Description

Method for constructing electrode heat dissipation path of electronic cigarette Technical Field The invention relates to the technical field of information, in particular to a method for constructing a heat dissipation path of an electrode of an electronic cigarette. Background In the field of modern consumer electronics, electronic cigarettes are an emerging alternative smoking product, and the performance of the core component of the electronic cigarettes is directly related to user experience and product safety, and has a vital role. Especially on the key heating component of the electrode, the heat dissipation capability not only affects the service life of the product, but also is related to the stability and safety in the use process. However, the current electronic cigarette electrode on the market generally faces the problem of insufficient heat dissipation under the high-strength working environment, which has become a core bottleneck for restricting the development of the industry. The existing heat dissipation methods mostly rely on simple structural design or external natural heat dissipation, for example, by increasing external contact area or selecting materials with better thermal conductivity to improve heat dissipation. However, these methods tend to be difficult to work inside the micro-sized electrodes, especially in the context of high frequency heating, where the rate of heat build-up is far beyond the efficiency of natural heat dissipation. This limitation makes the electrodes prone to localized overheating during continued operation, thereby affecting overall performance and user experience. A further technical challenge is how to build an efficient heat dissipation path in a very small space. The size of the electrodes is usually only in the order of millimeters, which places extremely high demands on the fineness of the internal structure. If a tiny flow channel can be designed in the electrode, the cooling medium can be circulated, and the heat transfer efficiency can be greatly improved. However, the machining difficulty of the micro-channel is extremely high, extremely high precision is required, and the stability and durability of the channel in a complex working environment must be ensured. Further, because a single channel design may not cover the area of uneven heat distribution, it becomes a more complex problem how to construct an auxiliary structure outside the channel that can spread heat widely. For example, when the electrode is operated, the temperature of the region near the center of heat generation is highest, while the temperature of the edge region is lower, and if only micro channels are relied on, heat may not be uniformly distributed, resulting in that part of the region is still overheated. Therefore, how to construct a precise flow channel and effectively integrate an auxiliary heat dissipation structure in a millimeter-sized micro space at the same time is a key problem in the current electronic cigarette electrode design and manufacturing field, so as to solve the problems of uneven heat distribution and local overheating.
