[0057] Combination Figure 1-2 and Figure 6-7 As shown, the first tube sheet 10 is suitable for being arranged at the first side end of the first evaporator 30, and the first tube sheet 10 is provided with a first protrusion 11; the second tube sheet 20 is suitable for being arranged at the first side end of the second evaporator 40, and the second tube sheet 20 is provided with a first embedded portion 21, and the first embedded portion 21 is embedded with the first protrusion 11, so as to limit the relative position between the first tube sheet 10 and the second tube sheet 20.

[0058] The first tube sheet 10 is suitable for being arranged at a first side end of the first evaporator 30, and the second tube sheet 20 is suitable for being arranged at a first side end of the second evaporator 40. It can be understood that the first tube sheet 10 and the second tube sheet 20 are located on the same side of the evaporator.

[0059] By using the tube sheet assembly for the evaporator provided by the embodiment of the present disclosure, the first protrusion 11 cooperates with the first embedded portion 21 to limit the first tube sheet 10 and the second tube sheet 20 along the length direction of the evaporator, limit the axial displacement of the first tube sheet 10 and the second tube sheet 20, and prevent the adjacent first evaporator 30 and the second evaporator 40 from being offset and misaligned along the length direction of the evaporator. At the same time, since the first embedded portion 21 is inserted into the first protrusion 11 and fits with each other to form a snap-on structure, the contact area and interaction force between the first protrusion 11 and the first embedded portion 21 can be increased in a direction perpendicular to the length of the evaporator, thereby limiting the radial displacement of the first tube sheet 10 and the second tube sheet 20. The inserted limiting structure can also achieve angular limiting to a certain extent, preventing relative rotation between the first tube sheet 10 and the second tube sheet 20. Therefore, through the insertion-type interlocking limitation between the first embedded portion 21 and the first protruding portion 11, it is possible to limit the first tube sheet 10 and the second tube sheet 20 in multiple directions, thereby improving the fixing effect between the first tube sheet 10 and the second tube sheet 20, thereby improving the structural stability of the tube sheet assembly.

[0062] The first protrusion 11 is arranged at the edge of the first tube sheet 10, and the first embedded portion 21 is arranged at the edge of the second tube sheet 20, so that the first tube sheet 10 and the second tube sheet 20 are limitedly connected at the edge. The limited connection at the edge can make the connection more compact and reduce the occupied space.

[0063] It can be understood that the number of the first protrusions 11 and the first embedded parts 21 can be multiple, multiple first protrusions 11 are provided on the first tube sheet 10, multiple first embedded parts 21 are provided on the second tube sheet 20, and the multiple first protrusions 11 and the multiple first embedded parts 21 correspond one to one.

[0064] Optionally, combined Figure 1 and Figure 6-7 As shown, the first protrusion 11 protrudes in a direction away from the first evaporator 30 to form a first slot 12 for the first embedded portion 21 to be inserted into; the first embedded portion 21 includes a first claw 22 extending toward the first slot 12, and the size of the first slot 12 is adapted to the size of the first claw 22.

[0065] The first protrusion 11 protrudes in a direction away from the first evaporator 30, so that there is no interference between the first protrusion 11 and the first evaporator 30, thereby avoiding affecting the normal operation of the evaporator. The first protrusion 11 protrudes to form a first clamping groove 12, and the size of the first clamping groove 12 is adapted to the size of the first claw 22, so that the first protrusion 11 can more effectively limit the first embedded portion 21, thereby improving the limiting effect between the first tube sheet 10 and the second tube sheet 20.

[0071] Through the setting of the polygonal limiting space, the multiple side edges 221 of the first clamping claw 22 correspond to the multiple side walls 122 of the first clamping groove 12 one by one, and the multiple side edges 221 of the first clamping claw 22 can be against the multiple side walls 122 of the first clamping groove 12, so that the first clamping claw 22 and the first clamping groove 12 can be accurately aligned in multiple directions. The first clamping claw 22 and the first clamping groove 12 are mutually embedded, which improves the limiting effect between the first embedded part 21 and the first protruding part 11, and limits the relative movement between the first tube sheet 10 and the second tube sheet 20 in multiple directions, thereby improving the stability of the overall structure of the tube sheet assembly. At the same time, the setting of the polygonal structure of the first clamping claw 22 and the first clamping groove 12 can simultaneously realize the installation guide and limiting functions.

At the same time, the outer edge of the top wall 121 of the first clamping groove 12 facing the second tube sheet 20 can also limit the outer surface of the first clamping claw 22. The outer edge of the first clamping groove 12 is set as a polygonal structure to enhance the limiting effect of the first clamping claw 22, and also enhance the structural strength of the first clamping groove 12.

Among them, the first card slot 12 includes three side walls 122 that are connected in sequence and are all connected to the top wall 121. The three side walls 122 correspond to the three edges of the top wall 121 one by one and are connected to each other. The first claw 22 includes three side edges 221. When the first claw 22 is inserted into the first card slot 12, the three side edges 221 of the first claw 22 correspond to the three side walls 122 of the first card slot 12 and fit into each other one by one. The outer edge of the top wall 121 located at the opening of the first card slot 12 includes two sections of sub-edges, which are bent and connected, corresponding to the outer surface of the first claw 22, and forming a limit on the outer surface of the first claw 22.

[0077] It can be understood that the first clamping groove 12 and the first clamping claw 22 can also be other polygonal structures.

[0078] Optionally, the first tube sheet 10 is further provided with a second embedded portion 13, and the second tube sheet 20 is further provided with a second protruding portion 23 correspondingly; wherein the second embedded portion 13 is extended toward the second protruding portion 23 so that the second embedded portion 13 can be inserted into the second protruding portion 23, so as to limit the relative movement between the first tube sheet 10 and the second tube sheet 20.

[0079] The first tube sheet 10 is provided with a first protruding portion 11, and the second tube sheet 20 is provided with a first embedded portion 21, and the first embedded portion 21 of the second tube sheet 20 is inserted into the first protruding portion 11 of the first tube sheet 10 to form a limiting fit.

[0082] The second protrusion 23 protrudes away from the second evaporator 40, so that there is no interference between the second protrusion 23 and the second evaporator 40, thereby avoiding affecting the normal operation of the evaporator. The second protrusion 23 protrudes to form a second clamping groove 24, and the size of the second clamping groove 24 is adapted to the size of the second claw 14, so that the second protrusion 23 can more effectively limit the second embedded portion 13, thereby improving the limiting effect between the first tube sheet 10 and the second tube sheet 20.

[0083] Optionally, combined Figure 6-7 As shown, the second protruding portion 23 is disposed on the edge of the second tube sheet 20 , and the second embedded portion 13 is disposed on the edge of the first tube sheet 10 , so as to form a limiting fit between the first tube sheet 10 and the second tube sheet 20 .

[0084] The matching structure of the second protruding portion 23 and the second embedded portion 13 can adopt the same matching structure as the matching structure of the first protruding portion 11 and the second embedded portion 13, and different performance requirements can be achieved by adjusting the size, shape or tightness of the matching structure.

[0088] It can be understood that the first opening 111 of the first protruding portion 11 is opened along the first direction, and the second opening 231 of the second protruding portion 23 is opened along the second direction. Accordingly, the first embedded portion 21 extends toward the first opening 111 along the first direction, and the second embedded portion 13 extends toward the second opening 231 along the second direction.

[0089] There is a deviation angle between the first direction and the second direction, that is, the first direction and the second direction are neither the same nor parallel, so that the opening directions of the first opening 111 and the second opening 231 are different. Accordingly, the extension directions of the first embedded portion 21 and the second embedded portion 13 are different, so that the insertion directions of the first embedded portion 21 and the second embedded portion 13 are different.
