Abstract

The invention discloses an air conditioning evaporator assembly for an engineering vehicle, and relates to the technical field of the manufacturing of vehicle air conditioners. The air conditioning evaporator assembly comprises an evaporation fan, an evaporator core body and a heater core body. An evaporator casing is defined by an upper casing, a lower casing and a front cover plate, wherein an opening is formed in one side of each of the upper casing and the lower casing which are connected vertically, and the openings of the upper casing and the lower casing are in the same sides; a vertical partition board is arranged between the upper casing and the lower casing; the front cover plate is connected to the sides, in which the openings are formed, of the upper casing and the lower casing; the evaporation fan is arranged in the upper casing; air outlets of the evaporation fan are formed in the opening of the upper casing; and the evaporator core body and the heater core body are uprightly arranged in the lower casing side by side. The evaporator assembly disclosed by the invention can solve the problems of long maintenance time and low maintenance efficiency caused by the fact that a casing cannot be detached and mounted solely when an air conditioning evaporator for the engineering vehicle is repaired and the evaporator needs to be detached wholly for the maintenance of the internal parts of the evaporator.

Description

Construction engine A/C evaporator assembly
Technical field
The present invention relates to vehicle air conditioner manufacturing technology field, especially a kind of A/C evaporator assembly for construction engine air conditioner.
Background technology
Construction engine multiplex (MUX) does field in the open, and working environment is exceedingly odious.For the working environment of betterment works locomotive driving operating personal, the general supporting a/c system that has of construction engine, for regulating the temperature of driving in building.Being contained in the evaporator assembly of driving in building has refrigeration and two kinds of functions of heating, with engine cooling water, carries out heating, with R134a refrigerant, freezes.For guaranteeing that evaporator has good vibration resistance, evaporator shell is designed to integral type.Housing is comprised of three parts, and evaporator lower house is used for installing the various parts of evaporator, and evaporator side plate is arranged on evaporator lower house side for the protection of evaporator core, and evaporator upper cover is for the protection of evaporation fan.Three parts form a whole the parts such as evaporator core, evaporation fan are fixed, and protect the damage that parts are not subject to external force.Evaporator is arranged on driving upstairs, and side plate is relative with car body, with bolt, whole evaporator is fixed on car body, reconnects hot water pipe and air-conditioner pipe.Because construction engine is driven narrow space, evaporator installing space is limited, and evaporator side plate is close to car inwall, in the time of need to overhauling evaporator inner components, evaporator integral body can only be pulled down and could implement maintenance.During dismounting evaporator, also need to bleed off refrigerant and part cooling water expansion tank, cause waste, and step complex work amount is large, the repair time, large portion spent on dismounting, assembling evaporator, caused the repair time long, and maintenance efficiency is low.
Summary of the invention
The object of this invention is to provide a kind of construction engine A/C evaporator assembly, it can solve the dismounting separately of construction engine A/C evaporator when maintenance housing this construction engine A/C evaporator assembly, evaporator integral demounting must be got off, could overhaul evaporator inner components and cause the repair time long, the problem that maintenance efficiency is low.
In order to address the above problem, the technical solution used in the present invention is:
This construction engine A/C evaporator assembly, includes evaporation fan, evaporator core and heater cores, and evaporator shell is by upper shell, and lower house and front shroud surround; Described upper shell and described lower house all have a side to be provided with opening, described upper shell is connected up and down with described lower house, their the opening side that coexists, between described upper shell and described lower house, be provided with lower clapboard, described front shroud is connected to a side of described upper shell and described lower house opening; Described evaporation fan is arranged in described upper shell, and the air outlet of described evaporation fan is located on the opening of upper shell; Described evaporator core and described heater cores are erect side by side and are arranged in described lower house.
In above technical scheme, further scheme is: described evaporator core and described heater cores insert in lower house mounting groove, and described upper lower clapboard is pressed on two core bodys on lower house, by screw, upper lower clapboard is fixed on lower house; In the face of front shroud described in operator's compartment is screwed the side at described upper shell and described lower house opening.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, housing of the present invention by: lower house, upper shell, upper lower clapboard and front shroud four parts form, each several part easy accessibility, front shroud is in the face of not covering of operator's compartment, and be only screwed, be easy to disassemble, front shroud is removed the parts of finisher inside and all can be observed and touch, and is convenient to check that the failure condition of parts or dismounting need Awaiting Parts.
2, the present invention can change situation according to the maintenance of different parts, and optionally disengaging section housing is taken out needs to change parts, and needn't dismantle together by whole evaporator, as blower fan is changed, just only need the direct dismounting of blower fan is passable; As changed evaporator core or the heater cores of lower floor, only refrigerant or cooling water expansion tank need be bled off, just replaceable, and needn't dismantle together by whole evaporator, thereby save and detect maintenance time, maintenance efficiency improved.
