In the case where the structures of the water cooler, the air cooler, and the oil cooler are the same, any one of the coolers is composed of a partition, a seal, a fin, and the like.

Example 1

The exposed weld at the first fluid inlet end can increase the potential for fluid leakage at the weld under long-term impact. In order to solve the above technical problems, embodiment 1 provides a wetland bulldozer oil water-gas three-phase combination cooler 01, as shown in fig. 2 to 7, which includes a first seal head 1 and a heat exchanger core 2; the heat exchanger core 2 comprises a plurality of first fluid inlets 201 arranged at intervals; all the first fluid inlets 201 are arranged in the inner cavity of the first seal head 1; the end surface of the heat exchanger core 2 where all the first fluid inlets 201 are located is a first fluid inlet end 20; a baffle plate 10 is arranged in the first seal head 1; one of the faces 101 of the baffle 10 is in close proximity to the first fluid inlet end 20; the baffle 10 is provided with a plurality of through type pore channels 102; the extension direction of the pore canal 102 is vertical to the plate surface 101; the pore canal 102 is respectively communicated with the inner cavity of the first seal head 1 and the first fluid inlet 201, and the pore canal 102 and the first fluid inlet 201 are arranged in a one-to-one correspondence manner; the baffle 10 completely covers the remaining portion of the first fluid inlet end 20 except for all of the first fluid inlets 201 (see fig. 7). The wetland bulldozer oil water-gas three-phase combination cooler 01 provided in embodiment 1 is characterized in that the baffle plate 10 is disposed at the first fluid inlet end 20, and the welding seams between the partition plate 001 and the seal 002 and between the partition plate 001 and the fins 003 are shielded by the integrated structure of the baffle plate 10, so that the first fluid can impact the baffle plate 10 to change the direction of the first fluid particles when flowing through the first fluid inlet end 20, and enter the first fluid channel through the first fluid inlet 201. Therefore, the direct impact of the first fluid on the welding seam is avoided, and the risk of fluid leakage at the welding seam is greatly reduced. Due to the simple structure of the baffle 10, the baffle is convenient to integrally machine and form, so that the baffle is relatively unlikely to crack even if the baffle faces strong direct impact for a long time. By arranging the plurality of the holes 102 on the baffle 10, each hole 102 is correspondingly arranged with one first fluid inlet 201, the holes 102 are respectively communicated with the inner cavity of the first seal head 1 and the first fluid inlets 201, on the premise of protecting welding lines, effective communication between each first fluid inlet 201 and the inner cavity of the first seal head 1 is realized, and the heat exchange efficiency of the wetland bulldozer oil water-gas three-phase combined cooler is basically equivalent to that of the traditional wetland bulldozer oil water-gas three-phase combined cooler.

It should be understood that when the wetland bulldozer oil water gas three-phase combined cooler provided by the embodiment is actually used, three coolers (namely a water cooler, a gas cooler and an oil cooler) should be manufactured by adopting the same structure, and the three coolers have the same structure and are respectively provided with the first seal head 1 and the heat exchanger core 2, so that the heat exchange efficiency of any wetland bulldozer oil water gas three-phase combined cooler is ensured to be basically equivalent to that of a traditional wetland bulldozer oil water gas three-phase combined cooler.

In order to reduce as much as possible the resistance loss of the first fluid flowing through the vicinity of the first fluid inlet end due to the baffle arrangement, the wet land bulldozer oil water gas three-phase combination cooler 01 provided in embodiment 1 preferably has an opening shape of the orifice 102 that completely conforms to the shape of the first fluid inlet 201, as shown in fig. 3, 4, 5 and 7. According to the principle of fluid mechanics, when a flow channel is suddenly enlarged or reduced, eddy current loss is likely to occur, and a large resistance loss is generated, specifically, the loss is expressed by the reduction of the flow velocity of the fluid and the strong impact on the wall surface of the flow channel. The shape of the opening of the duct 102 is completely consistent with the shape of the first fluid inlet 201, so that the shape of the flow channel of the first fluid flowing through the first fluid inlet 20 is ensured to be hardly changed, the resistance loss of the first fluid flowing through the first fluid inlet 20 is reduced, the reduction of the flow rate of the fluid and the reduction of the heat exchange efficiency caused by the reduction of the flow rate of the fluid are avoided, the strong impact on the wall surface of the flow channel is reduced, and the service life of the wetland bulldozer oil water-gas three-phase combination cooler 01 is further prolonged.

In order to adapt to the conventional marshland bulldozer oil-water-gas three-phase combination cooler, the opening of the hole 102 in the marshland bulldozer oil-water-gas three-phase combination cooler 01 provided in example 1 is in a long strip shape, as shown in fig. 3, 4, 5 and 7. Since the fluid passage of the conventional wet land bulldozer oil-water-gas three-phase combined cooler is generally in the shape of a plate-shaped cuboid with a small thickness, the first fluid inlet 201 is in the shape of a long strip. Therefore, in order to adapt to the traditional wetland bulldozer oil water-gas three-phase combination cooler, the opening of the duct 102 is in a long strip shape, which ensures that the shape of the flow channel of the first fluid flowing through the vicinity of the first fluid inlet end 20 is hardly changed, thereby reducing the resistance loss of the first fluid flowing through the vicinity of the first fluid inlet end 20, avoiding the reduction of the fluid flow rate and the reduction of the heat exchange efficiency caused by the reduction of the strong impact on the wall surface of the flow channel, and being beneficial to further prolonging the service life of the wetland bulldozer oil water-gas three-phase combination cooler 01.

The multipoint (at least two points) convex part 1010 and the concave part 202 are clamped and fixed, so that the baffle 10 and the first fluid inlet end 20 can be positioned and assembled quickly, the mounting speed of the baffle 10 is greatly improved, and the mounting precision is ensured; while also facilitating an improved snug fit between the face of baffle 10 and first fluid inlet end 20.

In order to enhance the pressure resistance of the first seal head, in the wetland bulldozer oil water gas three-phase combination cooler 01 provided in embodiment 1, preferably, as shown in fig. 2 to 4, the first seal head 1 is a floating seal head. The floating seal head can automatically extend and retract along the axial direction of the seal head in a free length manner under the change of factors such as pressure, temperature and the like, so that the volume of the first seal head 1 is enlarged or reduced within a certain range, and the effect of increasing the pressure resistance is achieved; when the temperature change is large, the axial, transverse and angular thermal stress of the first seal head 1 can be compensated and absorbed; the floating seal head can also absorb the vibration of the equipment, and the influence of the vibration of the equipment on each part is reduced.
