Thermal solution for vehicle air conditioner
Introduction of car air conditioner:
Vehicle air conditioner is composed of compressor, condenser, throttling element, evaporator, fan and necessary control components.
Most car air conditioners use heating elements such as compressors or frequency converters or DC-DC converters.
The heat dissipation and cooling structure of the heating element of the vehicle air conditioner mainly includes a low temperature cavity, a heating element cavity, a fan, and a heating element arranged on the heating element cavity.
In order to produce products with better performance, car air conditioner companies need to consider suitable adhesive solutions in addition to optimizing the product structure design of car air conditioners.
Adhesive requirements for car air conditioners:
- Strong adhesion and fixation to components;
- Excellent heat dissipation for heating components;
- Environmental protection, non-toxic, with testing certification and qualifications;
- Moisture-proof, anti-static, dust-proof, mildew-proof, salt-fog resistance, etc. for circuit boards.
Glue scheme for vehicle air conditioner:
| dot with glue | glue program | Program Features |
| Radiator cooling | Thermal Grease | It has good thermal conductivity, temperature resistance and insulation properties. It is an ideal dielectric material for heat-resistant devices, and its performance is stable. It will not generate corrosive gas during use and will not affect the metal it contacts. |
| Electronic Components | adhesive sealant | High bonding strength, environmental protection, non-toxic, excellent anti-cold and heat alternating performance, anti-aging performance and electrical insulation performance, excellent moisture resistance, shock resistance, corona resistance, anti-leakage performance. With testing certification and qualification |
| circuit board | Three-proof glue | Good protection performance and high and low temperature resistance, need to be moisture-proof, anti-static, shock-proof, dust-proof, mildew-proof, anti-salt spray and other properties |
According to the structure, material, shape, sizing environment and process of vehicle air-conditioning products, the specific glue requirements are also different. For more glue solutions and quotations, please contact Cohetion.
