However, according to the cold and cold storage according to the prior art as described above, the thermoelectric module 3 may act to raise or lower the temperature rapidly, but only the block that is the first heat transfer member 4, the inner case 21 There was a problem in that it is inadequate to transfer the heat of the low temperature or high temperature into the interior of the cold and can not perform the cold function smoothly.

The present invention was created to solve the above problems, and transfers the heat emitted from the thermoelectric module to the inner case without loss to perform the warmer function smoothly and the thermoelectric module absorbs heat in the inner case without loss It is an object of the present invention to provide a cold and cold vehicle for the vehicle using a thermoelectric module that can be discharged to the outside to perform the refrigerator function smoothly.

The present invention for achieving the above object, the cold and cold case consisting of an outer case is formed on one side and the inner case for receiving the contents, and the outer case surrounding it to form a sealing space between the inner case; A door for opening and closing the opening of the inner case; A heat transfer block embedded between the outer case and the inner case; It is fixedly installed on the outer surface of the outer case corresponding to the heat transfer block, and absorbs heat to one side corresponding to the heat transfer block according to the flow direction of the current and heat radiation to the other side, or radiate heat to one side corresponding to the heat transfer block And a thermoelectric module for absorbing heat to the other side; One end is connected to the heat transfer block, and the other end is installed to surround the outer surface of the inner case and a plurality of heat transfer pipes of a predetermined length are installed to be in close contact with the inner case.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the cold and cold storage for vehicles according to the present invention will be described in detail.

Figure 2 is a view showing the configuration of a thermoelectric module applied to the present invention, Figure 3 is an external perspective view of the cold and cold storage according to the present invention, a perspective view showing the inner case, Figure 4 is It is sectional drawing which shows the structure of cold and cold storage.

As shown in the drawing, the present invention includes a cold / cold storage case 10, a door 15, a thermoelectric module 13, a heat transfer block 14, and a heat transfer pipe 20.

The cold / cold storage case 10 has an opening 11a formed at one side and an inner case 11 for storing or storing contents and a sealing space S between the inner case 11. It consists of an outer casing 12 that surrounds it.

The door 15 opens and closes the opening part 11a of the inner case 11.

The heat transfer block 14 is made of an aluminum material excellent in heat transfer, is built between the outer case 12 and the inner case 11 to perform a heat transfer function.

The thermoelectric module 13 is fixedly installed on an outer surface of the outer case 12 corresponding to the heat transfer block 14, and absorbs heat toward one side corresponding to the heat transfer block 14 according to a current flow direction. In addition, it is configured to radiate heat to the other side or radiate heat to one side corresponding to the heat transfer block 14 and to absorb heat to the other side.

The thermoelectric module 13 may have various configurations, but as an example, as illustrated in FIGS. 2A and 2B, semiconductor thermoelectric devices including N-type semiconductor devices and P-type semiconductor devices may be used. Alternatingly arranged and alternately connected to the upper metal electrode 32 and the lower metal electrode 34 through the upper and lower surfaces of the thermoelectric semiconductor elements, so that all the semiconductor elements 33 are electrically connected in series. The connection between the upper and lower metal electrodes 32, 34 and the thermoelectric semiconductor element is made by soldering. Metal electrodes 32 and 34 at the upper and lower surfaces of the isoconductor are connected on the metallized ceramic substrates 31 and 35, respectively, to hold the entire assembly together. The DC power supply is connected to the electrodes of this thermoelectric element. As a result, when current flows from each N-type semiconductor element to the P-type semiconductor element, heat is absorbed at the top and radiated through the bottom due to the Peltier effect.

In other words, as shown in Fig. 2A, the upper portion of each NP type semiconductor thermoelectric element acts as an absorption cooling junction CJ, and the lower portion connected to the PN type acts as a radiator heating junction HJ. By changing the polarity of the power supply, it is possible to change the direction in which heat is absorbed and released.

The heat transfer pipe 20 has one end connected to the heat transfer block 14 and installed to surround the outer surface of the inner case 11, including a portion extending from the one end to the other end and the other end, and an inner case. It is in close contact with (11).

Here, by installing a plurality of the heat transfer pipe 20 to more effectively perform the mutual heat transfer function between the inner case 11 and the heat transfer block (14).

In the present invention, in order to further increase the mutual heat transfer efficiency between the inner case 11 and the heat transfer block 14, a portion of the outer surface of the heat transfer pipe 20 is buried on the outer surface of the inner case 11 so that the inner case ( The recessed groove 11b was formed in the outer surface of 11).

That is, as the concave groove 11b is formed, the thickness of the inner case 11 of the portion where the concave groove 11b is formed is different from the thickness of the inner case 11 where the concave groove 11b is not formed. The thin part is good for heat transfer. That is, the heat transfer from the heat transfer pipe 20 side to the inner case 11 side or from the inner case 11 side to the heat transfer pipe 20 side is good.

Here, in order to increase the heat transfer area in contact with the inner case 11 of the outer surface of the heat transfer pipe 20 may be carried out in a variety of changes, such as rectangular, slot shape, streamline shape.

On the other hand, the present invention, as shown in Figure 4, by forming a recess groove 14a on the outer surface of the heat transfer block 14 corresponding to the recess groove 11b formed on the outer surface of the inner case 11, It may be configured to surround the outer surface of the heat transfer pipe 20 by the matching of the recessed groove (11b) 14a.

By forming the concave grooves 11b and 14a corresponding to each other in the inner case 11 and the heat transfer block 14 as described above, the heat transfer pipe 20 is formed by the inner surface of the concave grooves 11b and 14a. By enclosing the outer surface, the heat transfer performance can be improved more effectively.

Reference numeral 16 is a heat sink that transfers heat to the outside of the thermoelectric module 13, and in the present invention, the cooling fan 6 is forced to cool the surrounding heat adjacent to the heat sink 16 as in the prior art. ) Is installed more independently.

Referring to the operation of the cold and hot refrigerator according to the present invention configured as described above are as follows.

First, as shown in FIG. 2A, when the power source is connected to the thermoelectric element module to absorb heat from the ceramic substrate 31 and operate to release heat through the ceramic substrate 35, the ceramic substrate 35 is operated. Heat released at is transferred through the heat transfer block 14 in contact therewith.

Thereafter, the heat transferred through the heat transfer block 14 is transferred to the inner case 11 through the plurality of heat transfer pipes 20, thereby performing a warmer function that warms the contents contained in the inner case 11. .

Herein, the heat transfer pipe 20 may be used as long as it is a metal material capable of heat transfer. In the present invention, the heat transfer pipe 20 is hermetically sealed to have a vacuum space therein and a tube having a working fluid therein.

According to the configuration of the heat transfer pipe 20 as described above, the working fluid is heated by the high temperature heat source transmitted from the heat transfer block 14 and then evaporated, and condensed while moving toward the end of the heat transfer pipe 20. After the heat is discharged to the (11) side, the process of returning to the end side of the heat transfer pipe 20 adjacent to the high temperature side of the heat transfer block 14 again by riding on the inner wall surface of the heat transfer pipe 20 is repeated. The high temperature heat transferred to the block 14 is transferred to the inner case 11, which makes it possible to utilize the inner case 11 as a warmer.

Meanwhile, when the polarity of the power source connected to the thermoelectric semiconductor is changed, heat is absorbed from the ceramic substrate 35 to release heat to the outside through the ceramic substrate 31.

The heat in the inner case 11 is transferred to the heat transfer block 14 through the plurality of heat transfer pipes 20 by the action of the heat transfer conductors, and then, the heat transferred to the heat transfer block 14 is transferred to the ceramic substrate ( The heat absorbed by the heat absorber 35 to release heat to the outside through the ceramic substrate 31 causes the temperature in the inner case 11 to be lower than that of the first, thereby allowing the refrigerator to function freshly.

In more detail, since the portion corresponding to the heat transfer block 14 of one side of the thermoelectric module 13 has an endothermic effect, the temperature at the end of the heat transfer block 14 in both ends of the heat transfer pipe 20 is It is relatively higher than the temperature of the end adjacent to the heat transfer block 14.

Therefore, the working fluid in the heat transfer pipe 20 evaporates and condenses as it moves from the end side away from the heat transfer block 14, and dissipates heat at the end side of the heat transfer pipe 20 adjacent to the heat transfer block 14. Next, the process of returning the inner wall surface of the heat transfer pipe 20 toward the end of the heat transfer pipe 20 far from the heat transfer block 14 is repeated.

In this process, the heat discharged from the end side of the heat transfer pipe 20 adjacent to the heat transfer block 14 is absorbed by the thermoelectric module 13 via the heat transfer block 14.

As a result, the temperature in the inner case 11 is gradually lowered to perform the refrigerator function.

On the other hand, although the present invention is not shown in the drawings, in the above-described embodiment, the thermoelectric module 13 and the thermoelectric element 13 to maintain the freshness more effectively with respect to the storage stored in the inner case 11 and at a high temperature state It is preferable to install the heat transfer block 14 on the inner wall of the inner case 11 corresponding to a position where the contents contained in the inner wall of the inner case 11 are in close contact with each other by their own weight.

In addition, the heat transfer pipe 20 is preferably installed so as to extend from the point of the inner case 11 in which the thermoelectric module 13 and the heat transfer block 14 are installed.

As described above, according to the cold and cold cabinet using the thermoelectric semiconductor according to the present invention, by transferring the heat emitted from the thermoelectric semiconductor to the inner case without loss to perform the warmer function smoothly and the thermoelectric semiconductor endothermic without loss of the inner case Emitted to the outside can perform the refrigerator function smoothly.
