Description
Technical Field
The utility model relates to a boiling heat transfer technology field, concretely relates to pond boiling heat transfer testing arrangement.
Background
Boiling heat transfer is an efficient phase-change heat transfer technology and plays an important role in the fields of seawater desalination, electronic device cooling, high-power laser thermal management, aerospace and the like. A large number of experiments and theories prove that the boiling heat transfer performance can be remarkably improved by constructing the micro-nano structure on the surface of the heating surface, namely the critical heat flow density and the heat transfer coefficient are improved. Therefore, in order to better study the micro-nano structure enhanced boiling heat transfer mechanism, it is very important to build a device of boiling heat transfer equipment in the pool, which is suitable for testing the surface heat transfer performance of the micro-nano structure. Although the boiling heat transfer curve is tested by utilizing the one-dimensional steady-state heat conduction principle, a unified testing method and a commercialized testing device are not available in the research field related to boiling heat transfer. Related boiling heat transfer test devices have been reported in the prior patents (CN103323488A and CN203337584U), but they still have the following problems: 1) the test workpiece is designed to be a cylinder, the test workpiece needs to be soaked in water in the test process, the test workpiece and the lower cover plate are sealed through silica gel, the surface temperature of the test workpiece gradually rises along with the progress of an experiment, and a gap is easily formed between the test workpiece and the silica gel due to the fact that the thermal expansion coefficients of the test workpiece and the silica gel are not matched, so that water leakage is caused; 2) the traditional test workpiece is connected with the main heat transfer column through threads, and the threads are coated with heat-conducting silicone grease which is easy to decompose and disperse at high temperature to emit peculiar smell and is not environment-friendly; 3) in a traditional boiling heat transfer device, test samples are mostly connected in a tight fit mode through heat conducting glue or by being welded on the surface of a copper test piece, and the connection mode of the heat conducting glue can not only generate higher interface contact thermal resistance, but also melt at high temperature, so that the critical heat flow density parameter cannot be tested; although the welding mode can measure the critical heat flux density, the existence of the interface contact thermal resistance can also influence the test precision; 4) in the traditional boiling heat transfer device, the whole equipment is large, the design is heavy, the operation is inconvenient, and the space utilization rate is low; 5) in the traditional boiling heat transfer device, a whole set of Teflon bases can be damaged when the critical heat flux density is reached, and the characterization cost is too high.
Four key points are involved in the boiling heat transfer test: 1) because the boiling sample surface needs to be soaked in a liquid working medium for testing, and the bottom of the boiling sample surface needs to be connected to a heater for heating, the key for success or failure of the experiment is how to carry out waterproof sealing; 2) how to conveniently replace different samples in the test process is also a problem to be solved; 3) compact and modular design of the equipment is necessary to improve the operation convenience and the space utilization rate; 4) how to realize the cyclic utilization of base many times, and then effectively reduce experiment test cost also is a problem that needs to solve.
