Detailed Description
The technical solutions in the embodiments will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, the heat storage type heat pipe element provided by the present application includes a heat pipe element main body 10, and the heat pipe element main body 10 is a cavity with a certain vacuum degree, and a working medium is filled in the cavity. The heat pipe element main body 10 is divided into a condensation section 20 and an evaporation section 30, a partition plate 40 is arranged between the condensation section 20 and the evaporation section 30, the condensation section 20 is exposed and directly contacts with a cold fluid for heat exchange, a sleeve 50 is arranged outside the evaporation section 30, the sleeve 50 can be made of any metal material, the top of the sleeve 50 is welded and fixed on the partition plate 40, the bottom of the sleeve is sealed, a heat storage material 60 is filled inside the sleeve 50, a certain expansion space is reserved, the heat storage material 60 is used for storing heat and absorbing and releasing heat, and the outer side of the sleeve 50 directly contacts with the hot fluid.
The heat storage material may be a phase change heat storage material of any formulation, such as various inorganic salt hydrates, organic matters, or polymers, and a composite structure phase change material based on these materials, and the shape of the phase change material may be a powder shape, or may be any other geometric shape, and the application is not limited specifically herein. For example, JH series of high temperature phase change heat storage materials manufactured by jiangsu alloy energy technology ltd. The phase-change heat storage material is a known material, and the application of the material to the heat pipe element with the shape and the structure does not belong to the improvement on the material per se.
The condenser section 20 and/or the exterior of the sleeve 50 may be augmented with heat transfer enhancement structures including, but not limited to, fins, grooves, or bellows, etc.
When the heat storage type heat pipe element provided by the application absorbs heat, the heat is firstly conducted to the heat storage material 60 through the sleeve 50, the heat storage material 60 absorbs and starts to store the heat, and after the heat pipe element is started, the heat storage material 60 releases the heat to the heat pipe at the same time. The heat storage material has the characteristic of basically unchanged temperature when the phase change occurs, so that heat is stored, the evaporation section of the heat pipe element is at a constant temperature within a certain time, the condensation section can continuously and stably output heat, and the influence on the service life of the heat pipe and the whole set of heat exchange system due to fatigue caused by thermal stress can be effectively avoided.
The working principle of the heat storage type heat pipe element provided by the application is as follows:
when the temperature of the heat source is higher than the phase change temperature of the heat storage material 60, the sleeve 50 transmits heat to the heat storage material 60, the heat storage material 60 absorbs the heat and starts to heat up, when the temperature of the heat storage material 60 rises to the phase change temperature, the heat storage material 60 starts to change from a solid state to a liquid state, the phase change latent heat of the heat storage material 60 is used for storing the heat until all the heat storage material 60 becomes the liquid state, and the heat absorption is continued until the temperature of the heat storage material 60 approaches the temperature of the heat source. In the process, the evaporator section 30 simultaneously absorbs heat and transfers the heat to the condenser section 20 for heat exchange with the cold fluid. When the temperature of the heat source fluctuates at the phase change temperature of the heat storage material 60, the heat storage material 60 provides a stable temperature environment for the evaporation section 30 by utilizing the characteristic that the phase change temperature of the heat storage material is basically stable; when the temperature of the heat source is too low or even disappears, the heat storage material 60 continues to release heat, and the heat pipe is maintained to work normally. In the above process, the heat passes through the heat storage material 60 and then is subjected to heat exchange by the heat pipe element, and the heat storage type heat pipe element is suitable for the conditions that the temperature of a heat source is changed greatly, the heat output needs to be stabilized, and the like.
