Description

Technical Field

[0001] The invention relates to the technical field of heat exchange and heat dissipation, and in particular to a heat dissipation module with high heat exchange efficiency. Background Art

[0002] Heat exchange cooling refers to the process of transferring heat from one medium to another through a heat exchanger to achieve effective heat dissipation. This process is widely used in many fields. The most common one is the heat dissipation in electronic equipment, such as the heat dissipation of chips in computers and graphics cards, etc.

[0003] In the prior art, a Chinese patent with publication number CN1536311A discloses a heat dissipation device for a heat exchanger, which is composed of a manifold seat, a manifold and a heat sink. The manifold seat is used to guide the gas; the manifold is installed between the manifold seats according to a certain width and length, and guides the gas from the manifold seat on one side to the manifold seat on the other side; the heat sink is installed between the manifolds for heat dissipation. For the heat exchanger of the above structure, the present invention provides a heat dissipation device for a heat exchanger having the following structure: a front protrusion is formed on the heat sink, and the front protrusion protrudes in the direction of air flow and protrudes a certain length compared to the width of the manifold. In addition, a rear protrusion is formed on the heat sink, and the rear protrusion protrudes in the opposite direction of air flow and protrudes a certain length compared to the width of the manifold.

[0004]

[0014] As another example in the prior art, a Chinese patent with publication number CN221924676U discloses a high-efficiency radiator based on a special-shaped cross-section and high-fit heat pipe, comprising a radiator body, a plurality of heat fins are installed on one side of the radiator body, a heat sink is arranged on one side of the radiator fins, a plurality of heat pipes are inserted inside the radiator fins, one end of the heat pipe is cylindrical, a trapezoidal connector is arranged on the other end of the heat pipe, the trapezoidal connector is connected to the heat sink, a plurality of the trapezoidal connectors are welded to each other, and the arrangement of the trapezoidal connector at one end of the heat pipe enables the heat pipes to be tightly connected, increases the heat conduction efficiency between the plurality of heat pipes, enables them to become the same whole, avoids the uneven heat dissipation efficiency caused by different lengths of the heat pipes, thereby greatly increasing the heat dissipation efficiency of the radiator body and balancing the heat dissipation efficiency of each part of the radiator.

[0005] As another example in the prior art, a Chinese patent with publication number CN211601637U discloses a heat dissipation module structure with staggered heat sinks, which at least includes a first heat sink and a second heat sink that are spaced apart and arranged side by side in an upper and lower manner, and a baseline is defined along the side edge of the air inlet side thereof, wherein the first heat sink is provided with a first buckling portion on the air inlet side that is buckled with the second heat sink, and the first buckling portion divides the air inlet side of the first heat sink into an adjacent first section and a second section; the second heat sink is provided with a second buckling portion on the air inlet side that is buckled with the first heat sink, and the second buckling portion divides the air inlet side of the second heat sink into an adjacent third section and a fourth section, which are adjacent to the positions of the above-mentioned first section and second section, respectively.

[0006] Based on the above materials, it can be seen that in the prior art, heat exchange radiators generally use cooling fins and copper tubes to achieve the purpose of heat dissipation. However, in actual use, the surface area of ​​the copper tube is limited, so its contact area with the airflow is limited, which ultimately leads to the overall heat dissipation effect failing to achieve the ideal effect. Summary of the invention

[0007] The object of the present invention is to provide a heat dissipation module with high heat exchange efficiency to solve the problem of limited heat exchange contact area of ​​copper tubes mentioned in the above background technology.

[0008] To achieve the above object, the present invention provides the following technical solution: a heat dissipation module with high heat exchange efficiency, comprising heat dissipation fins, a front fan is installed on the front side of the heat dissipation fins, and a rear fan is installed on the rear side of the heat dissipation fins, and further comprising:

[0009] The heat dissipation fins are configured as evenly stacked sheet aluminum structures, and a heat exchange copper tube is installed through the heat dissipation fins, and evaporative liquid is stored in the heat exchange copper tube. An expansion mechanism for increasing the heat exchange area is provided at the upper end of the heat exchange copper tube;

[0010] A contact block is fixedly installed on the outside of the lower end of the heat exchange copper tube, a plugging bolt is threadedly installed on the upper end of the heat exchange copper tube, and a sealing ring matching the heat exchange copper tube is installed on the lower surface of the plugging bolt, and a heat spreader with a smooth surface is fixedly installed on the lower surface of the contact block;

[0011] The side of the heat dissipation fin is fixedly mounted with a mounting block for mounting the front fan and the rear fan;

[0012] Symmetrically arranged guide rods are fixedly installed above the heat dissipation fins, and a mounting plate is arranged between the guide rods on both sides, and a vibration mechanism for knocking and cleaning is arranged between the mounting plate and the heat dissipation fins.

[0013] Preferably, the expansion mechanism comprises an expansion tube fixedly mounted on the upper end of the heat exchange copper tube, and adjacent heat exchange copper tubes are interconnected via the expansion tube, and the expansion tube is also made of copper material.

[0014] Preferably, a surface convex ball for increasing the surface of the expansion tube is fixedly mounted on the outer surface of the expansion tube, and through grooves for air flow to pass through are evenly opened on the inner side of the expansion tube.

[0015] Preferably, a first guide plate is fixedly installed between the upper and lower heat dissipation fins, and the angle between the first guide plate and the expansion tube is 45°, and a second guide plate is fixedly installed on the side of the first guide plate.

[0016] Preferably, the second guide plates are evenly arranged at equal intervals, and the angle between the second guide plates and the expansion tube is 90°.

[0017] Preferably, a storage box for storing evaporative liquid is fixedly installed above the contact block, and the storage box is communicated with the heat exchange copper tube via a delivery pipe fixedly installed on the lower surface of the storage box, and a temperature sensor is fixedly installed inside the storage box.

[0018] Preferably, a thread groove with an internal thread structure is provided on the outer surface of the mounting block, and the thread groove is arranged as a strip structure, and a rubber shock-absorbing pad is fixedly installed at the edge of the outer surface of the mounting block.

[0019] Preferably, the vibration mechanism includes a knocking ball installed below the mounting plate, and a compression spring is fixedly installed between the knocking ball and the mounting plate.

[0020] Preferably, sliding sleeves are fixedly installed on the left and right sides of the mounting plate, and a through-type sliding structure is formed between the sliding sleeves and the guide rods.

[0021] Preferably, a push handle for manual operation is fixedly mounted on the upper surface of the mounting plate, and the knocking ball and the extrusion strip are pressed against each other, and the extrusion strips are fixedly mounted on the upper surface of the heat dissipation fins at equal intervals.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the heat dissipation module with high heat exchange efficiency adopts a new structural design, the specific contents of which are as follows:

[0023] 1. The heat spreader on the lower surface of the contact block is in contact with the device that needs to dissipate heat. When the temperature rises, the evaporative liquid inside the heat exchange copper tube evaporates, and the evaporation absorbs heat, thereby achieving the purpose of heat exchange and heat dissipation. At the same time, the fan drives the air flow to cool the evaporated evaporative liquid in the heat exchange copper tube;

[0024] Furthermore, an expansion tube is arranged at the upper end of the heat exchange copper tube, and the expansion tube is used to increase the surface area of ​​the heat exchange copper tube as a whole, thereby increasing the contact area between the whole tube and the airflow during heat dissipation, and improving the overall heat dissipation effect. The surface convex ball is installed on the outer surface of the expansion tube, which can better increase the surface area, and a through groove is provided on the inner side of the expansion tube, which can allow the airflow to pass normally.

[0025] Furthermore, a first guide plate and a second guide plate are fixedly installed between the upper and lower heat dissipation fins. Since the first guide plate is installed at an angle, the airflow generated by the fan hits the first guide plate to change the wind direction, and then cooperates with the second guide plate to guide the airflow to the side of the expansion tube, avoiding obstruction between the heat exchange copper tubes and affecting the heat dissipation effect.

[0026] 2. The evaporating liquid is stored in a storage box. When evaporating, it flows into the heat exchange copper tube through the delivery pipe. At this time, the temperature sensor in the storage box can detect the temperature of the evaporating liquid in real time, which indirectly reflects the temperature of the heat dissipation equipment and determines the heat dissipation effect.

[0027] 3. After the device has been used for a period of time, the staff pushes the handle to move the mounting plate. At this time, the sliding sleeves on both sides of the mounting plate slide accordingly outside the guide rod. During the movement of the mounting plate, the knocking ball at its lower end is intermittently squeezed between the extrusion strips. Cooperating with the elastic reset effect of the extrusion spring, the knocking ball knocks on the heat sink fins to shake off the dust on the surface of the heat sink fins. The shaken dust is carried out with the airflow, achieving the purpose of cleaning and preventing dust adhesion from affecting the heat exchange effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] 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.

[0040] Example 1: Please refer to Figure 1-Figure 6 In order to achieve the purpose of heat exchange and heat dissipation, the present embodiment provides the following technical solutions, which specifically disclose: a heat dissipation fin 1, a front fan 2 is installed on the front side of the heat dissipation fin 1, and a rear fan 3 is installed on the rear side of the heat dissipation fin 1, the heat dissipation fin 1 is arranged as a uniformly stacked sheet aluminum structure, and a heat exchange copper tube 4 is installed through the inside of the heat dissipation fin 1, and the heat exchange copper tube 4 stores evaporative liquid, a contact block 5 is fixedly installed on the outside of the lower end of the heat exchange copper tube 4, a plugging bolt 10 is threadedly installed on the upper end of the heat exchange copper tube 4, and a sealing ring 11 matching the heat exchange copper tube 4 is installed on the lower surface of the plugging bolt 10, and the contact block 5 A heat spreader 7 with a smooth surface is fixedly mounted on the lower surface, a mounting block 12 for mounting the front fan 2 and the rear fan 3 is fixedly mounted on the side of the heat dissipation fin 1, a thread groove 13 with an internal thread structure is opened on the outer surface of the mounting block 12, and the thread groove 13 is arranged in a strip structure, and a rubber shock-absorbing pad 14 is fixedly mounted on the edge of the outer surface of the mounting block 12, a storage box 6 for storing evaporative liquid is fixedly mounted above the contact block 5, and the storage box 6 is connected with the heat exchange copper tube 4 through a delivery pipe 8 fixedly mounted on its lower surface, and a temperature sensor 9 is fixedly mounted inside the storage box 6.

[0041] When using the device, first install the front fan 2 and the rear fan 3 on the front and rear sides of the heat dissipation fin 1 respectively, and the front fan 2 and the rear fan 3 are connected to the mounting block 12 on the outer surface of the heat dissipation fin 1 through bolts, and the bolts are screwed into the threaded groove 13 opened on the surface of the mounting block 12 (because the threaded groove 13 is a strip structure, it can adapt to the installation and fixation of fans of different sizes). After the fixation is completed, the shock-absorbing pad 14 is used to reduce the vibration of the fan to reduce the noise during the use of the fan, and then the contact block 5 at the lower end of the device is fixed to the part that needs heat dissipation (such as the computer CPU and graphics card chip, etc.). After being coated with silicone grease, the heat spreader 7 is in direct contact with the equipment. The heat generated when the equipment is working is transferred to the heat exchange copper tube 4, so that the evaporative liquid in the heat exchange copper tube 4 evaporates and absorbs heat (the evaporative liquid flows from the storage box 6 into the heat exchange copper tube 4 through the delivery pipe 8. During this process, the temperature sensor 9 is used to monitor the temperature of the evaporative liquid in real time to judge the heat dissipation effect). According to actual conditions, the sealing bolt 10 can be opened to replace the evaporation in the heat exchange copper tube 4. At the same time, the front fan 2 and the rear fan 3 are turned on to drive the gas flow, and the airflow is used to cool the evaporated evaporative liquid in the heat exchange copper tube 4, so that it re-forms into water droplets and falls down.

[0042] Example 2: Please refer to Figure 7-Figure 8 In order to achieve the purpose of increasing the heat exchange and heat dissipation effect, the present embodiment provides the following technical solutions to expand the contact area between the heat exchange copper tube 4 and the airflow, and specifically discloses: an expansion mechanism for increasing the heat exchange area is provided at the upper end of the heat exchange copper tube 4, and the expansion mechanism includes an expansion tube 15 fixedly installed at the upper end of the heat exchange copper tube 4, and adjacent heat exchange copper tubes 4 are interconnected through the expansion tube 15, and the expansion tube 15 is also set to a copper material, and a surface convex ball 16 for increasing its surface is fixedly installed on the outer surface of the expansion tube 15, and a through groove 17 for airflow to pass through is evenly opened on the inner side of the expansion tube 15, a first guide plate 18 is fixedly installed between the upper and lower heat dissipation fins 1, and the angle between the first guide plate 18 and the expansion tube 15 is 45°, and a second guide plate 19 is fixedly installed on the side of the first guide plate 18, and the second guide plates 19 are evenly arranged at equal intervals, and the angle between the second guide plate 19 and the expansion tube 15 is 90°

[0043] The fan drives the airflow to pass through the gaps between the heat dissipation fins 1. When the airflow hits the first guide plate 18, its flow direction is changed. At the same time, the second guide plate 19 on the side of the first guide plate 18 guides the gas to the direction perpendicular to the heat exchange copper tube 4 to avoid obstruction between the heat exchange copper tubes 4 and affect the heat dissipation effect. In this process, the expansion tube 15 at the upper end of the heat exchange copper tube 4 is used to increase the contact area with the airflow (the surface of the expansion tube 15 is provided with a surface convex ball 16, and the airflow passes through the through groove 17 opened in the expansion tube 15).

[0044] Example 3: Please refer to Figure 9-10In order to solve the problem that dust accumulation affects the heat exchange effect of traditional devices after long-term use, this embodiment provides the following technical solutions, adding a manual vibration dust removal mechanism, specifically disclosing: symmetrically arranged guide rods 20 are fixedly installed above the heat dissipation fins 1, and a mounting plate 21 is arranged between the guide rods 20 on both sides, and the mounting plate 21 and the heat dissipation fins 1 are provided with a vibration mechanism for knocking and cleaning, the vibration mechanism includes a knocking ball 24 installed below the mounting plate 21, and an extrusion spring 23 is fixedly installed between the knocking ball 24 and the mounting plate 21, sliding sleeves 22 are fixedly installed on the left and right sides of the mounting plate 21, and a through-type sliding structure is formed between the sliding sleeve 22 and the guide rods 20, a pushing handle 26 for manual operation is fixedly installed on the upper surface of the mounting plate 21, and the knocking ball 24 and the extrusion strips 25 are correspondingly squeezed with each other, and the extrusion strips 25 are fixedly installed on the upper surface of the heat dissipation fins 1 at equal intervals.

[0045] After using it for a period of time, the staff pushes the mounting plate 21 by pushing the handle 26. At this time, the sliding sleeve 22 on the side of the mounting plate 21 slides accordingly outside the guide rod 20, so that the mounting plate 21 drives the knocking ball 24 below it to move. During the movement, the knocking ball 24 is intermittently squeezed with the extrusion strip 25 (the extrusion strip 25 is fixedly connected to the heat sink 1). After the extrusion, the elastic pushing action of the extrusion spring 23 pushes the knocking ball 24 and the heat sink fin 1 to knock against each other, and the knocking makes the heat sink fin 1 vibrate. Under the action of the vibration, the dust accumulated on the surface of the heat sink fin 1 is shaken off, and the shaken-off dust is carried out with the airflow, thereby achieving the purpose of cleaning.
