Description

Technical Field

[0002] Due to its physical properties, water is not better than metal in thermal conductivity, but flowing water has excellent thermal conductivity, that is, the heat dissipation performance of the water-cooled radiator is proportional to the flow rate of the cooling liquid (water or other liquid), and the flow rate of the cooling liquid is related to the power of the cooling system water pump. In addition, water has a large heat capacity, which makes the water-cooled refrigeration system have a good heat load capacity.

[0003] The prior art patent with announcement number 37N217735994U discloses a copper tube embedded water-cooled radiator, including a mounting bottom frame, a heat exchange box is arranged on the front side of the mounting bottom frame, the heat exchange box is provided with inclined and evenly arranged mounting holes, a protective tube is installed between the inner walls of the heat exchange box corresponding to the mounting holes, a coolant pipe is installed on the heat exchange box through the protective tube, a fan rear frame is embedded in the middle of the rear side of the fan frame, and a fan is fixedly installed in the middle of the front side of the fan rear frame. During the use of the utility model, the contact area between the copper tube in the radiator and the object to be cooled can be effectively increased, thereby achieving the purpose of increasing the cooling area, accelerating the cooling efficiency, and facilitating use.

[0004] When the radiator is in use, it is fixed on an external device by multiple sets of fixing bolts. The radiator mainly dissipates heat by multiple sets of heat sinks in conjunction with copper tube water cooling.

[0054] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0055] Embodiment 1:

[0056] like Figures 1 to 4 As shown, the utility model provides a copper tube embedded water cooling radiator, comprising: a mounting member 1 for connecting the radiator with an external device, a fixing plate 2 movably arranged above the mounting member 1 for fixing the radiator, and an adjusting component 3 arranged on the mounting member 1 for adjusting the fixing plate 2;

[0057] The mounting member 1 is mounted on an external device. When the radiator needs to be repaired and dust cleaned, the mounting member 1 does not need to be repeatedly disassembled and assembled. The heat dissipation component 4 can be fixed by the fixing plate 2, which is convenient for fixing and disassembling the heat dissipation component 4. The operation is relatively convenient. By adjusting the setting of the adjustment component 3, the positions of the two fixing plates 2 can be adjusted to fix the heat dissipation component 4 or release the heat dissipation component 4.

[0058] Specifically, the mounting member 1 includes a mounting plate 11 for supporting the mechanism, a mounting block 12 fixedly mounted on the mounting member 1 for connecting, and a mounting bolt 13 plugged into the mounting block 12 for mounting the mounting plate 11, and the mounting bolt 13 is threadedly connected to the mounting block 12;

[0059] When in use, the mounting bolts 13 can be mounted on the external device through the mounting plate 11 and the mounting block 12, so as to connect the external device and the radiator.

[0060] In one embodiment, specifically, the adjustment assembly 3 includes a shelf plate 31 movably arranged above the mounting member 1, a rotating rod 32 arranged at the bottom of the shelf plate 31, and an extrusion block 33 arranged below the shelf plate 31, wherein the other end of the rotating rod 32 is rotatably mounted on the extrusion block 33, and the number of the extrusion blocks 33 is two;

[0061] When the heat dissipation component 4 is placed on the adjustment component 3, under the action of gravity of the heat dissipation component 4, the shelf plate 31 will move downward, and the downward movement of the shelf plate 31 will drive the rotating rod 32 to rotate. The rotation of the two rotating rods 32 will make the two fixed plates 2 move away from each other, and the rotating rod 32 will also drive the two extrusion blocks 33 to approach each other. The two extrusion blocks 33 approaching each other will squeeze the transverse fixing spring 34, and under the action of the spring force of the transverse fixing spring 34, the two fixing plates 2 will fix the heat dissipation component 4 on the shelf plate 31, so that the heat dissipation component 4 can be installed. When the heat dissipation component 4 needs to be removed, it is only necessary to press the shelf plate 31 downward so that the two fixing plates 2 are no longer in contact with the heat dissipation component 4, and the heat dissipation component 4 can be directly taken down, which is convenient for the disassembly and assembly of the heat dissipation component 4 and the maintenance and cleaning of the heat dissipation component 4.

[0062] In one embodiment, further, the adjustment assembly 3 further includes a guide frame 35, the guide frame 35 is fixedly mounted on the mounting plate 11; a guide sleeve 36, the guide sleeve 36 is fixedly mounted on the extrusion block 33, and the guide sleeve 36 is slidably sleeved on the guide frame 35;

[0064] Specifically, the adjustment assembly 3 further includes a telescopic rod 37, one end of which is fixedly mounted on the bottom of the shelf board 31, and the other end of the telescopic rod 37 is fixedly mounted on the mounting member 1, and a longitudinal fixing spring 38 is sleeved on the telescopic rod 37, one end of the longitudinal fixing spring 38 is fixedly mounted on the telescopic rod 37, and the other end of the longitudinal fixing spring 38 is fixedly mounted on the bottom of the shelf board 31;

[0065] On the other hand, when the shelf plate 31 moves downward, the longitudinal fixing spring 38 can also be compressed. The spring force of the longitudinal fixing spring 38 can further enhance the fixing effect of the two fixing plates 2 on the heat dissipation component 4. By setting the telescopic rod 37, the stability of the downward movement of the shelf plate 31 can be enhanced, and the longitudinal fixing spring 38 can be prevented from being skewed.

[0066] Specifically, the adjustment assembly 3 further includes a cross-shaped slide groove 39 provided on the shelf plate 31 and a cross-shaped slider 310 installed at the bottom of the fixed plate 2, and the cross-shaped slider 310 is slidably installed in the cross-shaped slide groove 39;

[0067] By setting the cross-shaped slide groove 39 and the cross-shaped slider 310 , the cross-shaped slider 310 slides in the cross-shaped slide groove 39 to support and guide the fixed plate 2 , so that the fixed plate 2 can only slide left and right on the shelf plate 31 .

[0068] Embodiment 2:

[0069] Reference Figure 1-Figure 4 On the basis of the first embodiment, the heat dissipation component 4 can be provided to dissipate heat for external devices.

[0070] Specifically, the heat dissipation assembly 4 includes a housing 41 fixedly mounted on the shelf 31, multiple groups of heat dissipation fins 42 fixedly mounted in the mounting member 1, and a heat conducting plate 43 mounted on the multiple groups of heat dissipation fins 42, and the multiple groups of heat dissipation fins 42 are all inlaid with copper tubes 44;

[0071] The copper tubes 44 are distributed in an S shape within the plurality of heat dissipation fins 42;

[0072] The heat conducting plate 43 is in direct contact with the external device, and the heat generated by the external device will be transferred to the multiple groups of heat dissipation fins 42 through the heat conducting plate 43. On the one hand, the multiple groups of heat dissipation fins 42 are in contact with the air to increase the heat dissipation area and enhance the heat dissipation effect on the external device. On the other hand, the cooling water flowing in the copper tube 44 can take away the heat on the heat dissipation fins 42, thereby achieving a better heat dissipation effect on the external device.

[0073] Specifically, the heat dissipation assembly 4 further includes a cooling water tank 45, which is fixedly mounted on one side of the housing 41. The starting end of the copper tube 44 is located in the cooling water tank 45. A delivery pump 46 is also arranged in the cooling water tank 45. The starting end of the copper tube 44 is fixedly connected to the output end of the delivery pump 46. The input end of the delivery pump 46 is connected to a first pumping pipe 47.

[0074] The delivery pump 46 pumps the cooling water in the cooling water tank 45 into the copper tube 44 through the first pumping pipe 47 . The cooling water in the copper tube 44 can take away the heat on the heat dissipation fins 42 during the flow.

[0075] Specifically, the heat dissipation assembly 4 further includes a cooling water tank 45, which is fixedly mounted on one side of the housing 41, and the starting end of the copper tube 44 is located in the cooling water tank 45; a delivery pump 46, which is fixedly mounted in the cooling water tank 45, and the starting end of the copper tube 44 is fixedly connected to the output end of the delivery pump 46; a first pumping pipe 47, which is fixedly mounted on the input end of the delivery pump 46;

[0076] The cooling water flowing in the copper tube 44 will eventually enter the heat dissipation water tank 48 for heat dissipation. The cooling water after heat dissipation will be pumped into the return pipe 411 through the second pumping pipe 410 by the return pump 49, and then returned to the cooling water tank 45 through the return pipe 411, thereby achieving the effect of cooling water circulation.

[0077] Working principle: When in use, the mounting plate 11 is fixed to the external device through the mounting block 12 and the mounting bolts 13, and then the heat dissipation component 4 is placed on the shelf plate 31, and the heat conduction plate 43 is pressed against the external device. Under the gravity of the heat dissipation component 4, the shelf plate 31 will move downward, and the downward movement of the shelf plate 31 will drive the rotating rod 32 to rotate. The rotation of the two rotating rods 32 will cause the two fixed plates 2 to move away from each other, and the rotating rod 32 will also drive the two extrusion blocks 33 to move closer to each other. The two extrusion blocks 33 approaching each other will cause the transverse fixing spring 34 to be squeezed, and the transverse fixing spring 34 will be squeezed. The spring force of the fixed spring 34 causes the two fixing plates 2 to fix the heat dissipation component 4 on the shelf plate 31, so that the heat dissipation component 4 can be fixed. When the shelf plate 31 moves downward, the longitudinal fixing spring 38 can also be compressed. Under the spring force of the longitudinal fixing spring 38, the fixing effect of the two fixing plates 2 on the heat dissipation component 4 can be further improved. The setting of the telescopic rod 37 can improve the stability of the shelf plate 31 moving downward and prevent the longitudinal fixing spring 38 from being skewed. When the heat dissipation component 4 needs to be removed, it is only necessary to press the shelf plate 31 downward to make the two fixing plates 2 move downward. The fixed plate 2 is no longer in contact with the heat dissipation component 4, and the heat dissipation component 4 can be directly taken down, which is convenient for the disassembly and assembly of the heat dissipation component 4, and is convenient for the maintenance and cleaning of the heat dissipation component 4. When the external device needs to be cooled, an appropriate amount of cooling water is added to the cooling water tank 45 through the water filling pipe on the cooling water tank 45. On the one hand, the heat conduction plate 43 is directly in contact with the external device, and the heat generated by the external device will be transferred to the multiple groups of heat dissipation fins 42 through the heat conduction plate 43. On the one hand, the multiple groups of heat dissipation fins 42 are in contact with the air to increase the heat dissipation area and improve the heat dissipation effect of the external device. On the other hand, On the one hand, the delivery pump 46 will pump the cooling water in the cooling water tank 45 into the copper tube 44 through the first pumping pipe 47. The cooling water in the copper tube 44 can take away the heat on the cooling fins 42 during the flow, which has a better heat dissipation effect on the external device. The cooling water flowing in the copper tube 44 will eventually enter the cooling water tank 48 for heat dissipation. The cooling water after heat dissipation will be pumped into the return pipe 411 through the second pumping pipe 410 under the action of the return pump 49, and then returned to the cooling water tank 45 through the return pipe 411 for recycling.
