Description

空调器及其电器盒Air conditioner and its electrical box 技术领域Technical field
本发明涉及空调设备技术领域,特别涉及一种空调器及其电器盒。The invention relates to the technical field of air conditioners, and in particular to an air conditioner and an electrical box thereof.
背景技术Background technique
随着空调技术的发展,空调设备在不断突破在极限环境下的制冷制热技术。为了确保空调器的电器盒稳定运行,需要对其内部的元器件进行降温,从而使空调可靠的运行。With the development of air-conditioning technology, air-conditioning equipment is constantly breaking through the cooling and heating technology in the extreme environment. In order to ensure the stable operation of the electrical box of the air conditioner, it is necessary to cool the internal components to ensure the reliable operation of the air conditioner.
电器盒的内部散热主要是通过在电器盒的盒体上进行通风风道的设计,使得外界空气进入电器盒内部,通过空气对流降低元器件表面的温度。The internal heat dissipation of the electrical box is mainly through the design of the ventilation duct on the box of the electrical box, so that the outside air enters the inside of the electrical box, and the temperature of the surface of the component is lowered by air convection.
但是,由于设置通风风道,外界水汽及灰尘等杂质极易通过风道进入电器盒内部,引发元器件腐蚀、电路短路等问题,影响电器盒的使用寿命;并且,虫鼠等小动物也有可能通过风道进入电器盒内,对电器盒内部结构进行破坏,同样影响电器盒的使用寿命。在长期使用过程中,容易出现风道堵塞的问题,导致电器盒内部的元器件无法进行空气对流降温,导致元器件过热损坏,从而影响电器盒的稳定运行。However, due to the provision of ventilation ducts, impurities such as external water vapor and dust can easily enter the interior of the electrical box through the air duct, causing problems such as corrosion of components and short circuits, affecting the service life of the electrical box; and small animals such as pests and rats are also possible. Through the air duct into the electrical box, the internal structure of the electrical box is destroyed, which also affects the service life of the electrical box. In the long-term use process, the problem of air duct blockage is prone to occur, and the components inside the electrical box cannot be cooled by air convection, which causes overheating damage of the components, thereby affecting the stable operation of the electrical box.
因此,如何避免元器件过热损坏,提高电器盒的使用寿命,确保电器盒的稳定运行,是本技术领域人员亟待解决的问题。Therefore, how to avoid overheating damage of components, improve the service life of the electrical box, and ensure the stable operation of the electrical box are problems that need to be solved by those skilled in the art.
