The pyrolytic graphite pad 20 and the metal heat dissipation plate 22 to be moved are alternately stacked.

The cooling control module 10 according to the present embodiment is mounted on various wearable devices or clothes worn on the body of a person or an animal and cools the body to increase the comfort by cooling the body.

When the weather is hot in the summer, when exercising, a lot of heat may be generated in the body when performing the work in the flame, the cooling control module 10 according to the present embodiment to cool the body to create a feeling of cool to feel cool .

Hereinafter, the cooling control module 10 according to the present embodiment will be described in detail with reference to FIGS. 1 to 3.

The thermoelectric element 12 is an electronic element manufactured using a peltier effect and has an endothermic surface 16 and a heat generating surface 14.

The Peltier effect is a phenomenon in which when two types of conductors are combined and an electric current is flowed, a temperature is raised by heating at one contact point and an endotherm is generated at the other contact point. The thermoelectric element 12 is an electronic device that generates endothermic or exothermic heat by using the Peltier effect. The thermoelectric element 12 forms a thermoelectric material made of N-type and P-type semiconductors on a ceramic substrate such as alumina (Al ₂ O ₃ ), and then an N-type thermoelectric. The general form is that the material and the P-type thermoelectric material are formed in series with the electrode. Currently, the thermoelectric element 12 is developed and manufactured in various forms, and may be manufactured in a flexible form to be applied to clothing.

In the present embodiment, the thermoelectric element 12 is not limited in shape, and in the case of applying a current, the thermoelectric element 12 includes various types of thermoelectric elements in which endotherm is generated and heat is generated on the other side.

In this embodiment, the heat absorbing surface 16 is configured to absorb heat to cool the body, and the heat generating surface 14 of the thermoelectric element 12 is provided on the heat generating surface 14 so as to easily dissipate heat. Put a heat dissipation structure. The structure of the heat dissipation structure is very important because the heat dissipation surface 14 of the thermoelectric element 12 effectively dissipates heat to efficiently cool the endothermic surface 16.

The power supply unit 24 is a component for supplying power to the thermoelectric element 12 and is connected to terminals connected to the N-type semiconductor and the P-type semiconductor of the thermoelectric element 12 to supply power. The power supply unit 24 may include a power cable 26 electrically connected to a terminal of the thermoelectric element 12, and a power battery connected to the power cable 26 to supply power.

The heat dissipation member 18 is attached to the heat generating surface 14 of the thermoelectric element 12 to dissipate heat generated from the heat generating surface 14 to the outside.

The heat dissipation member 18 according to the present invention is formed by alternately stacking a pyrolytic graphite pad 20 and a metal heat dissipation plate 22 having a predetermined thickness and moving the heat in the thickness direction. Referring to FIG. 1, a heat dissipation member 18 having a shape in which three pyrolytic graphite pads 20 and two metal heat dissipation plates 22 are alternately stacked is illustrated.

Since the cooling control module 10 is mounted on a wearable device or clothing worn on a body, the cooling control module 10 suppresses discomfort by dissipating heat to one's body or another person during a heat dissipation process, and in particular in terms of being worn on the body It is necessary to secure not only the role but also the function as the clothes to decorate the body when mounted on the clothes.

In the case of forced exhaust type through a conventional fan, hot heat radiated from the fan is directly transmitted to one's body or another person and may cause discomfort. In the case of a heat dissipation structure using a heat sink, heat dissipation performance The size of the heat sink due to the increase may increase, making it unsuitable for application to a wearable device.

Accordingly, in the present embodiment, the pyrolytic graphite pad 20 and the metal heat dissipation plate 22, which move heat in the thickness direction, are alternately stacked to form the heat dissipation member 18 so as to be suitable for the wearable cooling device with the required heat dissipation performance. It was.

Pyrolytic graphite refers to high purity graphite having high thermal conductivity and electrical conductivity. Pyrolytic graphite is a form in which hexagonal graphite structures are uniformly arranged on a two-dimensional plane, and hexagonal graphite structures on a two-dimensional plane are usually manufactured in a sheet form by laminating layers, which are pyrolytic graphite sheets. , PGS).

The pyrolytic graphite sheet is configured to rapidly spread heat on the sheet (XY plane) along the hexagonal graphite structure on the two-dimensional plane, and the movement of heat in the vertical direction of the sheet plane (XY plane), that is, the Z axis direction is large. Not considered

Therefore, in the present invention, instead of the pyrolytic graphite sheet having a very thin thickness, a pyrolytic graphite pad 20 having a predetermined thickness and moving heat in the thickness direction is applied to the exothermic surface 14. Thickness direction of the pyrolytic graphite pad 20 to be interviewed and attached (Assuming the plane of the pyrolytic graphite pad is XY plane, the thickness direction of the pyrolytic graphite pad 20 may be defined as a Z-axis direction perpendicular to the XY plane. It was configured to transfer the heat quickly to the metal heat sink (22).

In the case of the metal heat sink 22, heat is randomly diffused in the metal heat sink 22 without directivity, and the heat randomly diffused from the metal heat sink 22 is interviewed and disposed on the upper part of the metal heat sink 22. Through the pad 20, heat is moved again in the thickness direction of the Z axis with respect to the entire area.

The heat dissipation structure formed by alternately stacking the pyrolytic graphite pad 20 and the metal heat dissipation plate 22 radiates heat generated from the heat generating surface 14 of the thermoelectric element 12 in the thickness direction of the heat dissipation member 18 (Z-axis direction). By fast delivery to the outside to effectively dissipate heat to the outside of the cooling control module 10.

Looking at the heat radiation member 18 according to the present embodiment, the heat generated from the heat generating surface 14 of the thermoelectric element 12 is quickly transferred in the thickness direction (Z-axis direction) through the pyrolytic graphite pad 20, and the thickness direction The heat transferred to the substrate is randomly diffused through the metal heat sink 22 to the entire area, and is then configured to be transferred again through the pyrolytic graphite pad 20 in the thickness direction (Z-axis direction), and the outermost pyrolytic graphite pad 20 Heat transmitted in the Z-axis direction through () is emitted to the outside air through the outermost metal heat sink (in this embodiment, corresponding to the housing 28).

In the present invention, since the heat dissipation member 18 is formed by alternately stacking the pyrolytic graphite pad 20 and the metal heat dissipation plate 22 in the form of a plate, the heat dissipation member 18 can be compactly formed on a plate. According to the shape of the housing 28 surrounding the can give aesthetics to the heat dissipation member 18 is suitable for application to a wearable cooling device.

1 and 2, in the heat dissipation member 18 according to the present embodiment, the pyrolytic graphite pad 20 is first attached to the heat generating surface 14 of the thermoelectric element 12, and the metal heat dissipation plate 22 is formed. After being attached to the upper surface of the pyrolytic graphite pad 20 was configured to be alternately attached. A metal heat sink is attached to the upper surface of the uppermost pyrolytic graphite pad 20 to discharge heat generated from the heat generating surface 14 of the thermoelectric element 12 to the outside air.

FIG. 3 shows a part of the pyrolytic graphite pad 20 according to the present embodiment, wherein the heat of the heat generating surface 14 is thermally decomposed inside the silicone resin so that the heat of the pyrolytic graphite pad 20 moves in the thickness direction of the pyrolytic graphite pad 20. The form in which pyrolytic graphite is disposed as a filler 29 is shown.

Pyrolytic graphite may be manufactured in the form of a sheet in which hexagonal graphite structures are uniform on a two-dimensional plane, and heat pyrolytic graphite pads are formed inside the silicone resin 27 forming the body of the pyrolytic graphite pad 20. The pyrolytic graphite pad 20 is constituted by arranging pyrolytic graphite as the filler 29 in the thickness direction (Z-axis direction, t) so as to move in the thickness direction of 20). Since the pyrolytic graphite is arranged in the Z-axis direction, heat generated from the heat generating surface 14 of the thermoelectric element 12 can quickly move in the Z-axis direction through the pyrolytic graphite, and the silicone resin 27 forms a body. It can provide flexibility.

The thickness of the pyrolytic graphite pad 20 may be selected in the range of 1mm to 3mm. According to the experiment, when the thickness of the pyrolytic graphite pad 20 is less than 1 mm, the movement distance of heat in the Z-axis direction is short, so that heat cannot be effectively discharged in the thickness direction of the Z-axis, and when the thickness exceeds 3 mm, the pyrolytic graphite pad 20 is used. Since the heat of the lower surface takes a relatively long time to move completely to the upper surface (Z-axis direction), it also has a difficulty in discharging the heat effectively. In this embodiment, the heat dissipation member 18 was configured by using the pyrolytic graphite pad 20 having a thickness of 3 mm.

Meanwhile, the metal heat sink 22 may be made of a material including aluminum. Aluminum has a relatively high thermal conductivity and is a material commonly used as a heat sink.

The heat absorbing surface 16 of the thermoelectric element 12 is exposed. In this case, in order to further improve heat dissipation through the housing 28, the side surface of the heat dissipation member 18 is interviewed with the inner side surface of the housing 28 so that the housing 28 is at the top and side surfaces of the heat dissipation member 18. It can also be configured to exhaust heat to the outside.

The heat conduction plate 30 is interviewed on the endothermic surface 16 for transmission. The thermal conductive plate 30 is a metallic material having high thermal conductivity, and aluminum, stainless steel, or the like may be used as the thermal conductive plate 30.

In order to configure the housing 28 as part of the heat dissipation member 18, the housing 28 may be made of a material including aluminum. That is, the pyrolytic graphite pad 20 and the metal heat dissipation plate 22 are alternately stacked so that the pyrolytic graphite pad 20 is positioned at the top, thereby forming the heat dissipation member 18, and the top pyrolytic graphite pad 20 includes aluminum. It is configured to be in close contact with the inner upper surface of the housing 28 made of a material to configure the heat transferred from the top pyrolytic graphite pad 20 is discharged to the outside air through the housing 28. In addition, in order to increase heat dissipation through the housing 28, the unevenness 36 may be disposed outside the housing 28 to increase the contact surface area with the outside air.

Meanwhile, an electrical insulation sheet 32 may be interposed between the heat absorbing surface 16 of the thermoelectric element 12 and the thermal conductive plate 30. The thermoelectric element 12 is supplied with power as an electronic element. When the thermal conductive plate 30 is made of a metal material, a short circuit may occur between the thermal conductive element 12 and the thermal conductive plate 30. 32 may be disposed to prevent occurrence of a short circuit between the thermoelectric element 12 and the thermal conductive plate 30.

In addition, an insulating frame 34 may be interposed between the opening 35 of the housing 28 and the thermal conductive plate 30 along the opening 35. When the housing 28 is configured as part of the heat dissipation member 18, since heat generated in the housing 28 may be conducted to the heat conduction plate 30 that conducts cooling heat, between the housing 28 and the heat conduction plate 30. The insulating frame 34 is disposed to prevent heat transfer, thereby preventing the dissipation heat of the housing 28 or the cooling heat of the heat conduction plate 30 from moving between the housing 28 and the heat conduction plate 30.
