Description

Technical Field

[0001] The utility model relates to the field of attenuator heat dissipation, and more specifically, to an attenuator with high heat dissipation performance. Background Art

[0002] An attenuator is an electronic device used to reduce signal strength. It is often used to adjust the amplitude of a signal or attenuate noise. In microwave technology, attenuators usually use structures such as microwave transmission lines or couplers to achieve signal attenuation. Attenuators generate a lot of heat during use. If the temperature of the attenuator is too high, it may cause damage to internal components and affect its use. Therefore, current attenuators must have a heat dissipation function to be used normally.

[0003] After searching, the existing patent (publication number: CN215184472U) discloses an attenuator with heat dissipation function, including an attenuator body, a heat dissipation shell is provided on the outside of the attenuator body; a signal input head and a signal output head are provided at both ends of the attenuator body; a spirally wound cooling water pipe is provided on the outside of the attenuator body; the heat dissipation shell is composed of a bottom shell and an upper shell; a plurality of groups of evenly distributed heat dissipation fins are provided in the bottom shell, and the cooling water pipes and the heat dissipation fins are staggered; a heat dissipation fan and a temperature sensor are provided inside the upper shell, and a water tank and a variable speed water pump are provided on the top of the upper shell; through the setting of the heat dissipation fan, the effect of wind heat dissipation is achieved; through the setting of the cooling water pipe, the water tank and the variable speed water pump, the effect of water cooling is achieved; through the setting of the temperature sensor, the temperature sensor controls the start and stop of the heat dissipation fan and the variable speed water pump according to the temperature of the attenuator, thereby realizing low-consumption and high-efficiency heat dissipation, thereby further improving the use efficiency and service life of the attenuator.

[0004] The existing attenuator cools down by condensation when performing heat dissipation work. The cooling effect and efficiency of this method are relatively low. If the attenuator load is larger, it cannot be effectively cooled by this device. Therefore, it is necessary to set the cooling structure as an evaporative heat absorption structure, blow the water mist on the surface of the attenuator by a blower fan, and then conduct the heat on the surface to the air inside the device, and finally discharge it through the outlet pipe, which can greatly improve the heat dissipation effect and efficiency of the attenuator.

[0005] Therefore, in order to solve the above problems, an attenuator with high heat dissipation performance is proposed. Utility Model Content
