[0028] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the technical solutions of the present disclosure will be clearly and completely described below in combination with the specific embodiments of the present disclosure and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0029] Combination Figures 1 to 5 As shown, an embodiment of the present disclosure provides a surface cooler, comprising: at least two cooling units 1; each of the at least two cooling units 1 is provided with a medium inlet pipe 2 and a medium outlet pipe 3, and the medium inlet pipe 2 and the medium outlet pipe 3 are both provided with a quick-connect joint 4; the medium inlet pipes 2 of at least two cooling units 1 are respectively connected through the quick-connect joints 4, and the medium outlet pipes 3 of at least two cooling units 1 are respectively connected through the quick-connect joints 4.

[0030] The surface cooler disclosed in this embodiment adopts a modular structure. According to different cooling capacity requirements, different numbers of cooling units 1 are selected for rapid assembly through quick-connect joints 4. The cooling units 1 have the same structure and are simple in structure, which is convenient for batch and automated production, and can significantly improve the production efficiency of the cooler production plant. According to the requirements for different cooling capacities, several cooling units 1 can be flexibly combined according to the space, which can meet the cooling capacity and adjust the combination method according to the space, which is convenient to use.

[0031] The purpose of the present disclosure and the solution of its technical problems can also be further achieved by adopting the following technical measures.

[0032] In some embodiments, the quick connector 4 includes a connector body 5, a medium cavity 6 is provided in the connector body 5, and the medium cavity 6 is provided with a first interface 7, a second interface 8, and a third interface 9. The shapes of the first interface 7 and the third interface 9 match each other, so that any two quick connectors 4 can be quickly connected and quickly replaced by the cooperation of the first interface 7 and the third interface 9, and the second interface 8 is connected to the medium inlet pipe 2 or the medium outlet pipe 3. The quick connector 4 of this embodiment has the advantages of simple structure, convenient and fast connection operation, and does not affect the medium inlet and outlet of the cooling unit.

[0033] In this embodiment, the quick connector 4 is made of steel material, and any two quick connectors 4 can be sealed and fixed by welding after being plugged in and matched.

[0034] In some embodiments, the inner peripheral wall of the first interface 7 is a tapered surface 10, and the outer peripheral wall of the third interface 9 is a tapered surface 10. When any two cooling units 1 are connected, the first interface 7 of the joint body 5 of one cooling unit 1 is plugged with the third interface 9 of the joint body 5 of another cooling unit 1, or the third interface 9 of the joint body 5 of one cooling unit 1 is plugged with the first interface 7 of the joint body 5 of another cooling unit 1. The quick connector 4 adopts a double tapered surface structure to facilitate the combined plug-in of multiple cooling units 1.

[0035] In some embodiments, the first interface 7 is arranged upstream in the medium flow direction, the third interface 9 is arranged downstream in the medium flow direction, and the second interface 8 is arranged between the first interface 7 and the third interface 9. When any two cooling units 1 are connected, the third interface 9 of the joint body 5 of the cooling unit 1 close to the upstream of the medium flow direction is plugged into and matched with the first interface 7 of the joint body 5 of the cooling unit 1 close to the downstream of the medium flow direction. Therefore, when the cooling units 1 are assembled, the insertion direction of the quick connector 4 is the same as the medium flow direction, and leakage is not easy to occur.

[0036] In some embodiments, each of at least two cooling units 1 is provided with a heat exchange tube 11, and the heat exchange tube 11 is connected between the medium inlet tube 2 and the medium outlet tube 3. The medium flows in through the medium inlet tube 2, flows along the heat exchange tube 11 for heat exchange, and then flows out through the medium outlet tube 3. The medium inlet tube 2 is arranged at the lower part, and the medium outlet tube 3 is arranged at the upper part. After the medium flows in, it flows along the heat exchange tube 11, and heat is exchanged with the external air during the process.

[0037] In some embodiments, the length of the medium inlet pipe 2 is not equal to the length of the medium outlet pipe 3, which is used to distinguish the medium inlet and outlet. At the same time, this staggered structure facilitates the subsequent connection of external pipelines.

[0038] In some embodiments, there are at least two heat exchange tubes 11, at least two heat exchange tubes 11 are arranged in parallel, and at least two heat exchange tubes 11 are connected through a bend tube 15, forming at least one heat exchange channel for unidirectional flow of medium in the cooling unit 1.

[0039] In some embodiments, each of the at least two cooling units 1 is provided with a fin group 12, and the fin group 12 is installed on the heat exchange tube 11. The fin group 12 can increase the heat exchange area of ​​the heat exchange tube 11 and improve the heat exchange efficiency.

[0040] In some embodiments, each of the at least two cooling units 1 is provided with a frame structure 13, and the frame structure 13 is configured to fix the heat exchange tube 11. The frame structure 13 is a quadrilateral frame composed of four upper, lower, left and right frames, which facilitates the fixation of the heat exchange tube 11 and the fin group 12.

[0041] In some embodiments, the frame structure 13 is further provided with a connection structure 14 , which is constructed as a hole opened on the frame structure 13 for interconnecting adjacent cooling units 1 on the left and right and on the top and bottom.

[0042] The surface cooler of this embodiment has a modular structure, and any number can be selected for rapid assembly according to different cooling capacity requirements. The connection operation is convenient and fast, and the performance is reliable. The cooling unit has a simple structure, which is convenient for mass production and helps to reduce production costs. The cooling unit can be assembled in various ways, and can be assembled in all directions up, down, left, and right, which can meet different space requirements.

[0043] An air conditioner adopts the above-mentioned surface cooler.

[0044] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0045] The above are only preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure. The above are only preferred implementations of the present disclosure. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present disclosure, and these improvements and variations should also be regarded as the protection scope of the present disclosure.
