Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat exchange equipment, in particular to an alternating stacked micro-channel water cooling radiator. BACKGROUND

[0002] As a key component of heat energy transfer and management, heat exchangers, especially liquid-liquid radiators, are widely used in internal combustion engine cooling, power electronics heat dissipation, industrial equipment temperature control, data center cooling and other important fields. Its core performance directly affects the running stability, energy efficiency and service life of the equipment.

[0003] However, with the continuous increase of power density of modern equipment, the increasingly compact space layout, and the increasing requirements for energy efficiency and reliability, the traditional heat exchanger design faces severe challenges in efficiency, performance, heat management and maintainability, and mainly has the following technical problems to be solved:

[0004] 1. The heat exchange efficiency is limited, and the temperature difference driving force is insufficient. Specifically, the traditional radiator adopts a parallel flow or cross flow design, and the cooling medium and the heat dissipation medium have the same flow direction or cross flow. This flow mode causes the temperature difference (heat conduction driving force) between the two in the flow path to gradually decrease, and even tends to be balanced at the outlet end (temperature balance problem), significantly reducing the average temperature difference in the entire heat exchange process, which becomes a bottleneck restricting the improvement of heat conduction efficiency. At the same time, the fluid flow channel is usually relatively straight, and the residence time is limited, which cannot fully utilize the heat exchange interface.

[0005] 2. The contact area and boundary layer effect are obvious, and the heat dissipation mode is single. Specifically, the conventional circular tube or channel design causes the contact area of the fluid and the heat transfer wall to be relatively limited (low surface area to volume ratio), and the heat dissipation density per unit volume is difficult to meet the needs of high-power compact equipment. In addition, the fluid will form a relatively thick "thermal boundary layer" in the laminar state, which has poor heat conductivity, seriously hindering the effective transfer of heat from the fluid core to the pipe wall; traditional design often focuses on the heat exchange between single medium (such as liquid-liquid), and lacks means for efficient secondary heat dissipation with ambient air, limiting the heat dissipation capacity in higher heat load or space limited scenarios.

[0006] 3. Uneven heat distribution and potential heat backflow risk. Specifically, in the complex heat exchange process, if the heat distribution strategy is improper (such as unreasonable position of high temperature zone and low temperature zone), it may cause "heat backflow" phenomenon in local area, that is, heat is transferred from low temperature fluid which should absorb heat to high temperature fluid, causing net heat dissipation efficiency loss. At the same time, the natural forces such as gravity are not fully utilized to assist in optimizing the heat flow direction, and the heat management stability is insufficient.

[0007] 4. Difficult maintenance: Radiators are prone to clogging and difficult to clean. Specifically, in environments with high levels of dust, fiber, and other contaminants (such as construction machinery and field equipment), heat sinks (e.g., fins) are prone to clogging, severely impacting heat dissipation efficiency. Cleaning traditional radiators often requires complete disassembly or the use of complex tools, resulting in prolonged equipment downtime and high maintenance costs.

[0008] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0009] In response to the defects in the existing technology, the present invention provides an alternating stacked microchannel water-cooled radiator to solve the problems faced by radiators in traditional technology, such as low heat exchange efficiency, insufficient heat dissipation capacity, uneven heat distribution, and difficult maintenance.

[0010] To achieve the above object, the present invention provides the following technical solutions:

[0011] An alternating stacked microchannel water-cooled radiator comprises a square mounting plate frame, on both sides of which inner walls are respectively welded and fixed a coolant tank and a circulating water tank of the same shape and size.

[0012] As an optimized solution, a plurality of laminar flow lower liquid pipes and laminar flow upper water pipes are provided between the coolant tank and the circulating water tank, and the plurality of laminar flow lower liquid pipes and the plurality of laminar flow upper water pipes are alternately stacked.

[0013] As an optimized solution, the laminar flow liquid pipe is a U-shaped pipe with a transverse opening, and the laminar flow liquid pipe is welded by three sections of flat square pipes. The upper and lower ports of each laminar flow liquid pipe are respectively connected to the coolant tank.

[0014] As an optimized solution, the structure, shape and size of the laminar flow upper water pipe are exactly the same as those of the laminar flow lower liquid pipe. The opening direction of the laminar flow upper water pipe is opposite to the opening direction of the laminar flow lower liquid pipe. The upper and lower ports of each laminar flow upper water pipe are respectively connected to the circulating water tank.

[0015] As an optimized solution, a corrugated heat dissipation belt is fixedly provided in the transverse opening of each of the laminar flow lower liquid pipes, and a corrugated heat dissipation belt is also fixedly provided in the transverse opening of each of the laminar flow upper water pipes.

The liquid separation partition is arranged between the upper and lower ports of the laminar downflow pipe, on the side close to the upper port.

[0018] As an optimized solution, several liquid separation partitions divide the interior of the coolant tank into multiple transfer liquid storage areas. A liquid inlet pipe is welded on the outer end surface of the coolant tank near the upper part, and the liquid inlet pipe is connected to the uppermost transfer liquid storage area.

[0019] As an optimized solution, a left limit block is pressed between two adjacent laminar flow liquid pipes, and the left limit block is set close to the outer wall of the coolant tank. A left support block is clamped between the same laminar flow liquid pipe, and the left support block is set close to the outer wall of the coolant tank.

[0020] As an optimized solution, the corrugated heat dissipation belt arranged in the opening of the laminar downpipe is arranged close to the upper and lower pipe walls, and two symmetrical mounting clips are respectively fixed on the left support block and the vertical outer wall of the laminar downpipe, and the corrugated heat dissipation belt is hung between the two mounting clips.

[0021] As an optimized solution, the upper and lower tube walls of the laminar flow lower liquid pipe, which are close to the corrugated heat dissipation belt, are respectively processed with spoiler grooves.

[0022] As an optimized solution, the water-dividing baffle is welded on the circumferential inner wall of the circulating water tank, and the water-dividing baffle is arranged in a one-to-one correspondence with the laminar upper water pipe. The water-dividing baffle is arranged between the upper and lower ports of the laminar upper water pipe, close to the upper port.

[0023] As an optimized solution, the water dividing partition divides the interior of the circulating water tank into several intermediate water storage areas. The intermediate water storage area at the bottom is connected to an inlet pipe, and the intermediate water storage area at the top is connected to a return pipe.

[0024] As an optimized solution, a fixed frame is welded to the middle of the outer end surface of the circulating water tank, a circulating water pump is fixedly installed in the fixed frame, and the water inlet pipe and the return pipe are respectively fixedly connected to the circulating water pump.

[0025] As an optimized solution, a right-side limit block is pressed between two adjacent laminar water pipes, and the right-side limit block is set close to the outer wall of the circulating water tank. A right-side support block is clamped between the same laminar water pipe, and the right-side support block is set close to the outer wall of the circulating water tank.

[0027] As an optimized solution, two groups of detachable dustproof modules are respectively provided on the front and rear sides of the mounting plate frame, and each group of the detachable dustproof modules includes two symmetrical U-shaped holders, and the two U-shaped holders are welded on the side end surface of the mounting plate frame near the lower part, and two symmetrical L-shaped restraint blocks are welded on the side end surface of the mounting plate frame near the upper part, and the L-shaped restraint blocks are arranged opposite to the U-shaped holders up and down.

[0028] As an optimized solution, a vertical grid is installed in each U-shaped socket, the upper end of the vertical grid is clamped in the L-shaped constraint block, and several strip dustproof nets are fixed between the two vertical grids. The strip dustproof nets are arranged on the outside of the corrugated heat dissipation belt.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The present invention achieves high efficiency in heat exchange. Specifically, the laminar flow lower liquid pipe (cooling liquid channel) and laminar flow upper water pipe (circulating water channel) provided in the present invention are alternately stacked and in close contact, forming a physical heat conduction interface. During operation, the forward inlet direction of the coolant is opposite to the forward inlet direction of the circulating water (the same applies in the reverse direction), ensuring that the flow is always in a countercurrent state throughout the entire 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 directed through the solid pipe wall (laminar flow lower liquid pipe / upper water pipe), avoiding the temperature balance problem in the downstream heat exchange, and the heat exchange efficiency is improved by more than 30-50%; the liquid separation partition and water separation partition in the present invention separate the coolant tank and the circulating water tank into multiple transfer liquid storage areas and transfer water storage areas, forcing the fluid to form an S-shaped flow path in multiple pipes. The S-shaped flow prolongs the residence time of the fluid in the radiator and increases the heat exchange time. The coolant and circulating water are repeatedly divided and merged in multiple "transfer area-pipeline" units, achieving multiple local heat exchanges and improving the overall heat dissipation capacity.

[0031] The present invention enhances the heat dissipation performance of a radiator. Specifically, the laminar flow lower and upper water pipes are welded into a U-shaped structure using flat-end square tubes. Combined with an alternating stacking arrangement, these tubes form microchannels, which increase the contact area between the fluid and the tube wall (high surface-to-volume ratio) and enhance heat conduction. The flat-end design reduces the thickness of the fluid boundary layer, facilitating rapid heat transfer and achieving high heat dissipation density per unit volume, making it suitable for compact applications. The laminar flow lower pipe wall is stamped with turbulent grooves to disrupt the laminar flow state. These turbulent grooves generate turbulence during high-speed coolant flow, enhancing fluid mixing and thermal disturbance, and avoiding the "thickening of the thermal boundary layer" caused by laminar flow. The present invention also incorporates a corrugated heat dissipation strip to assist air heat dissipation. The strip is fixed within the pipe opening, directly contacting the pipe wall. It is mounted using clips to increase the external heat dissipation area. The corrugated structure expands the heat dissipation surface area, and heat is dissipated to the environment secondary to natural air convection or forced convection (e.g., through a fan), achieving a multi-stage "liquid-solid-gas" heat dissipation system.

[0032] This invention avoids heat backflow by optimizing heat distribution. Specifically, the overall heat distribution of the radiator is "high at the top and low at the bottom" (high temperature at the coolant inlet and low temperature at the outlet; low temperature at the circulating water inlet and high temperature at the outlet). The coolant temperature in the same area is always higher than the circulating water. Heat conduction is unidirectional (coolant → pipe wall → circulating water), avoiding reverse heat exchange and ensuring stable heat dissipation efficiency.

[0033] The present invention offers ease of maintenance and environmental adaptability. Specifically, the detachable dustproof module utilizes a U-shaped holder, L-shaped restraint block, and vertical grid to enable quick insertion and removal of the strip dust screen. The strip dust screen covers the outside of the corrugated heat dissipation belt, preventing dust accumulation and clogging of the belt. The detachable design simplifies cleaning and maintenance, reduces downtime, and is suitable for dusty environments. The heat dissipation capacity can be adjusted to match different heat load requirements by increasing or decreasing the number of laminar flow downpipes and laminar flow uppipes.

DETAILED DESCRIPTION

[0040] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0041] like Figures 1 to 4 As shown, an alternating stacked microchannel water-cooled radiator includes a square mounting plate frame 1, on both sides of which inner walls are welded and fixed a coolant tank 2 and a circulating water tank 3 of the same shape and size.

[0042] A plurality of laminar flow lower liquid pipes 4 and laminar flow upper water pipes 5 are provided between the coolant tank 2 and the circulating water tank 3 , and the plurality of laminar flow lower liquid pipes 4 and the plurality of laminar flow upper water pipes 5 are alternately stacked.

[0043] The laminar flow downpipe 4 is a U-shaped pipe with a transverse opening. The laminar flow downpipe 4 is welded by three sections of flat square pipes. The upper and lower ports of each laminar flow downpipe 4 are respectively connected to the coolant tank 2 .

[0044] Several horizontal liquid separation partitions 6 are provided from top to bottom in the coolant tank 2. The liquid separation partitions 6 are welded to the circumferential inner wall of the coolant tank 2. The liquid separation partitions 6 are arranged in a one-to-one correspondence with the laminar flow downpipe 4. The liquid separation partitions 6 are arranged between the upper and lower ports of the laminar flow downpipe 4, on the side close to the upper port.

[0045] Several liquid separation partitions 6 divide the interior of the coolant tank 2 into multiple transfer liquid storage areas 7. A liquid inlet pipe 8 is welded on the outer end surface of the coolant tank 2 near the upper part, and the liquid inlet pipe 8 is connected to the uppermost transfer liquid storage area 7. A liquid outlet pipe 9 is welded on the outer end surface of the coolant tank 2 near the lower part, and the liquid outlet pipe 9 is connected to the lowermost transfer liquid storage area 7.

[0046] The cooling liquid tank 2, the laminar flow down liquid pipe 4, the liquid inlet pipe 8 and the liquid outlet pipe 9 constitute an engine cooling liquid circuit of the radiator.

[0047] The left limiting block 10 is pressed between two adjacent laminar flow down liquid pipes 4 and is arranged close to the outer sidewall of the cooling liquid tank 2.

[0048] The corrugated heat dissipation band 12 is fixed in the transverse opening of each laminar flow down liquid pipe 4 and is arranged close to the upper and lower pipe walls of the laminar flow down liquid pipe 4.

[0049] The laminar flow down liquid pipe 4 is provided with the turbulence groove 14 on the upper and lower pipe walls close to the corrugated heat dissipation band 12.

[0050] The laminar flow up water pipe 5 is completely identical with the laminar flow down liquid pipe 4 in structure, shape and size.

[0051] The circulating water tank 3 is provided with the horizontal water distribution partition plate 15 from top to bottom.

[0052] The water distribution partition plate 15 separates the circulating water tank 3 into several intermediate water storage areas 16.

[0053] The fixed square frame 19 is welded in the middle of the outer end surface of the circulating water tank 3.

[0054] The circulating water tank 3, the laminar flow up water pipe 5, the water inlet pipe 17, the water outlet pipe 18 and the circulating water pump 20 constitute a circulating water circuit of the radiator.

[0055] The right limiting block 21 is pressed between two adjacent laminar flow up water pipes 5 and is arranged close to the outer sidewall of the circulating water tank 3.

[0056] A corrugated heat dissipation belt 12 is also fixed in the horizontal opening of each laminar water supply pipe 5. The corrugated heat dissipation belt 12 is arranged tightly against the upper and lower pipe walls of the laminar water supply pipe 5. Mounting clips 13 are also fixedly connected to the right support block 22 and the vertical outer wall of the laminar water supply pipe 5. The corrugated heat dissipation belt 12 is hung between the two mounting clips 13.

[0057] Two groups of detachable dustproof modules are respectively provided on the front and rear sides of the mounting plate frame 1, and each group of detachable dustproof modules includes two symmetrical U-shaped holders 23. The two U-shaped holders 23 are welded on the side end surface of the mounting plate frame 1 near the lower part, and two symmetrical L-shaped constraint blocks 24 are welded on the side end surface of the mounting plate frame 1 near the upper part. The L-shaped constraint blocks 24 are arranged opposite to the U-shaped holders 23 up and down.

[0058] A vertical grid 25 is installed in each U-shaped holder 23, and the upper end of the vertical grid 25 is clamped in the L-shaped constraint block 24. Several strip dustproof nets 26 are fixed between the two vertical grids 25. The strip dustproof nets 26 cover the outside of the corrugated heat dissipation belt 12 and are 5-10mm apart from the corrugated heat dissipation belt 12 to prevent dust accumulation without affecting air convection. The size of the strip dustproof nets 26 is larger than the opening size of the laminar lower liquid pipe 4 and the laminar upper water pipe 5.

[0059] When the present invention is used: first, the liquid inlet pipe 8 and the liquid outlet pipe 9 are respectively connected to the engine coolant pipeline, and 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 top transfer liquid storage area 7. The coolant first enters the laminar flow downpipe 4 in a forward direction, and after a reversal, it turns into a reverse return, so that the engine coolant flows into the next layer of transfer liquid storage area 7, and then flows into the next laminar flow downpipe 4 to perform the above-mentioned layered microchannel diversion. After multiple diversions, the coolant forms an S-shaped reciprocating laminar flow in multiple transfer liquid storage areas 7 and multiple laminar flow downpipes 4; start the circulating water pump 20, which provides the driving force for the directional flow of the circulating water: the low-temperature circulating water first enters the circulating water tank 3 through the water inlet pipe 17, and then is diverted to the next laminar flow downpipe 4. The bottom intermediate water storage area 16 enters the first laminar flow upper water pipe 5, and the circulating water first enters the laminar flow upper water pipe 5 in a forward direction, and is also converted into reverse return water after a reversal, and enters the intermediate water storage tank of the next layer, and then flows into the upper laminar flow upper water pipe 5 for the above-mentioned layered microchannel diversion, thereby forming an S-shaped reciprocating circulating water laminar flow in multiple intermediate water storage areas 16 and multiple laminar flow upper water pipes 5; because the two adjacent laminar flow lower liquid pipes 4 and the laminar flow upper water pipe 5 are superimposed and contacted, and when the high-temperature coolant in the laminar flow lower liquid pipe 4 is entering in a forward direction, the adjacent laminar flow upper water pipe 5 is also entering in a forward direction of low-temperature circulating water, and the directions of the forward liquid inflow and the forward water inflow are opposite, so in the process of forward liquid inflow and forward water inflow, the laminar flow lower liquid Countercurrent heat exchange occurs between the tube 4 and the laminar flow upper water pipe 5, and heat is transferred from the high-temperature coolant to the low-temperature circulating water through the solid, thereby realizing heat exchange and achieving the purpose of heat dissipation; the turbulent groove 14 arranged on the inner wall of the laminar flow lower liquid pipe 4 can disturb the coolant flow, forming turbulence, and preventing the problem of insufficient heat exchange time and poor heat exchange effect caused by the coolant flow rate being too fast; further, in the process of reverse liquid return and reverse water return, the flow direction of the coolant in the laminar flow lower liquid pipe 4 is also opposite to the flow direction of the circulating water in the laminar flow upper water pipe 5, which makes the coolant and the circulating water exchange heat through the contact between the laminar flow lower liquid pipe 4 and the laminar flow upper water pipe 5, whether in the process of liquid inlet and water outlet or liquid return and water return, thereby increasing the heat exchange area and achieving efficient heat dissipation; in addition, in the whole In each 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 upper water pipe 5 in the same area is always lower than the temperature of the coolant in the laminar lower liquid pipe 4, so that the heat can only be conducted from the coolant to the circulating water in a direction, and no reverse heat exchange occurs; the multiple corrugated heat dissipation belts 12 arranged in the radiator can dissipate heat into the air through direct contact with the laminar lower liquid pipe 4 and the laminar upper water pipe 5, and then take the heat away through air flow; the radiator is also provided with a sliding and detachable dustproof module, which includes several strip dustproof nets 26. The strip dustproof nets 26 are arranged on the outside of the corrugated heat dissipation belt 12, which can prevent the problem of reduced heat exchange efficiency of the corrugated heat dissipation belt 12 due to dust accumulation. The detachable design also facilitates subsequent cleaning and maintenance.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein, and 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 included in the scope of the claims and description of the present invention.
