The top cover sleeved on the collecting pipe is not easy to be damaged by the water pressure in the collecting pipe.

[0004] In the process of introducing cold water or hot water into the water inlet collecting pipe, and then the water in the water inlet collecting pipe into the heat exchange pipe, after the water enters the water inlet collecting pipe, it falls to the bottom of the water inlet collecting pipe, and then flows into the heat exchange pipe at the bottom of the water inlet collecting pipe, that is, the water in the water inlet collecting pipe cannot flow into several heat exchange pipes at the same time, and the heat exchange pipe without water entering does not have the function of heat exchange, so that the heat exchange efficiency is low, and improvement is needed. Practical new type content

[0005] In order to improve the problem that several heat exchange pipes cannot be filled with water at the same time, resulting in low heat exchange efficiency, the present application provides a stainless steel surface air cooler for air conditioning system.

When air flows through the surface cooler, the cooling water in the surface cooler absorbs the heat in the air through heat conduction and convection and carries it outside the surface cooler, thereby achieving the purpose of cooling.

[0009] When the plurality of heat exchange pipes are simultaneously watered, the cooling water can be uniformly distributed in each heat exchange pipe, ensuring that each heat exchange pipe can fully contact the cooling water, i.e. each heat exchange pipe has cooling function, thereby improving the efficiency of heat exchange.

[0015] By adopting the technical scheme, when the baffle is moved to be separated from the end of the heat exchange pipe and the filter plate completely covers the end of the heat exchange pipe, the pull rod is just moved to the limiting hole, at this time, the limiting block is turned over and inserted into the limiting hole, the inner wall of the limiting hole abuts against the side wall of the limiting block, and the limiting effect is achieved, so that the pull rod cannot continue to move, and the baffle cannot move, the state that the end of the heat exchange pipe is in communication with the water inlet pipe is maintained, and the continuous circulation of the cooling water is facilitated.

[0016] Optionally, a magnetic block is fixed on the inner wall of the limiting hole, and the magnetic block can be attracted to the limiting block.

[0020] Optionally, a magnetic strip is embedded on the rubber pad, and the magnetic strip is attracted to the inner wall of the water inlet pipe.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings Figures 1-4 The application is further described in detail.

[0033] The embodiment of the application discloses a kind of stainless steel surface condenser for air conditioning system. Refer to Figure 1 and Figure 2The stainless steel surface cooler for air conditioning systems comprises a surface cooler body 10, a water inlet pipe 20 and a water outlet pipe 30. A plurality of heat exchange pipes 11 are arranged in the surface cooler body 10. One end of the heat exchange pipes 11 is communicated with the water inlet pipe 20, and the other end is communicated with the water outlet pipe 30. The water inlet pipe 20 and the water outlet pipe 30 are arranged along the vertical direction, and the water inlet pipe 20 penetrates the upper and lower portions. The end portion of the water inlet pipe 20 is threadedly sleeved with a mounting cap for disassembly, thereby facilitating the cleaning of the inner wall of the water inlet pipe 20. The mounting cap is made of flexible rubber material, which can be deformed to prevent the water pressure in the water inlet pipe 20 from damaging the mounting cap.

[0034] With reference to Figure 1 and Figure 2 The end portions of the plurality of heat exchange pipes 11 are arranged at intervals along the length direction of the water inlet pipe 20. A baffle plate 40 is arranged in the water inlet pipe 20 along the length direction of the water inlet pipe 20. The baffle plate 40 can completely block the end portions of all the heat exchange pipes 11, so that the heat exchange pipes 11 are not communicated with the water inlet pipe 20. A filter plate 50 is fixed on the side wall of the baffle plate 40. The filter plate 50 is as long as the baffle plate 40, and extends along the circumference of the heat exchange pipes 11.

[0035] With reference to Figure 3 and Figure 4 A pull rod 41 is fixed on the side wall of the baffle plate 40. A moving groove 21 is formed on the side wall of the water inlet pipe 20 along the circumference of the water inlet pipe 20. The pull rod 41 penetrates the moving groove 21 and can move in the moving groove 21. In use, the baffle plate 40 first completely blocks the end portions of the heat exchange pipes 11, so that the plurality of heat exchange pipes 11 are not communicated with the water inlet pipe 20. Then, cooling water is introduced into the water inlet pipe 20 until the cooling water fills the water inlet pipe 20. The pull rod 41 is pulled to move the baffle plate 40 along the circumference of the water inlet pipe 20, so that the baffle plate 40 moves out of the end portions of the heat exchange pipes 11. At the same time, the filter plate 50 moves to the end portions of the heat exchange pipes 11, thereby shielding the end portions of the heat exchange pipes 11. The cooling water in the water inlet pipe 20 can only pass through the filter plate 50 to enter the heat exchange pipes 11. The filter plate 50 plays a filtering role, so that impurities in the cooling water are less likely to flow into the heat exchange pipes 11, reducing the blockage of the heat exchange pipes 11 due to impurity accumulation, thereby affecting the flow of the cooling pipe and reducing the influence on the heat exchange efficiency.

[0036] In this process, when the cooling water fills the water inlet pipe 20, i.e., the cooling water in the water inlet pipe 20 overflows the end portions of all the heat exchange pipes 11, the simultaneous water inlet of the plurality of heat exchange pipes 11 is realized, so that the cooling water can be uniformly distributed in each heat exchange pipe 11, ensuring that each heat exchange pipe 11 can fully contact the cooling water, i.e., each heat exchange pipe 11 has cooling function, thereby improving the heat exchange efficiency.

[0037] With reference to Figure 3 and Figure 4The limiting block 42 is hinged to the end of the pull rod 41 extending into the water inlet pipe 20. A limiting hole 22 is formed on the outer wall of the water inlet pipe 20, and a magnetic block 23 is fixed on the inner wall of the limiting hole 22. When the baffle 40 is moved to be separated from the end of the heat exchange pipe 11 and the filter plate 50 completely covers the end of the heat exchange pipe 11, the pull rod 41 is just moved to the limiting hole 22. At this time, the limiting block 42 is turned over and inserted into the limiting hole 22. The inner wall of the limiting hole 22 abuts against the side wall of the limiting block 42 to limit the movement of the pull rod 41, so that the baffle 40 cannot be moved, and the end of the heat exchange pipe 11 is kept in communication with the water inlet pipe 20 to facilitate the continuous flow of cooling water.

[0038] With reference to Figure 3 In order to prevent the baffle 40 and the filter plate 50 from abrading the water inlet pipe 20 when they are moved, rubber pads 60 are fixed on the sides of the baffle 40 and the filter plate 50 close to the inner wall of the water inlet pipe 20, and the rubber pads 60 abut against the inner wall of the water inlet pipe 20. A magnetic strip 61 is embedded in the rubber pad 60 and is attracted to the inner wall of the water inlet pipe 20.

[0039] The magnetic strip 61 is attracted to the inner wall of the water inlet pipe 20, so that the rubber pad 60 abuts against the inner wall of the water inlet pipe 20 more tightly, improving the sealing performance and preventing the cooling water in the water inlet pipe 20 from reaching between the baffle 40 and the inner wall of the water inlet pipe 20, i.e. preventing the cooling water from flowing out of the moving groove 21. When the baffle 40 is moved, the rubber pad 60 slides on the inner wall of the water inlet pipe 20, and the rubber pad 60 plays a protective role, so that the baffle 40 and the filter plate 50 are less likely to abrade the water inlet pipe 20, prolonging the service life.

[0040] With reference to Figure 2 A guide block 70 is further fixed on the baffle 40 and the filter plate 50, and a guide groove is formed on the inner wall of the water inlet pipe 20 along the circumferential direction of the water inlet pipe 20. The guide block 70 is inserted into the guide groove and can move in the guide groove.

[0041] When the baffle 40 is driven to move, the guide block 70 moves in the guide groove, and the inner wall of the guide groove abuts against the side wall of the guide block 70 to limit the movement of the guide block 70, so that the baffle 40 only moves along the circumferential direction of the water inlet pipe 20, increasing the stability of the movement of the baffle 40.

[0042] Finally, when the baffle 40 and the filter plate 50 need to be cleaned or maintained, the mounting cap is unscrewed from the water inlet pipe 20. Then the baffle 40 and the filter plate 50 are moved to the center of the water inlet pipe 20, and the baffle 40 and the filter plate 50 are detached from the water inlet pipe 20 and completely separated from the water inlet pipe 20 through the end opening of the water inlet pipe 20, so that the baffle 40 and the filter plate 50 can be cleaned and maintained.

[0043] The implementation principle of the stainless steel surface condenser for the air conditioning system in the embodiment of the present application is as follows: during use, the baffle 40 first completely blocks the end of the heat exchange pipe 11, so that the heat exchange pipes 11 are not communicated with the water inlet pipe 20, then cooling water is introduced into the water inlet pipe 20, and after the cooling water fills the water inlet pipe 20, the baffle 40 is moved to separate the baffle 40 from the end of the heat exchange pipe 11, so that the end of the heat exchange pipe 11 is not blocked and is communicated with the water inlet pipe 20, at this time, the cooling water in the water inlet pipe 20 overflows the end of all the heat exchange pipes 11, so that the water inlet of the heat exchange pipes 11 is simultaneously realized, so that the cooling water can be uniformly distributed in each heat exchange pipe 11, and it is ensured that each heat exchange pipe 11 can fully contact the cooling water, that is, each heat exchange pipe 11 has a cooling function, so that the heat exchange efficiency is improved.

[0044] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
