Multistage separated heat pipe

Abstract

The invention discloses a multistage separated heat pipe. The multistage separated heat pipe comprises a first stage heat pipe group, a second first stage heat pipe group, a third first stage heat pipe group, a heat pipe unit and a connection pipeline. The pipe can be manufactured into N stage heat pipe groups. A whole system is composed of condensers, evaporators and gas-liquid mixing channels; the evaporators and the condensers of each stage heat pipe group are a group of independent circulation loops formed by parallel connection of an identical number of heat pipe units; and the evaporators of the system are arranged under the condensers, and the gas-liquid mixing channels communicate top ends of the evaporators of each stage with bottom ends of the condensers. The evaporators and the condensers of the system are separated, long-distance heat transfer can be achieved, great flexibility is provided for a technological design, and good conditions are created for large-scale devices, comprehensive utilization of heat energy and optimization of heat energy utilization systems.

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 split heat pipe formed by arranging multiple sets of independent heat pipe devices side by side. Background technique

[0002] The heat pipe uses evaporative refrigeration 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 superior heat transfer performance and technical characteristics, it is widely used in the field of energy saving. At present, heat pipes are commonly used in equipment cooling, 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 condensation section. The constant temperature characteristic of the refrigerant inside the single-stage heat pipe heat exchanger leads...
