specific Embodiment

[0027] The present invention is a heat dissipation design method for high-power millimeter-wave radar products. The main measures of the method are as follows:

[0028] The honeycomb hole design on the top cover of the product box. The purpose of the honeycomb holes is twofold, one is to provide ventilation inlets and outlets, and the other is not to affect the wireless transmission of radar waves when the holes are opened. Without affecting the propagation of radar waves, the aperture and spacing of the honeycomb holes are set to t must meet the following conditions:

[0029] Among them, n=1.2.3...; λm is the wavelength of the millimeter-wave radar wave in the air.

[0030] The left wall and the right wall of the product box have holes. The purpose of these two holes is to provide the entrance and exit of the ventilation channel. Since the two holes do not involve the transmission of radar wave wireless signals, there are no special requirements for the hole diameter and...

Embodiment 1

[0034] When the millimeter-wave radar product with box is working, the radar wave wireless signal passes through the honeycomb holes on the box cover. Since the hole diameter and hole distance are integer multiples of 1 / 2 wavelength, the wireless signal transmission is not affected.

[0035] As the temperature in the product box rises, the natural wind passes through the honeycomb holes from the top to the bottom, and then passes through the left and right vents to form ventilation convection channel A and ventilation convection channel B to achieve the purpose of heat dissipation. At the same time, the natural wind entering from the left / right passes through the empty area at the bottom and exits from the right / left vent, forming a convection ventilation channel D and a convection ventilation channel C to achieve the purpose of heat dissipation. It can be seen that the inventive design method can play a good role in heat dissipation, so that the millimeter-wave radar product c...

Abstract

The invention discloses a radar, particularly discloses a high-power millimeter-wave radar, and belongs to the technical field of design and manufacturing of electronic products. The invention provides a high-power millimeter wave radar which is relatively low in production cost and can effectively solve the problem of heat dissipation. The high-power millimeter wave radar comprises a radar body and further comprises a protection isolation heat dissipation assembly, and the radar body is arranged in the protection isolation heat dissipation assembly.

Description

technical field [0001] The invention relates to a radar, in particular to a high-power millimeter-wave radar, and belongs to the technical field of electronic product design and manufacture. Background technique [0002] In today's era, the operating frequency of electronic products is getting higher and higher, the functions are getting stronger and stronger, and the power consumption is also increasing. Solving the problem of heat dissipation has become an essential topic. Multi-transmission and multi-reception millimeter-wave radar not only has high power consumption, but at the same time, its key component - the radar antenna cannot be covered with green oil, which will seriously affect the performance. If it is completely exposed to the air, it will be easily oxidized, so the radar itself needs to be placed in a casing as a whole. in the box. This creates a paradoxical relationship of high power consumption, high heat generation and must be placed in a closed box, so t...
