Problems solved by technology

[0005] At present, the No. 60 coolant used by radar is mainly an inorganic type coolant. Some of the existing No. 60 coolants use sodium silicate additives. After a period of use, deposits and scales are likely to block the liquid cooling pipeline. Corrosive to equipment
However, other existing No. 60 coolants have poor adaptability to non-metallic materials and are prone to leakage.

Abstract

The invention provides multi-effect and low foam organic radar cooling liquid and application thereof, and relates to the technical field of cooling liquid. The radar cooling liquid is prepared from the following raw materials in parts by weight: 44-95 parts of ethylene glycol, 5-56 parts of deionized water, 1.0-4.5 parts of an organic composite corrosion inhibitor, 0.1-0.5 part of a pH buffer agent, 0.08-0.16 part of a rubber protective agent, 0.01-0.02 part of an antisludging agent, 0.00023-0.00028 part of a coloring agent and 0.002-0.003 part of defoaming agent. The cooling liquid generatesless foam, can achieve corrosion protection of multi-metal materials and solders of liquid cooling systems such as radars, has good adaptability with non metals, and has long service life. The cooling liquid has good application effects in liquid cooling systems such as military radars, airborne warning and control systems, aircraft carriers, electronic equipment and guided missiles, and specialair conditioners, central air conditioners, refrigeration houses, armoured vehicles, refrigeration equipment, vehicles and other low temperature environment equipment cooling systems.

Description

technical field [0001] The invention relates to the technical field of cooling fluid, in particular to a multi-effect, low-foaming organic radar cooling fluid and its application. Background technique [0002] Copper (T2 copper, HPb59-1 lead brass, etc.), stainless steel (1Cr17Ni2, 1Cr18Ni9Ti, 30CrMnSiNi2A, 316, 314 , 316L, etc.), cast iron, aluminum alloy (6063, 3A21, 5A05, 2A12, 7075, etc.) and other metal materials and different types of solder used in metal welding. In addition to the variety of metal materials, there are also many types of non-metal materials, such as: nitrile rubber (5171, 5870, 5470, 5080, etc.), EPDM rubber, silicone rubber, fluororubber, fluorosilicone rubber and sealing Glue, sealing ring and other non-metallic materials. Ordinary vehicle coolants cannot achieve anti-corrosion protection for a variety of metal materials and good adaptability to a variety of non-metallic materials. Liquid cooling systems such as radar and electronic equipment can...
