Problems solved by technology

[0004] For a long time, the domestic antenna array cooling technology has been relatively backward. Even if the array liquid cooling system is used to dissipate heat, there are still a large number of array cooling pipelines, and the pipelines will be entangled when they rotate with the antenna array on the servo turntable. , and the liquid-cooled pipeline can guarantee a stable flow, and its development is relatively lagging behind for these functions

Embodiment 1

[0035] Taking a certain transmitting array as an example, the transmitting array adopts the form of an active array, which is mainly composed of an array antenna, a transmitting feed network, a single power amplifier component, and an array power supply. The equivalent radiation power of this front is 1MW, and the heat generated by the entire emission front reaches 5100W. If forced air cooling is used for heat dissipation, the heat dissipation area that needs to be arranged is very large, and the number of fans used is large, and the entire emission front will occupy a large area. Space, bad for maintenance as well as convenience. For this reason, in the embodiment of the present invention, a liquid cooling system suitable for the servo turntable is proposed, wherein the cooling capacity to be provided by the cold source is 6KW, and the power of the cold source is 4KW, such as figure 1 As shown, it specifically includes: a transmitter case 7, at least one cold plate 8, a cold ...

Embodiment 2

[0046] Based on Embodiment 1, the difference between this embodiment of the present invention and Embodiment 1 is that the cold source further includes a sensor, which is arranged in the pipeline 4 between the pump and the heat exchanger for monitoring the liquid cooling medium temperature and / or pressure.

[0047] In a specific implementation manner of the embodiment of the present invention, the sensor is a temperature sensor 16, which is used to monitor the temperature of the liquid cooling medium in the cold source, and control the working status of the heat exchanger and the fan according to the monitored data;

[0048] In the second specific implementation manner of the embodiment of the present invention, the sensor is a pressure sensor 17, which is used to monitor the pressure of the liquid cooling medium in the cold source, and control the working state of the pump according to the monitored data;

[0049] In the second specific implementation manner of the embodiment...

Abstract

The invention discloses a liquid cooling system suitable for a servo turntable. The liquid cooling system comprises a transmitting case, a cold source, a fluid distributor, a first rotary water joint,a second rotary water joint and at least one cold plate, each cold plate is arranged in the transmitter box, and a cavity is formed in each cold plate; the fluid distributor is respectively communicated with each cold plate; the first rotary water joint comprises a first fixed part and a first rotary part which are communicated with each other, and the first fixed part is communicated with a coldsource through a pipeline; the second rotary water joint comprises a second fixed part and a second rotary part which are communicated with each other, the second fixed part is communicated with thefirst rotary part in the first rotary water joint through a pipeline, and the second rotary part is communicated with the fluid distributor and the first rotary part in the first rotary water joint. The servo turntable can rotate along with the servo turntable, the number of array surface pipelines can be reduced as much as possible, and uniform distribution of liquid supply flow is realized.

Description

technical field [0001] The invention belongs to the technical field of radar electronic heat dissipation, and in particular relates to a liquid cooling system suitable for a servo turntable. Background technique [0002] Due to its unique advantages, the active phased array antenna has become a research hotspot in various military powers in recent years. my country has also launched research on active phased array radar. A prominent problem of active phased array radar is that the component chips have a high heat flux density, which requires high cooling and heat dissipation. With the rapid development of electronic technology, the size of electronic components is getting smaller and smaller, the integration of power amplifier chips is getting higher and higher, and the heat consumption of antenna components is getting higher and higher. The local heat flux can exceed 150 watts per square centimeter. According to relevant research, it is predicted that the heat flux densi...
