Description
Technical Field
The invention relates to the technical field of evaporators, in particular to an evaporator with high heat transfer efficiency.
Background
The refrigerating system consists of 4 basic parts, namely a compressor, a condenser, a throttling component and an evaporator. The four large pieces are connected into a closed system by a copper pipe according to a certain sequence, and a certain amount of refrigerant is filled in the system. A typical air conditioning refrigerant is freon, and conventionally R22 has been generally used, and some air conditioning freons have adopted a novel environment-friendly refrigerant R407. The above is a vapor compression refrigeration system. Taking refrigeration as an example, a compressor sucks low-temperature low-pressure freon gas from an evaporator, compresses the low-temperature low-pressure freon gas into high-temperature high-pressure freon gas, then flows through a thermostatic expansion valve (capillary tube), is throttled into low-temperature low-pressure freon gas-liquid two-phase objects, then the low-temperature low-pressure freon liquid absorbs heat from indoor air in the evaporator to become low-temperature low-pressure freon gas, and the low-temperature low-pressure freon gas is sucked by the compressor. After the indoor air passes through the evaporator, heat is released, and the temperature of the air is reduced. So that the compression, condensation, throttling, evaporation and repeated circulation are performed, and the refrigerant continuously takes away the heat of the indoor air, thereby reducing the temperature of the room. When heating, the flow direction of the refrigerant is changed by switching the four-way valve, so that the outdoor heat exchanger becomes an evaporator to absorb the heat of outdoor air, while the indoor evaporation becomes a condenser to radiate the heat indoors to achieve the purpose of heating
The evaporator is an important part in four major parts of refrigeration, and is also a dividing wall type heat exchange device. The low-temperature condensed liquid is subjected to heat exchange with the external air through the evaporator, and the vapor absorbs heat to achieve the refrigeration effect. The evaporator is divided into 3 types of normal pressure, pressurization and depressurization according to the operation pressure.
