Description

Technical Field

[0001] This utility model relates to the field of water-air cooler technology, specifically a high-sealing water-air cooler. Background Technology

[0002] In fields such as automotive engines, construction machinery power systems, and marine propulsion systems, intercoolers are key devices for reducing the temperature of boosted air and increasing intake air density, directly affecting the combustion efficiency, power output, and emission performance of power units. Among them, water-intercoolers, which use water as the cooling medium, have the advantages of high cooling efficiency and strong adaptability to complex operating conditions, and have been widely used in high-power-density power systems.

[0003] Currently, when water-air coolers are connected and used, the connection between the inlet and outlet of the water cooler mostly adopts a single sealing ring structure. When the pressure of the water supply pipe and the inlet and outlet is uneven during assembly, it is easy to cause insufficient compression of the sealing ring or excessive compression in some areas, forming a sealing gap, which in turn causes coolant leakage, thus greatly reducing the sealing performance of the water-air cooler connection. Therefore, a water-air cooler with high sealing performance is needed. Utility Model Content

[0004] The purpose of this invention is to provide a highly airtight water-air cooler to solve the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution:

[0005] This utility model relates to a high-sealing water-air cooler, comprising:

[0006] The intercooler housing has an inlet pipe and an outlet pipe respectively connected to both sides of the top of the intercooler housing;

[0007] A sealing component includes a sealing frame and two first sealing rings. The inner walls of the two first sealing rings are respectively fixedly disposed on both sides of the outer wall of the liquid inlet pipe. The sealing frame is fixedly disposed on the outer wall of the liquid inlet pipe below the first sealing rings. A second sealing ring is fixedly disposed on both sides of the inner wall of the sealing frame. A reinforcing sealing gasket is fixedly disposed at the bottom end of the inner wall of the sealing frame, and the size of the reinforcing sealing gasket is adapted to the size of the bottom end of the sealing frame.

Detailed Implementation

[0023] 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown, this utility model is a high-sealing water-air cooler, comprising:

[0026] Intercooler housing 11, with liquid inlet pipe 12 and liquid outlet pipe 13 respectively connected to the two sides of the top of the intercooler housing 11.

[0027] The intercooler housing 11 has a heat exchange core inside, with an intake pipe and an exhaust pipe at each end. The heat exchange core is connected to the intake pipe and the exhaust pipe respectively. When high-temperature pressurized air enters the heat exchange core through the intake pipe, it exchanges heat with the cooling water in the water-side channel outside the heat exchange core and is discharged from the exhaust pipe, thereby achieving a rapid reduction in the temperature of the pressurized air. The liquid inlet pipe 12 and the liquid outlet pipe 13 are connected to the cooling water supply pipe respectively.

[0028] The sealing component includes a sealing frame 22 and two first sealing rings 21. The inner walls of the two first sealing rings 21 are respectively fixedly disposed on both sides of the outer wall of the liquid inlet pipe 12. The sealing frame 22 is fixedly disposed on the outer wall of the liquid inlet pipe 12 below the first sealing rings 21. The inner walls of the sealing frame 22 are fixedly disposed on both sides of the second sealing ring 23. The bottom end of the inner wall of the sealing frame 22 is fixedly disposed with a reinforcing sealing gasket 24, and the size of the reinforcing sealing gasket 24 is adapted to the size of the bottom end of the inner wall of the sealing frame 22.

[0029] Both the inlet pipe 12 and the outlet pipe 13 are equipped with sealing components on their outer walls. The first sealing ring 21, the second sealing ring 23, and the reinforcing sealing gasket 24 are all made of rubber.

[0030] The two first sealing rings 21 and the two second sealing rings 23 are arranged alternately.

[0031] The sealing component also includes two fixing seats 25, with the opposite sides of the two fixing seats 25 respectively fixedly disposed on both sides of the outer wall of the sealing frame 22;

[0032] Working principle: When connecting the water-air cooler, insert the end of the coolant delivery pipe between the inlet pipe 12 and the sealing frame 22 until the end of the delivery pipe is tightly fitted with the reinforcing sealing gasket 24 at the bottom of the inner end of the sealing frame 22. At this time, the inner wall of the delivery pipe is connected and sealed with the outer wall of the inlet pipe 12 under the action of the first sealing ring 21, and the outer wall of the delivery pipe is connected and sealed with the inner wall of the sealing frame 22 under the action of the second sealing ring 23. Similarly, the delivery pipe and the outlet pipe 13 are connected. Under the combined action of the first sealing ring 21, the second sealing ring 23 and the reinforcing sealing gasket 24, the delivery pipe can be connected and sealed in all directions, avoiding coolant leakage caused by uneven clamping force between the delivery pipe and the inlet and outlet during assembly, thereby greatly improving the sealing performance of the water-air cooler connection.

[0033] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0034] The fixing component includes four elastic metal pieces 31. The outer walls of the four elastic metal pieces 31 are provided with external threads 32. The outer walls of the four elastic metal pieces 31 are slidably provided with a locking cover 33 below the external threads 32. The bottom end of the locking cover 33 is rotatably provided with a connecting cover 34. The two sides of the bottom end of the connecting cover 34 are fixed with vertical rods 35. The outer walls of the two vertical rods 35 pass through the top ends of the two fixing seats 25 respectively.

[0035] The inner wall of the locking cover 33 is provided with a threaded groove that matches the external thread 32. The four elastic metal pieces 31 can be easily gathered and fixed by the locking cover 33, and the vertical rod 35 slides with the fixed seat 25.

[0036] The fixing component also includes four first limiting blocks 37, with the opposite sides of the four first limiting blocks 37 respectively fixedly disposed at the top of the outer wall of the four elastic metal sheets 31, and a locking screw 371 passing through one side of the first limiting block 37.

[0037] The first limiting block 37 is used to limit the movement of the locking cover 33 to prevent it from moving off the elastic metal sheet 31. The locking screw 371 is threadedly engaged with the first limiting block 37. The locking screw 371 is used for auxiliary connection and fixation, thereby improving the firmness of the connection between the inlet / outlet pipe and the water supply pipe.

[0038] The fixing component also includes an annular slide bar 38, the top end of which is fixedly disposed at the bottom end of the locking cover 33, and the outer wall of the annular slide bar 38 is slidably connected to the top end of the connecting cover 34.

[0039] The annular slide bar 38 has a T-shaped cross section and is used for the rotatable connection between the locking cover 33 and the connecting cover 34. The top of the connecting cover 34 is provided with an annular groove that is adapted to the annular slide bar 38.

[0040] The bottom ends of both vertical rods 35 are fixed with second limiting blocks 36;

[0041] The second limiting block 36 is used to assist in limiting the movement of the vertical rod 35.

[0042] Working principle: After the water supply pipe is connected and sealed with the inlet and outlet pipes, the locking cover 33 is moved upward until it contacts the external thread 32. Then, the locking cover 33 is rotated, and it moves upward under the action of the external thread. At the same time, it drives the four elastic metal pieces 31 to retract inward, so that the inner side of the elastic metal pieces 31 is tightly fitted with the outer wall of the water supply pipe until the locking cover 33 contacts the bottom end of the first limit block 37. Then, the locking screws 371 are rotated until one end of the locking screws 371 contacts the outer wall of the water supply pipe. This method facilitates the connection and fixation of the water supply pipe, thereby improving the firmness of the connection between the water supply pipe and the inlet and outlet pipes.
