The object to be cooled in the embodiment of the present invention is not particularly limited, and may be, for example, the frequency conversion module 6 in the outdoor unit of the air conditioner. The frequency conversion module 6 of the air conditioner outdoor unit is provided with a plurality of high-power components, along with the miniaturization of the air conditioner outdoor unit and the requirement of diversification of functions of the air conditioner, the chip design of the air conditioner outdoor unit control module is more compact, the density of the components is continuously increased, and the volume of the components tends to be miniaturized. Therefore, the heating power consumption of the high-power components is larger and larger, and the heat flux density is increased sharply. In order to ensure the safety and reliability of the external machine electric control of the air conditioner, the heat dissipation performance of the frequency conversion module 6 is important. The existing method for improving the radiator of the frequency conversion module 6 of the outdoor unit of the air conditioner generally optimizes the body of the radiator, for example, increases the fin height, the fin number and other methods to improve the radiating area of the radiator, but because the space of the outdoor unit of the air conditioner is limited, the optimizing space of the radiator body is small, and thus the radiating performance of the radiator is limited. The embodiment of the invention provides a radiator with high heat dissipation capacity and two heat dissipation modules, which can timely dissipate heat generated by a frequency conversion module 6 and improves the reliability and stability of the operation of the frequency conversion module 6.
