Special evaporator for heat-pipe refrigerating hybrid air-conditioner

Abstract

A special evaporator for a heat-pipe refrigerating hybrid air-conditioner contains a finned pipe heat exchanger, a gas collecting pipe, a liquid distribution head, a liquid distribution pipe and a heat exchange pipe. The special evaporator is characterized in that a liquid collecting pipe is arranged between the heat exchange pipe and the liquid separating pipe, and the liquid separating pipe runs through the liquid collecting pipe to insert and stretch into the heat exchange pipe; the gas collecting pipe adopts a U-shaped pipe which is composed of a first rising vertical pipe, a second rising vertical pipe and an oil return bend pipe; and the heat exchange pipe is communicated with the first rising vertical pipe through the finned pipe heat exchanger. The special evaporator of the invention realizes the fusion of performance and safety of a vapor compression refrigerating mode and a heat-pipe natural circulation mode on the same evaporator through a special pipeline design, ensures oil return safety of the vapor compression refrigerating mode, and reduces the pipe resistance of the evaporator. The evaporator which is applicable to the heat-pipe refrigerating hybrid air-conditioning unit has simple structure, low cost and obvious effect, thus effectively solving the problems of oil return and resistance reduction of the unit, and improving the operating reliability and high efficiency.

Description

technical field [0001] The invention relates to a special evaporator for a heat pipe refrigeration compound air conditioner, which is suitable for a heat pipe refrigeration compound air conditioner unit and belongs to the field of refrigeration and air conditioning equipment. Background technique [0002] "Spaces requiring cooling throughout the year" refer to those spaces where the indoor heat generation is too large or the heat dissipation of the enclosure structure is too small. Air-conditioned rooms that provide cooling capacity throughout the year. In recent years, with the prosperity of our country's economy and the rapid development of communication, IT, finance, construction and other related industries, all kinds of cooling spaces throughout the year continue to grow at an alarming rate, including mobile base stations, IDC data room, computer room, server Machine room, inner area of ​​large public buildings, some craft workshops, etc. Taking mobile base stations a...
