What do you see when choosing a small heater?mini fan heater

　　Mini air heaters/small air heater, are mainly small-power semiconductor heating materials that heat the air flowing through and heat the air after heating. Therefore, small air heaters are relatively safe and power-saving; It is easy to use. Put it on the desktop, connect the power supply, and turn on the switch to have warm air. If you want to warm your hand, you can adjust the direction according to the position of the product.

　　1. Key points of purchase: heating element

　　The main function of mini heater is heating, so when purchasing small heater, we should first look at the heating element.

　　First, look at the heating element materials and distinguish between ordinary electric heating wire small heater and PTC small heater. The cost of electric heating wire small heater is relatively low. Generally, the electric heating wire material is composed of iron chromium wire. It is a small heater with relatively low price and small power. The power is set at 1000W ~ 1800W, and the price of electric heating wire small heater is between 100 ~ 200 yuan; PTC small heater uses PTC ceramic sheet for heating, which has no light and no oxygen consumption in the process of use. In contrast, it has higher safety performance. It is a relatively high-end heating element material of small heater at present. The power setting is generally 1800W ~ 2000W, and the price of the product is generally 150 ~ 500 yuan.

　　Then compare the size of the heating element. From a perspective, the larger the heating element, the better the heat generation effect. Therefore, on the premise of identifying the heating element material, pay attention to the size of the heating component.

　　Finally, compared with the structure of heating elements, the structure of PTC ceramic sheet heating elements will affect the heating effect to a certain extent. At present, there are two kinds of PTC combinations: one is closed PTC heating body, and the other is hollow PTC heating body. The thermal effect of closed PTC is relatively concentrated, and the effect will be better. Specifically, it should be combined with the product power.

　　2. Key points of purchase: heater category

　　The purchase of small heater depends on the category. The setting of natural wind gear of small heater is ignored by many consumers, but from the perspective of product performance and use, the setting with natural wind gear is much more scientific than that without natural wind gear. Because PTC is a remote heating part, sudden shutdown under the premise of huge heat will lead to obvious heat decay of PTC ceramic sheet. After the PTC small heater is shut down, blow natural air for 1 minute to dissipate the preheating of the PTC heater, so as to reduce the heat decay of the heater and prolong the service life of the product.

　　3. Key points of purchase: listening to the working noise of the heater

　　When purchasing a small heater, listen to whether there is noise. The small heater is driven by the motor, and the motor operation will inevitably produce noise. The best way to identify the noise is to turn the power to the maximum gear and put your hand on the machine body to feel the vibration amplitude of the product. The greater the vibration amplitude, the greater the noise will be.

　　Overall, the effect of mini heater is OK. The mini heater heats up the air generated by low-power semiconductor heating. It is easy to use, saves power and has high safety. You can choose a suitable heater according to your own needs. What do you see when choosing a small heater? It depends on the type of heater, the working noise of heater, the power of heater and so on. I hope this can help you choose a suitable Mini heater.
