Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0019] The T-shaped air duct cooling device adopting trapezoidal cooling fins provided by the present invention includes a casing, a rectangular parallelepiped radiator, an L-shaped square tube and an exhaust fan.

[0020] The cuboid radiator is a hollow cuboid, with openings on both ends of the axial direction, as an air inlet, and an air outlet in the middle of the side wall; a number of evenly arranged trapezoidal radiators are fixed on the opposite side walls of the cuboid radiator cavity. The two side walls and the side wall where the air outlet are located are perpendicular to each other, and the trapezoidal heat sink is divided into two sections perpendicular to each other, and the section perpendicular to the side wall where the air outlet is located is a rectangular...

Abstract

The invention provides a T-shaped air duct cooling device applying trapezoid cooling fins. The T-shaped air duct cooling device comprises a shell, a cubic heat sink, an L-shaped square pipe and an air suction fan, wherein the cubic heat sink is a hollow cuboid, air inlets are arranged at two axial ends, an air outlet is formed in a side wall, a plurality of trapezoid cooling fins are fixedly arranged on two side walls, opposite and perpendicular to the air outlet, of an inner cavity of the trapezoid cooling fins and are arranged uniformly, a rectangular plate is arranged at one segment, perpendicularly facing the air outlet, of each trapezoid cooling fin, a right trapezoid plate is arranged at one segment parallel to the air outlet, an upper bottom edge of the right trapezoid plate perpendicularly faces the air inlet near to the rectangular plate, the air outlet is communicated with the air suction fan through the L-shaped square pipe, T / R modules are arranged at outer sides, fixedly connected with the trapezoid cooling fins, of two side walls, and the T / R modules are sealed between the air inlets and the air outlet of the heat sink. The T-shaped air duct cooling device has the advantages of simplicity in structure, small size, light weight and balanced cooling effect, and is easy to process, and the three-protection requirement of an active phased array radar can be met.

Description

technical field [0001] The invention relates to the field of heat dissipation of electronic equipment, in particular to a heat dissipation device of a T / R component in an active phased array radar. Background technique [0002] Any electronic equipment must be stored or worked under certain environmental conditions, and the influence of temperature on electronic equipment is particularly important. The T / R component in the active phased array radar puts forward high requirements for cooling and thermal control. Feasible cooling methods and excellent cooling effects have become one of the important foundations for radars to meet the requirements of high reliability indicators. The heat dissipation methods currently applied to T / R components mainly include forced liquid cooling and forced air cooling. The structure of forced liquid cooling is more complicated, and a complete liquid cooling system is required. Its weight and volume are relatively large, and it is not suitable ...
