Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to a heat dissipation component and an oil heater. Background Technology

[0002] Currently, the surface temperature of oil-filled radiators in related technologies is relatively high. In order to reduce the surface temperature, the heat dissipation effect is usually improved by increasing the number of heat sinks in the oil-filled radiator. However, this increases the overall size, making the entire oil-filled radiator bulky and expensive. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, a first aspect of the present invention provides a heat dissipation component.

[0005] A second aspect of the present invention also provides an oil heater.

[0006] In view of this, a first aspect of the present invention provides a heat dissipation assembly, comprising: a plurality of heat sinks connected in sequence, each heat sink comprising: a body, the bodies of the plurality of heat sinks being connected in sequence; and fins disposed on the sidewall of the body along the distribution direction of the plurality of heat sinks.

[0007] The heat dissipation assembly provided by the present invention includes a plurality of heat sinks connected in sequence. Each heat sink includes a body and fins. The bodies are connected in sequence, and airflow flows between two adjacent bodies to carry away the heat of the heat sink and cool it down. At the same time, along the distribution direction of the plurality of heat sinks, the fins are disposed on the side wall of the body, that is, the fins are located between two adjacent bodies. Without increasing the volume, the fins effectively increase the heat dissipation area of ​​the heat dissipation assembly and improve the heat dissipation effect.

[0008] The heat dissipation assembly provided by the present invention may further have the following additional technical features:

[0009] In the above technical solution, the fins of multiple heat sinks are further arranged on the same side of the corresponding body.

[0010] In this technical solution, the fins of multiple heat sinks are arranged on the same side of the corresponding body, so that fins are provided between adjacent bodies. This increases the heat exchange area and improves the heat dissipation effect, while also making the heat dissipation more uniform.

[0011] In any of the above technical solutions, further, the number of fins on any body is at least two, and the at least two fins are located on the same side of the body; in two adjacent bodies, at least two fins on one body surround the cavity with the two bodies, wherein, along the distribution direction of the multiple heat sinks, at least one fin has a gap with the other body.

[0012] In this technical solution, each body has at least two fins, which are arranged on the same side of the body, such that the at least two fins and the opposing walls of the two bodies together define a cavity. Since there is a gap between at least one fin and the other body, the cavity is semi-enclosed. On the one hand, the semi-enclosed cavity has a chimney effect; guided by the cavity, the heat dissipated between adjacent bodies can form a thermal convection effect within the cavity, causing heat to flow upwards at a relatively fast speed. That is, the high-temperature airflow within the semi-enclosed cavity convections with the low-temperature airflow at the bottom, accelerating the dissipation of heat into the air. On the other hand, the gap between the fins and adjacent bodies allows cold air to flow into the semi-enclosed cavity through the gap and exchange heat with the fins and bodies, thereby continuously forming thermal convection, accelerating heat dissipation, and reducing the surface temperature of the heat sink.

[0013] In any of the above technical solutions, the body is further provided with a flange structure, which surrounds at least part of the periphery of the body.

[0014] In this technical solution, the main body is provided with a flanged structure. By setting the flanged structure, the heat exchange area is increased without increasing the overall volume. Specifically, the flanged structure surrounds at least part of the periphery of the main body, thereby increasing the area of ​​the flanged structure, which in turn increases the heat exchange area and improves the heat dissipation efficiency of the heat dissipation component.

[0015] In any of the above technical solutions, the flange structure is further bent toward the wall surface where the fin is located, or the flange structure is bent toward the body away from the wall surface where the fin is located.

[0016] In this technical solution, along the distribution direction of multiple heat sinks, the flange structure is bent towards the side where the fins are located, or the flange structure is bent towards the side of the body away from the wall where the fins are located, so that the flange structure can cover a larger space, thereby increasing the heat dissipation area of ​​the flange structure and improving the heat dissipation effect of the heat dissipation component.

[0017] In any of the above technical solutions, the flange structure further includes: a first bending portion, which extends from the body in a direction away from the wall surface where the fin is located; and a second bending portion, which is connected to the first bending portion and extends from the first bending portion towards the wall surface where the fin is located.

[0018] In this technical solution, the flanged structure includes a first bend and a second bend. The first bend extends from the main body in a direction away from the wall surface where the fins are located. Specifically, the first bend is inclined relative to the wall surface where the fins are located, which increases the heat exchange area and facilitates the guidance of airflow, allowing the flanged structure to fully exchange heat with the airflow and reducing the surface temperature of the heat sink. The second bend extends from the first bend towards the wall surface where the fins are located, thereby effectively increasing the heat exchange area while maintaining the overall volume.

[0019] In any of the above technical solutions, the flange structure further includes a third bending portion, which is connected to the second bending portion, and the third bending portion is bent from the second bending portion toward the direction close to the fin.

[0020] In this technical solution, the flange structure also includes a third bending section, which bends inward from the second bending section, further increasing the heat exchange area.

[0021] In any of the above technical solutions, the body is further provided with through holes, which penetrate the body along the distribution direction of the multiple heat sinks.

[0022] In this technical solution, the main body is also provided with through holes, which penetrate the main body along the distribution direction of multiple heat sinks. By setting the through holes, airflow can flow through the through holes along the distribution direction of multiple heat sinks, thereby enhancing the airflow convection effect.

[0023] In any of the above technical solutions, further, each body is provided with two oil guiding cavities, and the body is provided with an oil passage communicating with the two oil guiding cavities. Multiple heat sinks are connected through the two oil guiding cavities. Along the line connecting the centers of the two oil guiding cavities, the fins are located between the centers of the two oil guiding cavities.

[0024] In this technical solution, each body is provided with two oil guiding chambers, and the body is provided with an oil passage that communicates with the two oil guiding chambers. Multiple heat sinks are connected through the oil guiding chambers, thereby heating the oil in the oil guiding chambers to achieve heat transfer. The fins are located between the centers of the two oil guiding chambers, that is, the height of the fins does not exceed the center of the oil guiding chamber, ensuring the distance between the fins and the upper end of the body, and the distance between the fins and the lower end of the body, so that the cold air at the bottom has enough space to enter the cavity, and the top also has enough space for the airflow to flow out.

[0025] In any of the above technical solutions, the oil passage further includes: a first oil passage, which is connected to two oil guide chambers and extends along the line connecting the centers of the two oil guide chambers; and a second oil passage, which is connected to the first oil passage and is symmetrically arranged on both sides of the first oil passage along the line connecting the centers of the two oil guide chambers; wherein, there are multiple second oil passages, which are distributed along the line connecting the centers of the two oil guide chambers.

[0026] In this technical solution, the oil passage includes a first oil passage and a second oil passage. The first oil passage extends along the line connecting the centers of the two oil guide cavities on the same body, thereby transferring heat from the bottom to the top of the body through the first oil passage. The second oil passage is symmetrically arranged on both sides of the first oil passage, so that the heat is dispersed from the first oil passage to the second oil passage on both sides, and then transferred to the flange structure and fins, realizing heat diversion and improving the heat dissipation effect.

[0027] In any of the above technical solutions, further, along the distribution direction of the multiple heat sinks, the distance between the walls on the same side of two adjacent bodies is greater than or equal to 25mm and less than or equal to 35mm.

[0028] In this technical solution, along the distribution direction of multiple heat sinks, the distance between the walls on the same side of two adjacent bodies is between 25mm and 35mm. By reducing the spacing between adjacent bodies, the overall volume of the heat dissipation component is reduced, and it is easier to form a significant thermal difference between adjacent bodies, thereby accelerating the formation of the chimney effect.

[0029] According to a second aspect of the present invention, an oil-filled radiator is also provided, comprising: a heat dissipation component as described in any of the above-described technical solutions.

[0030] The oil heater provided in the second aspect of the present invention, because it includes the heat dissipation component proposed in any of the above-mentioned technical solutions, has all the beneficial effects of the heat dissipation component.

[0048] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0049] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0050] The following reference Figures 1 to 13 The present invention describes a heat dissipation assembly 100 and an oil heater according to some embodiments thereof.

[0051] Example 1:

[0052] like Figure 1 and Figure 2 As shown, according to an embodiment of the first aspect of the present invention, the present invention provides a heat dissipation assembly 100, comprising: a plurality of heat sinks 102, each heat sink 102 comprising: a body 104 and fins 106.

[0053] Specifically, multiple heat sinks 102 are connected in sequence, and the bodies 104 of the multiple heat sinks 102 are connected in sequence; along the distribution direction of the multiple heat sinks 102, fins 106 are disposed on the side wall of the body 104.

[0054] The heat dissipation assembly 100 provided by the present invention includes a plurality of heat sinks 102 connected in sequence. Each heat sink 102 includes a body 104 and fins 106. The bodies 104 are connected in sequence, and airflow flows between two adjacent bodies 104 to carry away the heat of the heat sink 102, thereby cooling the heat sink 102. At the same time, along the distribution direction of the plurality of heat sinks 102, the fins 106 are disposed on the side wall of the body 104, that is, the fins 106 are located between two adjacent bodies 104. Without increasing the volume, the arrangement of the fins 106 effectively increases the heat dissipation area of ​​the heat dissipation assembly 100 and improves the heat dissipation effect.

[0055] Specifically, such as Figure 1 and Figure 2 As shown, arrow A indicates the distribution direction of multiple heat sinks 102, arrow B indicates the width direction of the body 104, and arrow C indicates the height direction of the body 104, which is also the direction of the line connecting the centers of the two oil guide cavities 114 on the same body 104.

[0056] Specifically, the fins 106 extend along the C direction. The fins 106 on each body 104 are disposed on the side wall of the body 104, and in multiple bodies 104, the fins 106 can be disposed on different side walls of the body 104.

[0057] Example 2:

[0058] like Figure 1 , Figure 8 and Figure 9 As shown, according to one embodiment of the present invention, including the features defined in the above embodiments, and further: the fins 106 of the plurality of heat sinks 102 are all disposed on the same side of the corresponding body 104.

[0059] In this embodiment, the fins 106 of the multiple heat sinks 102 are arranged on the same side of the corresponding body 104, so that fins 106 are provided between adjacent bodies 104. This increases the heat exchange area and improves the heat dissipation effect, while also making the heat dissipation more uniform.

[0060] Furthermore, such as Figure 2 , Figure 3 and Figure 8 As shown, the number of fins 106 on any body 104 is at least two, and the at least two fins 106 are located on the same side of the body 104; in two adjacent bodies 104, at least two fins 106 on one body 104 and the two bodies 104 enclose a cavity 108, wherein, along the distribution direction of the plurality of heat sinks 102, at least one fin 106 has a gap with the other body 104.

[0061] In this embodiment, the number of fins 106 on any one body 104 is at least two, and the at least two fins 106 are disposed on the same side of the body 104, such that the at least two fins 106 and the opposing walls of the two bodies 104 together enclose the cavity 108. Meanwhile, as... Figure 8 As shown, along the distribution direction of the multiple heat sinks 102, that is, along direction A, there is a gap between at least one fin 106 and another body 104. Therefore, the cavity 108 is a semi-enclosed cavity 108. On the one hand, the semi-enclosed cavity 108 has a chimney effect. Under the guidance of the cavity 108, the heat dissipated between two adjacent bodies 104 can form a thermal convection effect in the cavity 108, so that the heat flows upward in the cavity 108 at a relatively fast speed. That is, the high-temperature airflow in the semi-enclosed cavity 108 and the low-temperature airflow at the bottom generate convection, accelerating the dissipation of heat into the air. On the other hand, there is a gap between the fin 106 and the adjacent body 104, so that cold air can flow into the semi-enclosed cavity 108 through the gap and exchange heat with the fin 106 and the body 104, thereby continuously forming thermal convection, accelerating the dissipation of heat, and reducing the surface temperature of the heat sink 102.

[0062] Specifically, such as Figure 1 and Figure 2 As shown, at least two fins 106 are spaced apart along the width direction of the body 104, that is, along the B direction.

[0063] Specifically, there are two fins 106 on the body 104, and the two fins 106 are spaced apart along the width direction of the body 104. In two adjacent bodies 104, the two fins 106 located between the two bodies 104 enclose a cavity 108 with a portion of the two wall surfaces opposite to the two bodies 104. The two fins 106 are disposed on one body 104, and at least one of the two fins 106 has a gap with the other body 104.

[0064] Specifically, the main body 104 is provided with an oil passage 116 and two oil guide chambers 114 connected to the oil passage 116. Two fins 106 on the same main body 104 are located on both sides of the oil passage 116, so that the two fins 106 surround the oil passage 116, so that a high temperature hot airflow is formed inside, and the heat convection effect is enhanced.

[0065] Example 3:

[0066] like Figure 4 and Figure 5 As shown, according to one embodiment of the present invention, including the features defined in any of the above embodiments, and further: the body 104 is also provided with a flange structure 110, the flange structure 110 surrounding at least a portion of the periphery of the body 104.

[0067] In this embodiment, the body 104 is provided with a flange structure 110. By providing the flange structure 110, the heat exchange area is increased without increasing the overall volume. The flange structure 110 surrounds at least part of the periphery of the body 104, thereby increasing the area of ​​the flange structure 110, that is, increasing the heat exchange area, and thus improving the heat dissipation efficiency of the heat dissipation component 100.

[0068] Specifically, the flange structure 110 is arranged around part of the periphery of the body 104, that is, a part of the periphery of the body 104 is not provided with the flange structure 110, so that the airflow can enter the space enclosed by the flange structure 110 through the part without the flange structure 110, exchange heat with the flange structure 110, enhance the convection efficiency of the airflow, and improve the heat dissipation effect.

[0069] Furthermore, along the distribution direction of the multiple heat sinks 102, the flange structure 110 is projected onto a plane perpendicular to the distribution direction of the multiple heat sinks 102. Within the resulting projection plane, the flange structure 110 is U-shaped.

[0070] Furthermore, the flange structure 110 is bent toward the wall surface where the fin 106 is located, or the flange structure 110 is bent toward the body 104 away from the wall surface where the fin 106 is located.

[0071] In this embodiment, along the distribution direction of the multiple heat sinks 102, the flange structure 110 is bent toward the side where the fins 106 are located, or the flange structure 110 is bent toward the wall of the body 104 away from the wall where the fins 106 are located, so that the flange structure 110 can cover a larger space, thereby increasing the heat dissipation area of ​​the flange structure 110 and improving the heat dissipation effect of the heat dissipation component 100.

[0072] Furthermore, the flanged structures 110 on multiple bodies 104 are all bent to the same side, thereby making the heat dissipation of each part of the heat dissipation assembly 100 more uniform.

[0073] Furthermore, such as Figure 4 As shown, the flange structure 110 includes: a first bending portion 1100, which extends from the body 104 in a direction away from the wall surface where the fin 106 is located; and a second bending portion 1102, which is connected to the first bending portion 1100 and extends from the first bending portion 1100 to the wall surface where the fin 106 is located.

[0074] In this embodiment, the flanged structure 110 includes a first bending portion 1100 and a second bending portion 1102. The first bending portion 1100 extends from the body 104 in a direction away from the wall surface where the fins 106 are located. Specifically, the first bending portion 1100 is inclined relative to the wall surface where the fins 106 are located. This increases the heat exchange area and also facilitates the guidance of airflow, allowing the flanged structure 110 to fully exchange heat with the airflow and reduce the surface temperature of the heat sink 102. The second bending portion 1102 extends from the first bending portion 1100 in a direction towards the wall surface where the fins 106 are located, thereby effectively increasing the heat exchange area while maintaining the overall volume.

[0075] Furthermore, such as Figure 4 As shown, the flange structure 110 further includes a third bending portion 1104, which is connected to the second bending portion 1102, and the third bending portion 1104 is bent from the second bending portion 1102 toward the direction close to the fin 106.

[0076] In this embodiment, the flange structure 110 further includes a third bending portion 1104, which bends inward from the second bending portion 1102, further increasing the heat exchange area.

[0077] Example 4:

[0078] like Figure 3 , Figure 12 and Figure 13 As shown, according to one embodiment of the present invention, including the features defined in any of the above embodiments, and further: the body 104 is also provided with a through hole 112, which penetrates the body 104 along the distribution direction of the plurality of heat sinks 102.

[0079] In this embodiment, the body 104 is also provided with a through hole 112. The through hole 112 penetrates the body 104 along the distribution direction of the multiple heat sinks 102. By setting the through hole 112, airflow can flow through the through hole 112 along the distribution direction of the multiple heat sinks 102, thereby enhancing the convection effect of the airflow.

[0080] Specifically, such as Figure 3 As shown, a through hole 112 is provided between the fin 106 and the flange structure 110. The through hole 112 between the fin 106 and the flange structure 110 increases the thermal resistance between the two, thereby enabling heat to be autonomously distributed to the fin 106 and the flange structure 110, achieving efficient thermal balance.

[0081] Example 5:

[0082] like Figure 6 , Figure 7 and Figure 10 As shown, according to one embodiment of the present invention, including the features defined in any of the above embodiments, and further: each body 104 is provided with two oil guiding cavities 114, and the body 104 is provided with an oil passage 116 communicating with the two oil guiding cavities 114, and a plurality of heat sinks 102 are connected through the two oil guiding cavities 114; along the line direction connecting the centers of the two oil guiding cavities 114, the fins 106 are located between the centers of the two oil guiding cavities 114.

[0083] In this embodiment, each body 104 is provided with two oil guiding chambers 114, and the body 104 is provided with an oil passage 116 communicating with the two oil guiding chambers 114. Multiple heat sinks 102 are connected through the oil guiding chambers 114, thereby transferring heat by heating the oil in the oil guiding chambers 114. The fins 106 are located between the centers of the two oil guiding chambers 114, that is, the height of the fins 106 does not exceed the center of the oil guiding chambers 114, ensuring the distance between the fins 106 and the upper end of the body 104, and the distance between the fins 106 and the lower end of the body 104, so that the cold air at the bottom has enough space to enter the cavity 108, and the top also has enough space for the airflow to flow out.

[0084] Furthermore, such as Figure 2 and Figure 3 As shown, two oil guiding cavities 114 are distributed along the length direction C of the body 104, and heating elements are provided in the oil guiding cavities 114. Figure 10 As shown, the length direction of the fin 106 is arranged along the line connecting the centers of the two oil guide cavities 114 on the same body 104.

[0085] Specifically, along the line connecting the centers of the two oil guide cavities 114 on the same body 104, that is, along the length direction C of the body 104, the length X of the fin 106 is less than or equal to the distance between the two oil guide cavities 114.

[0086] Example 6:

[0087] like Figure 2 , Figure 12 and Figure 13 As shown, according to an embodiment of the present invention, including the features defined in any of the above embodiments, and further: the oil passage 116 includes: a first oil passage 1160, communicating with two oil guide chambers 114, and the first oil passage 1160 extends along the line connecting the centers of the two oil guide chambers 114; a second oil passage 1162, communicating with the first oil passage 1160, and symmetrically arranged on both sides of the first oil passage 1160 along the line connecting the centers of the two oil guide chambers 114; wherein, there are multiple second oil passages 1162, and the multiple second oil passages 1162 are distributed along the line connecting the centers of the two oil guide chambers 114.

[0088] In this embodiment, the oil passage 116 includes a first oil passage 1160 and a second oil passage 1162. The first oil passage 1160 extends along the line connecting the centers of the two oil guide cavities 114 on the same body 104, that is, it extends in direction C, so that heat is transferred from the bottom of the body 104 to the top of the body 104 through the first oil passage 1160. The second oil passage 1162 is symmetrically arranged on both sides of the first oil passage 1160, so that heat is dispersed from the first oil passage 1160 to the second oil passages 1162 on both sides, and then transferred to the flange structure 110 and the fins 106, thereby realizing heat diversion and improving the heat dissipation effect.

[0089] Specifically, guide holes are provided on the body 104, thereby forming a first oil passage 1160 and a second oil passage 1162 on the body 104. That is, guide holes are provided between two adjacent pairs of second oil passages 1162, thereby realizing the diversion of heat.

[0090] Specifically, along the line connecting the centers of the two oil guide cavities 114 of the same body 104, the second oil passage 1162 can also be staggered and arranged on both sides of the first oil passage 1160.

[0091] Example 7:

[0092] like Figure 8 and Figure 11 As shown, according to one embodiment of the present invention, including the features defined in any of the above embodiments, and further: along the distribution direction of the plurality of heat sinks 102, the distance L between the walls on the same side of two adjacent bodies 104 is greater than or equal to 25 mm and less than or equal to 35 mm.

[0093] In this embodiment, along the distribution direction of the plurality of heat sinks 102, the distance L between the walls on the same side of two adjacent bodies 104 is between 25mm and 35mm. By reducing the spacing between adjacent bodies 104, the overall volume of the heat dissipation assembly 100 is reduced, and it is easier to form a significant thermal difference between adjacent bodies 104, thereby accelerating the formation of the chimney effect.

[0094] Example 8:

[0095] According to a second aspect of the invention, an oil-filled radiator is also provided, comprising: a heat dissipation assembly 100 as described in any of the above embodiments.

[0096] The oil heater provided in the second aspect of the present invention, since it includes the heat dissipation component 100 proposed in any of the above embodiments, has all the beneficial effects of the heat dissipation component 100.

[0097] Specifically, the oil heater has a heating element, which is disposed in the oil guide cavity 114.

[0098] Example 9:

[0099] like Figures 1 to 13 As shown, according to a specific embodiment of the present invention, the heat dissipation assembly 100 includes a plurality of heat sinks 102. Each heat sink 102 includes a body 104 and fins 106. The periphery of the body 104 is provided with a flange structure 110, and the sidewall of the body 104 is provided with fins 106. The sidewall of the body 104 is any wall surface along the distribution direction of the plurality of heat sinks 102. In this way, after the heat is heated by the heat-conducting oil circulation in the oil passage 116, it diffuses to the body 104. When it reaches the edge of the body 104, it is pre-heated by the fins 106 and forms a heat flow inside the cavity 108. The heat is accelerated to be dissipated into the air through the chimney effect. After the heat is diverted by the fins 106, the remaining heat diffuses to the flange structure 110. Through the large heat dissipation surface of the flange structure 110, it fully contacts the external cold air to dissipate heat, which not only reduces the surface temperature of the heat dissipation assembly 100, but also improves the heating effect of the space.

[0100] Specifically, such as Figure 1 and Figure 2As shown, each body 104 is provided with two upper and lower oil guiding chambers 114, and each body 104 is provided with two fins 106. The two fins 106 are located on both sides of the line connecting the centers of the two oil guiding chambers 114, and along the width direction of the fins 106, the two fins 106 are located on both sides of the oil passage 116, so that the two fins 106 surround the oil passage 116, so that a high-temperature hot airflow is formed inside, which enhances the thermal convection effect. At the same time, the fins 106 do not completely seal the gap between two adjacent bodies 104. That is, in two adjacent bodies 104, the fins 106 are set on one body 104 and there is a gap between them and the other body 104, so that external cold air can enter the internal high-temperature zone through the gap, increasing the airflow convection effect.

[0101] Furthermore, along the line connecting the centers of two adjacent oil guide chambers 114 on the same body 104, the length X of the fin 106 is less than the distance between the two oil guide chambers 114, and the fin 106 is located between the lines connecting the centers of the two oil guide chambers 114, not exceeding the center of either oil guide chamber 114. Thus, in the direction of the line connecting the centers of the two oil guide chambers 114 on the same body 104, both ends of the body 104 have sufficient air inlet and outlet space, allowing cold air to be replenished between the two bodies 104 at any time.

[0102] Furthermore, a through hole 112 is provided on the body 104 between the flange structure 110 and the fin 106. The through hole 112 increases the thermal resistance at this location, thereby allowing heat to be distributed to the fin 106 and flange structure 110 located on both sides of the through hole 112, making the heat dissipation more uniform.

[0103] Furthermore, the distance L between adjacent bodies 104 is greater than or equal to 25mm and less than or equal to 35mm. On the one hand, this reduces the spacing between adjacent bodies 104, making the overall volume of the heat dissipation component 100 smaller. On the other hand, it makes it easier for a significant thermal difference to form between adjacent bodies 104, thereby accelerating the formation of the chimney effect and quickly dissipating heat through the chimney effect.

[0104] The embodiments proposed in this application enable the entire heat dissipation component 100 to achieve a better heat dissipation effect in a smaller volume, thereby improving the heating effect of the heat dissipation component 100 and reducing the surface temperature of the heat dissipation component 100.
