Description

Technical Field

[0001] The utility model relates to the field of heat dissipation, and in particular to a heat dissipation device which can conveniently fix a water cooling plate and make the water cooling plate closely attached to a heat source. Background Art

[0002] As various electronic devices and electronic components move towards high performance and thinness, the heat energy generated during operation also increases. Therefore, many electronic devices and electronic components currently use liquid cooling in addition to traditional air cooling to ensure that a good heat dissipation effect can be achieved. Among them, liquid cooling often uses a water cooling head or a water cooling plate to dissipate heat from the heat source, so the water cooling head or water cooling plate needs to be fixed on the heat source, and generally the water cooling head or water cooling plate is mostly fixed by a locking method.

[0003] When a water cooling head or a water cooling plate is applied to a connector assembly, since the heat energy is mainly concentrated at the joint between the male connector and the female connector, the water cooling head or the water cooling plate needs to be attached to the connector plug-in to achieve the best heat absorption effect. However, at this time, without excessively adjusting the main structure of the water cooling head or the water cooling plate, additional components are required to fix the water cooling head or the water cooling plate. The current practice is mostly to use elastic buckles to fix the water cooling head or the water cooling plate. However, due to the limitations of the clamping force and force application point of the elastic buckle itself, the heat source cannot be completely attached to the water cooling head or the water cooling plate, and the elastic buckle is also quite inconvenient in disassembly and assembly.

[0004] In view of this, the inventors of the present invention have focused on the shortcomings of the above-mentioned prior art, conducted intensive research and applied theoretical knowledge to try their best to solve the above-mentioned problems, which has become the goal of the inventors' improvement.

These terms may only be used to distinguish one element, component, region, layer, or portion from another. Unless the context clearly indicates, terms such as "first," "second," "third," "fourth," and "fifth" as used herein do not imply a sequence or order.

[0055] The detailed description and technical contents of the present invention are described below with reference to the accompanying drawings. However, the accompanying drawings are only for illustrative purposes and are not intended to limit the present invention.

[0056] The utility model provides a heat dissipation device for dissipating heat from at least one connector B disposed on a substrate A (such as a circuit board or a motherboard, etc.). Figures 1 to 3FIG. 1 is a first embodiment of the heat dissipation device of the present invention, which mainly includes a socket 10 , a fixed cover 20 and at least one water cooling plate 30 .

[0057] The socket 10 is disposed on the substrate A. Specifically, the socket 10 can be fixed on the substrate A by locking, clamping, snapping, bonding, melting, welding, riveting, etc. In the present embodiment, the socket 10 is generally a hollow rectangular shell, but the utility model does not particularly limit the external structure of the socket 10. The socket 10 has at least one plug-in chamber 11 and at least one through slot 12. The plug-in chamber 11 is extended inwardly from the front side of the socket 10 along its longitudinal direction. The number of through slots 12 is configured to correspond to the number of the plug-in chambers 11. In this embodiment, the number of the plug-in chambers 11 and the through slots 12 are both four, and each plug-in chamber 11 is arranged in parallel at intervals, and each through slot 12 is also arranged in parallel at intervals corresponding to each plug-in chamber 11, but the utility model is not limited to the above number. For example, the number of the plug-in chambers 11 and the through slots 12 can also be one, two, three or more than five, depending on the use requirements. For the convenience of description, the following description is only based on a single plug-in chamber 11 and a single through slot 12, which does not limit the utility model to have only one plug-in chamber 11 and through slot 12. The through slot 12 is located at the top of the socket 10 and connected to the plug-in chamber 11, so each through slot 12 in this embodiment is located at the top of the socket 10 and is connected to the corresponding plug-in chambers 11. The plug-in chamber 11 is for the corresponding plug-in of the connector B.

[0058] The fixed cover 20 covers the socket 10 and is fixed to the substrate A. In the present embodiment, the fixed cover 20 includes a shielding plate 21, a pair of extension plates 22 and a pair of fixing plates 23, but the present invention is not limited thereto. Each fixing plate 23 is parallel to the shielding plate 21 and the substrate A, and each fixing plate 23 can be fixed to the substrate A by locking, clamping, buckling, bonding, melting, welding, riveting, etc. The shielding plate 21 covers the top of the socket 10 and has at least one elastic arm 211 extending toward the through slot 12. In the present embodiment, the number of elastic arms 211 is eight and two are arranged in a group corresponding to each through slot 12, but the present invention is not limited thereto. For example, the number of elastic arms 211 can also be only four and respectively corresponding to each through slot 12. For the convenience of description, the following description is only based on a single elastic arm 211, which does not limit the present invention to have only one elastic arm 211. Each extension plate 22 is connected between two opposite sides of the shielding plate 21 and each fixing plate 23. In this embodiment, each extension plate 22 is vertically connected to the shielding plate 21 and the corresponding fixing plate 23, but in other embodiments, it can also be connected in an inclined manner, an arc connection or other connection methods.

[0059] In the present embodiment, the number of water-cooling plates 30 is four and they are respectively configured corresponding to each through slot 12, but the present invention is not limited to this. For the convenience of description, only a single water-cooling plate 30 is used for explanation below, which does not limit the present invention to have only one water-cooling plate 30. The water-cooling plate 30 is configured between the plug socket 10 and the fixed cover 20 corresponding to the elastic arm 211 and the through slot 12. In the present embodiment, the water-cooling plate 30 is generally a long rectangular plate body, so that it can be arranged in parallel between the plug socket 10 and the fixed cover 20 at intervals, but the appearance of the water-cooling plate 30 of the present invention is not limited to the above. The bottom of the water-cooling plate 30 protrudes a contact portion 31 corresponding to the through slot 12, that is, when the connector B is not inserted into the plug-in chamber 11, the contact portion 31 is inserted through the through slot 12 of the plug-in socket 10 to the plug-in chamber 11. The water cooling plate 30 is connected to a liquid inlet pipe 32 and a liquid outlet pipe 33, so that the cooling liquid flows through the water cooling plate 30. In this embodiment, the liquid inlet pipe 32 and the liquid outlet pipe 33 are respectively arranged at one end of the water cooling plate 30 away from the plug-in chamber 11 to facilitate the routing of the pipelines, but the utility model is not limited thereto.

[0060] Please refer to Figure 4 and Figure 5 As shown, when the connector B is inserted into the plug-in chamber 11, the top of the connector B will press against the contact portion 31 at the bottom of the water-cooling plate 30 to push up the water-cooling plate 30. The heat dissipation device of the utility model can elastically push against the top of the water-cooling plate 30 by fixing the elastic arm 211 of the cover shell 20, so that the contact portion 31 at the bottom of the water-cooling plate 30 can still remain tightly attached to the top of the connector B, thereby effectively utilizing the water-cooling plate 30 to dissipate heat for the connector B.

[0061] For further explanation, see Figure 1 and Figure 2 As shown, the elastic arm 211 is parallel to the water-cooling plate 30, and the elastic arm 211 elastically pushes against the side of the water-cooling plate 30 away from the through slot 12 corresponding to the position of the contact portion 31, thereby enabling the elastic push of the elastic arm 211 to achieve the best effect. However, the setting position and direction of the elastic arm 211 of the utility model are not limited to the upper part, as long as the elastic arm 211 can elastically contact the side of the water-cooling plate 30 away from the through slot 12. In addition, in this embodiment, the elastic arms 211 in a group of two are arranged relative to each other and arranged on the same straight line, so as to further enhance the push effect on the water-cooling plate 30, so that the contact portion 31 at the bottom of the water-cooling plate 30 can be closely attached to the top of the connector B.

[0062] See also Figures 1 to 5As shown, the heat dissipation device of this embodiment also includes at least one positioning member 40. In this embodiment, the number of positioning members 40 is eight and they are arranged in groups of two corresponding to each water-cooling plate 30, but the present invention is not limited thereto. For example, the number of positioning members 40 may be only four and they are arranged corresponding to each water-cooling plate 30, respectively. For the convenience of description, only a single positioning member 40 is used for description below, but the present invention is not limited to having only one positioning member 40. The shielding plate 21 of the fixed cover 20 has a through hole 212, and the water-cooling plate 30 has a fixing hole 34 on the side facing the shielding plate 21. The positioning member 40 in this embodiment is a positioning pin and includes a stopper 41, a sliding portion 42 and a fixing portion 43, but the present invention is not limited thereto. The sliding portion 42 of the positioning member 40 is movably connected to the through hole 212 of the fixed housing 20, the fixing portion 43 is fixed in the fixing hole 34 of the water-cooling plate 30 in a clamping or locking manner, and the stopper 41 is stopped at the side of the fixed housing 20 away from the water-cooling plate 30. In this way, the sliding portion 42 of the positioning member 40 is movably restricted in the through hole 212 of the fixed housing 20, so that the water-cooling plate 30 can be positioned without being separated from the heat dissipation device, and when the connector B is inserted into the plug-in chamber 11 and the water-cooling plate 30 is pushed upward, the positioning member 40 can also move upward relatively through the through hole 212 of the fixed housing 20 without causing the positioning member 40 to push the fixed housing 20.

[0063] Furthermore, in order to facilitate fixing the fixing portion 43 of the positioning member 40 in the fixing hole 34 of the water-cooled plate 30, the water-cooled plate 30 in this embodiment also extends downward to form a stopper section 35 at one end where the liquid inlet pipe 32 and the liquid outlet pipe 33 are provided. Specifically, the stopper section 35 and the contact portion 31 both extend downward from the bottom of the water-cooled plate 30. In this way, the stopper section 35 can be used as a stopper for inserting and positioning the water-cooled plate 30, that is, when the water-cooled plate 30 is inserted between the socket 10 and the fixed cover 20, the water-cooled plate 30 only needs to be inserted and pushed until the stopper section 35 abuts against the rear side of the socket 10 to reach the position, thereby facilitating the installer or maintenance personnel to fix the fixing portion 43 of the positioning member 40 in the fixing hole 34 of the water-cooled plate 30.

[0064] However, the positioning method of the water cooling plate 30 of the present invention is not limited to the above-mentioned method. Figures 6 to 8As shown, it is the second embodiment of the utility model. The water-cooled plate 30 in this embodiment has a protrusion 36. The protrusion 36 is arranged on the side of the water-cooled plate 30 away from the through groove 12 (that is, the top of the water-cooled plate 30). The end of the elastic arm 211 abuts against the protrusion 36. More specifically, in this embodiment, the ends of each elastic arm 211 corresponding to the water-cooled plates 30 in a group of two abut against the opposite sides of the protrusion 36, that is, the protrusion 36 is located between each elastic arm 211 in a group of two. Thereby, by each elastic arm 211 abutting against the opposite front and rear sides of the protrusion 36, the insertion direction of the water-cooled plate 30 can be restricted, so as to prevent the water-cooled plate 30 from being separated from the heat dissipation device, and there is no need to set an additional positioning member 40 as in the first embodiment.

[0065] In addition, see Figure 6 , Figure 7 and Figures 9 and 10 As shown, the fixed cover 20 may also have a track 24, and the water-cooling plate 30 has a pair of extended side panels 37. The track 24 is arranged on the side of the fixed cover 20 facing the through groove 12, and the track 24 has two opposite slide grooves 241. Each extended side panel 37 extends in opposite directions from the left and right sides of the water-cooling plate 30. Each extended side panel 37 is slidably accommodated in each slide groove 241. Thereby, by cooperating with each extended side panel 37 of the water-cooling plate 30 and each slide groove 241 of the track 24, the water-cooling plate 30 can slide stably when inserted without excessive skewness, thereby limiting the left and right sides of the water-cooling plate 30. It should be noted that although the two slide grooves 241 of the track 24 and the two extended side panels 37 of the water-cooling plate 30 are only drawn in Figures 6 to 10 In the second embodiment, it does not affect the use of the water cooling plate 30 in the aforementioned first embodiment by a person skilled in the art. That is, no matter what positioning method (positioning member 40, protrusion 36, or other methods) is used by the utility model to prevent the water cooling plate 30 from being separated from the heat dissipation device, as long as the two slide grooves 241 of the track 24 are matched with the two extended side plates 37 of the water cooling plate 30, they should still fall within the protection scope of the utility model.

[0066] The heat dissipation device of the present invention covers the plug socket 10 with a fixed cover shell 20 so that the water cooling plate 30 is located between the plug socket 10 and the fixed cover shell 20, and the elastic arm 211 of the fixed cover shell 20 extends toward the through groove 12 of the plug socket 10 to elastically abut the water cooling plate 30, so that the water cooling plate 30 can be effectively and conveniently fixed, and when the connector B is plugged into the plug chamber 11, the contact portion 31 of the water cooling plate 30 can be closely attached to the connector B for heat dissipation.

[0067] In summary, the above disclosure of the utility model is to enable those with ordinary knowledge in the field to clearly understand the technical content of the utility model and implement it accordingly, and is not intended to limit the scope of patent protection of the utility model. In addition, the utility model can of course have other unlisted embodiments. Without departing from the spirit and essence of the utility model, those familiar with the field should be able to evolve various corresponding changes and deformations based on the utility model, but these corresponding changes and deformations should all fall within the scope of protection of the patent applied for the utility model.
