat conversion device of claim 1 , wherein the branched pattern has an inclination angle inclined toward a traveling direction of the fluid.

3. The heat conversion device of claim 1 , wherein the reduction flow passage is provided between the housing and the thermoelectric module and is configured to have a width that reduces gradually toward a lower part at a position of the discharging portion.

4. The heat conversion device of claim 1 , wherein at least one of the portions has a plate-shaped structure.

5. The heat conversion device of claim 4 , wherein at least one of the communication holes adjusts an amount of the fluid flowing in the reduction flow passage.

6. The heat conversion device of claim 1 , wherein each of the first temperature conversion portion and the second temperature conversion portion comprises a heat transfer member disposed to be adjacent to the first and second substrates and coming into contact with the fluid.

7. The heat conversion device of claim 6 , wherein the heat transfer member comprises: a heat-radiating substrate having a first flat surface in surface contact with the fluid and a second flat surface opposite to the first flat surface; and at least one flow pattern that forms a fluid flow passage in the heat-radiating substrate in a flowing direction of the fluid.

8. The heat conversion device of claim 7 , wherein the flow pattern is configured such that a curvature pattern having a fixed pitch in a lengthwise direction of the substrate is implemented.

9. The heat conversion device of claim 8 , further comprising resistance patterns protruding from a surface of the heat-radiating substrate on a surface of the flow pattern.

10. The heat conversion device of claim 9 , wherein the resistance patterns comprise a plurality of heat-radiating pins protruding in one side direction on the heat-radiating substrate.
