Top-mounted dual-air-returning air conditioner of passenger car

Abstract

The invention discloses a top-mounted dual-air-returning air conditioner of a passenger car. By adopting an overall-unit-type and dual-air-returning structural layout, the air conditioner and a car framework are fixedly installed below air conditioner bottom shells by installing transition beams; fresh air devices are arranged at the front ends of the air conditioner bottom shells, compressors andelectric control boxes are arranged at the rear ends of the air conditioner bottom shells, and condenser core body assemblies of left-right symmetric structures are arranged in the middles of the airconditioner bottom shells; by adopting the condenser core body assemblies, the condenser core body assemblies are connected with the left and right air conditioner bottom shells, the lower portions of the condenser core body assemblies are of non-bottom-shell structures, the condenser core body assemblies are flat placed below the air conditioner, and condensate fans are arranged on the condensercore body assemblies; modular design, standardization interfaces and a CAN bus technology are adopted for the electric control boxes, a cloud control technology is adopted for a controller, a power-on automatic detection technology is adopted for a high-voltage direct-current input end, and pressure and pressure release protection devices are arranged on high-pressure and low-pressure pipes. According to the top-mounted dual-air-returning air conditioner of the passenger car, multiple transition beams and multiple air hole adhesive strips are used for connecting the air conditioner with the car, multiple air conditioner interfaces are unified and simplified, standardization, environmental protection and light weight of products are achieved, the production efficiency can be improved, andthe modeling design of the passenger car is conducted conveniently.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of passenger car air conditioners, in particular to a light-weight top-mounted double return air passenger car air conditioner applied to large and medium-sized (10.5-12 meters) passenger cars. Background technique [0002] Urban transportation, long-distance transportation, and tourist vehicles almost all use large and medium-sized passenger cars. Today, with the development of society and the development of the automobile industry, passenger car air conditioners have almost become the standard equipment for newly produced large and medium-sized passenger cars. The installation methods of the existing large and medium-sized passenger car air-conditioning systems are basically top-mounted, rear-mounted, bottom-mounted and built-in. Considering the installation space, the convenience of maintenance and the easy replacement of parts, the top-mounted arrangement has become the main ch...

AI Technical Summary

Problems solved by technology

The existing passenger car air conditioner is time-consuming and laborious in terms of installation. It takes many people and a long time to complete the installation of a passenger car air conditioner, and it will produce some different product states.

In terms of materials, the glass fiber reinforced plastics used have the disadvantages of large volume and heavy weight, while aluminum alloy products have many parts, complex structures, and insufficient time-consuming processes.
