A cluster heat pipe heat exchanger

Abstract

The invention discloses a clustered type heat pipe heat exchanger which mainly comprises a first-grade heat pipe set, a second-grade heat pipe set and a third-grade heat pipe set, wherein the first-grade heat pipe set, the second-grade heat pipe set and the third-grade heat pipe set can be formed to be a four-N-grade heat pipe set as required; the whole system is divided into a condensing area, an insulation area and an evaporating area; the heat pipe set at each grade is structured as a row of independent sealed pipelines formed by connecting heat pipe units in parallel, and the numbers of heat pipe units to form the independent sealed pipelines for the heat pipe sets at different grades are the same, moreover, the heat pipe sets at various grades can be arranged side by side, and assembled into one same housing and share one air channel; the flowing directions of the air in the condensing area and the evaporating area are opposite, so that a refrigerant in the heat pipe at each grade can be served as the constant temperature liquid, then a heat exchanging device with the temperature varying effect can be achieved with the heat pipes at various grades; and furthermore, the heat exchangers at different grades have the same heat exchanging area, and the final discharge temperature is close to the environmental temperature, so that the heat utilization rate can be improved to the maximum; and the problems of high heat temperature difference loss and low whole heat exchanging efficiency of the traditional heat pipe heat exchanger can be solved.

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 cluster heat pipe heat exchanger formed by placing multiple sets of heat pipe devices side by side. Background technique [0002] The heat pipe uses evaporative cooling to make the temperature difference between the two ends of the heat pipe very large, so that the heat can be conducted quickly. Because of its excellent heat transfer performance and technical characteristics, it is widely used in the field of energy saving. At present, heat pipes are often used in the fields of equipment heat dissipation, waste heat recovery and fresh air systems. The total driving temperature difference of the heat pipe heat exchanger is the temperature difference between the evaporation section and the condensing section. The constant temperature characteristic of the refrigerant inside the single-stage heat pipe heat exchanger le...
