Description

Rear evaporator of household air conditioner

Technical Field

The utility model belongs to the technical field of heat exchangers, and particularly relates to a rear evaporator of a household air conditioner.

Background

The fins of the existing evaporator of the household air conditioner are large in spacing, so that the heat exchange efficiency is low, and the evaporator is inconvenient and quick to install.

Disclosure of Invention

The heat exchange efficiency of the evaporator is low and the evaporator is inconvenient to install quickly due to the fact that the fins of the evaporator are large in distance after the existing household air conditioner is solved; the utility model aims to provide a household air conditioner rear evaporator which improves the heat exchange area and is convenient to install quickly.

The utility model relates to a rear evaporator of a household air conditioner, which comprises fins, long U tubes, short U tubes and end plates; the internally mounted of fin has a plurality of long U pipe, and the one end of the long U pipe of upside passes through short U union coupling with the one end of the long U pipe of downside, and the end plate is installed to the left end of fin, the spacing of fin is 1.3mm, thick 0.095mm of piece.

Preferably, the fins are aluminum foil.

Preferably, the pipe distance of the long U-shaped pipe is 21mm, and the row distance is 12.7mm.

Preferably, the end plate is integrally connected with a fixing plate.

Compared with the prior art, the utility model has the beneficial effects that:

1. the heat exchange area is large, and the heat exchange efficiency is improved.

2. Is convenient for quick fixation and firm fixation.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the present utility model is described below by means of specific embodiments shown in the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. The structures, proportions, sizes, etc. shown in the drawings are shown only in connection with the present disclosure, and are therefore not intended to limit the scope of the utility model, since any modification, variation in proportions, or adjustment of the size, which would otherwise be used by those skilled in the art, would not have the essential significance of the present disclosure, would still fall within the scope of the present disclosure without affecting the efficacy or achievement of the present disclosure. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

It should be noted here that, in order to avoid obscuring the present utility model due to unnecessary details, only structures and/or processing steps closely related to the solution according to the present utility model are shown in the drawings, while other details not greatly related to the present utility model are omitted.

As shown in fig. 1, 2 and 3, the following technical solutions are adopted in this embodiment: comprises fins 1, long U-tubes 2, short U-tubes 3 and end plates 4; the inside of fin 1 installs the long U pipe 2 of several, and the one end of the long U pipe 2 of upside and the one end of the long U pipe 2 of downside are passed through short U pipe 3 and are connected, and end plate 4 is installed to the left end of fin 1, fin 1's slice distance is 1.3mm, thick 0.095mm.

Further, in this embodiment, the fin 1 is an aluminum foil.

Further, in this embodiment, the long U-tube 2 has a tube pitch of 21mm and a row pitch of 12.7mm.

As shown in fig. 2, further, a fixing plate 41 is integrally connected to the end plate 4 in this embodiment.

The working principle of the specific embodiment is as follows: the product of the rear evaporator is molded and designed into a flat plate straight row, and the side faces are air-out, so that the product is difficult to connect during the process of punching and connecting the fins because of short length distance and single-row processing production, and the products are combined and produced together in multiple rows, and are cut and separated. The appearance structure size of the product is as follows: height 503mm, width 210mm, thickness: 12.7mm. The heat exchange amount of the machine set is required: 0.41kW, the heat exchange area of the unit is 1.20 square meters.

The flat plate processing of the evaporator core body, the welding flow path is operated according to the drawing arrangement pattern to finish welding, the upper end of the device body is provided with an installation connection end plate, the device body is sleeved on a shell of a client during assembly to finish assembly rapidly, one end of the long U is tightly sleeved on the plastic base of the client, and the device body is processed by using a gold hydrophilic aluminum foil shutter. The refrigerant fin type evaporator device has the advantages of strong universality, compact structure, simplicity in operation, safety and reliability, and adoption of a 1-in and 1-out flow design, so that the flow design of the refrigerant fin type heat exchanger is more convenient and reasonable.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

Furthermore, it should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is provided for clarity only, and that the disclosure is not limited to the embodiments described in detail below, and that the embodiments described in the examples may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
