Description

[0002] With the rapid development of the chip industry, the integration and heat generation power of power amplifier cabinets are getting higher and higher. Traditional heat extraction can no longer solve the heat dissipation problems caused by the increasing heat generation power and the increasingly narrow heat dissipation space. Therefore, water cooling is needed to dissipate heat from the power amplifier cabinet. In the water cooling method, the heat generated by the electronic equipment is transferred to the external heat dissipation device through the water cooling medium, thereby realizing the heat dissipation of the electronic equipment.

DETAILED DESCRIPTION

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0045] Embodiment 1:

[0046] The present embodiment provides a water-cooling cabinet with an independent water-cooling heat dissipation unit. Inside the water-cooling cabinet, the extension and the water-cooling plate in the water-cooling heat dissipation unit adopt a split structure, so that the water-cooling heat dissipation unit is independent of the extension. Therefore, when disassembling the extension, the water-cooling plate does not involve disassembly and assembly, thereby avoiding the hidden danger of leakage of the water-cooling heat dissipation unit; and it has a good vibration isolation and impact effect.

[0047] like Figure 1 As shown, the water-cooling cabinet includes: a main box body 2, a plurality of extensions 3 arranged side by side along the height direction inside the main box body 2, and a water-cooling heat dissipation unit arranged inside the main box body 2; wherein the water-cooling heat dissipation unit includes: two water-cooling pipe groups and water-cooling plates 4 corresponding to the extensions 3 one by one; cooling water is provided to the water-cooling plates 4 through the two water-cooling pipe groups; wherein the extensions 3 are limited at the upper end surface of the water-cooling plates 4 corresponding thereto.

[0048] As an example, four extensions 3 are arranged side by side in the height direction in the main box 2; a water-cooling plate 4 is arranged under each extension 3; that is, in the water-cooling cabinet, the extension 3 and the water-cooling plate 4 adopt a split structure (in the traditional solution, the bottom plate of the extension 3 is directly used as the water-cooling plate 4); therefore, when disassembling the extension 3, the disassembly and assembly of the water-cooling plate 4 is not involved, which can effectively avoid the risk of leakage.

[0049] like Figure 3 As shown, the main box body 2 is a cubic structure formed by processing and welding plates, and the plates include four side plates 201, a top plate 202, a rear plate 203 and a bottom plate 204; the front opening of the main box body 2 is closed by an openable front cover plate (not shown in the figure). Positioning holes are opened on the above-mentioned plates for positioning before welding, that is, before welding, the positions of the plates are fixed with positioning screws matched with the positioning holes, so as to ensure the size of the main box body 2 and reduce the deformation degree of the main box body 2 during the welding process. This processing method can effectively control the size and weight of the box body.

[0050] Vibration isolators 1 are provided at the top and bottom of the main box 2; as an example, the vibration isolators 1 are as follows: Figure 2 The GBG type wall-mounted vibration isolator shown is suitable for wall-mounted electronic equipment in strong impact environment conditions at sea. As an example, two vibration isolators 1 are arranged on the top and bottom of the main box 2 in the lateral direction.

[0051] In order to facilitate the disassembly of the vibration isolator 1 and reduce the impact of the installation of the vibration isolator 1 on the overall cabinet, the vibration isolator 1 is installed in the following manner: L-shaped vibration isolator mounting seats 101 are provided at the top and bottom of the rear end surface of the main box body 2, the horizontal portion of the L-shaped vibration isolator mounting seat 101 is fixed to the top surface (or bottom surface) of the main box body 2 by fasteners (connected by fasteners to make it detachable), and the vertical portion is used to install the vibration isolator mounting seat 101. The installation positions of the two vibration isolators 1 at the top of the rear end surface of the main box body 2 are provided with L-shaped notches to provide vibration isolation buffer space for the vibration isolator 1, that is, after the vibration isolator 1 is installed through the vibration isolator mounting seat 101, the vibration isolator 1 is located above the L-shaped notch.

[0052] like Figure 4 and Figure 5 As shown, the extension 3 includes an extension housing 301, and two guide rails 302 are arranged in parallel along the horizontal direction on the lower end surface of the extension housing 301, which are used to be connected with the water cooling plate guide groove 403 (as shown in FIG. Figure 7 The extension 3 is provided with a connector mounting plate 303 on one side of the front end face of the extension 3 for mounting the connector. The connector of the extension 3 is designed on the front end face of the extension 3. This structure facilitates the plugging and unplugging of the connector and reduces the space required for wiring.

[0053] The water cooling unit is used to cool each extension 3 inside the cabinet. The layout of the water cooling unit inside the cabinet is as follows: Figure 6 As shown; the two water-cooling pipe groups in the water-cooling heat dissipation unit are respectively the inlet water-cooling pipe group 6 and the outlet water-cooling pipe group 7.

[0054] In this embodiment, in view of the fact that four extensions 3 are provided, four water-cooled plates 4 are arranged at intervals along the height direction in the water-cooled heat dissipation unit; cooling water is provided to the above four water-cooled plates 4 through a water-cooled pipe group. Based on this, the water-cooled pipe group (including the water-inlet water-cooled pipe group 6 and the water-outlet water-cooled pipe group 7) adopts a segmented type, which is formed by a plurality of pipe sections 8 connected in sequence through joints. As an example, adjacent water-cooled plates 4 are connected through a pipe section 8, the uppermost pipe section 8 in the water-inlet water-cooled pipe group 6 is connected to the water-inlet joint 12, and the uppermost pipe section 8 in the water-outlet water-cooled pipe group 7 is connected to the water-outlet joint 13. The water-inlet joint 12 and the water-outlet joint 13 are respectively connected to the external water cooling system. As a result, in the water-cooled heat dissipation unit, each water-cooled plate 4 forms a parallel structure.

[0055] As an example, the water inlet joint 12 and the water outlet joint 13 are arranged in the middle position on the top plate 202 of the main box body 2, and the water inlet water cooling pipe group 6 and the water outlet water cooling pipe group 7 are symmetrically arranged on both sides of the main box body 2.

[0056] like Figure 7 and Figure 8As shown, the water-cooled plate 4 includes: a water-cooled plate body 401 and a water-cooled tube 402 encapsulated inside the water-cooled plate body 401. Through holes communicating with the grooves on the lower end surface of the water-cooled plate body 401 are provided on both sides of the rear end surface thereof for installing an inlet and outlet connection seat 404, which is used for sealingly connecting the water-cooled tube 402 and the water-cooled tube group.

[0057] As an example, a groove is provided on the lower end surface of the water-cooling plate body 401, and a water-cooling pipe groove is provided in the groove for installing the water-cooling pipe 402. The groove on the lower end surface of the water-cooling plate body 401 is encapsulated by the water-cooling plate bottom plate (not shown in the figure), and then the water-cooling pipe 402 is encapsulated inside the water-cooling plate body 401.

[0058] As another example, a groove is provided on the lower end surface of the water-cooling plate main body 401, and a water-cooling pipe groove is also provided on the inner side surface of the water-cooling plate bottom plate accordingly; when the groove on the lower end surface of the water-cooling plate main body 401 is encapsulated by the water-cooling plate bottom plate, the water-cooling pipe groove in the groove and the water-cooling pipe groove on the inner side surface of the water-cooling plate bottom plate form a complete water-cooling pipe groove relative to each other, thereby pressing the water-cooling pipe 402 into the water-cooling pipe groove.

[0059] As an example, the water cooling tube 402 is a copper tube that is easy to shape and has good thermal conductivity and corrosion resistance.

[0060] In the water-cooling pipe group, adjacent pipe sections 8 are connected at the location of the water-cooling plate 4 through water-cooling tees 9, and the pipe section 8 at the lowest end is connected to the water-cooling plate 4 at the lowest layer through water-cooling two-way 10. As an example, the pipe section 8 selects a stainless steel pipe of corresponding specifications according to the required pipe diameter, and sealing rings are installed on the outer sides of both ends of the stainless steel pipe.

[0061] The water-cooling tee 9 has a vertically penetrating upper and lower connection ports and a transverse connection port penetrating on one side, wherein the outer wall surface of the transverse connection port is installed with a sealing ring, which is inserted into the inlet and outlet connection seat 404 of the water-cooling plate 4, thereby realizing the connection with the water-cooling pipe 402 inside the water-cooling plate 4; the upper and lower connection ports are respectively used to plug the pipe segments 8 at the upper and lower ends (that is, the ends of the pipe segments 8 are inserted into the connection ports at the corresponding positions, and since the outer wall surfaces of both ends of the pipe segments 8 have sealing rings, there is no need to set sealing rings on the inner wall surfaces of the upper and lower connection ports). The water-cooling two-way 10 has an upper connection port and a transverse connection port, wherein the outer wall surface of the transverse connection port is installed with a sealing ring, which is inserted into the inlet and outlet connection seat 404 of the water-cooling plate 4, thereby realizing the connection with the water-cooling pipe 402 inside the water-cooling plate 4; the upper connection port is used to plug the pipe segment 8 above it.

[0062] The uppermost pipe section 8 in the two water-cooling pipe groups is connected to the water inlet pipeline and the water outlet pipeline through the water-cooling right angle 11, wherein the water inlet pipeline is connected to the water inlet joint 12, and the water outlet pipeline is connected to the water outlet joint 13; according to the positions of the water inlet joint 12 and the water outlet joint 13, the water inlet pipeline or the water outlet connection can also be formed by connecting several pipe sections 8. The water-cooling right angle 11 has an upper connection port and a transverse connection port for inserting the pipe section 8 (since the outer wall surfaces at both ends of the pipe section 8 have sealing rings, it is not necessary to set sealing rings on the inner wall surfaces of the upper and lower connection ports).

[0063] Embodiment 2:

[0064] On the basis of the above-mentioned embodiment 1, the extension 3 is limited on the upper end surface of the corresponding water-cooling plate 4 by the clamping assembly 5. This embodiment further defines the clamping assembly 5.

[0065] In this embodiment, the clamping assembly 5 adopts a wedge screw clamping assembly, and the extension 3 is limited on the corresponding water cooling plate 4 inside the main box 2 by the clamping assembly 5, which facilitates the installation and replacement of the extension 3.

[0066] like Figure 4 and Figure 7 As shown, a clamping assembly 5 is provided on both lateral sides of the water cooling plate 4. Figure 5 As shown, in the corresponding extension 3 , the extension box body 301 has two lateral sides extending outward from the bottom plate to form limiting bosses 304 for cooperating with the clamping assembly 5 .

[0067] like Fig.10 The clamping assembly 5 includes: a support seat 506 and a wedge block 501, a wedge seat 503, a long rod screw 504 and a wedge nut 505 installed on the support seat 506; wherein the support seat 506 is arranged on the water-cooling plate 4, and is arranged along the longitudinal direction of the water-cooling plate 4 (i.e., the depth direction of the cabinet). In this example, the support seat 506 is an inverted L-shape, the vertical part is fixedly connected to the water-cooling plate, and the lower end surface of the horizontal part is used to set the wedge seat 503 and the wedge block 501, specifically:

[0068] The wedge-shaped seat 503 is arranged on the lower end surface of the horizontal part of the support seat 506 (usually formed as one piece with the support seat 506), the front and rear end surfaces of the wedge seat 503 are wedge-shaped surfaces (i.e., inclined surfaces inclined inwardly), and the long rod screw 504 passes through the wedge seat 503 from front to back; the front end of the long rod screw 504 extends out of the wedge seat 503 and is connected to the wedge block 501 (i.e., the wedge block 501 is coaxially sleeved on the optical axis part of the long rod screw 504), and the wedge block 501 cooperates with the wedge surface of the corresponding end of the wedge seat 503; the rear end of the long rod screw 504 extends out of the wedge seat 503 and is connected to the wedge nut 505 through threads, and the wedge nut 505 cooperates with the wedge surface of the corresponding end of the wedge seat 503; the front end of the long rod screw 504 is provided with a nut, which contacts the end surface of the front end wedge block 501; the wedge seat 503 is provided with a groove for moving the long rod screw 504 up and down.

[0069] When the extension 3 is placed on the upper end surface of the water-cooled plate 4, the limiting bosses 304 at the two lateral ends of the extension 3 are located below the corresponding side clamping assembly 5 (i.e. below the wedge-shaped seat 503 and the wedge block 501); by screwing the long rod screw 504 at the nut, the wedge block 501 and the wedge nut 505 can be moved along the wedge-shaped surface of the wedge seat 503 (moving inward and downward, during the movement, the long rod screw 504 follows the wedge block 501 and the wedge nut 505 to move in the groove of the wedge seat 503), so that the lower end surface of the wedge block 501 and the wedge nut 505 presses the limiting boss 304 on the extension 3 (at this time, the lower end surfaces of the wedge block 501 and the wedge nut 505 protrude from the lower end surface of the wedge seat 503), thereby achieving the limitation of the extension 3 (i.e. pressing the extension 3 onto the water-cooled plate 4).

[0070] Since the wedge block 501, the wedge nut 505 and the long rod screw 504 can move as a whole in the groove of the wedge seat 503, in order to avoid the wedge block 501, the wedge nut 505 and the long rod screw 504 moving downward when installing the extension 3, affecting the installation of the extension 3 (initially, it is necessary to ensure that the lower end surface of the wedge block 501 and the wedge nut 505 is flush with the lower end surface of the wedge seat 503 to ensure that the extension 3 can be installed smoothly); a spring piece 502 is provided in the groove of the wedge seat 503, and the spring piece 502 is located in the groove of the wedge seat 503. The horizontal portion between the bottom surface of the groove and the long rod screw 504, that is, the middle portion of the spring piece 502 is fixedly connected to the bottom surface of the groove of the wedge seat 503 by rivets, and the upward bent portions at the front and rear ends press the long rod screw 504 upward, thereby pressing the upper end surface of the wedge block 501 and the wedge nut 505 to the horizontal portion of the support seat 506 to prevent the wedge block 501, the wedge nut 505 and the long rod screw 504 from shaking up and down (the spring piece 502 is compressed during the movement and pressing process of the wedge block 501 and the wedge nut 505 along the wedge surface of the wedge seat 503).

[0071] The wedge screw clamping assembly is used to replace the traditional pin shaft slide rail structure, which simplifies the structure and reduces the matching requirements, optimizes the assembly process, and is easier to install.

[0072] As an example, in order to further ensure the reliability of the cabinet, the extension 3 and the water cooling plate 4 are further fixed together by fasteners, such as Figure 5 As shown, the front end of the guide rail 302 on the lower end face of the extension 3 has a downward extension portion, on which a fastening hole is provided, and the corresponding front end face of the water-cooled plate 4 is provided with a fastening hole that matches therewith, thereby further fixing the extension 3 and the water-cooled plate 4 by fasteners (such as screws) that match the two fastening holes.

[0073] Embodiment 3:

[0074] On the basis of the above-mentioned Embodiment 1 and Embodiment 2, this embodiment provides a specific implementation method of the inlet and outlet connection seat 404 in the water cooling plate 4.

[0075] like Figure 8 and Fig. 9 As shown, the center hole of the inlet and outlet connection seat 404 is a stepped hole, the large diameter section is used to connect the water cooling pipe group, and the small diameter section is used to connect the water cooling pipe 402. In order to ensure sealing and facilitate installation, an annular groove is processed on the inner circumference of the small diameter section of the inlet and outlet connection seat 404 away from the end where the large diameter section is located; the annular groove extends to the end face of the small diameter section of the inlet and outlet connection seat 404, thereby further forming a stepped hole in the center hole of the small diameter section; thus, the center hole of the inlet and outlet connection seat 404 is divided into three sections, namely the large diameter section, the small diameter section and the medium diameter section (annular groove part); the "large", "medium" and "small" here are relative to the three.

[0076] The middle diameter section of the inlet and outlet connection seat 404 is used to install the sealing ring 4041 and the retaining ring 4042, that is, the sealing ring 4041 is limited in the inlet and outlet connection seat 404 by the retaining ring 4042. As an example, the annular groove is provided with two sealing rings 4041, and the two sealing rings 4041 are separated and limited by the retaining ring 4042. The outer side of the sealing ring 4041 located on the outside is limited by another retaining ring 4042, and the outermost retaining ring 4042 is limited by the inner bottom surface of the through hole at the corresponding position on the water-cooling plate 4 (the through hole for installing the inlet and outlet connection seat 404).

[0077] Therefore, when assembling the water-cooled plate 4, first install the sealing ring 4041 and the retaining ring 4042 in the middle diameter section of the inlet and outlet connection seat 404 in sequence (just push it in from the end face of the middle diameter section of the inlet and outlet connection seat 404, which is easy to install); then install the two inlet and outlet connection seats 404 into the through holes at the corresponding positions on the water-cooled plate body 401 respectively. Install the bent water-cooled pipe 402 into the water-cooled pipe groove on the water-cooled plate body 401, and then install the two ends of the water-cooled pipe 402 into the inlet and outlet connection seats 404 on both sides respectively (at this time, the outer wall of the water-cooled pipe 402 squeezes the sealing ring 4041 to achieve sealing), and finally fix the water-cooled plate bottom plate and the water-cooled plate body 401 with screws, so that the water-cooled pipe 402 is pressed into the corresponding slot, and ensures that it fits with the water-cooled plate body 401 and the water-cooled plate bottom plate.

[0078] As an example, the inlet and outlet connection seats 404 are made of stainless steel.

[0079] The water cooling plate 4 of this structural form is easy to process and install.

[0080] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
