Description
技术领域technical field
本发明属于电散热器技术领域，特别涉及一种空气对流电散热器。The invention belongs to the technical field of electric radiators, in particular to an air convection electric radiator.
背景技术Background technique
目前现有的电散热器，有外壳体和电加热元件组成，外壳体有前板、后板、出风口、进风口，在外壳体内部设有电加热元件，电加热元件的主发热面与外壳体的前板、后板平行，电加热元件是面状发热，在电散热器工作时，大部分热量都通过辐射直接传递到外壳体的前板和后板上，小部分被加热的空气从外壳体的上部出风口排出；这就造成现有电散热器的对流效率很低，房间升温速度慢，耗电多，运行费用高；升温不均匀、局部燥热，房间内空气干燥、不舒适；而且造成外壳体的表面温度非常高（在90℃），极烫，容易对人员(尤其是老人及儿童）造成烫伤，产生安全隐患，尤其不适合老年人比较多的养老院、福利院及儿童比较多的幼儿园及中学、小学等场所；由于电散热器外壳体的表面温度非常高，还造成在电散热器加热和停止加热的交替工作过程中，由于壳体的热胀冷缩而产生较大的异常噪声，容易惊扰室内人员。At present, the existing electric radiator consists of an outer shell and an electric heating element. The outer shell has a front plate, a rear plate, an air outlet, and an air inlet. An electric heating element is arranged inside the outer shell. The front plate and rear plate of the outer shell are parallel, and the electric heating element generates heat in a planar manner. When the electric radiator is working, most of the heat is directly transferred to the front plate and the rear plate of the outer shell through radiation, and a small part of the heated air It is discharged from the upper air outlet of the outer shell; this results in the low convection efficiency of the existing electric radiator, slow room temperature rise, high power consumption, and high operating costs; uneven temperature rise, local hotness, dry and uncomfortable air in the room ; and the surface temperature of the outer casing is very high (at 90°C), which is extremely hot, and it is easy to cause burns to personnel (especially the elderly and children), resulting in potential safety hazards, especially not suitable for nursing homes, welfare homes and children with more elderly people There are many kindergartens, middle schools, primary schools and other places; because the surface temperature of the outer casing of the electric radiator is very high, it also causes relatively high temperature due to the thermal expansion and contraction of the casing during the alternate working process of heating and stopping the heating of the electric radiator. Loud abnormal noise can easily disturb the indoor occupants.
