Detailed Description
In order to more clearly understand the technical features, objects and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings, in which the same reference numerals indicate the same or structurally similar but functionally identical elements.
"exemplary" means "serving as an example, instance, or illustration" herein, and any illustration, embodiment, or steps described as "exemplary" herein should not be construed as a preferred or advantageous alternative.
For the sake of simplicity, the drawings only schematically show the parts relevant to the present invention, and they do not represent the actual structure as a product.
Fig. 1 is a perspective view and fig. 2 is a corresponding plan view of an exemplary embodiment of a heat exchange element. As shown in fig. 1 and 2, the heat exchanging member 10 includes a heat conductive base 20 and a plurality of heat dissipating studs 30 (only one of which is schematically illustrated). The heat conductive base 20 is used to contact a heat source to conduct heat away from the heat source. In the present exemplary embodiment, the heat conducting base 20 is in a column shape, and one end surface (i.e., the lower end surface in fig. 1) thereof is used for contacting with a heat source, for example, and the other end surface 21 is used for contacting with the heat dissipation posts 30, which is advantageous for uniformly guiding the heat of the heat source to the heat dissipation posts. But is not limited thereto.
Fig. 3 is a schematic structural view of one of the heat-dissipating studs of the heat-exchanging element shown in fig. 2. As shown in fig. 3, each heat dissipating stud 30 includes a heat conducting axial core 31 and a plurality of fins 32 (only one of which is schematically indicated) connected to the heat conducting axial core 31. Referring to fig. 1 and 3, the heat conducting shaft core 31 extends along a first direction D1 of the heat exchanging member 10 parallel to the axial direction of the heat conducting base 20, and mainly plays a role of heat conduction. The primary purpose of the fins 32 is to increase the heat dissipation surface. One end of the heat conductive shaft core 31 in the first direction D1 is connected to the heat conductive base 20. In the present exemplary embodiment, the fins 32 extend in the first direction D1 to be flush with both ends of the heat conductive shaft core 31. The plurality of fins 32 of each heat radiation column 30 are distributed around the circumferential direction C of the heat conductive shaft core 31 perpendicular to the first direction D1.
As shown in fig. 1 and 2, the heat radiation columns 30 of the group are distributed in such a manner that the outer periphery is gradually reduced from the center in the ratio of the minimum cross-sectional area to the surface area of the heat radiation columns 30, centered on a heat radiation axis L of the heat exchange member 10 parallel to the first direction D1. The minimum cross-sectional area of each heat-dissipating stud 30 is the smallest area of the cross-section perpendicular to the first direction D1. In the present exemplary embodiment, since the fins 32 extend in the first direction D1 to be flush with both ends of the heat conductive shaft core 31, the cross-sectional areas of the heat radiation column 30 at different positions in the first direction D1 are the same. The surface area of each heat-dissipating stud 30, i.e., the surface area of the heat exchanging element 10 that is in contact with the outside through the heat-dissipating stud 30, does not include the area in contact with the heat-conducting base 20.
In the present exemplary embodiment, the heat dissipation axis L is located approximately at the geometric center of the overall structure made up of the set of heat dissipation studs 30. Specifically, in the present exemplary embodiment, the heat-dissipating stud 30 constitutes a generally cylindrical structure, with the heat-dissipating axis L lying on the axis of the cylinder. Such a structure is suitable for the case of uniform heat distribution of the heat source. However, in other exemplary embodiments, the position of the heat dissipation axis L may be set according to the heat distribution of the heat source, and the heat dissipation axis L may be set as close to a portion where the heat quantity is high as possible, for example.
This heat transfer 10 can do benefit to the central heat and derive with faster speed to distribute away the heat through heat radiation structure, borrow this to optimize the comprehensive effect of heat conduction and surface heat transfer in order to improve heat exchange efficiency.
In the exemplary embodiment, the set of heat radiation columns 30 are distributed with the heat radiation axis L as a center in such a manner that the cross-sectional area of the heat conductive shaft core 31 gradually decreases from the center to the outer periphery. This facilitates an increase in the overall heat transfer efficiency.
In other exemplary embodiments, the fins 32 may be provided in other forms. FIG. 4 shows a cross-sectional view of another illustrative embodiment of a heat-dissipating stud, shown in FIG. 4 with fins 32 extending in a first direction D1. The plurality of fins 32 of each heat-dissipating stud 30 are divided into a plurality of groups. The fins 32 of each group are arranged along the first direction D1, with a gap 34 between each adjacent two fins 32 of the same group. The plurality of sets of fins 32 are distributed around the circumferential direction C of the heat conductive shaft core 31 perpendicular to the first direction D1. The gap 34 is arranged to facilitate turbulence of the fluid in the heat exchange member 10, thereby improving heat exchange efficiency.
In the present exemplary embodiment, the heat exchanging element 10 is an integrally formed structure, which is made, for example, by 3D printing technology. The integrated structure is beneficial to improving the integral heat conduction efficiency. But is not limited thereto. The heat exchange element 10 is preferably made of a material with good thermal conductivity, such as copper, aluminum and alloys.
In the illustrated embodiment, the thermally conductive base 20 is cylindrical and the heat-dissipating stud 30 constitutes a generally cylindrical structure. However, in other exemplary embodiments, the shape of the heat conductive base 20 and the arrangement shape of the heat dissipation pillars 30 may be adjusted as needed. Fig. 5 shows a top view of another exemplary embodiment of a heat exchanger element, wherein the thermally conductive base 20 has a rectangular parallelepiped shape and the heat-dissipating stud 30 forms a substantially rectangular parallelepiped structure.
FIG. 6 is a partial cross-sectional view of an exemplary embodiment of a heat exchange assembly. As shown in fig. 6, the heat exchange assembly includes a container 40 and a heat exchange member 10 shown in fig. 1. The container 40 has a receiving chamber 41 and a mounting port 42 communicating with the receiving chamber 41. The heat conducting base 20 is hermetically covered on the mounting opening 42, and the heat dissipation column 30 is located in the cavity 41. The chamber 41 may be filled with a fluid heat exchange medium, for example, during use.
The heat exchange member 10 of the heat exchange assembly can facilitate the conduction of central heat at a high speed, and the heat is dissipated through the heat dissipation structure, so that the comprehensive effect of heat conduction and surface heat exchange is optimized to improve the heat exchange efficiency.
FIG. 7 is a partial cross-sectional view of another illustrative embodiment of a heat exchange assembly. The heat exchange assembly of the exemplary embodiment is the same as or similar to the heat exchange assembly shown in fig. 6, and is not repeated herein, except that the heat exchange assembly further includes a heat accumulator 50 disposed in the cavity 41. The heat accumulator 50 contains a phase change material and contacts the heat sink stud 30. In the present exemplary embodiment, the thermal mass 50 is a mixture of a phase change material and a thermally conductive material. The heat conducting material comprises aluminum nitride powder, alumina powder and/or carbon powder. Thereby facilitating rapid absorption of heat emanating from the heat exchange element 10. Without limitation, in other exemplary embodiments, the thermal mass 50 may also include a porous matrix and a phase change material adsorbed to the porous matrix. The porous matrix is heat-conducting porous ceramic, expanded graphite or foamed aluminum.
