Description

Technical Field

[0001] The present invention relates to the technical field of heat pipe radiators, in particular to a multi-channel parallel heat pipe radiator. Background Art

[0002] A heat pipe radiator is a heat transfer element with extremely high thermal conductivity. It uses heat pipes as the main medium and transfers heat through the evaporation and condensation of liquid in a fully enclosed vacuum tube. Combined with cooling fins and fans, it continuously dissipates heat. It is widely used to dissipate heat from various electrical devices. However, existing heat pipe radiators have the following problems when used:

[0003] Heat pipe radiators are generally installed on electrical components through a base and conduct heat through multiple heat pipes. However, existing heat pipe radiators are not convenient for parallel heat dissipation of multiple heat pipes. If there is a local temperature difference, the heat dissipation effect of each heat pipe will also deviate, which is not conducive to the stable regulation of the overall temperature. Furthermore, the use of parallel heat dissipation and the selection of liquid cooling have a better effect on temperature stability. Due to the different electrical components targeted, the installation position of the heat pipe radiator is also different. For horizontal and vertical installations, attention should be paid to internal leakage and sealing issues to avoid leakage causing circuit short circuits and other situations.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original heat pipe radiator. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-channel parallel heat pipe radiator to solve the above-mentioned background technology. The existing heat pipe radiator is not convenient for parallel heat dissipation of multiple heat pipes, and at the same time, attention needs to be paid to internal leakage and sealing. The technical solution of the present invention addresses the technical problem that the existing technical solution is too single and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-channel parallel heat pipe radiator, comprising a base, a connecting cavity defined in the base, heat pipes being installed on both sides of the connecting cavity, the tops of the heat pipes being installed on heat dissipation fins, and the heat dissipation fins being located above the base, and the connecting cavity being filled with coolant;

[0007] It also includes a pressure-bearing piece, which is installed on both sides of the communication cavity through an elastic telescopic rod, and the pressure-bearing piece is fitted on the heat pipe, the heat pipe is sleeved with a first sealing ring, and the first sealing ring is embedded in the base, a compression ring is provided on the outer side of the first sealing ring, and a compression sleeve is slidably installed on the inner side of the compression ring, a first driving assembly is provided between the pressure-bearing piece and the compression ring, and the first driving assembly is used to drive the compression ring to rotate;

[0008] The second sealing ring is sleeved on the heat pipe, and the second sealing ring is embedded in the base, and the second sealing ring is located on the outside of the heat pipe. A second driving assembly is provided between the second sealing ring and the clamping ring, and the second driving assembly is used to drive the clamping ring to rotate again.

[0009] Preferably, the inner wall of the compression sleeve is designed as a slope structure, and the inner wall of the compression sleeve is in contact with the first sealing ring. The protruding part of the compression sleeve slides within the recessed area of the compression ring, and the compression sleeve is threadedly installed in the base.

[0010] Preferably, the first drive assembly includes a push rod, which is fixed on the outer side wall of the pressure plate, and an oil tank is fixed to the outer end of the push rod. The oil tank is embedded and movably installed in the base, and a first piston rod is arranged in the oil tank. The outer end of the first piston rod is located in the guide groove, and the guide groove is opened on the outside of the clamping ring.

[0011] Preferably, the push rods are distributed at equal angles with respect to the central axis of the inner end of the heat pipe, and the push rods are parallel to the elastic telescopic rods.

[0012] Preferably, the first piston rod is designed to be an "L"-shaped structure, and the first piston rod slides in the guide groove, and the guide groove is distributed obliquely in an arc shape on the clamping ring.

[0013] Preferably, the second sealing ring is made of water-swelling rubber material, and the second sealing ring expands outward after absorbing water.

[0014] Preferably, the second drive assembly includes a pressure plate, which is arranged on the outside of the second sealing ring and is connected to the inner wall of the cavity at the corresponding position inside the base through a spring. A second piston rod is fixed to the outside of the pressure plate, and the second piston rod is located in the oil cavity. The oil cavity is opened inside the base, and the oil cavity is connected to the oil tank through a hose.

[0015] Preferably, the pressure plates are distributed at equal angles outside the second sealing ring, and when the second piston rod on the pressure plate moves outward, it drives the first piston rod to move toward the clamping ring.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By filling the communication cavity with coolant, the temperature can be absorbed and evenly distributed first, and then the heat pipe and heat dissipation fins are used to dissipate heat. This method can ensure overall stability and balance, and effectively avoid the impact of local excessive temperature on the heat pipe. At the same time, when the temperature is low, the coolant can also be used to protect the heat pipe first, to prevent the working fluid in the pipe from freezing at the condensation end of the heat pipe during startup and causing the evaporation section to dry up. On this basis, when the base is placed horizontally, if leakage occurs, the second sealing ring expands and drives the clamping ring to rotate through the second driving mechanism, thereby driving the clamping sleeve to rotate and move. The inclined structure of the clamping sleeve squeezes the first sealing ring in a relatively smooth manner, thereby improving its sealing effect.

[0018] 2. When the base is placed vertically, the pressure-bearing plate in the corresponding area is moved by the liquid pressure, and the compression ring is driven to rotate through the push rod, the oil tank and the first piston rod. Similarly, the compression sleeve is driven to rotate and move, and the first sealing ring is compressed in advance. During this process, if leakage occurs, the expansion of the second sealing ring will not only compress the first sealing ring, but also further compress itself, further improving the sealing performance and thus increasing the service life. The whole process does not require manual intervention, is highly spontaneous, and has good practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example 1

[0028] See also Figure 1-Figure 3 and Figure 5 A connecting cavity 2 is provided in the base 1, and heat pipes 3 are installed on both sides of the connecting cavity 2. The top of the heat pipe 3 is installed on the heat dissipation fins 4, and the heat dissipation fins 4 are located above the base 1. The connecting cavity 2 is filled with coolant; a pressure-bearing piece 6 is installed on both sides of the connecting cavity 2 through an elastic telescopic rod 5, and the pressure-bearing piece 6 is fitted on the heat pipe 3. A first sealing ring 7 is provided on the heat pipe 3, and the first sealing ring 7 is embedded in the base 1. A compression ring 8 is provided on the outside of the first sealing ring 7, and a compression sleeve 81 is installed on the inner side of the compression ring 8 for limited sliding. A first driving assembly is provided between the pressure-bearing piece 6 and the compression ring 8, and the first driving assembly is used to drive the compression ring 8 to rotate;

[0029] The inner wall of the compression sleeve 81 is designed as a slope structure, and the inner wall of the compression sleeve 81 is in contact with the first sealing ring 7. The protruding part of the compression sleeve 81 slides within the recessed area of the compression ring 8, and the compression sleeve 81 is threadedly installed on the base 1; the first driving assembly includes a push rod 91, the push rod 91 is fixed on the outer wall of the pressure-bearing plate 6, and the outer end of the push rod 91 is fixed with an oil tank 92, the oil tank 92 is embedded and movably installed in the base 1, and a first piston rod 93 is provided in the oil tank 92, the outer end of the first piston rod 93 is located in the guide groove 94, and the guide groove 94 is opened on the outer side of the compression ring 8; the push rod 91 is distributed at equal angles with respect to the central axis of the inner end of the heat pipe 3, and the push rod 91 is parallel to the elastic telescopic rod 5; the first piston rod 93 is designed as an "L"-shaped structure, and the first piston rod 93 slides in contact with the guide groove 94, and the guide groove 94 is distributed obliquely in an arc shape on the compression ring 8;

[0030] When the base 1 is installed vertically, the corresponding pressure-bearing piece 6 is moved by the pressure of the internal liquid, and the compression ring 8 is driven to rotate through the first driving assembly. The compression ring 8 rotates and drives the compression sleeve 81 to rotate. The compression sleeve 81 rotates on the threaded installation of the base 1, so that it moves when it rotates, and the first sealing ring 7 is compressed in a relatively smooth manner to improve the sealing effect.

[0031] Example 2

[0032] Based on Example 1, please refer to Figure 1-Figure 4 The second sealing ring 10 is sleeved on the heat pipe 3 and embedded in the base 1. The second sealing ring 10 is located outside the heat pipe 3. A second driving assembly is provided between the second sealing ring 10 and the clamping ring 8, and the second driving assembly is used to drive the clamping ring 8 to rotate again. The second sealing ring 10 is made of water-swelling rubber material, and the second sealing ring 10 expands outward after absorbing water.

[0033] The second drive assembly includes a pressure plate 111, which is arranged on the outside of the second sealing ring 10 and is connected to the inner wall of the cavity at a corresponding position inside the base 1 via a spring. A second piston rod 112 is fixed to the outside of the pressure plate 111, and the second piston rod 112 is located in an oil chamber 113. The oil chamber 113 is opened inside the base 1 and is connected to the oil tank 92 via a hose. The pressure plates 111 are distributed at equal angles outside the second sealing ring 10, and when the second piston rod 112 on the pressure plate 111 moves outward, it drives the first piston rod 93 to move toward the clamping ring 8.

[0034] When leakage occurs, the liquid penetrates into the second sealing ring 10, causing the second sealing ring 10 to expand spontaneously, pushing the pressure plate 111 and the second piston rod 112, and driving the first piston rod 93 to move, and then pushing the clamping ring 8 to rotate again, thereby driving the clamping sleeve 81 to rotate and move. Leakage protection is performed by the expansion of the second sealing ring 10 and the re-tightening of the first sealing ring 7.

[0035] Working principle: When using the multi-channel parallel heat pipe radiator, first install the heat pipe radiator on the corresponding equipment. When the base 1 is placed horizontally, the coolant in the communication cavity 2 absorbs heat and makes the temperature evenly distributed. The heat pipe 3 and the heat dissipation fins 4 cooperate with the fan to circulate and dissipate heat. When the first sealing ring 7 leaks, the liquid enters the second sealing ring 10, causing the second sealing ring 10 to expand. On the one hand, the second sealing ring 10 is more closely attached to the heat pipe 3. On the other hand, the expansion space reserved outside the second sealing ring 10 makes the pressure plate The force 111 drives the second piston rod 112 to move in the oil chamber 113, squeezing the oil into the oil tank 92, pushing the first piston rod 93 to move. The first piston rod 93 slides in the guide groove 94, which can drive the clamping ring 8 to rotate. The clamping ring 8 drives the clamping sleeve 81 to rotate through the concave-convex matching structure. The clamping sleeve 81 is connected to the internal thread of the base 1, so that the clamping sleeve 81 can move during the rotation process, and through its internal inclined surface structure, it squeezes the first sealing ring 7 in a relatively smooth manner, thereby improving the sealing performance of the first sealing ring 7;

[0036] When the base 1 is placed horizontally or vertically, the pressure-bearing plate 6 in the corresponding direction moves due to the pressure of the internal coolant. The pressure-bearing plate 6 drives the first piston rod 93 to move through the push rod 91 and the oil tank 92, and cooperates with the guide groove 94 to drive the clamping ring 8 to rotate, and then drives the clamping sleeve 81 to rotate and move, squeezing the first sealing ring 7 to increase its sealing performance. Similarly, when leakage occurs, the second sealing ring 10 will still seal again and squeeze the first sealing ring 7 to further improve the sealing effect.
