Description

TECHNICAL FIELD

[0001] The utility model relates to radar equipment technical field more particularly, relate to a kind of radar heat dissipation air duct structure. BACKGROUND

[0002] The meaning of radar is "radio detection and ranging", that is, using the method of radio to find target and determine their spatial position, so radar is also called "radio positioning". Radar is an electronic device for detecting targets using electromagnetic waves. Radar transmits electromagnetic waves to illuminate targets and receives their echoes, thereby obtaining information such as the distance, range rate, azimuth, and altitude of the targets from the point of electromagnetic wave emission. Radar generates a certain temperature during operation, and needs to be cooled and ventilated.

[0003] After searching, the utility model patent with publication number CN219269394U discloses a radar heat dissipation air duct structure, which includes an inner shell, a radiator, and an outer shell. The inner shell is provided with a gas distribution channel. At least one opening is formed in the side wall of the inner shell, and the length direction of the opening is the same as that of the gas distribution channel and is in communication with the gas distribution channel. The radiator includes a connecting plate and multiple heat dissipation fins. All the heat dissipation fins are vertically arranged on one side of the connecting plate, and the end of the heat dissipation fin away from the connecting plate faces the opening. An exhaust channel is formed between the inner wall of the outer shell and the outer wall of the inner shell, and is in communication with the gap between all adjacent two heat dissipation fins. After the airflow entering the gas distribution channel passes through the opening, the airflow directly enters between the adjacent two heat dissipation fins, and the airflow reaching the rear part of the radiator is not heated and warmed by the structure of the front part of the radiator. Therefore, the heat dissipation effect of each region of the heat dissipation fins and the connecting plate is similar. However, the above-mentioned patent still has the following disadvantages: the airflow entering the gas distribution channel is not filtered, and the airflow contains dust, which adheres to the heat dissipation fins and the connecting plate, affecting the heat exchange effect. Moreover, the airflow in the gas distribution channel is not convenient to enter the opening, that is, the wind is not convenient to enter between the heat dissipation fins, and lacks air guiding, affecting the smooth flow of the airflow. Therefore, we propose a radar heat dissipation air duct structure. UTILITY MODEL CONTENTS
