Description

Technical Field

[0001] This utility model belongs to the technical field of heat exchange equipment, and relates to a radiator, specifically a plate-fin radiator. Background Technology

[0002] A radiator is a device that transfers heat generated by equipment to the external environment through conduction, convection, and radiation. Its core function is to maintain a stable equipment temperature and prevent performance degradation or damage caused by overheating. Currently, radiators can be classified into air-cooled radiators (such as finned radiators and plate-fin radiators), liquid-cooled radiators (such as water-cooled plate radiators), and heat pipe radiators, based on their heat dissipation methods and structural differences. Among these, plate-fin radiators are widely used in automobiles, air conditioning, and electronic equipment due to their high efficiency and compact design.

[0003] Plate-fin radiators are devices that achieve efficient heat dissipation by increasing the heat dissipation surface area and optimizing airflow paths. Their core function is to rapidly cool heat sources in electronic equipment, automotive systems, and industrial equipment to prevent overheating and subsequent system or equipment malfunctions. Structurally, they mainly consist of baffles, fins, seals, and chamber structures.

[0004] Because plate-fin radiators are made of metal, and the baffles need to be thickened to meet high pressure requirements; and the fins are usually designed as a highly dense array of metal fins (e.g., high-density fins with a thickness of 0.1mm to 0.5mm) or complex fin shapes (e.g., corrugated, louvered, etc.) to improve heat dissipation efficiency, the amount of metal used increases, the weight of the whole machine increases, and the cost increases. Summary of the Invention

[0005] The purpose of this invention is to provide a lightweight plate-fin radiator to solve the problems of excessive metal usage and heavy overall weight in existing plate-fin radiators.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] In one aspect, this utility model proposes a lightweight plate-fin radiator, comprising:

[0008] The plate bundle is composed of multiple sets of heat dissipation channels stacked together. Each set of heat dissipation channels includes an internal fluid channel, an outer fin, and a short seal.

[0009] The chamber comprises two sets, which are placed on opposite sides of the plate bundle and are respectively connected to the inlet and outlet of the internal fluid channel of each set;

[0010] Each group of chambers includes:

[0011] An outer cover extends along the stacking direction of the multiple heat dissipation channels and includes an outer end plate and two side plates. The two side plates have inner and outer sides in a relative position, and the outer sides are connected to the outer end plate.

[0012] An arc-shaped plate is located inside the outer cover and is the same length as the outer cover. Its two sides are respectively connected to the inner sides of the two side plates. The arc apex is connected to the outer end plate, and the rest is separated from the outer cover.

[0013] The sealing plate, whose shape is adapted to the shape of the arc end face of the arc plate, includes two, which are respectively sealed on the two arc end faces of the arc plate to form a cavity with one side open. The open side of the cavity is installed on the plate bundle.

[0014] A drainage tube is installed on the outer cover or sealing plate and connects to the cavity.

[0015] In some embodiments of this application, the central angle of the arc plate can be configured to be greater than 120° to increase the pressure-bearing capacity of the arc plate.

[0016] In some embodiments of this application, the two sets of chambers can be defined as a heat source chamber and a cold source chamber, respectively, based on the different temperatures of the fluids collected in the two chambers. The heat source chamber is installed on the inlet side of the internal fluid channel, with its drain pipe installed on the lower part of its outer cover or on the sealing plate at the bottom of its arc-shaped plate. This drain pipe is used to receive the high-temperature fluid to be cooled and introduce it into the internal fluid channel for heat dissipation. The cold source chamber is installed on the outlet side of the internal fluid channel, with its drain pipe installed on the upper part of its outer cover or on the sealing plate at the top of the arc-shaped plate. This drain pipe is used to collect the cooled low-temperature fluid flowing out of the internal fluid channel and discharge it through the drain pipe. Positioning the drain pipe of the heat source chamber at the lower part and the drain pipe of the cold source chamber at the upper part ensures that the high-temperature fluid to be cooled can be evenly distributed to each internal fluid channel, improving heat dissipation efficiency through multi-channel synchronous heat dissipation.

[0017] In some embodiments of this application, the outer end plate of the outer cover can be designed as a flat plate to facilitate the installation of large-sized fittings. The use of large-sized fittings can ensure the secure installation of the plate-fin radiator with other components.

[0018] In some embodiments of this application, the internal fluid channel includes inner fins arranged perpendicular to the arrangement direction of the outer fins, an upper partition plate installed on the top of the inner fins, a lower partition plate installed on the bottom of the inner fins, and a long sealing strip. The long sealing strip comprises two strips, respectively installed on opposite sides of the arrangement direction of the inner fins, with the other two sides of the inner fins forming the inlet and outlet of the internal fluid channel. A plurality of weight-reducing holes are formed on the long sealing strip, extending along its length and penetrating both opposite ends of the strip. By forming weight-reducing holes on the long sealing strip, the weight of the long sealing strip can be reduced, thereby achieving the purpose of reducing the overall weight of the plate-fin radiator.

[0019] In some embodiments of this application, the short sealing strip comprises two strips, respectively installed on opposite sides of the outer fin arrangement direction; a plurality of weight-reducing holes can be formed on the short sealing strip, and the weight-reducing holes are configured to extend along the length direction of the short sealing strip and penetrate through the opposite ends of the short sealing strip in the length direction. Forming weight-reducing holes on the short sealing strip can, on the one hand, reduce the weight of the short sealing strip, thereby further realizing the lightweight design of the plate-fin radiator; on the other hand, during ventilation and heat dissipation, cold air can partially pass through the weight-reducing holes on the short sealing strip, reaching the leeward side from the windward side of the plate bundle, thereby reducing the wind resistance generated by the configuration of the short sealing strip; simultaneously, when the cold air passes through the weight-reducing holes on the short sealing strip, it can carry away some heat, helping to improve the cooling efficiency of the plate bundle.

[0020] In another aspect, this utility model also proposes a chamber for a plate-fin radiator, comprising:

[0021] An outer cover includes an outer end plate and two side plates, the two side plates having inner and outer sides in a relative position, the outer sides being connected to the outer end plate;

[0022] An arc-shaped plate is located inside the outer cover and is the same length as the outer cover. Its two sides are respectively connected to the inner sides of the two side plates. The arc apex is connected to the outer end plate, and the rest is separated from the outer cover.

[0023] The sealing plate, whose shape is adapted to the shape of the arc end face of the arc plate, includes two, which are respectively sealed on the two arc end faces of the arc plate to form a cavity with one side open. The open side of the cavity is used to be installed on the plate bundle of the plate fin radiator to collect the high temperature fluid to be cooled or the low temperature fluid after cooling.

[0024] A drainage tube is installed on the outer cover or sealing plate and connects to the cavity.

[0025] In some embodiments of this application, the central angle of the arc plate can be configured to be greater than 120° to increase the pressure-bearing capacity of the arc plate and adapt to high-pressure fluids.

[0026] In some embodiments of this application, the two sets of chambers can be defined as a heat source chamber and a cold source chamber, respectively, based on the different temperatures of the fluids collected in them. The heat source chamber collects the high-temperature fluid requiring cooling, and its drain pipe is installed at the lower part of its outer casing or on the sealing plate at the bottom of its arc-shaped plate. The cold source chamber collects the cooled, low-temperature fluid, and its drain pipe is installed at the upper part of its outer casing or on the sealing plate at the top of its arc-shaped plate. Positioning the drain pipe of the heat source chamber at the lower part and the drain pipe of the cold source chamber at the upper part ensures that the high-temperature fluid requiring cooling can be evenly distributed to each internal fluid channel, achieving multi-channel synchronous heat dissipation and improving heat dissipation efficiency.

[0027] In some embodiments of this application, the outer end plate of the outer cover can be designed as a flat plate, on which several mounting accessories are installed. These accessories facilitate the installation of the plate-fin radiator onto other components. Because the outer end plate of the outer cover is flat, large-sized mounting accessories can be easily and securely installed on it. Using large-sized mounting accessories improves the stability and reliability of the connection between the plate-fin radiator and other components.

[0028] Compared with the prior art, the advantages and positive effects of this utility model are mainly reflected in:

[0029] 1. This utility model is designed to reduce the weight of the chamber of a plate-fin radiator. By reducing the amount of metal used in the chamber, a lightweight design of the plate-fin radiator is achieved without affecting its heat dissipation efficiency and pressure bearing capacity, thus saving costs.

[0030] 2. This utility model designs the outer cover as a U-shaped structure, and uses an arc plate to construct the chamber of the plate-fin radiator. By configuring the arc plate, only its arc top and two sides are connected to the outer cover, while the rest are separated from the outer cover to form a weight-reducing cavity. Therefore, compared with the chamber made of a single piece of metal, it is lighter in weight, can maintain the original welding surface, and is convenient for replacing and modifying the chamber of the existing plate-fin radiator.

[0031] 3. This utility model uses an arc-shaped plate and a sealing plate to form a cavity for collecting high-temperature fluids that need to be cooled or low-temperature fluids that have been cooled. By increasing the central angle of the arc-shaped plate, the pressure-bearing capacity of the chamber can be improved, so that the lightweight plate-fin radiator can also adapt to the situation where the medium to be cooled is a high-pressure fluid.

[0032] 4. This utility model designs the outer cover of the chamber as a flat-bottomed U-shaped structure, which makes it easy to install large-sized accessories on the outer cover, thereby ensuring the firmness of the assembly of the plate-fin radiator with other components.

[0033] 5. In addition to the lightweight design of the chamber of the plate-fin radiator, this utility model further lightweights the long and short sealing strips of the plate-fin radiator. By creating through holes extending along the length of the sealing strips on both the long and short strips, weight-reducing holes are formed, thereby reducing the individual weight of each long and short sealing strip. Since the plate-fin radiator contains a large number of long and short sealing strips, reducing the weight of all long and short sealing strips further reduces the overall weight of the plate-fin radiator.

[0034] After reading the detailed embodiments of this utility model in conjunction with the accompanying drawings, other features and advantages of this utility model will become clearer. Attached Figure Description

Detailed Implementation

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0052] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or internal communication within components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. In the description of the embodiments, specific features, structures, materials, or characteristics can be combined in any suitable manner in one or more embodiments or examples.

[0053] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0054] Combination Figures 1 to 8 As shown, the plate-fin radiator 100 of this embodiment mainly consists of partitions 410 and 420, inner fins 430, outer fins 310, long seals 440 and 450, short seals 320 and 330, and a chamber 500. Specifically, by arranging the inner fins 430 between the two partitions 410 and 420, and installing long seals 440 and 450 on opposite sides of the inner fins 430's arrangement direction, an internal fluid channel 400 is formed. The other two sides of the inner fins 430 are open, forming an inlet 401 and an outlet 402 of the internal fluid channel 400, through which high-temperature fluid requiring cooling can pass. Outer fins 310 are arranged on the top of the upper partition 410 above the inner fins 430 or on the bottom of the lower partition 420 below the inner fins 430, with the arrangement direction of the outer fins 310 perpendicular to the arrangement direction of the inner fins 430. Then, a short sealing strip 320 and 330 are installed on opposite sides of the arrangement direction of the outer fins 310, thus forming a set of heat dissipation channels 300. Multiple sets of such heat dissipation channels 300 are configured, stacked one on top of the other, and brazed into a whole to form the plate bundle 200. A chamber 510 and a chamber 520 are respectively arranged on opposite sides of the plate bundle 200 (on the sides where the inlet 401 and outlet 402 of the internal fluid channel 400 are located), which are connected to the inlet 401 and outlet 402 of each set of internal fluid channels 400. An upper cover plate 110 is installed on the top of the plate bundle 200 and a lower cover plate 120 is installed on the bottom of the plate bundle 200, thus forming a plate-fin radiator 100.

[0055] When using the plate-fin radiator of this embodiment to dissipate heat from a high-temperature fluid (water, oil, gas, etc.), the high-temperature fluid is first introduced into the heat source chamber 510 (i.e., the chamber connected to the inlet side of the internal fluid channel 400). After being collected by the heat source chamber 510, the fluid is evenly distributed to each group of internal fluid channels 400. As the high-temperature fluid passes through the internal fluid channel 400, the inner fins 430 evenly diffuse the heat of the high-temperature fluid to the entire upper baffle 410 and lower baffle 420, and then transfer it to the surface of the outer fins 310 arranged thereon via the upper baffle 410 and lower baffle 420, thereby significantly expanding the heat dissipation area. Then, the heat on the surface of the outer fins 310 is carried away by natural convection (driven by air temperature difference) or forced convection (driven by fan), achieving cooling. The cooled low-temperature fluid flows out through the outlet 402 of the internal fluid channel 400 and gathers in the cold source chamber 520 (i.e., the chamber connected to the outlet side of the internal fluid channel 400). Finally, it is collected in the cold source chamber 520 and discharged, completing the entire heat dissipation process.

[0056] Since the entire plate-fin radiator 100 is basically made of metal materials such as aluminum or steel, it is heavy, expensive, and not conducive to handling and installation.

[0057] To address the aforementioned issues, this embodiment focuses on three aspects: the chamber 500, the long seals 440 and 450, and the short seals 320 and 330. The plate-fin radiator 100 is designed to be lightweight, minimizing its overall weight and reducing costs.

[0058] For the chamber 500 of the plate-fin radiator 100, combined with Figures 9 to 11 As shown, this embodiment uses a weight-reducing cavity design to achieve a lightweight chamber 500.

[0059] Existing plate-fin radiators typically form their housings by carving grooves into a single piece of metal. To meet pressure resistance requirements, the housing thickness is usually significant, resulting in high metal consumption, high cost, and heavy weight. To balance lightweight design with pressure resistance, some plate-fin radiators have designed their housings as a single, rounded arc. While this saves metal usage while maintaining pressure resistance, it introduces problems such as the inability to install large-sized components and unsuitability for welding on the existing welding surfaces of the plate bundle 200mm.

[0060] To meet the design requirements of lightweight chamber, high pressure resistance, easy installation of large-size components, and maintaining the original welding surface on the plate bundle, this embodiment designs the chamber 500 as follows: Figure 9 The structure shown mainly includes an outer cover 530, an arc-shaped plate 540, and a sealing plate 550 (combined with...). Figure 3 It consists of components such as the drainage tube 560, as shown in the figure.

[0061] The outer cover 530 can be designed as a U-shaped structure, including an outer end plate 533 and two side plates 531 and 532. In some embodiments, the outer end plate 533 and the two side plates 531 and 532 can be designed as long strips, the length of which is adapted to the stacking height of each group of heat dissipation channels 300 in the plate bundle 200. The two long sides of the two side plates 531 and 532 that extend along their length direction and are positioned opposite each other are defined as the inner side and the outer side. The outer sides of the two side plates 531 and 532 are respectively connected to the two long sides of the outer end plate 533, and the inner side extends away from the outer end plate 533 to form a flat-bottomed U-shaped structure.

[0062] Of course, the outer cover 530 can also be integrally formed, and this embodiment does not impose specific restrictions on this.

[0063] Since the outer cover 530 does not need to withstand fluid pressure, the metal plate used does not need to be too thick. By controlling the weight of the outer cover 530, the overall weight of the chamber 500 can be reduced.

[0064] An arc-shaped plate 540 is disposed within the groove formed by the outer cover 530. The length of the arc-shaped plate 540 is equal to the length of the outer cover 530, and includes two side edges 541 and 542 extending along the length direction of the arc-shaped plate 540, as well as two arc-shaped end faces 543. The two side edges 541 and 542 of the arc-shaped plate 540 are respectively connected to the inner side edges of the two side plates 531 and 532 of the outer cover 530, and the arc apex 544 of the arc-shaped plate 540 is connected to the outer end plate 533 of the outer cover 530. The remaining part of the arc-shaped plate 540 is separated from the outer cover 530, and the separated area forms a weight-reducing cavity 545. Compared with the existing chambers that use grooves carved into a single piece of metal, the amount of metal material used is significantly reduced, thus reducing weight and cost.

[0065] In some embodiments, the two side plates 531 and 532 of the outer cover 530 can be configured to be perpendicularly connected to the outer end plate 533, that is, to make the weight reduction cavity 545 form a cavity with right angles, similar to a right-angled triangle, such as... Figure 10 As shown, this ensures that the volume of the weight-reducing cavity 545 is maximized, so as to better achieve the lightweight of the chamber 500.

[0066] Since the shape of the outer cover 530 is consistent with the shape of the existing chamber, when welding the chamber 500 to the plate bundle 200, the welding operation can be performed on the original welding surface of the plate bundle 200. This not only facilitates assembly, but also makes it easy to replace the existing chamber on the old product, so as to achieve lightweight design on the old product.

[0067] In addition, since the outer end plate 533 of the outer cover 530 is a flat plate, large-sized fittings 534 can be easily installed on it. This not only ensures the stability of the fittings 534 on the outer end plate 533, but also improves the sturdiness of the plate-fin radiator 100 with other components by using large-sized fittings 534.

[0068] In some embodiments, two cylindrical fittings 534 may be installed on the outer end plate 533 of each chamber 500, such as... Figure 9 As shown, the two cylindrical fittings 534 are arranged at intervals along the length of the outer end plate 533. By adopting a multi-point force distribution method, the reliability of the plate-fin radiator 100 and other components can be improved.

[0069] In order for the plate-fin radiator 100 of this embodiment to dissipate heat from high-pressure fluids, the arc-shaped plate 540 needs to have a large curvature to achieve pressure resistance. In some embodiments, the central angle of the arc-shaped plate 540 can be designed to be greater than 120°. For example, the arc-shaped plate 540 can be designed as a semi-circular plate. By increasing the pressure-bearing capacity of the chamber 500, the applicable scenarios of the plate-fin radiator 100 can be expanded.

[0070] Sealing plates 550 are installed at the two arc-shaped end faces 543 of the arc-shaped plate 540, respectively, in combination with Figure 3 As shown, by sealing both ends of the arc-shaped plate 540, a cavity 551 with only one side open is formed, which is used to collect high-temperature fluid that needs to be dissipated or low-temperature fluid after dissipation.

[0071] In some embodiments, the shape of the sealing plate 550 can be configured to match the shape of the arc-shaped end face 543 of the arc-shaped plate 540. For example, for an arc-shaped plate 540 with a semi-circular end face, the sealing plate 550 can be designed as a semi-circle and installed at both ends of the arc-shaped plate 540 to form a semi-cylindrical cavity 551. The opening sides of the semi-cylindrical cavities 551 of the two chambers 500 face the plate bundle 200. One chamber is installed on the inlet side of the internal fluid channel 400, and its semi-cylindrical cavity 551 is used to collect the high-temperature fluid that needs to be dissipated, which can be called the heat source chamber 510. The other chamber is installed on the outlet side of the internal fluid channel 400, and its semi-cylindrical cavity 551 is used to collect the low-temperature fluid after dissipation, which can be called the cold source chamber 520. The length of the two chambers 500 is parallel to the stacking direction of the heat dissipation channels 300 in the plate bundle 200, and the length of the chambers 500 is basically the same as the stacking height of each group of heat dissipation channels 300 in the plate bundle 200. This ensures that the cavity 551 is connected to all the internal fluid channels 400 in the plate bundle 200. By utilizing all the heat dissipation channels 300 to simultaneously dissipate heat from the high-temperature fluid, the heat dissipation efficiency of the plate-fin radiator 100 can be improved.

[0072] To introduce high-temperature fluid requiring heat dissipation into the heat source chamber 510 or to discharge cooled low-temperature fluid from the cold source chamber 520, this embodiment configures drainage pipes 560 on each of the two chambers, combined with... Figure 3 , Figure 9 As shown. The drainage pipe 561 of the heat source chamber can be configured at the lower part of the outer cover 530 of the heat source chamber 510, such as... Figure 3 The positional relationship shown is such that it passes through the outer cover 530 and the arc plate 540 of the heat source chamber and directly connects to the cavity 551 of the heat source chamber, as shown. Figure 11 As shown. Alternatively, the drain pipe 561 of the heat source chamber can be installed on the sealing plate 550 located at the bottom of the arc-shaped plate 540 of the heat source chamber, and connected to the cavity 551 of the heat source chamber. Correspondingly, the drain pipe 562 of the cold source chamber can be configured on the upper part of the outer cover 530 of the cold source chamber 520, such as... Figure 3 The positional relationship shown is such that the tube passes through the outer cover 530 and the arc plate 540 of the cold source chamber and is directly connected to the cavity 551 of the cold source chamber; or, the drain pipe 562 of the cold source chamber can be installed on the cover plate 550 located at the top of the arc plate 540 of the cold source chamber and connected to the cavity 551 of the cold source chamber.

[0073] In this embodiment, the drain pipe 561 of the heat source chamber is positioned below the heat source chamber 510, and the drain pipe 562 of the cold source chamber is positioned above the cold source chamber 520. This configuration ensures that the high-temperature fluid entering the heat source chamber 510 can fill the entire heat source chamber 510, and then be evenly distributed to each internal fluid channel 400, so that all heat dissipation channels 300 in the plate bundle 200 can participate in heat dissipation, thereby accelerating the heat dissipation rate. The fluid passing through the plate bundle 200 has a lower temperature, forming a low-temperature fluid, which flows out through the outlet 402 of each group of internal fluid channels 400 and collects in the cold source chamber 520. After the low-temperature fluid fills the cavity 551 of the cold source chamber 520, it is discharged through the drain pipe 562 at the top of the cold source chamber and enters the subsequent system.

[0074] In this embodiment, the chamber 500 achieves a lightweight design while retaining the shape of an existing plate-fin radiator chamber. Therefore, it allows for easy replacement of the original chamber on existing plate-fin radiators, completing the lightweight transformation of the plate-fin radiator. Furthermore, by designing a large-radius curved plate 540 within the chamber 500, the pressure resistance of the existing plate-fin radiator can be maintained, achieving a balance between lightweight design and pressure resistance.

[0075] To further reduce the overall weight of the plate-fin radiator 100, this embodiment incorporates a lightweight design for the long seals 440 and 450, combined with... Figure 5 , Figure 8 , Figure 12As shown. In each group of internal fluid channels 400, two long sealing strips 440 and 450 are arranged on opposite sides of the inner fins 430, with their lengths being approximately the same as the overall length of the plate bundle 200, as shown. Figure 4 As shown, the other two sides of the inner fins 430 form the inlet 401 and outlet 402 of the internal fluid channel 400. Since multiple sets of such internal fluid channels 400 are stacked in the plate bundle 200, a large number of long seals 440 and 450 are used. By reducing the individual weight of each long seal 440 and 450, the overall weight of the plate-fin radiator 100 can be significantly reduced.

[0076] In order to achieve weight reduction in the long seals 440 and 450, this embodiment provides one or more large-sized through holes 441 in the long seals 440 and 450. The through holes 441 are configured to extend along the length of the long seals 440 and 450 and penetrate the opposite ends of the long seals 440 and 450 in the length direction, thereby forming weight-reducing holes and achieving the purpose of reducing the weight of the long seals 440 and 450 individually.

[0077] Similarly, for the short sealing strips 320 and 330 arranged on opposite sides of the outer fin 310, combined with Figure 4 , Figure 6 , Figure 13 As shown, large or multiple small through holes 331 can be made on each short seal 320, 330. The through holes 331 are configured to extend along the length direction of the short seal 320, 330 and penetrate the opposite ends of the short seal 320, 330 in the length direction, thereby forming weight-reducing holes to reduce the weight of the short seal 320, 330.

[0078] Since two short sealing strips 320 and 330 are arranged on opposite sides of each outer fin 310, and their lengths are basically consistent with the overall width of the plate bundle 200, such as Figure 5 As shown, multiple sets of such outer fins 310 are stacked in the plate bundle 200, so a large number of short seals 320 and 330 are used. By reducing the individual weight of each short seal 320 and 330, the overall weight of the plate bundle 200 can be significantly reduced, making the plate-fin radiator 100 even lighter.

[0079] Furthermore, since the weight reduction holes 331 are located on the windward and leeward ends of the short seals 320 and 330, and their extension direction is consistent with the flow direction of the cooling air blowing towards the outer fins 310, when the cooling fan blows air to the plate-fin radiator 100, the weight reduction holes 331 can not only reduce wind resistance, but also carry away some heat and accelerate heat dissipation as the cooling air flows through the weight reduction holes 331.

[0080] Industrial applicability

[0081] The plate-fin radiator of this embodiment is applied to engineering vehicles to cool the hydraulic oil circulating in the hydraulic system of the engineering vehicles.

[0082] During operation, high-temperature and high-pressure hydraulic oil is first injected into the heat source chamber 510 of the plate-fin radiator 100 through the diversion pipe 561. After being collected by the heat source chamber 510, it enters the inlet 401 of each group of internal fluid channels 400 under the action of oil pressure and flows to the outlet 402 of the internal fluid channel 400.

[0083] As the high-temperature, high-pressure hydraulic oil flows through the internal fluid channels 400 of the plate-fin radiator 100, the inner fins 430 in the internal fluid channels 400 evenly diffuse the heat of the hydraulic oil to the entire upper baffle 410 and lower baffle 420, and then transfer it to the surface of the outer fins 310 via the upper baffle 410 and lower baffle 420. The cooling air blown out by the cooling fan flows perpendicular to the arrangement direction of the outer fins 310, carrying away the heat from the surface of the outer fins 310 on one hand, and passing through the weight-reducing holes 331 on the short seals 320 and 330 to assist in heat dissipation.

[0084] After cooling, the hydraulic oil's temperature decreases, forming low-temperature, high-pressure hydraulic oil. It flows out through the outlet 402 of each group's internal fluid channel 400, collects in the cold source chamber 510 of the plate-fin radiator 100, and returns to the hydraulic system through the drain pipe 562 of the cold source chamber, completing the cooling process.

[0085] The plate-fin radiator of this embodiment has a compact and lightweight structure, high cost performance, and is especially suitable for industrial applications that balance heat dissipation efficiency and space constraints.
