Description

Technical Field

[0001] The utility model relates to a water-cooling plate and a water-cooling system, belonging to the technical field of water-cooling structures. Background Art

[0002] In the field of heat exchangers, a water-cooling plate is an important component. Its main function is to reduce the temperature of the object to be cooled (such as an electronic component) through the heat exchange between the cooling medium (such as water) and the object to be cooled, so as to ensure its normal operation.

[0003] The water-cooling pipe is encapsulated inside the water-cooling plate, and the water-cooling pipe is communicated with the cooling medium inlet and outlet arranged on the water-cooling plate. In order to prevent the leakage of the cooling medium, a sealing ring needs to be arranged at the connection between the water-cooling pipe and the cooling medium inlet and outlet. In the traditional scheme, usually a sealing groove is processed on the inner wall surface of the cooling medium inlet and outlet on the water-cooling plate, or a sealing groove is processed on the outer wall surface of the water-cooling pipe for installing the sealing ring to realize the sealing of the connection between the water-cooling pipe and the cooling medium inlet and outlet joint. However, when the size of the water-cooling plate is limited, the size of the internal water-cooling pipe is small, and the thickness of the water-cooling pipe does not meet the condition for processing the sealing groove; while processing the sealing groove on the inner wall surface of the cooling medium inlet and outlet joint, the operation is not convenient when installing the sealing ring, and if the sealing ring is not installed in place, the sealing effect will be affected. In addition, the existing water-cooling pipes usually adopt ordinary carbon steel pipes or aluminum pipes. Although the cost is low, the thermal conductivity is poor and it is easy to corrode, thus affecting the long-term use effect of the water-cooling plate.

[0004] Therefore, how to design a water-cooling plate that is easy to process and convenient to install is an urgent problem to be solved in the current field. Content of the Utility Model

[0010] As a preferred embodiment of the present utility model, a groove is formed on the lower end face of the water-cooling plate main body, and a water-cooling pipe groove for installing a water-cooling pipe is arranged in the groove; the groove is closed by a water-cooling plate bottom plate.

[0011] As a preferred embodiment of the present utility model, the water-cooling plate bottom plate is also provided with a water-cooling pipe groove; when the water-cooling plate bottom plate closes the groove on the lower end face of the water-cooling plate main body, the water-cooling pipe groove in the groove and the water-cooling pipe groove on the inner side face of the water-cooling plate bottom plate are opposite to form a complete water-cooling pipe groove.

[0012] As a preferred embodiment of the present utility model, two sealing rings A are arranged in the annular groove of the inlet and outlet connection seat, and the two sealing rings A are separated and limited by a retaining ring, and the sealing ring A located on the outer side is limited by another retaining ring.

[0013] As a preferred embodiment of the present utility model, the inlet and outlet connection seat is made of stainless steel.

[0014] As a preferred embodiment of the present utility model, a guiding groove is arranged on the upper end face of the water-cooling plate main body.

[0015] In addition, the present utility model provides a water-cooling system, including: two water-cooling pipe groups and a plurality of water-cooling plates; the two water-cooling pipe groups are respectively an inlet water-cooling pipe group and an outlet water-cooling pipe group;

[0016] The plurality of water-cooling plates are arranged at intervals in the height direction;

[0017] The water-cooling pipe group is of a segmented type and is formed by sequentially connecting a plurality of pipe joints through connectors. Adjacent water-cooling plates are connected by one pipe joint, and the pipe joint is connected to the inlet and outlet connection seat on the corresponding water-cooling plate at the joint, and then is communicated with the water-cooling pipe inside the water-cooling plate.

[0018] As a preferred embodiment of the present utility model, sealing rings B are installed on the outer side faces at both ends of the pipe joint.

[0019] As a preferred embodiment of the present utility model, adjacent pipe joints are connected by a water-cooling three-way at the position where the water-cooling plate is located; a sealing ring B is installed on the outer wall surface of the horizontal connection port of the water-cooling three-way for connecting to the inlet and outlet connection seat;

[0020] The pipe joint at the lowermost end is connected to the lowermost water-cooling plate through a water-cooling two-way, and a sealing ring B is installed on the outer wall surface of the horizontal connection port of the water-cooling two-way for connecting to the inlet and outlet connection seat;

[0021] The pipe joints at the uppermost positions in the two water-cooling pipe groups are respectively connected to the inlet water pipe and the outlet water through water-cooling right angles, wherein the inlet water pipe is connected to the inlet connector, and the outlet water pipe is connected to the outlet connector.

[0022] Beneficial effects:

[0023] (1) The water-cooling plate of the present invention has a simple overall structure, is easy to process, and is convenient to install. Specifically, an annular groove (i.e., the mid-diameter section of its center hole) is machined on the inner surface of the inlet and outlet connection seat for connecting the inner circumference of one end of the water-cooling pipe, which extends to the end face of the end face. The sealing ring A is limited by a retaining ring in the mid-diameter section. Therefore, when installing the sealing ring A, it can be directly pushed in from the end face of the inlet and outlet connection seat, which is convenient for installation. The installation process is simplified and the installation difficulty is reduced. At the same time, it is also convenient for replacing the inlet and outlet connection seat. Moreover, the retaining ring and the end face of the through hole on the water-cooling plate body cooperate with the limiting sealing ring A to ensure that the position of the sealing ring A is reliable, thereby improving the sealing effect and preventing liquid leakage.

[0024] (2) In the water-cooling plate of the present invention, the water-cooling tubes are made of copper tubes that are easy to form and have good thermal conductivity and corrosion resistance, and the inlet and outlet connection seats are made of stainless steel, so the water-cooling plate has good corrosion resistance.

[0025] (3) In the water-cooling plate of the present invention, the water-cooling pipe groove is formed by connecting the water-cooling pipe groove arranged on the bottom plate of the water-cooling plate with the water-cooling pipe groove arranged inside the water-cooling plate body, thereby enabling the water-cooling pipe to be pressed tightly into the water-cooling pipe groove through the bottom plate of the water-cooling plate, and ensuring that the water-cooling pipe fits with the water-cooling plate body and the bottom plate of the water-cooling plate.

[0026] (4) In the water-cooling system of the present invention, the water-cooling pipe group adopts a segmented type, which is easy to process and install; and because it adopts a segmented type, the size of the pipe section inserted into the joint can be used to compensate for the processing error.

[0027] (5) In the water cooling system of the present invention, the sealing rings B of the joints and joints are all located on the outer wall surface, which is easy to process and install. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0041] The following further elaborates on the present utility model in conjunction with the accompanying drawings and embodiments.

[0042] Embodiment 1:

[0043] This embodiment provides a water-cooling plate, which is easy to process and install.

[0044] As shown in Figure 1 and Figure 2 , the water-cooling plate includes: a water-cooling plate body 1, a water-cooling pipe 5 encapsulated inside the water-cooling plate body 1, and a water-cooling plate bottom plate 2 provided on the lower end surface of the water-cooling plate body 1.

[0045] A groove is formed on the lower end surface of the water-cooling plate body 1, and a water-cooling pipe groove for installing the water-cooling pipe 5 is provided in the groove. The inner side surface of the water-cooling plate bottom plate 2 is correspondingly provided with a water-cooling pipe groove; thus, when the lower end surface groove of the water-cooling plate body 1 is encapsulated by the water-cooling plate bottom plate 2, 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 2 are opposite to form a complete water-cooling pipe groove, and then the water-cooling pipe 5 is pressed tightly in the water-cooling pipe groove.

[0046] As an example, the water-cooling pipe 5 is made of red copper pipe, which is easy to form and has good thermal conductivity and corrosion resistance.

[0047] As an example, a number of weight reduction holes 19 are processed on the water-cooling plate body 1.

[0048] On the transverse sides of the rear end face of the water-cooling plate main body 1, through holes communicating with the grooves on its lower end face are provided on both sides for installing the inlet and outlet connection seats 3, and the inlet and outlet connection seats 3 are used to connect the water-cooling pipes 5 and the external water-cooling pipe group.

[0049] As Figure 3 and Figure 4 shown, a sealing ring A7 and a retaining ring 8 are installed on the inlet and outlet connection seat 3; the central hole of the inlet and outlet connection seat 3 is a stepped hole with three different diameters, namely a large-diameter section at one end, a small-diameter section in the middle, and a medium-diameter section at the other end (here, large, medium, and small are relative to each other); the large-diameter section is used to connect the external water-cooling pipe group, and the medium-diameter section is used to install the sealing ring A7 and the retaining ring 8; the small-diameter section and the medium-diameter section where the sealing ring A7 and the retaining ring 8 are installed are used to sealingly connect the water-cooling pipe 5 inside the water-cooling plate main body 1.

[0050] For the inlet and outlet connection seat 3 adopting this structural form, when installing the sealing ring A7, it is only necessary to sequentially insert the sealing ring A7 and the retaining ring 8 into the medium-diameter section of the inlet and outlet connection seat 3 from the end of the medium-diameter section of the inlet and outlet connection seat 3; then install the inlet and outlet connection seat 3 into the corresponding through hole on the water-cooling plate main body 1 (as Figure 3 shown, the axial limit of the retaining ring 8 at the end is carried out by the inner bottom surface of this through hole); finally, the inlet and outlet connection seat 3 is fixed to the water-cooling plate main body 1 through the threaded holes on both sides; the inlet and outlet connection seat 3 of this structural form can facilitate installation while ensuring sealing.

[0051] As an example, two sealing rings A7 are provided in the medium-diameter section of the inlet and outlet connection seat 3, thus forming two seals. The two sealing rings A7 are separated and limited by the retaining ring 8, and the retaining ring 8 located on the outermost side is limited by the end face of the through hole on the water-cooling plate main body 1.

[0052] As an example, the inlet and outlet connection seat 3 is made of stainless steel.

[0053] Therefore, when assembling the water-cooling plate, first sequentially install the sealing ring A7 and the retaining ring 8 into the medium-diameter section of the inlet and outlet connection seat 3 (it can be directly pushed in from the end face of the medium-diameter section of the inlet and outlet connection seat 3, which is convenient for installation); then install the bent water-cooling pipe 5 into the water-cooling pipe groove on the water-cooling plate main body 1, and then install the two inlet and outlet connection seats 3 into the through holes at the corresponding positions on the water-cooling plate main body 1 respectively. The two ends of the water-cooling pipe 5 are respectively inserted into the inlet and outlet connection seats 3 on the corresponding sides (at this time, the outer wall surface of the water-cooling pipe 5 squeezes the sealing ring A7 to achieve sealing), then fix the inlet and outlet connection seat 3 and the water-cooling plate main body 1 through screws, and finally fix the water-cooling plate bottom plate 2 and the water-cooling plate main body 1 through screws, so that the water-cooling pipe 5 is pressed into the corresponding slot and ensure its fit with the water-cooling plate main body 1 and the water-cooling plate bottom plate 2.

[0054] The water-cooled plate with this structural form is easy to process and convenient to install. Moreover, the water-cooled pipe 5 is made of red copper pipe which is easy to form and has good thermal conductivity and corrosion resistance, and the inlet and outlet connection seats 3 are made of stainless steel. Therefore, this water-cooled plate has good corrosion resistance.

[0055] As an example, as Figure 5 shown, a guiding groove 6 is provided on the upper end face of the water-cooled plate body 1 for guiding when installing a reinforcement machine on the water-cooled plate.

[0056] Embodiment 2:

[0057] This embodiment provides a cabinet water-cooling system.

[0058] As Figure 6 and Figure 7 shown, where Figure 7 is a layout schematic diagram of this water-cooling system in the cabinet; this water-cooling system includes: two water-cooled pipe groups and several water-cooled plates 100; the water-cooled plate 100 is the water-cooled plate in the above-mentioned Embodiment 1; the two water-cooled pipe groups are respectively used as the inlet water-cooled pipe group 13 and the outlet water-cooled pipe group 17.

[0059] In this water-cooling system, a plurality of water-cooled plates 100 are arranged at intervals in the height direction; the water-cooled pipe groups provide cooling water for the above-mentioned plurality of water-cooled plates 100. Based on this, the water-cooled pipe groups are of a segmented type and are formed by sequentially connecting several pipe joints 11 through connectors. As an example, adjacent water-cooled plates 100 are connected by one pipe joint 11, and the pipe joint 11 at the uppermost position is connected to the inlet connector 15 or the outlet connector 16; the inlet connector 15 and the outlet connector 16 are respectively connected to an external water-cooling system.

[0060] As Figure 12 shown, the pipe joint 11 selects a stainless steel pipe with a corresponding specification according to the required pipe diameter, and groove positions for installing the sealing ring B18 are processed on the outer side surfaces at both ends of the stainless steel pipe.

[0061] Adjacent pipe joints 11 are connected by a water-cooled three-way 12 at the position where the water-cooled plate 100 is located; the pipe joint 11 at the lowermost end is connected to the water-cooled plate 100 at the lowermost layer through a water-cooled two-way 10; thus, a parallel structure is formed among the water-cooled plates 100.

[0062] As Figure 9As shown, the water-cooled three-way joint 12 has vertically penetrating upper and lower connection ports and a laterally penetrating lateral connection port. A sealing ring B18 is installed in a groove on the outer wall surface of the lateral connection port and inserted into the large-diameter section of the inlet and outlet connection seat 3 of the water-cooled plate 100, thereby achieving communication with the internal water-cooled pipe 5 of the water-cooled plate 100. The upper and lower connection ports are respectively used for plugging the pipe joints 11 at the upper and lower ends (that is, the ends of the pipe joints 11 are inserted into the corresponding connection ports. Since sealing rings B18 are provided at both ends of the pipe joints 11, there is no need to provide sealing rings B18 on the inner wall surfaces of the upper and lower connection ports), as Figure 8 shown.

[0063] As Figure 10 shown, the water-cooled two-way joint 10 has an upper connection port and a lateral connection port. A sealing ring B18 is installed in a groove on the outer wall surface of the lateral connection port and inserted into the large-diameter section of the inlet and outlet connection seat 3 of the water-cooled plate 100, thereby achieving communication with the internal water-cooled pipe 5 of the water-cooled plate 100. The upper connection port is used for plugging the pipe joint 11 above it.

[0064] The pipe joints 11 at the uppermost positions in the two water-cooled pipe groups are respectively connected to the water inlet pipeline and the water outlet through the water-cooled right-angle joint 14. The water inlet pipeline is connected to the water inlet joint 15, and the water outlet pipeline is connected to the water outlet joint 16. According to the positions of the water inlet joint 15 and the water outlet joint 16, the water inlet pipeline or the water outlet connection can also be formed by connecting several pipe joints 11. As Figure 11 shown, the water-cooled right-angle joint 14 has an upper connection port and a lateral connection port for plugging the pipe joint 11 (since sealing rings B18 are provided at both ends of the pipe joint 11, there is no need to provide a sealing ring B18 at the interface of the water-cooled right-angle joint 14).

[0065] Although the present invention has been described in detail above with general descriptions and specific embodiments, on the basis of the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
