Description
Technical Field
The invention relates to the field of heat dissipation, in particular to a heat dissipation structure and a device with the same.
Background
With the development of science and technology, electronic equipment provides more and more abundant functions for users, but the heat generated by the electronic equipment in the operation process is also great, and the normal operation of the electronic equipment is influenced.
In products in the existing market, for example, light sources or light source modules for various purposes, the existing design is that the light sources are fixed, and a heat dissipation structure is generally configured for dissipating heat of the light sources, but due to the internal space limitation of the light source modules or the consideration that light rays of the light sources cannot be blocked, an unlimited number of heat dissipation structures cannot be arranged for dissipating heat of the light sources or the light source modules, so that the existing light sources or the light source modules often have the problem of poor heat dissipation. Therefore, a technical scheme that one or more fixed heat dissipation structures or heat dissipation structures can swing in a small amplitude is proposed, but even then, only certain specific positions of a certain area or certain areas of a light source or a light source module can be cooled, so that supercooling or overheating of individual positions of the surface and the inside of the light source is easily caused, the temperature difference between the upper part and the lower part of the light source is large, halogen tungsten circulation inside the light source is easily caused to be abnormal, the inside of the light source is blackened or whitened, the light extraction efficiency is influenced, and the service life is shortened; cycling of tungsten halide within the light source can further lead to increased stress on the lamp bulb and even to cold cracking or explosion of the lamp, with direct failure of the light source.
In addition, a gravity sensor is also proposed to reduce the temperature difference of the light bulb, and due to the fact that the specific gravity of air at different temperatures is different and the air is influenced by the shape of the light cup, the flow velocity of the heat dissipation airflow at each position in the light cup is different, and the temperatures of different areas on the surface of the light emitting bulb are different. When the lamp body shakes the head to different angles, the light-emitting bulb can change the surface temperature distribution area continuously due to the change of the gravity angle. After the gravity sensor is added, the actual elevation angle parameter of the lamp cap can be transmitted to the air supply device, and the air quantity is adjusted, so that the surface temperature of the light-emitting bulb is adjusted, and the effect of reducing the temperature difference of the lamp bulb is achieved.
The light source or light source module in the prior art faces various problems due to the inability of well-balanced heat dissipation, for example, during the tungsten halide cycle of the mercury lamp, tungsten inside the bulb is easily accumulated at a cooler position of the inner wall of the bulb, and due to the light-tight property of tungsten, the tungsten absorbs heat rapidly at the position, which in turn causes too high local temperature, which may cause an overheating reaction of bulb glass/quartz, such as whitening. This further increases the stress on the lamp ball, and eventually leads to fatal failures such as cold cracking and lamp explosion of the lamp ball due to excessive stress. Furthermore, mercury lamps are sensitive to overheating as well as to undercooling, since glass or quartz in mercury lamps have an upper temperature limit, and when a certain temperature is exceeded, the glass or quartz can cause devitrification, which affects light transmission, and can trap heat inside the light source and cannot be radiated out by light. In addition, because the light source is fixed in the product design in the prior art, when the light source works at a fixed angle for a long time, dust or other particulate matters are easy to accumulate on the surface area of the light source, the light transmission and the heat balance of the light source are influenced, and the adverse effect is caused on the light source.
