Problems solved by technology

[0005] In the patent application number 201310057042 "A Microchannel Cold Plate Design Method for Active Phased Array T / R Components", a microchannel cold plate structure for phased array T / R components is disclosed. The water-cooled heat sink adopts ordinary linear flow channels, which has limited heat dissipation capacity and simple overall installation structure. It does not consider the installation of large-scale phased array T / R components, nor does it consider the wiring of phased array T / R components. General Manufactured by specialized processing methods, mass production at low cost cannot be achieved

Embodiment 1

[0037] A three-dimensional fish-scale-like microchannel cold plate based on metal 3D printing technology. The phased array T / R components are distributed on the surface of the cover plate of the micro-channel radiator. The heat dissipation channel composed of 3, the water inlet 4 and the water outlet 5 are opened in the middle of the two sides of the radiator, the coolant enters from the water inlet 4, evenly passes through the arrayed fish scale-shaped protrusions 3 heat dissipation channels, and finally flows from the water outlet 5 out, complete a round of convection cooling in the radiator.

Embodiment 2

[0039] On the basis of Example 1, the microchannel cold plate 1 is installed on the mounting frame in turn, and for the heat dissipation of the heat source of the phased array T / R component, the heat source is installed on the cover of each layer of radiator through each through hole and wiring hole On the surface of board 2, coolant can be injected from the multi-interface blind plug water connector (water inlet) 7(a) of the mounting frame, each multi-interface blind plug water connector (water inlet) 7(a) and the multi-interface blind plug water connector The port of (water outlet) 7(b) corresponds to the water inlet 4 and the water outlet 5 of a microchannel cold plate. The cooling liquid enters the cold plate of each layer through the interface to conduct convection heat dissipation with the heat source, and then passes through the multi-interface blind plug water joint ( Outlet water) 7(b) flows out to complete the overall heat dissipation process of a round of laminated c...

Embodiment 3

[0041] The microchannel cold plate is provided with a cavity for cooling liquid to flow through. The cavity is composed of four arcs with a radius of 3mm. The specific design dimensions are shown in Figure 3(b). There are gaps, and the gaps between all block-shaped protrusions form microchannels, which are fish-scale-like in shape, and the specific structure is shown in Figure 3(a).

Abstract

The invention discloses a fish scale-like microchannel radiator and a radiator using the radiator, and relates to the technical field of radiators. The microchannel cold plate of the heat dissipation structure of the present invention adopts an imitation fish scale structure, the first half of the imitation fish scale raised structure selects a star structure, the pressure on the horizontal direction is small, the rear part adopts a shuttle structure, and the vertical direction can To withstand greater loads, the two structures are optimized and used in combination, and the force distribution of the cold plate is even. The imitation fish scale protrusions in the micro-channel cold plate are distributed in an array, and the design of tiny channels is adopted, which greatly enhances the pressure and speed of liquid flow. There is a certain interval between them, so as to avoid the excessive pressure in the local area and damage the structure and uniform temperature design. This structure allows the coolant to pass through the entire microchannel cold plate more evenly, and is aimed at the heat dissipation of the phased array T / R components. Compared with the runner structure, the heat dissipation capacity is stronger, and the temperature distribution after heat dissipation is more uniform.

Description

technical field [0001] The invention relates to the technical field of radiators, in particular to the design and installation of a bionic three-dimensional microchannel radiator of a phased array T / R assembly. Background technique [0002] Phased array T / R components are a collection of highly concentrated electronic components. Due to the limitation of its size and volume, under the requirements of miniaturization and densification, the power of the devices continues to increase, so its heating power will also increase accordingly , causing the heat flux to rise sharply during normal operation [2] . In the phased array T / R component, the T / R component is one of its important components, and it is also the main source of heat in the entire phased array T / R component, and the high power amplifier is the power of the T / R component Main heating element. With the further maturity of the microelectronics process, the transmission power of the high-power amplifier has increase...
