Description

Heat dissipation components and skin treatment devices Technical Field

[0001] This utility model relates to the field of beauty equipment technology, and in particular to a heat dissipation component and a skin treatment device. Background Technology

[0002] A hair removal device is a device used to remove body hair. Currently, home-use hair removal devices are increasingly popular due to their convenience and ease of operation. Because hair removal devices work by emitting light waves of a specific wavelength through a lamp to destroy hair follicles, the lamp generates a lot of heat during the process, which can cause a burning sensation in the treated area. Therefore, it is necessary to cool the treated area promptly to alleviate user discomfort.

[0003] Current hair removal devices mainly utilize a cooling compress to apply cold compresses to the user's skin. Therefore, timely cooling of the hair removal area is essentially cooling of the cooling compress. Related technologies propose a hair removal device including a cooling compress device, a hair removal device, a heat dissipation device, and a cooling drive device. The heat dissipation device includes a first heat dissipation component and a second heat dissipation component. The first heat dissipation component includes a first cooling plate, a first heat dissipation plate, and a first fin group. The first cooling plate and the first fin group are spaced apart and installed on the lower end face of the first heat dissipation plate. The second heat dissipation component includes a second cooling plate, a second heat dissipation plate, and a second fin group. The second cooling plate and the second fin group are spaced apart and installed on the upper end face of the second heat dissipation plate. The first cooling plate and the second cooling plate are respectively attached to the upper and lower end faces of the cooling compress device. The cooling drive device can generate an airflow towards the heat dissipation device to remove heat from the heat dissipation device.

[0004] However, the heat dissipation channels formed by the first fin group and the second fin group in the above-mentioned hair removal device are both perpendicular to the direction of the gas blowing out of the cooling device. Therefore, blockage is likely to occur at the inlet of the heat dissipation channel, affecting the heat dissipation effect of the cooling device. Summary of the Invention

[0005] The purpose of this invention is to provide a heat dissipation component and a skin treatment device to solve the problem of poor heat dissipation.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A heat dissipation assembly includes a first heat sink, a heat conductor, and a fan drive. The first heat sink includes a plurality of first fins spaced apart along a second direction, with a first heat dissipation channel extending along a first direction formed between adjacent first fins. The heat conductor is provided on both sides of the first heat sink that are opposite each other along a third direction. One end of the heat conductor is attached to the first heat sink to close one side of the opposite sides of the first heat dissipation channel along the third direction, and the other end of the heat conductor is connected to a heat source. The fan drive is disposed on one side of the first heat dissipation channel along the first direction, with the inlet of the first heat dissipation channel facing the outlet of the fan drive. The first direction is perpendicular to the second direction.

[0008] Optionally, the heat dissipation assembly further includes an air guide, which forms a first air duct and a second air duct spaced apart. The first heat dissipation component is disposed in the first air duct, and another heat source is disposed in the second air duct. The inlet of the first air duct and the inlet of the second air duct both face the air outlet of the air drive component.

[0009] Optionally, the area of ​​the air outlet of the air drive component opposite to the inlet of the first air duct is larger than the area of ​​the air outlet of the air drive component opposite to the inlet of the second air duct.

[0010] Optionally, the second air duct includes a guide section and a receiving section arranged at an angle. The receiving section is connected to the end of the guide section away from the wind drive component. The other heat source is located in the receiving section. The guide section includes an inlet section, a transition section, and a connecting section. The inlet section is located close to the wind drive component. The connecting section connects to the receiving section. The effective flow area of ​​the inlet section is smaller than the effective flow area of ​​the connecting section. The transition section connects the inlet section and the connecting section, and the effective flow area of ​​the transition section gradually increases from the end connected to the inlet section to the end connected to the connecting section.

[0011] Optionally, the air guide includes a main body and a diversion part, wherein the diversion part is disposed on one side of the main body and divides one side space of the main body into a first air duct and a second air duct.

[0012] Optionally, the diversion section includes an upper fixed frame and a lower fixed frame, which together form the second air duct.

[0013] Optionally, the heat dissipation assembly further includes a second heat dissipation component, which is located within the second air duct and is thermally connected to the other heat source.

[0014] Optionally, the second heat sink is fitted to the other heat source.

[0015] Optionally, the second heat sink includes a plurality of second fins, with adjacent second fins forming a second heat dissipation channel extending along the second direction.

[0016] A skin treatment device includes a cooling component, a cooling component, a light source assembly, and a heat dissipation assembly as described in any of the above claims. The cooling component is provided on both opposite sides of the cooling component along the third direction, and the cooling component is connected to the heat-conducting plate.

[0017] The beneficial effects of this utility model are as follows: In the heat dissipation assembly of this utility model, the inlet of the first heat dissipation channel formed by the adjacent fins on the first heat dissipation component is directed toward the air outlet of the air drive component. The airflow formed by the air drive component encounters less resistance when it blows toward the first heat dissipation component, which can dissipate the heat on the first heat dissipation component in a timely manner and improve the heat dissipation effect on the cooling component.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] Referring to Figures 1-3, an embodiment of this utility model proposes a heat dissipation component 10 and a skin treatment device. The skin treatment device includes a housing (not shown in the figures), a cooling component 20, a cooling element 50, a light source assembly 30, a control circuit board 40, and the aforementioned heat dissipation component 10. The housing has a light outlet. The cooling component 20 is embedded in the light outlet and has a contact surface for contacting human skin. The contact surface protrudes from the light outlet or is flush with the end face of the light outlet. The cooling component 20 may be, but is not limited to, made of sapphire or graphene glass. The cooling element 50 is attached to other surfaces of the cooling component 20 that are different from the contact surface. To cool the cooling compress 20, the cooling element 50 can specifically be a semiconductor cooling chip. To improve the cooling effect, cooling elements 50 are provided on both opposite sides of the cooling compress 20 along a third direction (Z direction in Figure 1). The light source assembly 30 and the heat dissipation assembly 10 are both housed inside the outer casing. The cooling compress 20, the light source assembly 30, and the heat dissipation assembly 10 are arranged sequentially at intervals along a first direction (X direction in Figure 1) at an angle to the contact surface. The contact surface is located on the side of the cooling compress 20 away from the light source assembly 30. The light source assembly 30 can emit light of a specific wavelength that passes through the light outlet of the cooling compress 20 to achieve a specific skin treatment effect. The heat dissipation assembly 10 is used to dissipate heat from the cooling element 50, which is a heat source. The control circuit board 40 connects the light source assembly 30 and the heat dissipation assembly 10 to control both. It is understood that the function of the skin treatment device varies depending on the actual needs, and therefore the wavelength of the light emitted by the light source assembly 30 will vary. For example, skin treatment devices can be used for both hair removal and skin rejuvenation, and obviously the light wavelengths used for hair removal and skin rejuvenation are different.

[0032] Referring to Figures 2 and 3, the heat dissipation assembly 10 includes a fan drive 13, a first heat sink 12, and a heat-conducting plate 11. The first heat sink 12 includes a plurality of first fins spaced apart along a second direction (Y direction in Figure 1). Adjacent first fins form a first heat dissipation channel 121 extending along a first direction. Heat-conducting plates 11 are provided on opposite sides of the first heat sink 12 along a third direction (Z direction in Figure 1). One end of the heat-conducting plate 11 is attached to the first heat sink 12 to close one side of the opposite sides of the first heat dissipation channel 121 along the third direction, and the other end is connected to the cooling component 50. The heat-conducting plate 11 is not limited to using VC sheet or graphene sheet. The fan drive 13 is located on the side of the first heat sink 12 away from the cooling component 20 along the first direction. The inlet of the first heat dissipation channel 121 faces the outlet of the fan drive 13. The first direction, the second direction, and the third direction are perpendicular to each other.

[0033] Thermal analysis shows that when the extension direction of the first heat dissipation channel 121 formed by the first heat sink 12 is perpendicular to the airflow blown out by the fan drive 13, the airflow will be blocked at the inlet of the first heat dissipation channel 121, and the lowest temperature of the cooling component 20 after cooling is 19.4℃. However, in the above-mentioned heat dissipation assembly 10, the inlet of the first heat dissipation channel 121 formed by the adjacent first fins on the first heat sink 12 is set to face the air outlet of the fan drive 13. The airflow formed by the fan drive 13 encounters less resistance when blowing towards the first heat sink 12, and can dissipate the heat on the first heat sink 12 in time. Moreover, while the heat conduction plate 11 plays a role in heat conduction, it also restricts the flow of airflow in the first heat dissipation channel 121, preventing the airflow from escaping outward when flowing through the first heat dissipation channel 121, so that the airflow can more effectively carry away the heat accumulated on the first heat sink 12. At this time, the lowest temperature of the cooling component 20 after cooling is 15.7℃, which obviously has a better cooling effect.

[0034] In addition to the cooling component 50, the light source assembly 30 is also a heat source. Therefore, to dissipate heat from the light source assembly 30, the heat dissipation assembly 10 also includes an air guide 14. The air guide 14 has a first air duct 143 and a second air duct 144 spaced apart. The first heat sink 12 is disposed in the first air duct 143, and the light source assembly 30 is disposed within the second air duct 144. The inlets of the first air duct 143 and the second air duct 144 both face the outlet of the air drive component 13. The air drive component 13 can then generate a first airflow flowing along the first air duct 143 and a second airflow flowing along the second air duct 144. The first airflow is used to dissipate heat from the first heat sink 12, and the second airflow is used to dissipate heat from the light source assembly 30.

[0035] In one embodiment, based on the premise that the cooling requirement of the cooling patch 20 takes precedence over the cooling requirement of the light source assembly 30, the area of ​​the air outlet of the wind drive component 13 relative to the inlet of the first air duct 143 is larger than the area of ​​the air outlet of the wind drive component 13 relative to the inlet of the second air duct 144, so that the amount of gas flowing to the first air duct 143 is greater than the amount of gas flowing to the second air duct 144.

[0036] Specifically, the second air duct 144 includes a guide section and a receiving section arranged at an angle. The receiving section is connected to the end of the guide section away from the wind drive component 13, and the light source assembly 30 is disposed within the receiving section. To prevent airflow blockage at the intersection of the guide section and the receiving section of the second air duct 144, the guide section of the second air duct 144 further includes an inlet section, a transition section, and a connecting section connected in sequence. The inlet section is located close to the wind drive component 13, and the connecting section is connected to the outlet of the second air duct 144. The effective flow area of ​​the inlet section is smaller than that of the connecting section. The transition section connects the inlet section and the connecting section, and its effective flow area gradually increases from the end connected to the inlet section to the end connected to the connecting section.

[0037] Referring to Figure 2, the air guide 14 includes a main body 141 and a diversion section 142. The diversion section 142 is disposed on one side of the main body 141 to divide one side of the space of the main body 141 into a first air duct 143 and a second air duct 144. Specifically, the second air duct 144 is formed within the diversion section 142. In order to reduce the difficulty of assembling the light source assembly 30 into the second air duct 144, the diversion section 142 is disposed separately, including, but not limited to, an upper fixing frame 1421 and a lower fixing frame 1422 connected by bolts or snaps. The lower fixing frame 1422 is fixedly disposed on the main body 141, and the upper fixing frame 1421 and the upper fixing frame 1421 together form the second air duct 144. As for the main body 141, in order to make reasonable use of the space inside the housing and reduce the volume of the skin treatment device, the control circuit board 40 can be used as the main body 141. The electronic components and circuits on the control circuit board 40 are disposed on the side facing away from the lower fixing frame 1422. Of course, a separate thin plate-like structure was also set up as the main body 141.

[0038] In one embodiment, the upper fixing frame 1421 and the lower fixing frame 1422 together form a mounting cavity for mounting the cold compress 20. The mounting cavity has an outlet through which the cold compress 20 passes, and the contact surface of the cold compress 20 passes through the outlet into the mounting cavity.

[0039] Referring to Figure 2, the light source assembly 30 includes a light-emitting element 31, a filter element 32, and a reflector element 33. The filter element 32 is disposed between the light-emitting element 31 and the cooling device 20 to filter the light emitted by the light-emitting element 31, thereby forming light with a specific wavelength. Specifically, the filter element 32 divides the inner cavity formed by the upper fixing frame 1421 and the lower fixing frame 1422 into a second air duct 144 and an installation cavity to prevent the air used to cool the light source assembly 30 from blowing towards the cooling device 20 and affecting the cooling effect of the cooling device 20. The reflector element 33 is disposed on the side of the light-emitting element 31 facing away from the filter element 32 to reflect the light emitted by the light-emitting element 31 onto the filter element 32, thereby improving the light extraction efficiency. Specifically, the reflector element 33 adopts a reflector cup with an arc-shaped cross-section, and the light-emitting element 31 adopts an IPL lamp tube. The IPL lamp tube extends along a second direction, and the light-emitting element 31 has through holes at both ends along the second direction for the IPL lamp tube to pass through.

[0040] To improve the heat dissipation effect of the light-emitting element 31 in the light source assembly 30, the heat dissipation assembly 10 further includes a second heat dissipation element 15 that is thermally connected to the light source assembly 30. The second heat dissipation element 15 is located within the second air duct 144 and includes multiple second fins. A second heat dissipation channel 151 is formed between adjacent second fins. To make reasonable use of space, the multiple second fins are spaced apart along a third direction, and the second fins extend along a second direction, that is, the second heat dissipation channel 151 extends along the second direction. The second heat dissipation element 15 also includes an arc-shaped heat dissipation plate that conforms to the reflector 33. The arc-shaped heat dissipation plate is attached to the reflector 33 to achieve a thermally conductive connection with the reflector 33. The multiple second fins are disposed on the side of the arc-shaped heat dissipation plate facing away from the reflector 33. For example, both the first heat dissipation element 12 and the second heat dissipation element 15 are made of aluminum, which is lightweight and has high structural strength.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
