Description

Technical Field

[0001] The present invention relates to the technical field of liquid cooling plates, and in particular to a high-heat dissipation vehicle-mounted domain control liquid cooling plate. Background Art

[0002] In the traditional liquid cooling plate design, the coolant achieves efficient heat dissipation of automotive electronic components by flowing in the cooling plate. The basic principle is that the coolant flows in from the liquid inlet at one end of the cooling plate, exchanges heat with the electronic components through the internal flow channel system, and then flows out from the liquid outlet at the other end. Although this can provide a good heat dissipation effect to ensure that the electronic components are within a suitable operating temperature range, during the use of this liquid cooling plate, the coolant is continuously heated by the electronic components during the flow process, resulting in a temperature difference between the head and tail ends of the liquid, that is, the temperature of the coolant is low when it just enters the cooling plate, and its temperature will gradually increase as it flows toward the liquid outlet. Even when it reaches the liquid outlet, its temperature may be much higher than the temperature when it just enters the flow channel, which will affect the cooling efficiency and uniformity of the entire liquid cooling plate, making the temperature distribution of the electronic components uneven, thereby affecting the overall heat dissipation performance of the electronic system.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] To solve the problem of uneven cooling effect caused by large temperature difference between the coolant inlet and outlet of traditional liquid cooling plates, please refer to Figure 1-Figure 7 The present invention provides a high heat dissipation vehicle-mounted domain control liquid cooling plate, which can effectively reduce the temperature difference of the coolant at the liquid inlet and the liquid outlet, and optimize the cooling performance of the liquid cooling plate. The domain control liquid cooling plate is based on a liquid cooling plate body 1 with an S-shaped flow channel 101 opened inside. Both ends of the flow channel 101 are connected and installed with liquid inlets 2. The two liquid inlets 2 are arranged on the same side, and the middle part of the flow channel 101 is connected and installed with a liquid outlet 3. The liquid outlet 3 is arranged on the side facing away from the liquid inlet 2. The two liquid inlets 2 can synchronously transport coolant into the flow channel 101, and the coolant converges to the liquid outlet 3 and flows out. In this way, the flow path of the coolant can be reduced by half, thereby preliminarily reducing the temperature difference between the beginning and the end of the coolant.

[0038] Although shortening the path of the coolant can reduce the temperature difference, as the coolant flows in the flow channel 101, the coolant will still gradually absorb heat and become hotter, resulting in the coolant temperature at the liquid outlet 3 still being higher than the coolant temperature at the liquid inlet 2, affecting the cooling effect of the middle position of the liquid cooling plate body 1. In order to solve this technical problem, a cooling mechanism 4 for cooling the coolant in the middle of the flow channel 101 is provided at the bottom of the liquid cooling plate body 1, and the cooling mechanism 4 is configured as a frame 41 fixedly installed at the center of the bottom of the liquid cooling plate body 1, and cooling cotton 42 for absorbing the coolant is installed inside the frame 41, and guide grooves 43 for the coolant to flow into the cooling cotton 42 are provided on both sides of the interior of the frame 41, and separation Flow tube 44, one end of the shunt tube 44 is connected with the guide groove 43, and the other end of the shunt tube 44 is connected with the liquid inlet 2. When the coolant is transported from the liquid inlet 2 to the flow channel 101, a small part of the coolant will enter the shunt tube 44, and the coolant can enter the guide groove 43 along the shunt tube 44 and be absorbed by the cooling cotton 42. The cooling cotton 42 can be gradually soaked by the coolant, and the top of the cooling cotton 42 is in contact with the bottom of the liquid cooling plate body 1. The coolant absorbed by the cooling cotton 42 can locally cool the liquid cooling plate body 1, thereby reducing the temperature of the coolant in the flow channel 101, further reducing the temperature difference between the coolant in the middle of the flow channel 101 and the coolant on both sides of the flow channel 101, making the temperature of the coolant in the flow channel 101 more uniform, and optimizing the heat dissipation effect of the liquid cooling plate body 1.

[0039] In order to prevent the shunt pipe 44 from diverting too much coolant, the ratio of the diameter of the shunt pipe 44 to the diameter of the liquid inlet 2 is set to 1:4 to 1:5, and the shunt pipe 44 is provided with a straight portion 441 and a bent portion 443, and an inclined portion 442 is provided between the straight portion 441 and the bent portion 443. The setting of the bent portion 443 helps the coolant to enter the guide groove 43.

[0040] Reference Figure 6 As shown, the inner bottom wall of the guide groove 43 is provided with a slope, and the slope is set to 5°-10°. The slope helps the coolant to flow from one end close to the shunt pipe 44 to the end away from the shunt pipe 44, so that the edge of the cooling cotton 42 can absorb the coolant, thereby accelerating the speed at which the coolant penetrates the cooling cotton 42.

[0041] Embodiment 2

[0042] The cooling cotton 42 cools the bottom of the liquid cooling plate body 1 and can take away the heat on the liquid cooling plate body 1. If the heat accumulates on the cooling cotton 42 all the time, it will affect the cooling effect of the cooling cotton 42. Therefore, a base 5 wrapped around the outside of the frame 41 is installed at the bottom of the liquid cooling plate body 1. The base 5 is arranged in a "C" shape. Ventilation grooves are formed on the base 5, and a ventilation mechanism 6 is arranged on the base 5. The ventilation mechanism 6 is used to increase the air circulation in the base 5. The ventilation mechanism 6 includes a main fan blade 61 rotatably installed at the end of the base 5, and auxiliary fan blades 62 symmetrically distributed on both sides of the main fan blade 61. The auxiliary fan blades 62 are also rotatably installed on the base 5. A driving member 63 is further arranged on the base 5 to drive the main fan blade 61 and the auxiliary fan blades 62 to rotate. By driving the main fan blade 61 and the auxiliary fan blades 62 to rotate, the main fan blade 61 and the auxiliary fan blades 62 can make an air flow form in the ventilation grooves. Since the coolant closer to the middle of the liquid cooling plate body 1 absorbs more heat and its temperature is higher, the ventilation grooves are arranged in a structure that is larger in the middle and smaller on both sides, which can promote the air circulation at the middle position of the bottom of the liquid cooling plate body 1, help the air flow take away the heat on the cooling cotton 42, and can also air-dry the coolant that has already absorbed heat in the cooling cotton 42, facilitating the cooling cotton 42 to absorb new coolant.

[0043] In order to make the main fan blade 61 and the auxiliary fan blades 62 rotate synchronously, the driving member 63 includes a servo motor 631 fixedly installed on the base 5. The output end of the servo motor 631 is fixedly connected to the axis of the main fan blade 61. Synchronous wheels 632 are fixedly sleeved on the axes of the main fan blade 61 and the auxiliary fan blades 62. A synchronous belt 633 is commonly installed outside the plurality of synchronous wheels 632. Driving the servo motor 631 drives the auxiliary fan blades 62 to rotate. The rotation of the auxiliary fan blades 62 drives one of the synchronous wheels 632 to rotate. The synchronous wheel 632 drives the other synchronous wheels 632 to rotate synchronously through the synchronous belt 633, so as to drive the two auxiliary fan blades 62 to rotate synchronously with the main fan blade 61, which helps the air circulation in the base 5.

[0044] Embodiment Three

[0045] Since the air-drying force of the main fan blade 61 and the auxiliary fan blades 62 on the old coolant in the cooling cotton 42 is limited, in order to timely discharge the old coolant in the cooling cotton 42, a pressing plate 45 protrudes from the frame 41 and is installed at the bottom of the cooling cotton 42. A plurality of holes are formed in the pressing plate 45, and telescopic rods 46 are symmetrically installed on one side of the top of the pressing plate 45, and a connecting spring 47 is installed on the other side of the top of the pressing plate 45. The telescopic rods 46 and the connecting spring 47 are both fixedly installed at the bottom of the liquid cooling plate body 1. The telescopic rods 46 and the connecting spring 47 can support the pressing plate 45 and hang the pressing plate 45 below the cooling cotton 42. When the pressing plate 45 moves upward, it can squeeze the cooling cotton 42 to squeeze out the old coolant in the cooling cotton 42. The old coolant can drip from the holes, and the cooling cotton 42 can continuously absorb new coolant, continuously ensuring the good cooling effect of the cooling cotton 42.

[0046] In order to realize the function of the above-mentioned pressing plate 45, a transmission member 64 for repeatedly pressing the pressing plate 45 upward is provided on the auxiliary blade 62, wherein a rotating rod 641 is rotatably installed at the end of the base 5, a connecting seat 642 is rotatably connected to one end of the rotating rod 641, and an extrusion platform 643 is rotatably connected to the other end of the rotating rod 641, and the connecting seat 642 and the extrusion platform 643 are both slidably installed on the base 5, and a roller 644 is rotatably installed on the edge of the pressing plate 45, and a 20°-35° roller is provided on the extrusion platform 643. The roller 644 is in contact with the slope 647. A connecting rod 1 645 is rotatably mounted on one side of the connecting seat 642. A connecting rod 2 646 is fixedly mounted on the axis of the auxiliary fan blade 62. The end of the connecting rod 2 646 is rotatably connected to the end of the connecting rod 1 645. When the auxiliary fan blade 62 rotates, the connecting rod 2 646 can be driven to rotate. The connecting rod 2 646 drives the connecting seat 642 to slide back and forth through the connecting rod 1 645. The sliding of the connecting rod 1 645 drives the rotating rod 641 to swing back and forth. The swing of the rotating rod 641 drives The extrusion platform 643 slides back and forth. When the extrusion platform 643 slides toward the pressure plate 45, the pressure plate 45 can be pushed up due to the action of the slope 647. At the same time, the roller 644 can improve the smoothness of the sliding of the extrusion platform 643. At this time, the connecting spring 47 is deformed. When the extrusion platform 643 slides in the opposite direction, the pressure plate 45 can move downward and reset by the elastic force of the connecting spring 47. Since the bottom of the cooling cotton 42 protrudes from the frame 41, the protruding height can provide space for the pressure plate 45 to slide upward. During this time, the pressure plate 45 squeezes the cooling cotton 42. As the auxiliary fan blade 62 rotates, the pressure plate 45 can move back and forth up and down, so that the pressure plate 45 can continuously squeeze the cooling cotton 42 upward, and the old coolant in the cooling cotton 42 can be continuously squeezed out. As the new coolant is continuously input from the liquid inlet 2, the coolant in the cooling cotton 42 can be continuously and automatically replaced, so that the cooling cotton 42 always maintains a good cooling state, which helps to maintain the uniformity of the temperature of the liquid cooling plate body 1.

[0047] Embodiment 4

[0048] The coolant squeezed and dripped by the pressure plate 45 will fall into the base 5. In order to save resources, the coolant can be recycled. Therefore, an arc surface 51 is provided on the inner wall of the base 5, and a strip hole 52 is provided on the arc surface 51. A recycling chamber 53 connected with the strip hole 52 is provided inside the base 5. An arc surface 51 is provided on the inner bottom wall of the base 5, and a strip hole 52 is provided on the arc surface 51. A recycling chamber 53 connected with the strip hole 52 is provided inside the base 5. A discharge pipe 54 connected with the recovery chamber 53 is installed on one side of the base 5, and a sealing cap is installed on the end of the discharge pipe 54. The coolant dripping on the base 5 can flow along the arc surface 51 to the strip hole 52, and then fall into the recovery chamber 53 from the strip hole 52. The coolant is collected by the recovery chamber 53. When a certain amount of coolant is collected in the recovery chamber 53, the sealing cap can be opened to discharge the coolant from the discharge pipe 54, so as to facilitate the unified recycling and reuse of the coolant.

[0049] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
