The present invention supplies cold and hot air using a thermoelectric module using a Peltier element, but radiates heat radiated from the Peltier element using a PCM (Phase Change Material) unit, thereby using an existing cooling fan or an accessory device for heat dissipation. The present invention relates to a noiseless cold and hot air supply device using PCM and Peltier devices that can fundamentally block noise generation and maximize heat dissipation efficiency through absorption of radiated heat of a Peltier device by the latent heat action of the PCM unit.

However, in the case of a cooling/heating device, especially a cooling/heating device using a Peltier element, there are currently no products developed when a PCM module is used as a structure to dissipate heat generated in the heating part of the Peltier element.

However, in the case of a conventional air conditioner using a Peltier element, a radiator with a plurality of fins is used to dissipate the heat generated from the heating unit, or the heat emitted from the radiator is forcibly discharged, or for cooling. There are many cases where a fan is used.

In this case, when only the radiator is used alone, since the radiating effect is inferior, various methods such as forming a plurality of fins to secure a sufficient radiating area are employed, but there are problems such as molding and manufacturing cost.

In addition, when a cooling fan is used for cooling or heat dissipation, noise or vibration is generated by the fan. Especially, when used as a home air conditioner, such noise and vibration cause a lot of inconvenience or discomfort to the user. there is a problem.

In order to explain the present invention and the operational advantages of the present invention and the object achieved by the implementation of the present invention, the following describes a preferred embodiment of the present invention and looks at it with reference.

First, terms used in the present application are only used to describe specific embodiments, and are not intended to limit the present invention, and expressions in the singular may include a plurality of expressions unless clearly different meanings in context. In addition, in the present application, terms such as "comprise" or "have" are intended to designate the presence of features, numbers, steps, actions, components, parts, or a combination thereof described in the specification, but one or more other It is to be understood that the presence or addition of features, numbers, steps, actions, components, parts, or combinations thereof, does not preclude in advance the possibility of being excluded.

In describing the present invention, when it is determined that a detailed description of a related known configuration or function may obscure the subject matter of the present invention, a detailed description thereof will be omitted.

1 to 8, the noiseless cold and hot air supply device using a PCM and a Peltier device according to the present invention includes a thermoelectric module 10 equipped with a Peltier device, a radiating body 21, and a PCM unit 23. ), a heat dissipation module comprising a first air circulation path and a second air circulation path, and a first heat transfer block enabling heat exchange between the thermoelectric module and the outflow and outflow air.

As shown in FIGS. 1 to 4, the thermoelectric module 10 according to the present invention supplies cool and warm air by using a temperature difference generated according to a current flowing through a Peltier element.

That is, in the thermoelectric module 10 according to the present invention, one conductor is connected to the upper (or lower) of the Peltier element, that is, two different materials, an n-type semiconductor and a p-type semiconductor rod, and a lower (or At the top), two conductors are disposed, each connected to each semiconductor. If the power is connected and current is passed through the two semiconductors without a temperature difference, heat moves between them according to the Peltier coefficient of each semiconductor, and heat collects on one side and the heat escapes on the other, resulting in a temperature difference at both ends.

Cold air and warmth are supplied using the cooling unit 17 and the heating unit 15 formed by the temperature difference.

To this end, the thermoelectric module 10 is provided with a box-shaped panel 11 in which a Peltier element is embedded, and a connection terminal 13 for supplying power to the Peltier element, and a power supply unit 19 is connected to the connection terminal 13. do.

In addition, as described above, in the Peltier element of the thermoelectric module 10, the positions of the cooling unit 17 and the heating unit 15 are determined according to the flow of current. In the present invention, since the heat dissipation module 20 is disposed on the top, Since the heating unit 15 of the module 10 controls the flow of current so that it can be disposed above, the cooling unit 17 is disposed below the thermoelectric module.

On the other hand, a cooling device using a Peltier element uses a radiator formed with a plurality of fins to dissipate the heat generated from the heating unit, or forcibly dissipates the radiator or radiated heat, or uses a fan for cooling. It is often used.

However, in the case of using only the heat dissipation body alone, since the heat dissipation effect is inferior, various methods such as forming a plurality of fins to secure a sufficient heat dissipation area are employed, but there are problems such as molding and manufacturing cost.

In addition, when a fan is used for cooling or heat dissipation, there is a problem that noise or vibration is generated by the fan, and especially when used as a home air conditioner, such noise and vibration cause a lot of inconvenience or discomfort to the user. there is a problem.

Therefore, in the present invention, in order to block such a problem, in particular, a noise-free cold and hot air supply device is provided through the heat dissipation module 20 in which a PCM unit filled with a phase change material is introduced to block noise, thereby eliminating discomfort or discomfort for the user .

1, 2, 8, and 9, a first heat transfer block 30 for heat exchange with a cooling unit is disposed under the thermoelectric module 10, and radiated heat of the heating unit at the top of the thermoelectric module A second heat transfer block 40 for transferring heat to the heat dissipation module is disposed. That is, the thermoelectric module 10 is disposed between the first heat transfer block 30 and the second heat transfer block 40. Here, the first and second thermal shear blocks 30 and 40 will be described later.

1, 3, 4, 8 and 9, the heat dissipation module 20 according to the present invention is disposed above the thermoelectric module 10, and has a receiving space 21a therein. It is configured to include a body 21 and a PCM unit 23 that is embedded in the receiving space 21a of the heat dissipation body 21 and disposed to be spaced apart from each other, and is filled with a phase change material therein.

First, the heat dissipation body 21 of the heat dissipation module 20 according to the present invention is made in the form of a square box, and the material is preferably made of an aluminum material advantageous for heat transfer.

More specifically, the heat dissipation body is composed of an upper plate (21A), a lower plate (21B) and a side plate (21C) (21D), and the side plate is a front plate, a rear plate, and both side plates for convenience based on the illustrations of FIGS. 3 and 4 Can be distinguished by In this case, in the illustrations of FIGS. 3 and 4, one of the side plates forming the first air circulation path is designated as one side plate 21C, and the remaining side plates, that is, the front plate, the rear plate, and another side plate. All of the plates will be determined as the other side plate 21D.

The receiving space 21a is formed in the inner space of the heat dissipation body 21 configured in this way, and the PCM unit 23 is built in a box-like shape, and the PCM unit 23 is mounted on the upper plate 21A and the lower plate 21B. Accommodating grooves (not shown) are formed at positions corresponding to each other for fixing. The PCM unit is fixed by forcibly pressing the upper end and the lower end into each receiving groove of the upper plate 21A and the lower plate 21B.

In addition, a plurality of heat dissipation fins 21b are formed on the upper plate 21A and the side plates 21C and 21D of the heat dissipation module 20, so that the second heat transfer module is in contact with the heat generating part 15 of the thermoelectric module 10. The heat transferred by the 40 and the heat generated by the heat dissipation module 20 itself are released.

In addition, the PCM unit 23 of the heat dissipation module 20 according to the present invention is made of a box-type PCM box 23a filled with a phase change material, and the PCM box 23a is made of a stainless steel material.

The PCM box (23a) is forcibly pressed into the receiving grooves of the upper plate (21A) and the lower plate (21B), and are arranged to be spaced apart from each other at regular intervals, and the thickness is preferably approximately 10 mm or less. In this case, thermal grease is applied to the upper and lower portions of the PCM box (23a) and the receiving grooves of the upper plate (21A) and lower plate (21B) of the heating body, that is, the contact surface to improve adhesion between the two components, and heat transfer. It is desirable to make this possible.

The PCM unit 23 absorbs surrounding heat through endothermic during the latent heat action of the phase change material, that is, the phase change from solid to liquid, and consumes the energy of the phase change. The heat emitted from the heating part of the thermoelectric module 10 by using the latent heat action by the phase change material is conducted to the radiating body 21 through the second heat transfer block 40, and at this time, the PCM unit 23 is latent heat. Through the action, the heat in the receiving space 21a is absorbed and radiated.

Hereinafter, the heat dissipation action through the heat dissipation body 21 and the PCM unit 23 of the heat dissipation module, and air circulation for cooling and heating through the inflow and outflow of external air will be described. However, in consideration of the convenience of explanation, the air circulation process for cooling is premised.

As shown in FIGS. 1, 3, 4, and 8, the heat dissipation module 20 according to the present invention has first and second air circulation paths 25 and 27 for circulation of air. The air circulation path 25 is configured to allow inflow and outflow of air through the heat dissipation body 21, and the second air circulation path 27 is configured to enable inflow and outflow of air through the receiving space 21a.

First, the first air circulation path 25 is formed on one side plate 21C of the radiating body so as to communicate with the first ventilation hole 25A formed in the lower plate 21B of the radiating body and the first ventilation hole 25A. It consists of a second ventilation hole (25A).

In this case, the inlet side of the first ventilation hole 25A becomes an input end, and the outlet side of the second ventilation hole 25B serves as an output end. That is, the air introduced to the input end (Inlet) absorbs heat while flowing through the heat dissipating body 21, and is heated to be discharged to the output end (Outlet). Accordingly, the radiating body 21 is radiated through heat exchange with the introduced air, and the temperature of the air discharged through the first air circulation path 25 is increased.

In this case, in order to increase the heat dissipation efficiency, the first ventilation hole 25A formed in the lower plate 21B of the heat dissipation body forms a flow path as long as possible in a zigzag shape to increase the contact time between the heat dissipation body 21 and the introduced air. It is desirable to increase the thermal efficiency.

This is a portion in which the lower plate 21B of the radiating body is in direct contact with the heat discharged from the heating unit 15 of the thermoelectric module by the second heat transfer block 40, and it is preferable to perform heat dissipation through heat exchange with external air. . Therefore, the first ventilation hole 25A formed in the lower plate 21B is preferably in a shape that can extend the flow path as much as possible in addition to the zigzag-shaped flow path.

Next, the second air circulation path 27 is formed under the other side plate 21D of the heat dissipating body, and is formed in the third ventilation hole 27A for introducing air into the receiving space 21a, and the upper plate 21A of the heat dissipating body. It is formed and consists of a fourth ventilation hole (27B) through which the air passing through the receiving space (21a) is discharged.

That is, the external air introduced into the third ventilation hole 27A as an input terminal is heated while cooling the air inside the receiving space 21a, and the air whose temperature rises through the fourth ventilation hole 27B as an output terminal Is discharged. Accordingly, the interior of the receiving space 21a of the radiating body 21 is radiated. At this time, the air flowing into the interior through the third ventilation hole 27A increases in temperature and flows to the upper portion of the receiving space 21a due to a convection phenomenon, thereby being discharged to the fourth ventilation hole 27B.

In this case, the third ventilation holes 27A are arranged in plural as shown in Fig. 4 so that air can be introduced into the space formed between the PCM boxes 23a, and external air can be directly introduced into each hole. It is also possible, but in consideration of air discharge during heating operation, it is preferable that it is formed as an outlet passage 27a connecting each hole as shown in FIG. 4.

As described above, the air discharged through the first and second air circulation paths 25 and 27 to the second and third ventilation holes 25B and 27A is directly introduced into the first thermal shear block 30 and cooled. However, in order to further increase the cooling efficiency, in the present invention, an air circulation pipe 50 is introduced between the heat dissipation module 20 and the first heat transfer block 30 to increase cooling efficiency.

For this, the air circulation pipe 50 is disposed inside the cylindrical first tube pipe 51 and the first tube pipe 51 in a stick shape as shown in FIGS. 1, 5, 8, and 9. It comprises a cylindrical second tube tube (53). In this case, a phase change material (PCM) is filled between the first tube tube 51 and the second tube tube 53, and the second tube tube 53 includes the first and second air circulation paths 25 and 27 ) Is connected and the air discharged from the first and second air circulation paths 25, 27 passes, and primary cooling is performed.

That is, the air discharged from the first and second air circulation paths 25 and 27 passes through the second tube tube 53 as air with an increased temperature, and between the first tube tube 51 and the second tube tube 53 The heat is absorbed by the phase change material (PCM) filled in and the temperature is lowered and cooled. This is that the air discharged through the first and second air circulation paths 25 and 27 is directly introduced into the first heat transfer block 30 and the air circulation pipe 50 can be primarily cooled before being cooled. The cooling efficiency can be further doubled.

In this case, in order to improve the cooling efficiency by the air circulation pipe, when the second tube pipe 53 through which air flows out is introduced in the form of a spiral pipe 53a as shown in FIG. 5B, the spiral pipe 53a The air passing through) increases the contact time with the filling PCM to enable efficient cooling.

As described above, the air that is first cooled through the air circulation pipe 50 is introduced into the first heat transfer block 30 and discharged through secondary cooling.

For this, the first heat transfer block 30 according to the present invention is disposed below the cooling unit 17 of the thermoelectric module as shown in FIGS. 1, 6, 7, 8, and 9, and transfers the first heat. Air introduced into the block 30 is cooled through heat exchange with the cooling unit 17 of the thermoelectric module.

More specifically, the first heat transfer block 30 is formed by dividing the housing 31 and the inner space of the housing 31, and is provided on one side of the air flow path 33 and the housing 31 to communicate with each other. (33), connected to the first and second air circulation paths (25) (27), and provided on the other side of the housing (31) and a plurality of first outlet holes (35) for external air It comprises a second outlet hole 37 communicating with (33) and a heat exchange plate (39) disposed on the air flow path (33).

First, the housing 31 of the first heat transfer block is made of aluminum and has a box shape, and a plurality of partition walls 31a spaced apart from each other are provided inside the housing 31. In this case, the air passages 33 are formed in the space between the partitions 31a to communicate with each other, which is communicated with each other by the outlet door 31b formed in the partitions 31a. In this case, the outflow door 31b is disposed in the opposite direction of the adjacent partitions 31a to extend the path of the air passage 33 communicating with each other as much as possible to increase the residence time of the air passing through the air passage 33 Will be ordered. In addition, it is preferable that the outflow door 31b is gradually increased in area from the inlet side to the outlet direction in order to prevent an increase in temperature due to an increase in pressure due to the amount of incoming air.

Next, the first outlet hole 35 of the first heat transfer block is formed on one side of the housing 31, that is, on the left side based on the illustration of FIG. 6, and is formed in two places. One first outlet hole 35 is introduced into the air circulation pipe 50 through the first and second air circulation paths 25, 27, and another first outlet hole 35 Allows the inflow of external air. Therefore, the circulating air and external air introduced into the first outlet hole 35 are mixed in the air passage 33, and at the same time, the air inside the air passage 33 is cooled through heat exchange with the cooling unit 17 of the thermoelectric module. I can make it.

In addition, the second outlet hole 37 of the first heat transfer block is cooled by passing through the air passage 33, and then the air introduced through the first outlet hole 35 is cooled to a place or article for receiving cooling air. Is provided.

In addition, the heat exchange plate 39 of the first heat transfer block is configured as follows to maximize the heat exchange effect between the air passing through the air flow path 33 and the cooling unit 17 of the thermoelectric module.

That is, the heat exchange plate 39 is disposed in each air flow path 33 and is composed of a bent surface 39a formed by bending in a zigzag shape, and this bent surface 39a is an air flow path 33 as shown in FIG. It is placed overlapping along the line.

In addition, a plurality of circulation holes 39b are formed in each bent surface 39a, and cooling fins 39c are formed adjacent to each circulation hole 39b and formed at a predetermined angle. In this case, the cooling fins 39c are welded to and fixed to the bent surface 39a by a brazing method.

In the heat exchange plate 39 configured as described above, the air introduced into the air flow path 33 moves through the circulation hole 39b of each bent surface 39a, and in this case, the air passing through the circulation hole 39b is a cooling fin Cooling efficiency can be further improved by (39c). That is, the cooling fin 39c acts as a resistance against the flow of air through the circulation hole 39b, thereby increasing the cooling mass of the air, which allows the air to stay in the air channel for a long time, thereby further increasing the temperature of the air. It can be lowered to increase the cooling efficiency. In this case, the cooling fins 39c are made of an aluminum plate having a thickness of 1 to 2 mm, and the bending angle is preferably maintained at approximately 30 degrees to 45 degrees.

Furthermore, since an elastomeric insulator is applied to the outer surface of the housing 31 of the first heat transfer block, the cooling efficiency can be further doubled by forming an insulating structure by blocking heat or external air.

The noiseless cold and hot air supply device using the CM and the Peltier device according to the present invention configured as described above can cool and heat. Hereinafter, a cooling circulation process and a heating circulation process will be described with reference to FIGS. 1 and 8 To

First, in the cooling circulation process, as shown in FIG. 1, external air is introduced through the input terminals (Inlets) of the first and second air circulation paths, that is, the first vent hole (25A) and the third vent hole (27A). . In this case, the external air may be compressed air, and in the case of compressed air, it may be blown through a compressor.

In this way, the air passing through the first air circulation path 25 among the air introduced into the input terminals 25A and 27A of the first and second air circulation paths lowers the temperature of the heat dissipation body 21, and the second air circulation path 27 The air passing through is heat-exchanged with the internal temperature of the heat dissipation body 21, that is, the internal temperature on the receiving space 21a to lower the temperature. The air whose temperature has risen through heat exchange while passing through the first and second air circulation paths 25 and 27 is an outlet of the first air circulation path, that is, the end of the second ventilation hole 25B and the second air circulation path. It is discharged to the output end (Outlet), that is, the fourth ventilation hole (27B).

In this case, the air whose temperature has risen discharged to the outlets of the first and second air circulation paths is not discharged to the outside, but is introduced into the air circulation pipe 50 to prevent an increase in ambient temperature.

As described above, the air introduced into the air circulation pipe 50 is first cooled and introduced into the first outlet hole 35 of the first heat transfer block, and in this case, external air is also introduced into the first outlet hole 35.

The air introduced in this way passes through the air flow path 33 of the first heat transfer block and exchanges heat with the cooling unit 17 of the thermoelectric module, and then the secondary cooled air is discharged through the second outlet hole 37 and is discharged. The cooled air is supplied to the product or place for cooling.

Next, the heating circulation process proceeds as a reverse cycle of the cooling circulation process as shown in FIG. 8, and briefly described as follows.

That is, the air introduced with external air through the second outlet hole 37 is cooled while passing through the air passage 33 of the second heat transfer block, and is introduced into the air circulation pipe 50 through the first outlet hole 35. . In this case, the cooled air is not discharged to the outside, but is directly introduced into the air circulation pipe 50 to prevent the surrounding temperature from lowering.

After that, the air introduced into the air circulation pipe 50 is firstly increased in temperature by the filling PCM. In this case, the air whose temperature has risen is directly introduced into the input terminals of the first and second air circulation paths of the heat dissipation module. In this case, the input end of the first air circulation path is an output end in the cooling circulation process, that is, the entrance of the second ventilation hole 25B, and the input end of the second air circulation path is an output in the cooling circulation process, i.e. 4 It becomes the ventilation hole (27B).

The air passing through the first air circulation path 25 among the air flowing into the first and second air circulation paths 25 and 27 is heated by heat exchange with the heating part 15 of the thermoelectric module, and the second air circulation path 27 ) Passing through is heated by heat exchange with the air in the receiving space (21a) of the heat dissipation module. The heated air is discharged to the output terminals of the first and second air circulation paths, that is, the input terminals of the first and second air circulation paths during the cooling circulation process, and is supplied to a product or place requiring heating.

The noiseless cold and hot air supply device using the PCM and Peltier device according to the present invention as described above can be used for various purposes, for example, it can be applied to a well-being bed or used as a cooling and heating device for home use.
