Lightweight and energy-saving windward type overhead passenger car air conditioner

Abstract

The light-weight and energy-saving windward-mounted passenger car air conditioner of the present invention adopts a bottom shell assembly made of 5052 and H32 aluminum alloy plates, which is composed of a connecting plate assembly, a right bottom plate assembly, a rear end plate assembly, a left bottom plate assembly, and a bottom plate connecting plate. , a condenser core assembly and a condensing fan are arranged at the front of the bottom shell assembly, an evaporator core assembly and a fresh air mechanism are arranged at the rear, and a liquid reservoir, an evaporating fan, a shut-off valve, a drying Devices, air conditioning pipelines, expansion valves, electric control boxes and wiring harnesses. The bottom shell assembly of the present invention has more concise structure, thin plate, light weight and high strength, can significantly reduce the amount of materials used, and reduce production costs; in addition, spot welding is mainly used, which can significantly reduce the welding amount of argon arc welding, effectively Improve the production efficiency of the passenger car air conditioner; easy to produce, assemble and maintain; the passenger car air conditioner of the present invention is installed on the roof of the passenger car to form an overhead air conditioner.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of automobile air conditioners, in particular to a light-weight, energy-saving and windward-mounted passenger car air conditioner, which is especially suitable for installation and use in buses with a height of 8 to 12 meters. Background technique [0002] At present, buses generally use one-piece or two-section roof-mounted air conditioners, and buses of different models often use corresponding and different roof-mounted air conditioners. Although such products have individuality, they are not convenient for large-scale production and the cost is relatively low. higher. In addition, the existing top-mounted air conditioner is relatively heavy, not only consumes a lot of energy, but is also difficult to manufacture. [0003] The existing one-piece overhead car air conditioner has two devices (condenser and evaporator) sharing a base: generally, the condenser part is set at the fron...

AI Technical Summary

Problems solved by technology

The shortcomings of the existing integrated overhead air conditioner are: (1) Argon arc welding has a large amount of welding, and welding will produce thermal deformation

⑵The base is bulky, the plate is thick, heavy, and low in strength. Because the reverse side of the base also needs to be welded, it needs to be turned over manually, which makes the processing more difficult

(3) There is no positioning structure between the end plate and the bottom plate and between the bottom plate and the bottom plate, and large parts are clamped by forceps, which makes assembly difficult

⑷Argon arc welding is labor-intensive and requires high skills for welders

⑸ high manufacturing costs, not conducive to mass production
