In order to solve the above problem, an evaporator is provided in the present embodiment, which has a high assembly and disassembly efficiency and a good user experience.

In particular, referring to fig. 1-6, in the present embodiment, the evaporator comprises a water tray 1, two header plates 2 and two evaporator assemblies 3.

Both sides of the water pan 1 are provided with limiting structures 11.

The two end plates 2 are respectively arranged at two ends of the water pan 1.

Two evaporator assembly 3 are the contained angle setting, and two evaporator assembly 3 set up respectively in the both sides of water collector 1, and the both ends of each evaporator assembly 3 are connected with two end board 2 respectively, and two evaporator assembly 3 correspond the setting respectively with the limit structure 11 of the both sides of water collector 1, and evaporator assembly 3 pegs graft or the butt with the limit structure 11 that this evaporator assembly 3 corresponds.

Further, in this embodiment, the ends of the two evaporator assemblies 3 away from the water pan 1 are away from each other, that is, in this embodiment, the evaporators are V-shaped evaporators.

The oppositely disposed surfaces of the two evaporator elements 3 are the inner surfaces of the evaporators, and the outer surfaces of the evaporator elements 3, i.e. the surfaces of the evaporator elements 3 facing away from the other evaporator element 3. Specifically, in the present embodiment, the end plate 2 has an inverted trapezoidal shape. The end plate 2 is arranged perpendicular to the extending direction of the water pan 1.

Specifically, in the present embodiment, the evaporator unit 3 abuts against the limit structure 11 corresponding to the evaporator unit 3. Preferably, the outer surface of the evaporator assembly 3 abuts against the limiting structure 11 corresponding to the evaporator assembly 3, so that the limiting structure 11 can provide an obliquely upward supporting force to the evaporator assembly 3.

Of course, in other embodiments, the evaporator assembly 3 is inserted into the corresponding limiting structure 11 of the evaporator assembly 3; be provided with on evaporator assembly 3's the surface towards water collector 1 with limit structure 11 complex inserting groove, limit structure 11 is protruding the spacing arch of locating the surface of water collector 1, and the inserting groove is pegged graft with spacing protruding cooperation, realizes locating evaporator assembly 3's quick installation.

Set up limit structure 11, limit structure 11 and the cooperation of end board 2, the two is spacing on water collector 1 to evaporator assembly 3 jointly, need not to adopt a large amount of screws to realize the installation of evaporator assembly 3 on water collector 1 for evaporator assembly 3 is quick in the dismouting on water collector 1, improves dismouting efficiency, reduces the assembly and disassembly cost, guarantees user experience.

In the prior art, the end of the evaporator assembly is also mounted on the end plate through a large number of screws, so that the evaporator assembly is low in assembly and disassembly efficiency and poor in user experience. In the prior art, because the installation position of the evaporator assembly is inclined relative to the water receiving tray, when the evaporator assembly is installed on the end plate, at least one operator needs to hold the evaporator assembly by hand to enable the evaporator assembly to be inclined to the water receiving tray, and the other operator performs screwing operation; i.e., screws, are used to mount the evaporator assembly to the header plate, requiring at least two operators results in a high labor cost for assembly.

In order to solve the above problem, in this embodiment, two ends of the evaporator assembly 3 are respectively connected to the two end plates 2 in a clamping manner. The installation of the evaporator assembly 3 on the end plate 2 is realized by adopting the clamping mode, only one operator needs to hold the evaporator assembly 3 and clamp the evaporator assembly 3 on the end plate 2, and the other operator is not required to screw, so that the number of required people for dismounting is reduced, and the tool is not required to be used during dismounting, thereby avoiding the interference of the tool on the assembly of the evaporator and reducing the assembly cost.

Further, in order to realize the clamping connection between the evaporator assembly 3 and the end plate 2, in the embodiment, the evaporator further comprises a clamping connection assembly.

Both ends of the evaporator component 3 are respectively clamped with the two end plates 2 through clamping components. The clamping assembly comprises clamping holes 211 and clamping lugs 31 which are arranged in a one-to-one correspondence mode, one of the clamping holes 211 and the clamping lugs 31 of the clamping assembly is arranged on the end plate 2, and the other clamping hole is arranged on the evaporator assembly 3.

After the clamping lug 31 extends into the clamping hole 211, the evaporator assembly 3 can move to the limiting structure 11 corresponding to the evaporator assembly 3 along the direction far away from the water receiving tray 1, and the clamping lug 31 can also be separated from the clamping hole 211 at the moment.

The evaporimeter that this embodiment provided places water collector 1 on leveling the mount table earlier when the equipment, then installs two end board 2 respectively to the both ends of water collector 1. Then, an operator stands on one side of the water receiving tray 1, holds one evaporator assembly 3 by hand, and extends the clamping lug 31 into the clamping hole 211, then the operator approximately puts the evaporator assembly 3 down along the inclination direction of the evaporator assembly 3, and the evaporator assembly 3 moves along the direction close to the water receiving tray 1 until the limiting structure 11 corresponding to the evaporator assembly 3 is abutted and the clamping lug 31 is clamped in the clamping hole 211.
