Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange condensers, in particular to an ethylene glycol heat exchange condenser. Background Art

[0002] Ethylene glycol, commonly known as glycol, has a wide range of uses. It can be used to synthesize polymer compounds such as "polyester" (Dacron), and can also be used as raw materials for films, rubber, plasticizers, desiccants, brake oils, etc. It is also a commonly used high-boiling point solvent. The freezing point of its 60% aqueous solution is -40°C, so it can be used as an antifreeze for car radiators in winter and a refrigerant for aircraft engines. Ethylene glycol can also be used as a wetting agent for cellophane, fiber, leather, and adhesives. Later, people found that the performance of ethylene glycol aqueous solution is good. At a certain proportion, the freezing point can reach below -60°C, and the boiling point is above 110°C. It will not damage rubber hoses, and will not corrode metals after adding rust inhibitors. It is relatively cheap and has no unpleasant odor. Therefore, this liquid is currently widely used as a circulating medium for automobile cooling systems and is called automobile antifreeze.

[0003] At present, when ethylene glycol is heat exchanged in a heat exchange condenser, most of the time, a condenser, which is a separate heat exchange device, is used for the purpose of heat exchange condensation.
