The invention is capable of other and different embodiments and its several details are capable of modifications and various other uses and applications, all of which are obvious from the description, without departing from the spirit of the invention. The drawings of the present invention are merely schematic illustrations, and are not intended to be drawn to actual dimensions. The following embodiments will further illustrate the related art content of the present invention in detail, but the disclosure is not intended to limit the scope of the present invention.
It will be understood that, although the terms "first," "second," "third," etc. may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are used primarily to distinguish one element from another element or signal from another signal. In addition, the term "or" as used herein shall include any one or combination of more of the associated listed items as the case may be.
Referring to fig. 1 to 9, the present invention discloses a curved temperature equalizing plate 100, which is in a non-flat plate-like configuration and can be applied on a curved object surface (e.g., a circular arc surface, or at least two surfaces of a three-dimensional object that are connected to each other at an angle). That is, any flat plate-shaped temperature equalization plate (e.g., flat plate-shaped L-shaped temperature equalization plate) is not the curved temperature equalization plate 100 according to the present invention.
Further, the curved soaking plate 100 includes a curved outer cover 1, a curved inner cover 2, a capillary structure 3, and a working fluid 4 (see fig. 5). The curved outer cover 1 has a first joint block 11 with a ring shape and a first action block 12 located inside the first joint block 11, and the curved inner cover 2 has a second joint block 21 with a ring shape and a second action block 22 located inside the second joint block 21. The term "annular" refers to various closed annular forms, such as polygonal annular, circular annular, elliptical annular, or irregular annular.
Furthermore, the curved outer cap 1 and the curved inner cap 2 are bonded and fixed to each other by the first bonding block 11 and the second bonding block 21, and collectively enclose a heat flow space S which is closed. The capillary structure 3 and the working fluid 4 are both located in the heat flow space S. Wherein the area of the outer surface 121 of the curved outer cap 1 on the first action zone 12 is larger than the area of the outer surface 221 of the curved inner cap 2 on the second action zone 22.
Accordingly, the disclosed curved samming board 100 meets a predetermined structural condition (e.g., the area of the outer surface 121 of the first action block 12 is larger than the area of the outer surface 221 of the second action block 22) by the curved outer cover 1 and the curved inner cover 2, so that the curved samming board 100 that can be applied on a curved object surface can be precisely formed after the curved outer cover 1 and the curved inner cover 2 are bonded and fixed to each other at the first bonding block 11 and the second bonding block 21.
In addition, the specific structure of the curved soaking plate 100 can be adjusted and changed according to the requirements of the invention as long as the curved soaking plate meets the above conditions. However, in order to facilitate understanding of the curved temperature-equalizing plate 100 of the present invention, some possible embodiments of the curved temperature-equalizing plate 100 in the present invention will be described below, but the present invention is not limited thereto.
Example one
Please refer to fig. 1 to 5, which illustrate a first embodiment of the present invention. The first joint block 11 and the second joint block 21 may be fixed to each other by welding in the present embodiment, but the invention is not limited thereto. That is, in other embodiments of the present invention (not shown), the first joint block 11 and the second joint block 21 may be joined and fixed by other means than welding (e.g. forging).
Furthermore, at least 95% of the volume of the curved inner cap 2 is located within the space enclosed by the curved outer cap 1; stated another way, the second active region 22 of the curved inner cap 2 is located substantially inside the first active region 12 of the curved outer cap 1. Wherein the outer surface 121 of the first active block 12 is spaced apart from the outer surface 221 of the second active block 22 by a maximum distance Dmax of no more than 3 millimeters (mm).
In more detail, the first action block 12 of the curved outer cap 1 comprises a groove 123 concavely provided on the inner surface 122 thereof and a plurality of protrusions 124 extending from the inner surface 122 and located in the groove 123, and the second action block 22 of the curved inner cap 2 is not formed with any groove or protrusion on the inner surface 222 thereof (e.g. the inner surface 222 of the second action block 22 is preferably smooth), while the capillary structure 3 is located in the groove 123 and is abutted against the plurality of protrusions 124.
In order to make the curved temperature equalizing plate 100 have a better temperature equalizing effect (e.g. the working fluid 4 can flow smoothly in the heat flow space S), the first acting block 12 of the curved outer cover 1 and the second acting block 22 of the curved inner cover 2 preferably meet the conditions described in the following paragraphs, but the present invention is not limited thereto.
For example, the outer surface 121 of the first active block 12 has a first outer radius of curvature that is greater than a second outer radius of curvature of the outer surface 221 of the second active block 22. Furthermore, the inner surface 122 of the first active block 12 has a first inner radius of curvature that is less than the first outer radius of curvature, the inner surface 222 of the second active block 22 has a second inner radius of curvature that is greater than the second outer radius of curvature, and the first inner radius of curvature is greater than the second inner radius of curvature.
In other words, the radii of curvature of the curved temperature-equalizing plate 100 are gradually reduced from the outer side to the inner side according to the order from large to small, that is: the first outer radius of curvature, the first inner radius of curvature, the second inner radius of curvature, and the second outer radius of curvature.
Further, the outer surface 121 of the first active block 12 has two first end sections 1211 and a first curved section 1212 connected between the two first end sections 1211, and the outer surface of the second active block 22 has two second end sections 2211 and a second curved section 2212 connected between the two second end sections 2211.
Wherein the two first end sections 1211 and the two second end sections 2211 are both planar, and the normal vectors of the two second end sections 2211 intersect each other to form an included angle α, which is preferably not greater than 180 degrees, but the invention is not limited thereto. That is, the normal vectors of the two second end segments 2211 are formed at any angle consistent with the included angle α of the present invention, as long as they are not parallel to each other.
Furthermore, the first curved section 1212 is parallel to the second curved section 2212, so that the heat flow space S of the curved isopipe 100 can maintain an equal width of flow path at the curved portion. Accordingly, when the working fluid 4 flows along a heat transfer circuit in the heat flow space S and the heat transfer circuit passes between the first curved section 1212 and the second curved section 2212, the working fluid 4 can smoothly flow along the heat transfer circuit.
It should be noted that, in the present embodiment, the outer surface 121 of the first acting block 12 is parallel to the outer surface 221 of the second acting block 22, so that the flow channel in the heat flow space S can maintain the same width, and the working fluid 4 can smoothly flow along the heat transmission circuit. The invention is not limited thereto. For example, in other embodiments of the present invention not shown, the first active area 12 of the curved temperature-equalizing plate 100 may omit the two first end sections 1211 and the corresponding portions thereof, and the second active area 22 may omit the two second end sections 2211 and the corresponding portions thereof.
Example two
Please refer to fig. 6 and 7, which illustrate a second embodiment of the present invention. Since this embodiment is similar to the first embodiment, the same parts of the two embodiments will not be described again, and the differences between the present embodiment and the first embodiment are described as follows:
in the present embodiment, the first acting block 12 of the curved cover 1 is a smooth surface, and the groove 123 and the protrusions 124 thereof shown in fig. 3 of the first embodiment are not formed. Furthermore, the second action block 22 of the curved inner cap 2 comprises a groove 223 concavely arranged on the inner surface 222 thereof and a plurality of protrusions 224 extending from the inner surface 222 and located in the groove 223, and the capillary structure 3 is located in the groove 223 and abuts against the plurality of protrusions 224.

Since the present embodiment is similar to the first and second embodiments, the same parts of the two embodiments will not be described again, and the differences between the first and second embodiments are described below:

It should be noted that, according to the disclosure of the curved temperature-equalizing plate 100 in the first to third embodiments, it can be seen that: at least one of the first active area 12 of the curved outer cap 1 and the second active area 22 of the curved inner cap 2 comprises the groove 123, 223 concavely provided on the inner surface 122, 222 thereof and a plurality of protrusions 124, 224 extending from the inner surface 122, 222 and located in the groove 123, 223, and the capillary structure 3 is located in the groove 123, 223 and is abutted against the plurality of protrusions 124, 224.
