Description

Technical Field

[0001] The present invention relates to a heat exchanger, and particularly to a heat exchange device with a locally deformable heating surface. Background Art

[0002] Existing heat exchangers, such as heat pipes. One surface is mainly used as a condensation part, and the other surface is used as a heating part. The heating part is attached to the surface of the heat source to be cooled, so as to help the heat source dissipate heat through heat exchange.

[0003] However, since most heat sources are electronic heating components and are welded and fixed on a circuit board, the surface of the heat source may not be completely horizontal during the above welding and assembly process. At the same time, after the heat exchanger contacts the surface of the heat source, it often needs to be fixed on the circuit board through structures such as fasteners. Therefore, the heating part of the heat exchanger may not be completely horizontal either. When there may be some errors in the assembly of the above two, it is easy to increase the contact error between the heating part of the heat exchanger and the surface of the heat source, resulting in poor surface adhesion and affecting the heat exchange effect. Summary of the Invention

[0004] The main object of the present invention is to provide a heat exchange device with a locally deformable heating surface, which can improve the surface contact by locally deforming the heating surface of the heat exchange device when it contacts the surface of the heat source, so as to maintain good heat exchange capacity.

[0005] To achieve the above object, the present invention provides a heat exchange device with a locally deformable heating surface, including a first plate, a second plate, and at least one elastic member; the second plate is disposed on the first plate and a chamber is formed between the second plate and the first plate, and the elastic member is disposed between the first plate and the second plate; wherein, the second plate has a surrounding portion and a heating surface located within the surrounding portion, and a flexible portion integrally connected between the heating surface and the surrounding portion, the flexible portion surrounds the periphery of the heating surface to suspend the heating surface within the surrounding portion, and the elastic member is disposed between the heating surface and the first plate for elastic support. The flexible portion provides the heating surface with the ability to locally deform, so as to improve the contact between the heating surface and the surface of the heat source and achieve the above object.

[0025] In order to enable your review committee to further understand the features and technical content of the present invention, please refer to the following detailed description and drawings of the present invention. However, the drawings are only for reference and explanation, and are not used to limit the present invention.

[0026] Please refer to Figure 1 and Figure 2 , which are respectively the plan view and the cross-sectional view of the first embodiment of the present invention. The present invention provides a heat exchange device with a locally deformable heat receiving surface, including a first plate member 1, a second plate member 2, and at least one elastic member 3 disposed between the first plate member 1 and the second plate member 2; wherein:

[0027] The first plate member 1 serves as the condensation end of the heat exchange device, and it has a part that can be used to cooperate with the heat dissipation fin 4 (such as Figure 3a bottom 10 in contact (as shown), and side portions 11 formed around the bottom 10. The side portions 11 can be formed around to match the shape of the bottom 10. For example, when the bottom 10 is square, the side portions 11 can be continuously bent to match the geometric shape of the bottom 10 and surround the outer periphery of the bottom 10.

[0028] The second plate member 2 serves as the heat-receiving end of the heat exchange device and is used to cover the first plate member 1 and form a chamber with the first plate member 1. Specifically, the second plate member 2 is used to seal the opening formed at the side portion 11 of the first plate member 1 (as Figure 2 shown), so as to form the chamber between the first plate member 1 and the second plate member 2, and a working fluid (not shown in the figure) can be filled in the chamber through processes such as degassing or vacuum pumping, and then used as a medium for heat exchange.

[0029] As described above, the second plate member 2 has a surrounding portion 20 and a heat-receiving surface 21 located within the surrounding portion 20, and there is a flexible portion 22 integrally connected between the heat-receiving surface 21 and the surrounding portion 20. When the heat-receiving surface 21 is subjected to an external force extrusion, the flexible portion 22 at its periphery can provide a flexural deformation amount to adapt to being in contact with a heat source 5 (i.e., as Figure 3 shown). Further, the cross-section of the flexible portion 22 can be wavy or threaded, and can be formed by stamping processes such as stamping on the upper and lower parts of the second plate member 2 corresponding to the flexible portion 22. On the one hand, the flexible portion 22 is stamped into the aforementioned wavy or threaded shape, and on the other hand, the thickness of the flexible portion 22 is thinned after stamping to provide a certain flexural deformation amount for the heat-receiving surface 21 while maintaining the integral structural relationship between the heat-receiving surface 21 and the surrounding portion 20.

[0030] The elastic member 3 is disposed between the heat-receiving surface 21 of the second plate member 2 and the first plate member 1. When processes such as degassing or vacuum pumping are performed on the chamber between the first plate member 1 and the second plate member 2, the heat-receiving surface 21 can be maintained in a horizontal position with respect to the surrounding portion 20, and at the same time, when the heat-receiving surface 21 contacts the heat source 5 (i.e., as Figure 3 shown), it can provide an elastic force to make the contact between the heat-receiving surface 21 and the heat source 5 closer. In the embodiment of the present invention, the elastic member 3 can be an elastic assembly, such as a compression spring or a conical spring, and is correspondingly located below the heat-receiving surface 21, and can also be provided in multiple numbers and commonly correspond to below the heat-receiving surface 21. Further, between the first plate member 1 and the second plate member 2, a plurality of support structures 32 can also be further provided, and these support structures 32 are located below the surrounding portion 20 of the second plate member 2 and abut against the inside of the bottom 10 of the first plate member 1.

[0031] Therefore, through the above-described structural composition, the heat exchange device with a locally deformable heat-receiving surface of the present invention can be obtained.

[0032] Accordingly, as Figure 3 shown, when the present invention is applied to a heat source 5, the heat receiving surface 21 can be attached to the surface of the heat source 5. At this time, since the heat receiving surface 21 is equivalently suspended within the surrounding portion 20 of the second plate member 2 through the flexible portion 22 at its periphery, when contacting the surface of the heat source 5, the heat receiving surface 21 can cooperate with factors such as the flatness or inclination state of the surface of the heat source 5, and be adjusted through the flexible deformation amount generated by the flexible portion 22, so that the heat receiving surface 21 can indeed achieve a surface-to-surface flat attachment effect with the surface of the heat source 5.

[0033] In addition, as Figure 4 shown, in the second embodiment of the present invention, at least one lateral flexible portion 110 can be further formed on the side portion 11 of the first plate member 1. In this way, the second plate member 2 as a whole can be flexibly deformed with respect to the first plate member 1 through the lateral flexible portion 110, so that the horizontal degrees between the first plate member 1 and the second plate member 2 can be finely adjusted to a more suitable state according to the heat source 5.

[0034] Furthermore, as Figure 5 shown, in the third embodiment of the present invention, at least one bottom surface flexible portion 100 can be further formed on the bottom portion 10 of the first plate member 1, which can be applicable to surface-to-surface contact when attaching to the condensation end (such as when the condensation surface is relatively large).

[0035] In summary, the present invention can indeed achieve the expected usage purpose and solve the deficiencies of the prior art. Moreover, due to its novelty and creativity, it fully meets the requirements for a patent application for an invention patent. Now, an application is filed in accordance with the Patent Law. Please examine it in detail and grant the patent for this case to protect the rights of the inventor.

[0036] The above is only the preferred and feasible embodiment of the present invention, and it does not limit the patent scope of the present invention accordingly. Therefore, all equivalent technologies, means, etc. changes made by using the content of the specification and drawings of the present invention are similarly included within the scope of the present invention. This is hereby stated.
