Evaporator assembling structure and top air-conditioner for vehicle applying same

Abstract

The invention relates to an evaporator assembling structure which comprises a volute casing, an evaporator and an evaporation draught fan, wherein the evaporation draught fan comprises an evaporation motor and an evapration fan or an evaporation wind wheel; the volute casing is provided with a first space and a second space; the bottom part of the first space is provided with an evaporation air inlet and a water receiving plate colse to the evaporation air inlet; the bottom part of the second space is provided with an evaporation air outlet; an evaporator is arranged on the water receiving plate and seperates the evaporation air inlet from the evaporation air outlet; and the evaporation fan or the evaporation wind wheel is positioned in the second space, and the second space forms an evaporation air duct. The invention also discloses a top air conditioner for the vehicle. Compared with the prior art, the invention has the advantages: the volute is manufactured by adopting an integral molding mode, has good closure property and heat exchange effect, additionally, the temperature conservation is uniform and favorable; the water receiving plate and the evaporation air duct are integrated, the simple and compact structure is ensured, the evaporator assembling structure is convenient and rapid to install, the requirement for mounting space is lowered, raw materials are reduced, andthe cost is controlled.

Description

technical field [0001] The invention relates to an assembly structure of an evaporator, which is suitable for an air conditioner, and also relates to an overhead air conditioner for a vehicle. Background technique [0002] The roof-mounted air conditioner for vehicles is a specially designed air conditioner, which is mainly used in field operation machinery, such as mobile vehicles, road toll stations and small boats. In order to ensure the comfort, health and operation safety of operators, outdoor operation machinery needs to be installed with air conditioning devices; mobile vehicles are recreational vehicles represented by RVs, which are generally used for home travel, leisure and living, etc., and car air conditioners are the basic components of RVs. One of the facilities must be available; in addition, in vehicles such as mobile blood collection vehicles, medical vehicles, and cabs of field construction machinery, personnel and equipment need to have adapted air conditi...

Problems solved by technology

[0004] At present, first of all, the bottom of the existing evaporator is often equipped with a special independent component water receiving tray, and the evaporator, evaporating fan and the air duct corresponding to the evaporating fan are located in the shell, occupying a large volume, requiring more materials and assembling. It is more cumbersome, and the manufacturing cost has been difficult to reduce; secondly, the existing anti-turbulence design of the structure is more complicated, and more materials are used, which affects the manufacturing cost; finally, the switching of the condensing fan and the evaporating fan in the existing design are both at the same time, which is the same Controlled, there is a phenomenon of wasting power and increasing noise
