Detailed Implementation

[0045] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] In the embodiments described in this application, it should be noted that, unless otherwise stated and limited, the term "connection" should be interpreted broadly. For example, it can be an electrical connection, or a connection between two internal components. It can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above term according to the specific circumstances.

[0047] It should be noted that the terms "first," "second," and "third" used in the embodiments of this application are merely used to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted. It should be understood that the objects distinguished by "first," "second," and "third" can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.

[0048] The following combination Figures 1 to 5 The heat dissipation device described in the embodiments of this application will be described in detail.

[0049] The heat dissipation device includes a body 110 and a guide body 120. The body 110 has a first receiving cavity 101, a first opening 111, and a second opening 112, and is used to dissipate heat for the heat-generating components. The guide body 120 is disposed in the first receiving cavity 101 and has a first air guiding channel. At least a portion of the first air guiding channel is curved. Gas can flow within the first opening 111, the first air guiding channel, and the second opening 112. The curved first air guiding channel of the guide body 120 increases the path and time of gas flow within the body 110, allowing for more thorough heat exchange between the gas and the body 110, thus greatly improving the heat dissipation capacity of the heat dissipation device.

[0050] In this embodiment, the structure of the body 110 is not limited. For example, as Figure 1 As shown, the body 110 can be a cuboid structure. Alternatively, the body 110 can also have an irregular shape.

[0051] Here, the first opening 111 and the second opening 112 are respectively connected to the first receiving cavity 101, and the positions of the first opening 111 and the second opening 112 are not limited. For example, as Figure 1 As shown, the first opening 111 and the second opening 112 can be located on adjacent sides of the body 110. Of course, the first opening 111 and the second opening 112 can also be located on opposite sides of the body 110.

[0052] Here, the material of the body 110 is not limited. For example, the material of the body 110 can be copper, which is used to increase the thermal conductivity of the body 110.

[0053] In this embodiment, the structure of the air guide 120 is not limited. For example, the air guide 120 can be a mesh structure. As another example, the air guide 120 can be a foam structure; for instance, the air guide 120 can be foamed metal.

[0054] As an example, the air guide 120 may include a first strip-shaped portion and a second strip-shaped portion. The second strip-shaped portion and the first strip-shaped portion are interleaved to form the air guide 120.

[0055] Here, the cross-sectional shape of the second strip can be the same as or different from that of the first strip. For example, the cross-sections of the second strip and the first strip can both be circular or elliptical, and the diameter of the second strip is different from that of the first strip, so as to form a first air guide channel with a larger cross-sectional area between the second strip and the first strip.

[0056] Here, the air guide 120 may include a foam portion, which may be adhered to the surfaces of the second strip portion and the first strip portion to further increase the contact area between the gas and the second strip portion and the first strip portion, so that the gas can exchange heat more fully with the second strip portion and the first strip portion.

[0057] The structure of the foam section is not limited here. For example, the foam section can be foam metal.

[0058] Here, a first air guide channel is provided inside the air guide body 120. The first air guide channel can be entirely curved or partially curved. When the air guide body 120 is a mesh structure or a foam structure, a curved first air guide channel can be formed within the mesh structure or foam structure.

[0059] As an example, the air guide 120 may also have a fifth air guide channel 105.

[0060] Here, the cross-sectional area of ​​the fifth air guide channel 105 is larger than that of the first air guide channel, so that more gas can be introduced into the air guide body 120 through the fifth air guide channel 105.

[0061] Here, the fifth air guide channel 105 can have a straight structure, such as... Figure 5 As shown. Of course, the fifth air guide channel 105 can also be a curved structure, such as... Figure 4 As shown.

[0062] Here, the fifth air guide channel 105 can be connected to the first opening 111 and the second opening 112 respectively, such as Figure 4 As shown, the first air guide channel can also be connected only to the first opening 111, such as... Figure 5 As shown; at this time, the gas can enter the fifth air guide channel 105 through the first opening 111, and then exit through the second opening 112 through the first air guide channel. Of course, the gas can also enter the fifth air guide channel 105 through the first air guide channel via the second opening 112, and then exit through the first opening 111.

[0063] Here, the manner in which the air guide 120 is disposed within the first receiving cavity 101 is not limited. For example, the air guide 120 may contact the wall forming the first receiving cavity 101, but the air guide 120 may not be connected to the wall forming the first receiving cavity 101. Another example is that the air guide 120 may be connected to the wall forming the first receiving cavity 101 by thermally conductive adhesive. Yet another example is that the air guide 120 and the body 110 may be formed as an integral structure by sintering, in which case the heat from the heating element can be transferred to the air guide 120 more quickly.

[0064] Here, the material of the air guide 120 is not limited. For example, the material of the air guide 120 can be copper.

[0065] In some optional implementations of the embodiments of this application, such as Figure 2 As shown, the main body 110 may include: a first wall 114 and a second wall 115. The first wall 114 is connected to the air guide 120 and is used to connect to the heating element; the second wall 115 is spaced apart from the first wall 114; the air guide 120 is located between the first wall 114 and the second wall 115, and the air guide 120 and the second wall 115 form a second air guide channel 102 so that gas can also flow in the second air guide channel, reducing the resistance of gas flow between the first opening 111 and the second opening 112.

[0066] In this implementation, the first wall 114 is connected to the air guide 120 so that the heat from the heating component can be quickly transferred to the air guide 120.

[0067] Here, the connection between the first wall 114 and the air guide 120 is the same as the connection between the air guide 120 and the wall forming the first receiving cavity 101, which will not be described again here.

[0068] Here, the second air guide channel 102 may be connected to at least one of the first opening 111 and the second opening 112, or the second air guide channel 102 may not be connected to either the first opening 111 or the second opening 112.

[0069] In this implementation, such as Figure 3 As shown, the main body 110 may further include a third wall 116 and a fourth wall 117. The third wall 116 is connected to the first wall 114 and the second wall 115 respectively, and the third wall 116 and the air guide body 120 form a third air guide channel 103; the fourth wall 117 is connected to the first wall 114 and the second wall 115 respectively, and the fourth wall 117 is disposed opposite to the third wall 116, and the fourth wall 117 and the air guide body 120 form a fourth air guide channel 104; so that gas can also flow in the third air guide channel 103 and the fourth air guide channel 104, reducing the resistance to gas flow between the first opening 111 and the second opening 112.

[0070] Here, the third air guide channel 103 may be connected to at least one of the first opening 111 and the second opening 112, or the third air guide channel 103 may not be connected to either the first opening 111 or the second opening 112.

[0071] Here, the fourth air guide channel 104 may be connected to at least one of the first opening 111 and the second opening 112, or the fourth air guide channel 104 may not be connected to either the first opening 111 or the second opening 112.

[0072] As an example, such as Figure 3 As shown, the main body 110 may further include a fifth wall 118 and a sixth wall 119. The fifth wall 118 is connected to the first wall 114 and the second wall 115 respectively, and is also connected to the third wall 116 and the fourth wall 117 respectively. The fifth wall 118 and the air guide body 120 form a sixth air guide channel 106. The sixth wall 119 is connected to the first wall 114 and the second wall 115 respectively, and is also connected to the third wall 116 and the fourth wall 117 respectively. The sixth wall 119 is disposed opposite to the fifth wall 118, and the sixth wall 119 and the air guide body 120 form a seventh air guide channel 107.

[0073] Here, the first opening 111 can be set in the fifth wall 118, and the second opening 112 can be set in the sixth wall 119.

[0074] Here, the second air guide channel 102, the third air guide channel 103, the fourth air guide channel 104, the sixth air guide channel 106 and the seventh air guide channel 107 are connected to each other in order to reduce the resistance to gas flow between the first opening 111 and the second opening 112.

[0075] Of course, only one or at least two of the second air guide channel 102, the third air guide channel 103, the fourth air guide channel 104, the sixth air guide channel 106 and the seventh air guide channel 107 may be provided; in this case, at least one or at least two of the second wall body 115, the third wall body 116, the fourth wall body 117, the fifth wall body 118 and the sixth wall body 119 may form a gap with the air guide body 120, and the remaining walls are connected to the air guide body 120.

[0077] This application also describes an electronic device, which includes a heat-generating component of the heat dissipation device described in this application: the heat dissipation device is used to dissipate heat from the heat-generating component.
