Embodiment Construction
[0027] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0028] Such as figure 1 As shown, the separated heat pipe heat exchange system of the present invention includes a combined evaporation section 1 installed inside the cave close to the high-temperature thermal fluid, a steam collection box 2, a steam circulation pipe 3, and a condensation section installed in the atmospheric environment outside the cave. 4. Liquid separation box 5 and liquid circulation pipeline 6.
[0029] The steam circulation pipe 3 connects the combined evaporation section 1, the steam collection box 2 and the condensation section 4 into a connected whole, so that after the steam passes through the combined evaporation section 1 and the steam collection box 2, it flows to the condensation section 4 for condensation; the liquid circulation pipe 6. Connect the condensation section 4, the liquid separation box 5 and the combined evapor...

A separate heat pipe heat exchange system for reducing the infrared radiation of high-temperature caves, including a combined evaporation section, a steam collection box, a steam circulation pipeline, a condensation section, a liquid separator box, a liquid circulation pipeline, etc., the liquid circulation pipeline and the evaporation section The inlets are connected to form a loop. The combined evaporation section includes at least two sets of evaporators for heat absorption, which can be determined according to the cooling requirements and the temperature difference between the inside and outside of the cave; the condensation section outside the cave is arranged at a higher height than the evaporation section to ensure liquid backflow. The present invention can realize stable operation when the temperature difference between the inside and outside of the cave is large (50°C-60°C) or small (25°C-30°C), and the temperature of the hot fluid discharged from the high-temperature cave body can be reduced to close to The ambient temperature outside the cave can greatly reduce the infrared radiation characteristics. The system of the invention has a simple structure, does not require additional power for system operation, has low energy consumption but high heat exchange efficiency, and has the advantages of simplicity, reliability, easy realization, energy saving and environmental protection compared with other heat transfer equipment.
Description
technical field [0001] The invention belongs to the technical field of heat pipes, and relates to a device and a system for reducing the temperature of thermal fluid discharged from a high-temperature cavity. Background technique [0002] At present, some important base facilities are generally arranged in places with good concealment conditions such as mountains, deserts, underground, etc., in order to avoid the detection and infrared detection of reconnaissance aircraft or satellite radar. Large-scale engineering caves have been opened in these places to carry out corresponding production, experiment and defense tasks. Due to the heat source inside the engineering cave, the temperature of the airflow out of the cave is significantly higher than the ambient temperature. If the temperature of the fluid at the exit of the cave is too high, it will show obvious infrared radiation characteristics, which is easy to be detected by infrared detection, which will bring great safet...
