Abstract

The present invention relates to a heat exchanger of a heat exchanging system of a cooling and heating device for working fluids (air, water, etc.) using a thermoelectric module. The structure and heat exchange performance determines the performance of the entire cooling and heating system (cooling and heating capacity, overall system efficiency (COP), response time required to reach the target temperature, and response time). The importance of a heat exchanger in a cooling and heating device for cooling and heating a working fluid can be very large. Accordingly, the present invention relates to a heat exchanger of a cooling and heating device using a thermoelectric module among heat exchangers having the cooling and heating device described above.

In order to improve the performance of the heat exchanger (Heat Exchanger) described above, the body of the heat exchanger (Heat Exchanger) is a plurality of deep holes (Deep Hole) that is dense to the metal body of a material (aluminum, copper, etc.) having excellent thermal conductivity Heat exchange conduits are formed, and each heat exchange conduit connects adjacent conduits in a U-shape by end caps at both ends, so that all of the heat exchange conduits configured in the heat exchanger body have one long column. By forming an exchange pipe, a heat exchange pipe of sufficient length necessary for heat exchange between the heat exchanger main body and the working fluid can be secured.

By the above configuration, it is possible to secure a heat exchange pipe having a sufficiently long length for the heat exchange in the small sized heat exchanger, which can greatly reduce the size of the heat exchanger, thereby reducing the size of the entire cooling and heating device, The total mass can be reduced, reducing the response time required for cooling and heating required to reach the target temperature of the working fluid at the first startup, and lowering the amount of heat held by the heat exchanger for more precise temperature control. It can be done.

Description

Heat exchanger using semiconductor thermoelectric device {The Heat Exchanger of Thermoelectric Module}

The present invention relates to a heat exchanger (Heat Exchanger) designed to improve the performance of the entire system in the cooling and heating system of the working fluid using a semiconductor thermoelectric module (Thermoelectric Module).

In general, a heat exchanger is a boiler that transfers low-temperature cold air generated by heat absorption through heat generated from a heat source or phase change of refrigerant to a working fluid (eg, air or water). A typical example is a heat exchanger mounted inside an air conditioner. However, these heat exchangers are usually used as a large space, a large amount of heating and cooling device, there is a disadvantage that it is difficult to locally cool the parts that require a large installation site and locally cooling only the part that needs to be cooled. Therefore, in order to solve the problems as described above, a technique using a thermoelectric element for local cooling has been applied in recent years, and has been presented in Korean Utility Model Registration No. 0217056.

In the above, the thermoelectric semiconductor device is manufactured using the Peltier Effect, and has two different polarities (P type and N type) made of bismuth telluride alloy together with some thermoelectric additives. Many crystals are electrically coupled in series to develop a parallel heat transfer effect when a direct current flows. However, the heat exchanger structure of the prior filed technology is a method of connecting the well-heated metal tube 500 and the U-shaped metal tube 500a as shown in FIG. 4 or by lengthening the length of the tube in the form of a spring. As a method of cooling or heating a fluid that is manufactured and transferred to a heat exchanger through a heat transfer medium, the manufacturing process is complicated, the size is large, takes up a lot of space, and manufacturing cost is high.

The present invention is designed to solve the problems as described above, and relates to a method for constructing a long pipe in a heat exchanger of the smallest possible size. The heat exchanger extrudes a number of deep holes into a wide surface shape in a metal body (for example, aluminum, copper, etc.) that has good thermal conductivity to form a block shape, and each hole has an end at the end of the block. All deep holes formed in the heat exchanger block by being connected to each other by an end cap form a long heat exchange conduit having an inlet and an outlet of one heat exchange conduit. The thermoelectric element is directly attached to the heat exchanger block thus manufactured to raise or lower the temperature of the heat exchanger block so that the working fluid is heated or cooled while passing through the heat exchange conduit.

Since the heat exchanger is so small (as the mass of the heat exchanger itself is small), it reduces the response time for cooling and heating required to reach the target temperature, and is directly attached to the heat exchanger block. By controlling the thermoelectric element, the temperature change of the working fluid during the temperature control can be made quickly. In addition, since the length of the heat exchange pipe is sufficiently long, sufficient heat exchange between the heat exchanger block and the working fluid can be obtained.

In order to achieve the above object, the heat exchanger of the present invention is a heat exchanger designed to minimize the size, maximize the heat exchange efficiency, and to manufacture a simple and precise temperature control method. The deep holes are densely composed of a large surface area and extruded into a long block shape, cut into appropriate sizes to fit the capacity and size of the designed heat exchanger, and manufactured in the form of blocks. Deep holes are connected to each other by end caps at the end of the block so that all seams formed in the heat exchanger block form a long heat exchange passage having one inlet and an outlet. At this time, the end cap is formed with a U-shaped groove so that two seams can form one conduit, so that each deep hole composed of the entire block has one long heat exchange. It is possible to form a conduit so that it is easy to manufacture.

When described in detail by the accompanying drawings a heat exchanger for a thermoelectric element produced by the present invention is as follows.

First, FIG. 1 shows a block diagram of a working fluid (eg, water, air, etc.) cooling apparatus using a thermoelectric element, and includes a space block 110a attached to a heat exchanger main body 110 having a dense and large number of heat exchange conduits. When the thermoelectric element 120 is attached to the thermoelectric element and the electricity is supplied to the thermoelectric element, the cold cool air is transferred to the heat exchanger main body 110 through the space block 110a, and the working fluid introduced through the inlet of the heat exchange conduit heat exchanges. As it passes through the pipeline, it absorbs the heat from the working fluid and lowers the temperature. Here, the absorbed heat may be naturally discharged into the air through the heat sink 140, but a heat dissipation pen 150 may be installed to increase the heat dissipation effect. In addition, in order to prevent external heat from being conducted to the exchanger body 110, the structure is manufactured with a heat insulating agent having excellent heat insulating performance between the enclosure 100 and the heat exchanger body 110 to minimize cooling loss. Here, the space block 110a is filled with a heat insulating material having excellent heat insulating performance in order to prevent the heat of the heat exchanger body 110 from being conducted to the heat exchanger body 110 by spacing the heat exchanger body 110 and the heat sink 140 at an appropriate distance. In addition, a method of cooling the heat exchanger body at both sides of the heat exchanger body 110 may be applied to improve the cooling performance.

FIG. 2 is a detailed view of the heat exchanger main body 110 to minimize the size of the heat exchanger main body 110 and to provide convenience of fabrication. As shown in the figure (bar), the heat exchanger main body 110 having a plurality of deep holes maximizing the surface area is extruded long and cut to an appropriate length to fit the capacity of the heat exchanger so that two deep holes are formed at both ends of the block. Attaching an end cap 400 for connecting a U-shaped grooved heat exchange conduit to form a single conduit allows the multiple seams to form a single long heat exchange conduit. .

FIG. 3 is a detailed view of the end cap 400 for connecting the heat exchange pipes attached to both ends of the block of the heat exchanger body 110 to form a U-shaped groove 400a to connect two heat exchange pipes into one pipe. Attaching to both ends of the heat exchanger body 110 can easily create a long heat exchange conduit. Here, the material of the end cap 400 for the heat exchange pipe connection may be any metal or nonmetallic material that can make a U-shaped groove.

The present invention relates to a working fluid (water, air, etc.) heat exchanger using a thermoelectric element, which can minimize the size of the heat exchanger main body and connect the long heat exchanger pipe formed inside the heat exchanger to a heat exchanger pipe having a U-shaped groove. Easily configurable with a dragon end cap makes production very easy and easy.

The heat exchanger fabricated according to the present invention is small in size (as the mass of the heat exchanger itself is small), which reduces the response time required for cooling and heating to reach the target temperature, and directly into the heat exchanger block. Not only can the working fluid temperature change with respect to the operation control of the attached thermoelectric element be made in a short time, but also because the length of the heat exchange conduit is sufficiently long, sufficient heat exchange between the heat exchanger block and the working fluid is achieved. It is possible to obtain a performance improvement.
