Detailed Implementation

[0034] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0035] A specific embodiment of this utility model discloses a phase change heat absorption device, such as... Figures 1-2 As shown, it includes an outer shell 1, an inner shell 2, a heat transfer assembly 3, and an unlocking component 4. The inner shell 2 is used to hold the phase change material and is placed inside the outer shell 1. The heat transfer assembly 3 passes through the outer shell 1 and contacts the inner shell 2. The unlocking component 4 is connected to the outer shell 1 and is used to open the outer shell 1, thereby enabling the replacement of the phase change material.

[0036] like Figure 2As shown, the heat transfer assembly 3 includes a heat-conducting plate 31 and a heat dissipation plate 32. One side of the heat-conducting plate 31 penetrates the outer shell 1 and contacts the inner shell 2, while the other side contacts the heat source, thereby transferring heat to the inner shell. This causes the phase change material in the inner shell to absorb heat and undergo a phase change, thus dissipating heat from the heat source. One side of the heat dissipation plate 32 contacts the inner shell 2, while the other side penetrates the outer shell 1 and contacts the external environment, thereby dissipating heat from the inner shell 2.

[0037] Preferably, the heat-conducting plate 31 and the heat dissipation plate 32 are made of metal materials with good thermal conductivity, such as copper and aluminum, so as to facilitate the conduction of heat.

[0038] Preferably, multiple heat dissipation strips are provided on the heat dissipation plate 32, thereby increasing the heat dissipation area and accelerating the heat dissipation speed.

[0039] Furthermore, the outer shell 1 includes a disassembly plate 11 and a housing 12, and the inner shell 2 is disposed inside the housing 12. The disassembly plate 11 is connected to the housing 12 and is used to close the inner shell 2.

[0040] like Figures 3-4 As shown, the disassembly plate 11 is provided with connectors 111, and there are multiple connectors 111. The housing 12 is provided with through grooves 121, and the number and shape of the through grooves 121 are matched with the connectors 111. The connectors 111 can enter the through grooves 121, thereby fixing the connection between the disassembly plate 11 and the housing 12.

[0041] like Figure 5 As shown, the disassembly plate 11 also includes a connecting groove 112. A first spring 1111 is provided on the connector 111. The connector 111 is connected to the connecting groove 112 through the first spring 1111. The first spring 1111 supports the connector 111, so that the connector 111 protrudes from the connecting groove 112 and enters the through groove 121, thus fixing the connection between the disassembly plate 11 and the housing 12.

[0042] like Figure 6 As shown, the unlocking component 4 is disposed on the housing 12 and surrounds the housing 12. The unlocking component 4 is provided with pressing blocks 41. The number and shape of the pressing blocks 41 are matched with the through groove 121. The pressing blocks 41 can enter the through groove 121 and press the connector 111, causing the connector 111 to leave the through groove 121, thereby releasing the connection between the disassembly plate 11 and the housing 12.

[0043] like Figure 7 As shown, a second spring 411 is provided on the extrusion block 41. The extrusion block 41 is connected to the unlocking member 4 through the second spring 411. The elastic modulus of the second spring 411 is greater than that of the first spring 1111, so that the extrusion block 41 can extrude the connector 111 out of the through groove 121 under the action of the second spring 411.

[0044] When the inner shell 2 needs to be replaced, the unlocking piece 4 is moved along the shell 12, the pressing block 41 is pressed by the shell 12 to compress the second spring 411, when the unlocking piece 4 is moved to the pressing block 41 and the through slot 121 are matched, the second spring 411 is reset to make the pressing block 41 extrude the connecting head 111 out of the through slot 121, so that the dismounting plate 11 is separated from the shell 12.

[0045] Preferably, the unlocking piece 4 is provided with the ball 42, so as to facilitate the movement of the unlocking piece 4 along the shell 12.

[0046] Preferably, the unlocking piece 4 is provided with the anti-skid pad 43, so as to facilitate the movement of the unlocking piece 4 by the user and prevent slipping.

[0047] Compared with the prior art, the phase change heat absorption device can be separated from the shell 1, so that the phase change material reaches the service life without the need to replace the entire phase change heat absorption device, thereby saving materials and reducing costs. The unlocking piece 4 can facilitate the separation of the dismounting plate 11 and the shell 12, and the dismounting plate 11 and the shell 12 can be separated by sliding the unlocking piece 4 along the shell 12, so that the inner shell 2 can be replaced, and the operation is simple and convenient. The heat transfer assembly 3 can quickly transfer heat to the inner shell 2, so that the phase change material absorbs heat to cool the heat source, and the heat of the inner shell 2 is transferred to the external environment through the heat dissipation plate 32, thereby improving the heat dissipation efficiency.

[0048] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
