Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange equipment, and particularly to an alternating stacked microchannel water-cooled radiator. Background Art

[0002] Heat exchangers, especially liquid-liquid radiators, as key components for heat energy transfer and management, are widely used in many important fields such as internal combustion engine cooling, power electronics heat dissipation, industrial equipment temperature control, and data center cooling. Their core efficiency directly affects the operating stability, energy efficiency level, and service life of the equipment.

[0003] However, with the continuous increase in the power density of modern equipment, the increasingly compact space layout, and the ever-increasing requirements for energy efficiency and reliability, traditional heat exchanger designs face severe challenges in terms of efficiency, performance, heat management, and maintainability. The main technical problems to be solved are as follows: 1. The heat exchange efficiency is limited, and the temperature difference driving force is insufficient. Specifically, traditional radiators mostly adopt co-current or cross-flow designs, where the cooling medium and the heat dissipation medium flow in the same or cross directions. This flow pattern causes the temperature difference (heat conduction driving force) between the two in the flow path to gradually decrease, and even tend to balance at the outlet end (temperature equilibrium problem), significantly reducing the average temperature difference in the entire heat exchange process and becoming a bottleneck restricting the improvement of heat conduction efficiency. At the same time, the fluid flow channels are usually relatively straight, with limited residence time, and the heat exchange interface cannot be fully utilized.

[0004] 2. The contact area and boundary layer effect are obvious, and the heat dissipation method is single. Specifically, the conventional round tube or channel design results in a relatively limited contact area between the fluid and the heat transfer wall (low surface area to volume ratio), and the heat dissipation capacity per unit volume (heat dissipation density) is difficult to meet the requirements of high-power compact equipment. In addition, when the fluid is in a laminar state, a relatively thick "thermal boundary layer" will be formed. The heat conductivity of this layer of fluid is poor, seriously hindering the effective transfer of heat from the fluid core to the pipe wall. Traditional designs often focus on heat exchange between a single medium (such as liquid-liquid), lacking means for efficient secondary heat dissipation with the ambient air, restricting the heat dissipation capacity in scenarios with higher heat loads or limited space.

[0005] 3. Uneven heat distribution and potential risk of heat reflux. Specifically, in a complex heat exchange process, if the heat distribution strategy is improper (such as the unreasonable positions of the high-temperature and low-temperature regions), it may lead to the phenomenon of "heat reflux" in local areas, that is, heat is reversely transferred from the low-temperature fluid that should absorb heat to the high-temperature fluid, resulting in a loss of net heat dissipation efficiency. At the same time, natural forces such as gravity are not fully utilized to assist in optimizing the heat flow direction, and the thermal management stability is insufficient.

[0006] 4. Difficult to maintain, the radiator is prone to clogging and inconvenient to clean. Specifically, in application environments with a large amount of pollutants such as dust and fibers (such as construction machinery and field equipment), the radiator fins (such as finned tubes) are extremely easy to be blocked, seriously affecting the heat dissipation efficiency. The cleaning of traditional radiators usually requires overall disassembly or the use of complex tools, resulting in long equipment downtime and high maintenance costs.

[0007] In summary, it is obvious that there are inconveniences and defects in the prior art during actual use, so it is necessary to improve it. Summary of the Invention

[0008] Aiming at the defects in the prior art, the present invention provides an alternately stacked microchannel water-cooled radiator to solve the problems faced by the radiators in the traditional technology, such as low heat transfer efficiency, insufficient heat dissipation capacity, uneven heat distribution, and difficult maintenance.

A left support block is clamped between the same laminar flow down pipes, and the left support block is arranged close to the outer side wall of the coolant tank.

[0018] As an optimized solution, the corrugated heat dissipation belt arranged in the opening of the laminar flow down pipe is arranged close to its upper and lower pipe walls. Two symmetric mounting buckles are respectively fixed on the left support block and the vertical outer wall of the laminar flow down pipe, and the corrugated heat dissipation belt is hung between the two mounting buckles.

[0019] As an optimized solution, turbulence grooves are respectively machined on the upper and lower pipe walls of the laminar flow down pipe close to the corrugated heat dissipation belt.

[0020] As an optimized solution, the water separation partition is welded on the circumferential inner wall of the circulation water tank, and the water separation partitions are arranged in one-to-one correspondence with the laminar flow up pipes, and the water separation partition is arranged between the upper and lower ports of the laminar flow up pipe, on the side close to the upper port.

[0021] As an optimized solution, the water separation partition divides the interior of the circulation water tank into several intermediate water storage areas. The lowermost intermediate water storage area is externally connected to a water inlet pipe, and the uppermost intermediate water storage area is externally connected to a water return pipe.

[0022] As an optimized solution, a fixed square frame is welded in the middle of the outer end face of the circulation water tank, and a circulation water pump is fixedly installed in the fixed square frame. The water inlet pipe and the water return pipe are respectively fixedly communicated with the circulation water pump.

[0023] As an optimized solution, a right limiting block is press-fitted between two adjacent laminar flow up pipes, and the right limiting block is arranged close to the outer side wall of the circulation water tank. A right support block is clamped between the same laminar flow up pipes, and the right support block is arranged close to the outer side wall of the coolant tank.

[0024] As an optimized solution, the corrugated heat dissipation belt disposed within the opening of the laminar flow upper water pipe is closely attached to its upper and lower pipe walls, and the mounting buckles are also fixedly connected to the vertical outer wall of the right support block and the laminar flow upper water pipe, and the corrugated heat dissipation belt is hung between the two mounting buckles.

[0025] As an optimized solution, two sets of detachable dust-proof modules are respectively provided on the front and rear sides of the mounting frame. Each set of detachable dust-proof modules includes two symmetrical U-shaped card seats, and the two U-shaped card seats are welded to the side end surface of the mounting frame near the lower part. Two symmetrical L-shaped restraint blocks are welded to the side end surface of the mounting frame near the upper part, and the L-shaped restraint blocks and the U-shaped card seats are arranged vertically opposite to each other.

[0026] As an optimized solution, a vertical wire frame is respectively inserted and installed in each U-shaped card seat. The upper end of the vertical wire frame is clamped within the L-shaped restraint block, and a plurality of strip-shaped dust-proof nets are fixed between the two vertical wire frames, and the strip-shaped dust-proof nets are disposed outside the corrugated heat dissipation belt.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention realizes the high efficiency of heat exchange. Specifically, the laminar flow lower liquid pipe (coolant channel) and the laminar flow upper water pipe (circulating water channel) provided in the present invention are alternately stacked and closely contacted to form a physical heat conduction interface. During operation, the forward liquid inlet of the coolant is opposite to the forward water inlet direction of the circulating water (similarly for the reverse direction), ensuring that it is always in a countercurrent state throughout the flow process. The countercurrent design maintains the maximum average temperature difference between the coolant (high temperature) and the circulating water (low temperature), significantly improving the heat conduction efficiency. Heat is directionally conducted through the solid pipe wall (laminar flow lower liquid pipe / upper water pipe), avoiding the temperature equilibrium problem in the co-current heat exchange, and the heat exchange efficiency is increased by more than 30-50%; the liquid distribution partition plate and the water distribution partition plate in the present invention divide the coolant tank and the circulating water tank into multiple intermediate liquid storage areas and intermediate water storage areas, forcing the fluid to form an S-shaped flow path in multiple pipes. The S-shaped flow extends the residence time of the fluid in the radiator and increases the heat exchange duration. The coolant and the circulating water are repeatedly divided and converged in multiple "intermediate area - pipe" units to achieve multiple local heat exchanges, and the overall heat dissipation capacity is improved The present invention enhances the heat dissipation performance of the radiator. Specifically, in the present invention, the laminar flow downpipe and the laminar flow upwater pipe are welded into a U-shaped structure using flat-mouth square pipes. Combined with an alternating stacked layout, a microchannel is formed. The microchannel can increase the contact area between the fluid and the pipe wall (high surface area to volume ratio), strengthening heat conduction. The flat-mouth design reduces the thickness of the fluid boundary layer, facilitating rapid heat transfer. The heat dissipation density per unit volume is high, making it suitable for applications in compact spaces. The wall of the laminar flow downpipe is stamped with turbulator grooves, which can disrupt the laminar flow state. The turbulator grooves generate turbulence when the coolant flows at high speed, enhancing fluid mixing and heat disturbance, and avoiding the problem of "thickening of the thermal boundary layer" caused by laminar flow. The present invention also provides a method of using corrugated heat dissipation fins to assist air cooling. The corrugated heat dissipation fins are fixed inside the pipe opening, directly contacting the pipe wall, and are hung by mounting buckles, increasing the external heat dissipation area. The corrugated structure is used to expand the heat dissipation surface area, and the heat is secondarily dissipated into the environment through natural convection or forced convection of air (such as a fan), forming a "liquid-solid-gas" multi-stage heat dissipation.

[0028] The present invention avoids heat reflux through heat distribution optimization. Specifically, the overall heat distribution of the radiator is "high at the top and low at the bottom" (the high-temperature coolant inlet is at the top, and the low-temperature outlet is at the bottom; the low-temperature circulating water inlet is at the bottom, and the high-temperature outlet is at the top), and the coolant temperature in the same area is always higher than that of the circulating water; the heat conduction is unidirectional (coolant → pipe wall → circulating water), avoiding reverse heat exchange and ensuring stable heat dissipation efficiency.

[0029] The present invention has the advantages of convenient maintenance and environmental adaptability. Specifically, the detachable dust-proof module in the present invention realizes the quick plugging and unplugging of the strip-shaped dust-proof net through a U-shaped card seat, an L-shaped restraint block, and a vertical wire frame. The strip-shaped dust-proof net covers the outside of the corrugated heat dissipation fins, which can block dust accumulation and prevent the corrugated heat dissipation fins from being blocked. The detachable design simplifies cleaning and maintenance, reduces downtime, and is suitable for dusty environments; by increasing or decreasing the number of laminar flow downpipes and laminar flow upwater pipes, the heat dissipation capacity can be adjusted to match different heat load requirements.

The liquid separation partitions 6 are arranged in one-to-one correspondence with the laminar flow downpipes 4, and the liquid separation partitions 6 are arranged between the upper and lower ports of the laminar flow downpipes 4 and on the side close to the upper port.

[0038] A number of liquid separation partitions 6 divide the interior of the coolant tank 2 into multiple transfer liquid storage areas 7.

The corrugated heat dissipation belts 12 are hung between the two mounting buckles 13.

[0042] Turbulence grooves 14 are respectively machined on the upper and lower pipe walls of the lower laminar flow liquid pipe 4 close to the corrugated heat dissipation belts 12. The machining method of the turbulence grooves 14 is stamping.

[0043] The structure, shape and size of the upper laminar flow water pipe 5 are exactly the same as those of the lower laminar flow liquid pipe 4. The opening direction of the upper laminar flow water pipe 5 is opposite to that of the lower laminar flow liquid pipe 4. The upper and lower two ports of each upper laminar flow water pipe 5 are respectively communicated with the circulation water tank 3.

[0044] A plurality of horizontal water distribution partitions 15 are arranged in the circulation water tank 3 from top to bottom. The water distribution partitions 15 are welded to the circumferential inner wall of the circulation water tank 3. The water distribution partitions 15 are arranged in one-to-one correspondence with the upper laminar flow water pipes 5. The water distribution partitions 15 are arranged between the upper and lower ports of the upper laminar flow water pipes 5 and on the side close to the upper port.

[0045] The water distribution partitions 15 divide the interior of the circulation water tank 3 into a plurality of transfer storage water areas 16. The lowermost transfer storage water area 16 is externally connected to the water inlet pipe 17. The uppermost transfer storage water area 16 is externally connected to the water return pipe 18.

[0046] A fixed square frame 19 is welded to the middle of the outer end face of the circulation water tank 3. A circulation water pump 20 is fixedly installed in the fixed square frame 19. The water inlet pipe 17 and the water return pipe 18 are respectively fixedly communicated with the circulation water pump 20.

[0047] The circulation water tank 3, the upper laminar flow water pipe 5, the water inlet pipe 17, the water return pipe 18 and the circulation water pump 20 form the circulating water circuit of the radiator.

[0048] A right limiting block 21 is press-fitted between two adjacent upper laminar flow water pipes 5. The right limiting block 21 is arranged close to the outer side wall of the circulation water tank 3. A right supporting block 22 is clamped between the same upper laminar flow water pipe 5. The right supporting block 22 is arranged close to the outer side wall of the coolant tank 2.

[0049] In the middle opening of each laminar flow upper water pipe 5, a corrugated heat dissipation belt 12 is also fixedly arranged. The corrugated heat dissipation belt 12 is arranged close to the upper and lower pipe walls of the laminar flow upper water pipe 5. Mounting buckles 13 are also fixedly connected to the right support block 22 and the vertical outer wall of the laminar flow upper water pipe 5. The corrugated heat dissipation belt 12 is hung between the two mounting buckles 13.

[0050] On the front and back sides of the mounting plate frame 1, two groups of detachable dust-proof modules are respectively arranged. Each group of detachable dust-proof modules includes two symmetric U-shaped card seats 23. The two U-shaped card seats 23 are welded on the side end surface of the mounting plate frame 1 close to the lower part. Two symmetric L-shaped restraint blocks 24 are welded on the side end surface of the mounting plate frame 1 close to the upper part. The L-shaped restraint blocks 24 are arranged vertically opposite to the U-shaped card seats 23.

[0051] Vertically arranged wire frames 25 are respectively inserted and installed in each U-shaped card seat 23. The upper ends of the vertically arranged wire frames 25 are clamped in the L-shaped restraint blocks 24. A number of strip-shaped dust-proof nets 26 are fixed between the two vertically arranged wire frames 25. The strip-shaped dust-proof nets 26 cover the outside of the corrugated heat dissipation belt 12 and are spaced 5-10 mm from the corrugated heat dissipation belt 12 to prevent dust accumulation and at the same time not affect air convection. The size of the strip-shaped dust-proof nets 26 is larger than the opening sizes of the laminar flow lower liquid pipe 4 and the laminar flow upper water pipe 5.

[0052] When the present invention is in use: First, the liquid inlet pipe 8 and the liquid outlet pipe 9 are respectively connected to the engine coolant pipeline. The high-temperature engine coolant enters the coolant tank 2 through the liquid inlet pipe 8, and then enters the first laminar flow downpipe 4 from the uppermost transfer storage area 7. The coolant first undergoes forward liquid inlet in the laminar flow downpipe 4, and after one reverse turn, it changes to reverse liquid return, so that the engine coolant flows into the next lower transfer storage area 7, and then into the next laminar flow downpipe 4 for the above-mentioned laminar microchannel shunt. After multiple shunts, the coolant forms an S-shaped reciprocating laminar flow in multiple transfer storage areas 7 and multiple laminar flow downpipes 4; Start the circulation water pump 20, and the circulation water pump 20 provides the driving force for the directional flow of the circulating water: The low-temperature circulating water first enters the circulation water tank 3 through the water inlet pipe 17, and then enters the first laminar flow uppipe 5 from the lowermost transfer water storage area 16. The circulating water first undergoes forward water inlet in the laminar flow uppipe 5, and also changes to reverse water return after one reverse turn, and enters the next lower transfer water tank, and then flows into the previous laminar flow uppipe 5 for the above-mentioned laminar microchannel shunt, so as to form an S-shaped reciprocating circulating water laminar flow in multiple transfer water storage areas 16 and multiple laminar flow uppipes 5; Since the adjacent two laminar flow downpipes 4 and laminar flow uppipes 5 are in overlapping contact, and when the high-temperature coolant in the laminar flow downpipe 4 undergoes forward liquid inlet, the low-temperature circulating water in the adjacent laminar flow uppipe 5 is also undergoing forward water inlet, and the directions of the forward liquid inlet and the forward water inlet are opposite. Therefore, during the forward liquid inlet and the forward water inlet, countercurrent heat exchange will occur between the laminar flow downpipe 4 and the laminar flow uppipe 5, and the heat is conducted from the high-temperature coolant to the low-temperature circulating water through the solid to achieve heat exchange and the purpose of heat dissipation; The turbulence grooves 14 provided on the inner wall of the laminar flow downpipe 4 can cause turbulence to the coolant, forming a turbulent flow, and preventing the problems of insufficient heat exchange time and poor heat exchange effect caused by too fast coolant flow rate; Further, during the reverse liquid return and the reverse water return, the flow direction of the coolant in the laminar flow downpipe 4 is also opposite to the flow direction of the circulating water in the laminar flow uppipe 5, which makes the coolant and the circulating water undergo heat exchange through the contact of the laminar flow downpipe 4 and the laminar flow uppipe 5 whether during the liquid inlet and water inlet or the liquid return and water return, so as to increase the heat exchange area and achieve efficient heat dissipation; In addition, in the entire radiator, the overall distribution of heat is high at the top and low at the bottom, and the temperature of the circulating water in the laminar flow uppipe 5 in the same area is always lower than the temperature of the coolant in the laminar flow downpipe 4, which makes the heat can only be directionally conducted from the coolant to the circulating water and no reverse heat exchange will occur; The multiple corrugated heat dissipation belts 12 provided in the radiator can dissipate the heat to the air through direct contact with the laminar flow downpipe 4 and the laminar flow uppipe 5, and then take away the heat through air flow; The radiator is also provided with a slidable and detachable dust prevention module. The dust prevention module includes several strip-shaped dust prevention nets 26. The strip-shaped dust prevention nets 26 are arranged outside the corrugated heat dissipation belts 12, which can prevent the problem of the reduction of the heat exchange efficiency of the corrugated heat dissipation belts 12 caused by dust accumulation, and the detachable design is also convenient for subsequent cleaning and maintenance.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
