Abstract

The invention provides a low-conductivity dielectric cooling liquid for an ethylene glycol type phased array radar, and an application of the low-conductivity dielectric cooling liquid, and relates tothe technical field of cooling liquids. The radar dielectric cooling liquid is prepared from the following raw materials in parts by weight: 66 to 68 parts of ethylene glycol; 32 to 34 parts of deionized water; 2.0 to 4.5 parts of an organic nonionic composite corrosion inhibitor; 0.08 to 0.16 part of an organic non-ionic rubber protective agent; 0.01 to 0.02 part of a scale inhibitor; and 0.002to 0.003 part of a defoaming agent. The cooling liquid is low in conductivity, capable of achieving corrosion protection of multi-metal materials and welding flux of liquid cooling systems such as radars, good in non-metal adaptability and long in service life; and the cooling liquid has a good application effect in liquid cooling systems such as military radars, airborne radars, early warning aircrafts, aircraft carriers, electronic equipment, guided missiles and the like.

Description

technical field [0001] The invention relates to the technical field of cooling liquid for phased array radar, in particular to a low-conductivity dielectric cooling liquid for ethylene glycol phased array radar and its application. Background technique [0002] Copper (T2 copper, HPb59-1 lead brass, etc.), stainless steel (304, 316, 316L, etc.), aluminum alloys are widely used in liquid cooling systems of military phased array radars, early warning aircraft, shipboard radars, and airborne radars. (6063, 3A21, 5A05, etc.) and other metal materials and different types of solder used in metal welding. In addition to many types of metal materials, there are also many types of non-metal materials, such as: nitrile rubber (5171, 5870, etc.), O-rings (EPDM rubber, fluorosilicone rubber), silicone rubber, fluororubber, etc. Various non-metallic materials. Although traditional radar coolants can protect the above-mentioned materials, they are all conductive and cannot protect the e...
