Radiator, electric appliance box and air conditioner

Abstract

The invention discloses a radiator, an electric appliance box and an air conditioner. The radiator comprises a substrate, multiple first fins and multiple second fins, and the substrate is provided with a first heat dissipation area and a second heat dissipation area; the multiple first fins are arranged on the substrate, the first fins are distributed in the first heat dissipation area at intervals, and a first heat dissipation air channel is formed between every two adjacent first fins; and the second fins are arranged on the substrate and distributed in the second heat dissipation area at intervals, a second heat dissipation air channel is formed between every two adjacent second fins, the extending direction of the second heat dissipation air channels intersects with the extending direction of the first heat dissipation air channels, and all the second fins are located on one sides of air outlets of the first heat dissipation air channels. According to the radiator, the substrate is divided into the first heat dissipation area and the second heat dissipation area, the first heat dissipation air channels and the second heat dissipation air channels which intersect are formed in the first heat dissipation area and the second heat dissipation area respectively, and the problems that the air flow at the tail ends of the heat dissipation air channels is small and the temperature is high are solved through staggered streaming air.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a radiator, an electrical box and an air conditioner. Background technique [0002] The electronic components of the external unit of the inverter air conditioner are generally packaged in the electrical box to avoid potential safety hazards such as short-circuit burning of the motherboard or leakage of electricity due to contact with water and dust. When the unit is running in high temperature weather, the power device generates a lot of heat, and the closed protection structure makes it difficult to dissipate heat. The surface of the device is easy to quickly reach the temperature limit protection, resulting in frequent frequency reduction or crash of the unit, which seriously affects the normal use of users. Long-term high-temperature working environment will also adversely affect the reliability and life of electronic components. Designing a reasonable cooling solut...
