In the prior art, each section of the multifold evaporator is a complete assembly, each assembly comprises an edge plate on two sides and a plurality of fins, and the fins and the edge plates in each assembly are independent from each other. When the evaporator is produced, fins and side plates of different components are assembled together through an assembling process to form a preset bending angle, the production process is complex, the included angle between each fin and each side plate is influenced by personal factors of operators, assembling errors easily occur, and the product consistency is poor. In addition, gaps are formed in the splicing parts of the fins of different assemblies, the gaps need to be sealed, and the operation process is complex.

Disclosure of Invention

The invention solves the technical problems that the existing evaporator needs to be assembled when the side plate is installed, so that the production process is complex, the working time is long, the number of parts is large, and the parts are easy to lose.

In order to solve the problems, the invention provides an evaporator assembly, which comprises fins and side plates, wherein the shape of the fins is adapted to the shape of the side plates,

the side plate is of an integrated structure and is formed by bending an integrated side plate, wherein the side plate comprises a first edge which is a long side edge,

the side plate comprises at least one bending angle, the first edge is provided with at least one notch, and the bending angle is formed by bending the side plate along the notch.

Because sideboard formula structure as an organic whole is provided with the incision on the first edge of sideboard panel, need not to assemble during the installation sideboard, only need with sideboard panel along the incision buckle can, simplify production technology, shorten man-hour to make the part quantity of whole evaporimeter reduce, avoid the part to lose.

Further, the sideboard board still includes the second limit, the second limit be with the long side that first limit corresponds each other, the second edge is provided with at least one curved mouth, curved mouth with incision quantity equals, position one-to-one, curved mouth is used for making sideboard board follows when the incision is buckled, with the incision is corresponding the second border of curved mouth both sides curved mouth looks separation each other, mutual correspondence the incision with be provided with the connecting bridge between the curved mouth.

Because the second edge of sideboard panel is provided with corresponding crooked mouth, when the installation sideboard with sideboard panel along incision, crooked mouthful buckle can, avoid the second limit to tear.

Furthermore, the included angle formed by each notch is larger than or equal to the preset bending angle of the corresponding side plate formed by bending the side plate along the notch.

Because the contained angle that each incision formed is greater than or equal to the angle of buckling of the sideboard that this incision is buckled back and is formed of the sideboard panel of predetermineeing, buckle the sideboard panel in the incision position during installation sideboard and target in place and buckle into predetermined angle of buckling promptly, the contained angle of sideboard does not receive the influence of operating personnel personal factor, and the product uniformity is better, and installation error is little.

Further, each of the incisions is a V-shaped incision.

Because the incision is the V type incision, make the angle of bending of sideboard more controllable, further guarantee the angle of bending accuracy of sideboard to in the process of buckling, along first incision, the second notched minimum buckle can, the installation is easier.

Because be provided with the U pipe protection casing on the left side mounting panel 72, can avoid the exposed impaired of U pipe, prevent simultaneously that the U pipe from rocking for left side mounting panel 72.

Further, one or more U-tube shields 721 are provided with a blocking rib 723, and the blocking rib 723 is used for preventing the U-tubes from falling out of the left mounting plate 72.

Further, as shown in fig. 7 and 13, a right connecting plate 713 is disposed at an end of the right mounting plate 71 close to the top cover plate 08, that is, a right connecting plate 713 is disposed at an end of the right mounting plate 71 facing the positive direction of the coordinate axis Z axis, a left connecting plate 724 is disposed at an end of the left mounting plate 72 close to the top cover plate 08, that is, a left connecting plate 724 is disposed at an end of the left mounting plate 72 facing the positive direction of the coordinate axis Z axis, the right connecting plate 713 and the left connecting plate 724 are both parallel to the top cover plate 08, and the right connecting plate 713 and the left connecting plate 724 are both used for being connected to the top cover plate 08 through screws. Due to the arrangement of the left connecting plate and the right connecting plate, the evaporator assembly is more convenient to install.

Further, as shown in fig. 7 and 10, the evaporator assembly of the present invention further includes an electric heating device 09, the left and right ends of the electric heating device 09 are respectively provided with a limit pin 91, 92, the side plate 17, the left mounting plate 72, and the right mounting plate 71 are respectively provided with a limit pin hole, the limit pin 91 at the left end is inserted into the limit pin hole on the left mounting plate 72, and the limit pin 92 at the right end is sequentially inserted into the limit pin holes on the side plate 17 and the right mounting plate 71.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
