Unless otherwise clearly defined, these words will not be interpreted as idealized or overly formal.
[0077] Please refer to Figures 1-2 . Figure 1 FIG. 1 is a three-dimensional schematic diagram of a temperature vapor chamber 100 according to an embodiment of the present invention. Figure 2 To illustrate Figure 1 Exploded view of the temperature homogenizing plate 100. In this embodiment, Figures 1-2 As shown, the temperature vapor chamber 100 includes a body 110 and a plastic frame 130. The body 110 is configured to abut against an electronic component (not shown) to remove heat generated by the electronic component during operation. The plastic frame 130 provides fixing and protection for the body 110.
[0078] Specifically, the plastic frame 130 includes a first frame body 131 and a covering structure 132. The first frame body 131 surrounds and defines a second space SP2. Figure 1 As shown, the body 110 is at least partially located in the second space SP2 and abuts against the first frame 131 of the plastic frame 130. The temperature plate 100 further includes a liquid injection pipe 120 (such as Figure 2 The injection tube 120 is inserted into the body 110 and at least partially exposed outside the body 110. The covering structure 132 of the plastic outer frame 130 is connected to the inner side of the first frame 131, and the injection tube 120 exposed outside the body 110 is buried in the covering structure 132 of the plastic outer frame 130 (so that Figure 1The injection tube 120 is not shown, so the injection tube 120 exposed outside the body 110 is protected by the covering structure 132, thereby avoiding the injection tube 120 from being damaged by collision. Figures 1-2 As shown, the first frame body 131 is rectangular, and the covering structure 132 is connected to the inner corner of the first frame body 131 , but the present invention is not limited thereto.
[0079] Furthermore, if Figures 1-2 As shown, the plastic frame 130 further includes two second frames 133. The second frames 133 are separated and opposite to each other and define a second space SP2 therein. The second frames 133 are respectively connected to the first frames 131, and the covering structure 132 is connected to one of the two second frames 133. In this embodiment, the second frames 133 and the first frames 131 form a stepped structure.
[0080] Furthermore, if Figure 2 As shown, the body 110 has two opposite first side surfaces 116 and two opposite second side surfaces 117. The first side surfaces 116 and the second side surfaces 117 are alternately arranged to surround the body 110 and are configured to abut against the first frame 131. The second frame 133 is respectively configured to abut against the corresponding first side surfaces 116 and a portion of the second side surfaces 117. Figure 1 As shown, the second side surface 117 is at least partially exposed outside the second frame 133 to define the electroplating area EP. In other words, the electroplating area EP is located on the second side surface 117 and between the second frame 133. In practical applications, the user can use electroplating equipment (not shown) to contact the electroplating area EP and perform electroplating on the outer surface of the body 110.
[0081] In other embodiments, the user may also perform electroplating on the outer surface of the body 110 before placing the body 110 in the plastic outer frame 130. In this case, the user may contact the appropriate position on the outer surface of the body 110 with the electroplating equipment according to the actual situation, without being restricted by the position of the electroplating area EP. After the outer surface of the body 110 is electroplated, the body 110 is placed in the plastic outer frame 130.
[0082] Please refer to Figures 3-4 . Figure 3 To illustrate Figure 2 Section view along line segment AA. Figure 4 To illustrate Figure 2 In this embodiment, as shown in FIG. Figures 3-4As shown, the body 110 includes a bottom plate 111 and a top plate 115. The bottom plate 111 includes a plate body 112, a frame 113 and a plurality of support columns 114. The plate body 112 has a surface SF. The frame 113 is disposed on the surface SF of the plate body 112, and the surface SF of the plate body 112 and the frame 113 together define a first space SP1, and the first space SP1 is configured to accommodate a working fluid (not shown). The support columns 114 are located in the first space SP1 and are distributed on the surface SF of the plate body 112. It is worth noting that in the present embodiment, the support columns 114, the plate body 112 and the frame 113 are an integrally formed structure, so the bottom plate 111 has good structural strength. The top plate 115 abuts against the frame 113 and the support columns 114 to seal the first space SP1.
[0083] Furthermore, if Figure 4 As shown, the frame 113 of the bottom plate 111 has a gap GP, the gap GP is connected to the first space SP1, and the injection pipe 120 is configured to pass through the gap GP. Specifically, the injection pipe 120 has a first end 120a and a second end 120b opposite to each other, the first end 120a is located in the first space SP1, and the second end 120b is exposed outside the body 110. In this embodiment, as shown in FIG. Figure 4 As shown, the support column 114 is cylindrical, but the present invention is not limited thereto.
[0084] Furthermore, if Figures 3-4 As shown, the temperature plate 100 further includes a first structural plate 170 and a second structural plate 180. The first structural plate 170 is located in the first space SP1 and is disposed on the surface SF. The first structural plate 170 includes a plurality of first capillary structures 171. The first capillary structures 171 are located on the side of the first structural plate 170 away from the surface SF. The second structural plate 180 is located in the first space SP1 and is disposed on the top plate 115. The second structural plate 180 includes a plurality of second capillary structures 181. The second capillary structures 181 are located on the side of the second structural plate 180 facing the surface SF. In practical applications, according to actual conditions, the first capillary structure 171 and the second capillary structure 181 can be tiny protruding structures, recessed structures or mesh structures, etc., but the present invention is not limited thereto.
[0085] When the temperature plate 100 is in operation, the working fluid contained in the first space SP1 will change its phase by repeated evaporation and condensation, thereby playing a role in heat transfer. The first capillary structure 171 of the first structural plate 170 and the second capillary structure 181 of the second structural plate 180 are configured to improve the efficiency of evaporation and condensation of the working fluid in the first space SP1. It is worth noting that, as mentioned above, since the support column 114, the plate body 112 and the frame 113 are an integrally formed structure, the bottom plate 111 has good structural strength. In this way, when the temperature plate 100 is in operation, the chance of deformation or even damage of the temperature plate 100 due to heat can be effectively reduced, and the flatness of the temperature plate 100 can also be effectively maintained. Therefore, the operating performance and service life of the temperature plate 100 are effectively improved.
[0086] Please refer to Figures 5-6 . Figure 5 FIG. 1 is a three-dimensional schematic diagram illustrating a temperature vapor chamber 300 according to another embodiment of the present invention. Figure 6 To illustrate Figure 5 A partial cross-sectional view along line segment BB. In this embodiment, Figures 5-6 As shown, the temperature plate 300 includes a body 310, a plastic frame 330 and a metal frame 350. The plastic frame 330 includes two third frames 331 and a covering structure 332. The third frames 331 are separated and opposite to each other and define a second space SP2 therein. The covering structure 332 is connected to one of the two third frames 331 and is configured to cover the injection pipe ( Figures 5-6 Not shown, please refer to Figure 2 , 4 ). The third frame 331 and the metal frame 350 surround and connect the body 310 respectively, and the third frame 331 is at least partially stacked on the metal frame 350. For example, the metal frame 350 can be connected to the body 310 by spot welding, riveting, laser welding, etc. to strengthen the overall structural strength of the temperature vapor chamber 300, and the metal frame 350 can be made of copper, titanium, iron or stainless steel to improve its strength, but the present invention is not limited thereto.
[0087] Through the above-mentioned temperature evaporating plate 100, the present invention also provides a manufacturing method 500 of the temperature evaporating plate 100 / 300. For example, please refer to Figure 7 . Figure 7 FIG. 5 is a flow chart showing a method 500 for manufacturing a temperature vapor chamber 100 according to an embodiment of the present invention. Figure 7 As shown, the manufacturing method 500 includes the following steps (it should be understood that in some embodiments, the steps mentioned, except for those whose order is specifically described, can be adjusted in sequence according to actual needs, and can even be performed simultaneously or partially simultaneously):
[0088] (1) The bottom plate 111 is formed in an integral manner by forging. As described above, the bottom plate 111 includes a plate body 112, a frame 113, and a plurality of support columns 114, and the frame 113 and the support columns 114 protrude from the surface SF of the plate body 112. The support columns 114 are separated from each other and distributed on the surface SF of the plate body 112, and the frame 113 surrounds the support columns 114 (please also refer to Figure 4 ), the surface SF and the frame 113 together define a first space SP1, and the first space SP1 is configured to accommodate a working fluid (step 501). It is worth noting that since the bottom plate 111 including the plate body 112, the frame 113 and the plurality of support columns 114 is made from a single plate (not shown) by forging, the bottom plate 111 is an integrally formed structure, so that the process of placing the support columns 114 on the plate body 112 can be saved, so that the manufacturing time and production cost of the bottom plate 111 can be effectively reduced.
[0089] (2) The top plate 115 is abutted against the frame 113 and the support column 114 to seal the first space SP1 to form the main body 110 (step 502 ).
[0090] Furthermore, before the top plate 115 is abutted against the frame 113 and the support column 114, the manufacturing method 500 further includes the following two steps:
[0091] (3) Set the first structural plate 170 (see Figures 3-4 ) on the surface SF in the first space SP1, the first structure plate 170 includes a plurality of first capillary structures 171, and the first capillary structures 171 are located on a side of the first structure plate 170 away from the surface SF.
[0092] (4) Set up the second structural plate 180 (see Figures 3-4 ) is located on a side of the top plate 115 facing the first space SP1. The second structure plate 180 includes a plurality of second capillary structures 181. The second capillary structures 181 are located on a side of the second structure plate 180 facing the surface SF.
[0093] Furthermore, the manufacturing method 500 further comprises:
[0094] (5) The first space SP1 is evacuated through the injection tube 120 (step 503). Specifically, before or after the top plate 115 abuts against the frame 113 and the support column 114, the user sets the injection tube 120 in the notch GP of the frame 113. As shown in FIGS. 2 and 4, the injection tube 120 has a first opening OP1 and a second opening OP2 opposite to each other. The first opening OP1 is located in the first space SP1, and the second opening OP2 is exposed to the outside of the body 110. The first opening OP1 and the second opening OP2 are connected to each other. Through the injection tube 120, the user evacuates the first space SP1.
[0095] (6) The working fluid is introduced into the first space SP1 through the liquid injection pipe 120 (step 504).
[0096] (7) After an appropriate amount of working fluid is introduced into the first space SP1, the injection tube 120 is closed so that the first opening OP1 and the second opening OP2 are no longer connected to each other (step 505). At this point, the body 110 of the temperature equalizing plate 100 is also completed. Specifically, the injection tube 120 has a first end 120a and a second end 120b opposite to each other, the first opening OP1 is located at the first end 120a, and the first end 120a is located in the first space SP1, and the second opening OP2 is located at the second end 120b, and the second end 120b is exposed outside the body 110.
[0097] When the body 110 of the temperature vapor chamber 100 is manufactured, the manufacturing method 500 further includes:
[0098] (8) Fix the body 110 in a mold (not shown) and perform injection molding in the mold to form a plastic frame 130 (step 506). It should be understood that the injected plastic can withstand high temperatures, have high bonding strength, and have a similar thermal expansion coefficient, such as epoxy resin or others. For example, the material of the plastic frame 130 is usually made of a material with good strength, thermal expansion properties close to the body 110, and can withstand the high temperature of packaging reflow soldering, such as epoxy molding compound (EMC), silicone resin, liquid crystal polymer (LCP), PPA resin (polyphthalamide) or others.
[0099] Specifically, in this embodiment, the plastic frame 130 includes a first frame body 131 and a coating structure 132, the first frame body 131 surrounds and defines a second space SP2, the body 110 is at least partially located in the second space SP2 and abuts against the first frame body 131 of the plastic frame 130, the coating structure 132 is connected to the inner side of the first frame body 131, and the injection tube 120 exposed outside the body 110 is buried in the coating structure 132 of the plastic frame 130. In this way, the injection tube 120 exposed outside the body 110 is protected by the coating structure 132, thereby avoiding the chance of the injection tube 120 being damaged by collision, and reducing the risk of leakage of the working fluid from the body 110.
[0100] As described above, the plastic outer frame 130 further includes two second frames 133. The second frames 133 are separated and opposite to each other, and define a second space SP2 therein. The second frames 133 are respectively connected to the first frames 131, and the covering structure 132 is connected to one of the second frames 133. In this embodiment, the second frame 133 and the first frame 131 form a stepped structure, but the present invention is not limited thereto. According to actual conditions, the appearance features of the second frame 133 and the first frame 131 can also adopt different designs.
[0101] Furthermore, the main body 110 has two opposite first side surfaces 116 and two opposite second side surfaces 117. The first side surfaces 116 and the second side surfaces 117 are alternately arranged to surround the main body 110 and abut against the first frame 131. The second frame 133 abuts against the corresponding first side surfaces 116 and a portion of the second side surfaces 117 respectively. The second side surfaces 117 are at least partially exposed outside the second frame 133 to define the electroplating area EP.
[0102] In other embodiments, the manufacturing method 500 may further include:
[0103] (9) Use electroplating equipment (not shown) to contact the electroplating area EP (see Figure 1 ), and electroplating is performed on the outer surface of the body 110 (step 507).
[0104] In other embodiments, the user may also perform electroplating on the outer surface of the body 110 before the body 110 is disposed in the plastic outer frame 130. In this case, the user may contact the appropriate position on the outer surface of the body 110 with the electroplating equipment according to the actual situation, without being restricted by the position of the electroplating area EP. When the outer surface of the body 110 is electroplated, the above step 506 is repeated.
[0105] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:
[0106] (1) Since the support column, plate body and frame are an integrated structure, the bottom plate has good structural strength. In this way, when the vapor chamber is in operation, the chance of deformation or even damage due to heat can be effectively reduced, and the flatness of the vapor chamber can be effectively maintained. Therefore, the operating performance and service life of the vapor chamber can be effectively improved.
[0107] (2) Since the base plate including the plate body, the frame and the plurality of support columns is made from a single plate by forging, the base plate is an integrally formed structure, and the manufacturing time and production cost of the base plate can be effectively reduced.
[0108] (3) Since the injection tube exposed outside the body is embedded in the covering structure of the plastic outer frame, the injection tube exposed outside the body is protected by the covering structure, thereby avoiding the chance of the injection tube being damaged by collision and reducing the risk of leakage of the working fluid from the body.
[0109] Although the present invention has been disclosed as above in the form of an implementation method, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the attached claims.
