Multistage power heat pipe system

Abstract

The invention discloses a multistage power heat pipe system which is mainly composed of a first stage power heat pipe unit, a second stage power heat pipe unit, a third stage power heat pipe unit, an evaporator fan, a condenser fan, a heat exchanger and a circuit control element which can be manufactured into a 4-N stage power heat pipe. Each stage of power heat pipe unit is an independent circulation loop, all evaporators are arranged side by side and assembled in an air flue of a same casing and share one evaporator fan, and all condensers are arranged side by side and assembled in the air flue of the same casing and share one condenser fan. Therefore, the multistage power heat pipe system is formed, and refrigerating fluid in each stage of the heat pipe is regarded as constant temperature fluid, so that the multistage heat pipe can achieve the effect of alternating temperature. Heat exchange areas of each stage of the heat exchanger are same, and final discharge temperature is close to ambient temperature, so that heat using ratio is improved to the maximum limit, and problems that the existing heat pipe heat exchange temperature difference is big in loss and low in total heat exchange efficiency.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a novel heat pipe heat exchange system, in particular to a multi-stage power heat pipe system in which a plurality of independent power heat pipe devices are connected in parallel. Background technique [0002] In information equipment rooms and base station buildings, the heat generated by indoor equipment is very large, reaching 200~1000W / m 2 . In addition, indoor IT equipment runs 8760h throughout the year, so cooling is required throughout the year in most cases, and its air conditioning consumes a lot of energy, often accounting for 40% to 50% of the overall energy consumption of information equipment rooms and base stations. Traditional computer room air conditioners use compressor cooling to run throughout the year. In fact, in winter or transitional seasons, when the outdoor temperature is lower than the indoor temperature, the outdoor low-temperature air can be us...
