Description

technical field [0001] The invention relates to a refrigeration system, in particular to a water-cooled heat pipe energy-saving refrigeration system with double cooling sources. Background technique [0002] The heat pipe is a heat transfer element with high thermal conductivity. It transfers heat through the evaporation and condensation of the working fluid in the fully enclosed vacuum tube shell. It has extremely high thermal conductivity, good isothermal performance, and heat transfer on both sides of the cold and hot It has a series of advantages such as the area can be changed arbitrarily, long-distance heat transfer, and temperature control. Heat pipe technology began to be mainly used in the aerospace field. my country began to study heat pipes in the 1970s. Since the 1980s, heat pipe gas-gas heat exchangers, heat pipe gas-water heat exchangers, heat pipe waste heat boilers, Heat pipe steam generator, heat pipe hot blast stove and other heat pipe products. The heat p...

Problems solved by technology

However, most of the heat exchangers in the prior art use the air-cooled heat pipe refrigeration system, which has the following disadvantages: 1) the energy efficiency ratio is low compared with the water-cooled type, 2) the installation conditions are limited, and the air-cooled heat pipe refrigeration system The condenser must be installed outdoors because of the need for natural cold wind, and the evaporator must be installed indoors. The distance between the two cannot be too long. Too long will seriously affect the cooling capacity of the equipment. 3) The working conditions of the heat pipe must be higher than the outdoor temperature. The indoor temperature is low, and it is generally required to be lower than 3°C, so it cannot be used all year round in many areas. Therefore, a new equipment is urgently needed to solve the above technical problems
