After the compressed air enters the cooling connector, it can pass through the outer fin layer of the oil cooler or the outer fin layer of the air cooler along the angle between the flow divider and the outer fins of the oil cooler or the air cooler, thereby controlling the windward angle of the oil cooler and the air cooler and stabilizing the heat dissipation effect of the oil and air coolers.

This makes it easier to install and use the oil and air radiator in relatively narrow vertical spaces. Furthermore, by setting baffles and diverter plates in the cooling connector, compressed air can pass through the outer fin layer along the angle between the diverter plate and the outer fin surface of the oil cooler or the outer fin surface of the air cooler, thereby controlling the windward angle of the oil cooler and air cooler and stabilizing the heat dissipation effect of the oil and air cooler.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0030] Example 1:

[0031] like Figures 1-3 As shown, Embodiment 1 of this utility model provides a dual-inlet dual-outlet anti-corrosion oil-air radiator, which includes an oil cooler 1, an air cooler 2, and a cooling connector 3.

[0032] The cooling connector 3 is hollow inside; both the left and right sides of the cooling connector 3 are provided with mounting connection ports 31; the mounting connection ports 31 are connected to the internal space of the cooling connector 3; the outer fins of the oil cooler 1 are attached and fixed to the left side of the cooling connector 3; the outer fins of the air cooler 2 are attached and fixed to the right side of the cooling connector 3.

[0033] The cooling connector 3 has a partition 32 inside; the partition 32 is vertically arranged; the partition 32 is in close contact with the inner wall of the cooling connector 3; the surface of the partition 32 is perpendicular to the front side of the cooling connector 3; the partition 32 is located at the center of the cooling connector 3.

[0034] Several flow dividers 321 are provided on both the left and right sides of the partition plate 32; the flow dividers 321 are vertically arranged; the flow dividers 321 are in close contact with the inner wall of the cooling connector 3; the flow dividers 321 are in close contact with the outer fin surface of the oil cooler 1; the flow dividers 321 are in close contact with the outer fin surface of the air cooler 2; several vent holes 3211 are provided on the flow dividers 321.

[0035] Two air inlets 33 are provided on the front side of the cooling connector 3; the two air inlets 33 are located on both sides of the partition 32; the air inlets 33 are connected to the internal space of the cooling connector 3.

[0036] The oil cooler 1 and gas cooler 2 in the dual-inlet dual-outlet anti-corrosion oil-gas radiator of this utility model embodiment 1 adopt the structure of a plate-fin heat exchanger without long seals disclosed in Chinese Patent No. 202321157014.5; wherein the oil cooler 1 further includes an oil inlet head 101 and an oil outlet head 102, which are respectively disposed at the short seals on both sides of the plate-fin heat exchanger; the gas cooler 2 further includes an air inlet head 201 and an air outlet head 202, which are respectively disposed at the short seals on both sides of the plate-fin heat exchanger.

[0037] When using the dual-inlet, dual-outlet anti-corrosion oil-air radiator provided in Embodiment 1 of this utility model, the oil inlet channel is connected to the oil inlet end cap 101, and the oil outlet channel is connected to the oil outlet end cap 102; the air inlet channel is connected to the air inlet end cap 201, and the air outlet channel is connected to the air outlet end cap 202; the output end of the compressed air is connected to the two air inlets 33; the compressed air enters the internal space of the cooling connector 3 from the air inlets 33, and enters the space on both sides separated by the partition 32, and is guided by the diverter plate 321 to the outer fin layer on the oil cooler 1 and the air cooler 2; furthermore... Compressed air passes through the vent 3211 on the manifold 321, moves to the next manifold 321, and continues until it reaches the rear side of the cooling connector 3. The compressed air passes through the outer fin layer on the oil cooler 1 and the air cooler 2, and is discharged outside the oil-air radiator. The hot oil medium and the hot gas medium enter from the oil inlet head 101 and the air inlet head 201, respectively, pass through the inner fin layer 120, and are cooled by the compressed air. The oil medium and the gas medium leave from the oil outlet head 102 and the air outlet head 202, respectively. The oil medium enters the oil outlet channel, and the gas medium enters the air outlet channel.

[0038] The dual-inlet, dual-outlet corrosion-resistant oil-air radiator provided in Embodiment 1 of this utility model includes an oil cooler 1, an air cooler 2, and a cooling connector 3. The oil cooler 1 and the air cooler 2 are connected by the cooling connector 3. Specifically, the left and right sides of the cooling connector 3 are provided with mounting connection ports 31. The outer fins of the oil cooler 1 are attached and fixed to the left side of the cooling connector 3, and the outer fins of the air cooler 2 are attached and fixed to the right side of the cooling connector 3. This allows the oil cooler 1 and the air cooler 2 to be arranged side by side, reducing the space occupied by the oil-air radiator in the vertical direction, and thus facilitating the installation and use of the oil-air radiator in relatively narrow vertical spaces.

[0039] To achieve simultaneous cooling of oil cooler 1 and air cooler 2, two air inlets 33 are provided on the front side of the cooling connector 3. A partition 32 is installed inside the cooling connector 3, dividing it into two parts. The two air inlets 33 are located on opposite sides of the partition 32, allowing compressed air entering the cooling connector 3 to independently cool and dissipate heat from the oil cooler 1 and air cooler 2, preventing cross-flow of compressed air within the cooling connector 3 and improving the cooling effect of the oil cooler 1 and air cooler 2. To avoid the airflow angle of the oil-air cooler affecting its heat dissipation effect, a partition 32 is located on the left side of the partition 32. Several flow dividers 321 are provided on both right side plates. The flow dividers 321 are in close contact with the outer fins of the oil cooler 1 and the outer fins of the air cooler 2. After the compressed air enters the cooling connector 3, it can pass through the outer fin layer of the oil cooler 1 or the outer fin layer of the air cooler 2 along the angle between the flow divider 321 and the outer fins of the oil cooler 1 or the air cooler 2, thereby controlling the windward angle of the oil cooler 1 and the air cooler 2 and stabilizing the heat dissipation effect of the oil and air coolers. Furthermore, several vent holes 3211 are provided on the flow divider 321 to allow compressed air to circulate in the cooling connector 3.

[0040] Existing technologies stack oil coolers and air coolers vertically, occupying a large space in the vertical direction, which is not conducive to the installation and use of oil and air coolers. Moreover, after installation, the orientation angle of the windward side of the oil and air cooler can easily affect its heat dissipation effect. The dual-inlet dual-outlet corrosion-resistant oil and air radiator provided in Embodiment 1 of this utility model connects oil cooler 1 and air cooler 2 through cooling connector 3, so that oil cooler 1 and air cooler 2 are arranged side by side, thereby reducing the space occupied by the oil and air radiator in the vertical direction, and thus facilitating the installation and use of the oil and air radiator in relatively narrow vertical spaces. Furthermore, by setting baffle 32 and flow divider 321 in the cooling connector 3, compressed air can pass through the outer fin layer along the angle between the flow divider 321 and the outer fin surface of oil cooler 1 or air cooler 2, thereby controlling the windward angle of oil cooler 1 and air cooler 2, and thus stabilizing the heat dissipation effect of oil and air cooler.

[0041] like Figure 1As shown, the dual-inlet, dual-outlet corrosion-resistant oil-air radiator provided in Embodiment 1 of this utility model preferably features a compressed air intake from the front side of the cooling connector 3. Due to the obstruction of the diverter plate 321, the compressed air is reduced as it passes through the vent holes 3211 on the diverter plate 321. Therefore, it is necessary to rapidly cool the oil cooler 1 and the air cooler 2 at the front end of the cooling connector 3. Specifically, the cross-section of the cooling connector 3 is made into an isosceles trapezoid, forming a frustum shape. The upper bottom surface of the cooling connector 3 is used as the front side. The oil cooler 1 and the air cooler 2 are inclined, which reduces the distance between the oil cooler 1 and the air cooler 2 and the partition plate 32. This reduces the distance that the compressed air needs to travel to the oil cooler 1 or the air cooler 2 due to the obstruction of the diverter plate 321, thereby increasing the cooling rate of the compressed air to the oil cooler 1 and the air cooler 2. Furthermore, the oil inlet end cap 101 of the oil cooler 1 and the air inlet end cap 201 of the air cooler 2 are located on the side close to the front side of the cooling connector 3, so that the hotter medium at the front end of the inner fin layer 120 can be cooled better, thereby improving the heat dissipation effect of the oil-air cooler.

[0042] like Figures 1-2As shown, the dual-inlet, dual-outlet corrosion-resistant oil-air radiator provided in Embodiment 1 of this utility model preferably has different flow rates of the heat medium in the oil cooler 1 and the air cooler 2, and different structures of the inner fin layer 120 or outer fin layer in the oil cooler 1 and the air cooler 2. These factors affect the heat dissipation rate of the oil-air radiator. In order to obtain the best heat dissipation efficiency of the oil-air radiator, it is necessary to adjust the angle between the diverter plate 321 and the outer fin surface of the oil cooler 1 or the outer fin surface of the air cooler 2. Specifically, the diverter plate 321 is elastic, so that the diverter plate 321 abuts against the outer fin surface of the oil cooler 1 or the outer fin surface of the air cooler 2. The length of the diverter plate 321 is longer than the length from the partition plate 32 to the outer fin surface of the oil cooler 1 or the outer fin surface of the air cooler 2, so that different angles can be formed when the diverter plate 321 contacts and is pressed against the outer fin surface of the oil cooler 1 or the outer fin surface of the air cooler 2. Further, in order to achieve control The position of the flow divider 321 relative to the outer fins of the oil cooler 1 or the air cooler 2 is determined. The front and rear sides of the cooling connector 3 are provided with extension openings 34 for the partition 32 to extend out of the cooling connector 3. The partition 32 is fitted into the extension openings 34 and extends out of the cooling connector 3. The partition 32 moves in the front-rear direction, causing the flow divider 321 to move. Since the flow divider 321 abuts against the outer fins of the oil cooler 1 or the air cooler 2, and the flow divider 321 is elastic, there is frictional resistance between the flow divider 321 and the oil cooler 1 or the air cooler 2. This frictional resistance can change the angle or direction of the angle between the flow divider 321 and the outer fins of the oil cooler 1 or the air cooler 2. More specifically, when the partition 32 moves forward, the flow divider 321 tilts backward; when the partition 32 moves backward, the flow divider 321 tilts forward.

[0043] like Figures 1-2 As shown, the dual-inlet, dual-outlet anti-corrosion oil-gas radiator provided in Embodiment 1 of this utility model preferably includes a cylinder 35 in order to control the movement of the partition 32 in the front-back direction; the cylinder 35 is fixed on the rear side of the cooling connector 3; the telescopic rod of the cylinder 35 is fixed to the partition 32; the telescopic shaft of the cylinder 35 faces forward; when the cylinder 35 extends, the partition 32 moves forward; when the cylinder 35 retracts, the partition 32 moves backward.

[0044] like Figure 4 As shown, the dual-inlet and dual-outlet anti-corrosion oil-gas radiator provided in Embodiment 1 of this utility model preferably includes an oil cooler 1 and a gas cooler 2, each comprising a plurality of inner fin layers 120 and a plurality of outer fin layers; the inner fin layers 120 and the outer fin layers are alternately arranged, as shown in the heat exchanger structure in Chinese Patent No. 202321157014.5.

[0045] Specifically, the inner fin layer 120 includes an inner fin 1201, an upper core plate 1202, a lower core plate 1203, a left sealing strip 1204, and a right sealing strip 1205; the inner fin 1201, the left sealing strip 1204, and the right sealing strip 1205 are located between the upper core plate 1202 and the lower core plate 1203; the inner fin 1201 is located between the left sealing strip 1204 and the right sealing strip 1205; the top of the left sealing strip 1204 is fixed to the bottom surface of the upper core plate 1202; the bottom of the right sealing strip 1205 is fixed to the top surface of the lower core plate 1203.

[0046] To ensure the oil-gas radiator has good corrosion resistance, the upper core plate 1202 includes a first aluminum plate 12021, a first metal composite plate 12022, and several first fasteners 12023. The first aluminum plate 12021 is located above the first metal composite plate 12022. The top of the first fastener 12023 is fixed to the top of the first aluminum plate 12021, and the bottom of the first fastener 12023 is fixed to the top of the first metal composite plate 12022. The gap between the first aluminum plate 12021 and the first metal composite plate 12022 is sealed to form the upper core plate 1202.

[0047] The lower core plate 1203 includes a second aluminum plate 12031, a second metal composite plate 12032, and a plurality of second fasteners 12033; the second aluminum plate 12031 is located below the second metal composite plate 12032; the top of the second fastener 12033 is fixed to the bottom of the second metal composite plate 12032; the bottom of the second fastener 12033 is fixed to the top of the second aluminum plate 12031; the gap between the second aluminum plate 12031 and the second metal composite plate 12032 is sealed to form the lower core plate 1203;

[0048] When the heat medium flows in the inner fin layer 120, it flows between the upper core plate 1202 and the lower core plate 1203. The heat medium first contacts the first metal composite plate 12022 and the second metal composite plate 12032. Compared with the aluminum plate, the first metal composite plate 12022 and the second metal composite plate 12032 have better corrosion resistance and can protect the outer first aluminum plate 12021 and the second aluminum plate 12031, preventing the first aluminum plate 12021 and the second aluminum plate 12031 from being directly corroded by the heat medium, thus preventing the heat medium from flowing out. Furthermore, the first fastener 12023 connects the first aluminum plate 12021 and the first metal composite plate 12032. The composite plate 12022 and the second fastener 12033 connect the second aluminum plate 12031 and the second metal composite plate 12032, so that there are gaps between the first aluminum plate 12021 and the first metal composite plate 12022, and between the second aluminum plate 12031 and the second metal composite plate 12032. If the first metal composite plate 12022 or the second metal composite plate 12032 is corroded and perforated by the hot medium, by setting the gap, the hot medium can be prevented from contacting the same position in the vertical direction, so that the hot medium can continue to corrode the metal composite plate or corrode the aluminum plates in different vertical directions, thereby extending the service life of the upper core plate 1202 and the lower core plate 1203.

[0049] Furthermore, metals with different corrosion rates can be filled into the gaps to slow down the corrosion of the upper core plate 1202 and the lower core plate 1203.

[0050] In summary, the dual-inlet, dual-outlet corrosion-resistant oil-gas radiator provided by this utility model can solve the problems of existing technologies where oil coolers and gas coolers are stacked vertically, occupying a large space in the vertical direction, which is not conducive to the installation and use of oil-gas coolers, and the orientation angle of the windward side of the oil-gas cooler affects the heat dissipation effect of the oil-gas cooler. It can reduce the space occupied by the oil-gas radiator in the vertical direction and enhance the heat dissipation effect of the oil-gas radiator.
