Description

Technical Field

[0001] The utility model belongs to an automobile air conditioner, in particular to an automobile air conditioner HVAC assembly. Background Art

[0002] The blower of the existing automotive air conditioning device is usually integrated into the HVAC and arranged in the cab. The integrated design can reduce the size of the air conditioner to adapt to the narrow space of the car. At present, with the popularization of electric vehicles, the volume requirements of air conditioners are getting smaller and smaller. Today, with the increasingly rich functions of air conditioners, the smaller and smaller volume means that once the air conditioner fails, it is quite troublesome to repair. Due to the high failure rate of the fan at present, the cab dashboard and air conditioner assembly need to be disassembled and assembled during maintenance. In the actual maintenance process, the disassembly and assembly are complicated, and the maintenance is time-consuming and difficult. The current car air conditioning box is placed on the lower side of the dashboard in the car, which has the problem of loud noise from the air conditioner blower in the car, and occupies more layout space on the dashboard. Summary of the invention

[0003] The utility model aims to provide a blower external vehicle HVAC assembly, which makes the air conditioning structure efficient, reliable and comfortable by placing the blower externally, thereby meeting the requirements of modern vehicles.

[0004] To achieve the above purpose, the technical solution of the utility model is:

[0005] A blower-external vehicle HVAC assembly includes an air inlet module and an air outlet module, and is characterized in that: the air inlet module is arranged on the outside of a cab, and includes a front cover plate, an air inlet housing, and a blower volute; the front cover plate and the blower volute are connected to the air inlet housing via a detachable structure; the blower is fixed in the blower volute via screws; the filter element assembly is fixedly installed in the blower volute, directly below the blower, via screws; the air outlet module is arranged on the inside of the cab.

[0006] The detachable structure is a screw or a buckle.

[0007] The air outlet module includes a left shell, a right shell, and a lower shell, and the left and right shells are connected to the lower shell by screws; the evaporator assembly is vertically installed at the air inlet of the air outlet module after being clamped by the left and right shells; the warm air radiator is installed on the left and right shells in the air outlet module through a slot, and is located on the rear side of the evaporator assembly.

[0008] The utility model has the following beneficial effects: providing a blower external vehicle HVAC assembly, by arranging the blower outside the cab, the housings are connected by a detachable structure, which is convenient for disassembly and maintenance, and can also reduce the noise inside the car, save the layout space of the instrument panel inside the car, and make the structure of the air conditioning system in the cab more compact. In addition, a filter assembly is installed at the bottom of the blower, and the air supply in the internal and external circulation modes passes through the filter assembly, which improves the air quality in the cab. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 This is a schematic diagram of the explosion structure of the utility model;

[0010] Figure 2 It is a cross-sectional view of the utility model. DETAILED DESCRIPTION

[0011] The specific implementation of the present utility model is further described below in conjunction with the accompanying drawings.

[0012] See attached Figure 1 and 2 The air intake module is arranged outside the cab, and is composed of a front cover plate 1, an air intake housing 5, and a blower volute 3. The front cover plate 1, the air intake housing 5, and the blower volute 3 are connected by a detachable structure. The detachable structure is in the form of screws, buckles, etc. The blower 2 is installed in the blower volute 3 of the air intake module and fixed by screws. The air intake module is also equipped with a filter element assembly 4, which is fixed by screws below the blower volute 3 and directly below the blower 2.

[0013] The air outlet module includes a left shell 8, a right shell 9 and a lower shell 10, which are connected by buckles and bolts; the air outlet module is arranged on the inner side of the cab; the evaporator assembly 6 is clamped by the left and right shells and vertically installed at the air inlet of the air outlet module; the warm air radiator 7 is arranged in the air outlet module, clamped and fixed by the left and right shells, and is located on the rear side of the evaporator assembly 3.

[0014] When the blower 2 is repaired, it is only necessary to disassemble the front cover 1 and the blower volute 3 outside the cab and directly replace them; since the front cover 1, the air inlet housing 5, and the blower volute 3 are detachable structures, disassembly and assembly are very convenient. However, for many air conditioners HVAC in the current market, the maintenance of the blower requires the instrument panel to be disassembled from the cab, and then the HVAC housing is disassembled for replacement, which is very troublesome. The air inlet module is arranged outside the cab, and the filter element assembly 4 is installed at the bottom of the blower 2. The air supply in the internal and external circulation modes passes through the filter element assembly 4, which improves the air quality in the cab. The blower 2, the blower volute 3 and the filter element assembly 4 are integrated into a module and arranged outside the cab; the inner side air outlet module of the cab cancels the reserved blower installation position and is only composed of the evaporator assembly 6 and the warm air radiator 7, which reduces the volume of the air conditioner, saves the space for the instrument panel layout, and greatly increases the practicality.
