Description
技术领域technical field
本发明属于空气调节技术领域,具体涉及一种控制器盒、压缩机、空调器、车辆。The invention belongs to the technical field of air conditioning, and in particular relates to a controller box, a compressor, an air conditioner and a vehicle.
背景技术Background technique
纯电动车的空调是电动车上不可缺少的一部分,但是现在车用空调一般都是定频车用空调,定频车用空调具有能耗高,能效低的缺点,因此发展变频车用空调是现在车用空调行业的一大发展方向,但是变频车用空调的变频压缩机控制是行业中的一个难点。因为变频压缩机的控制器所需要的变频控制模块在使用过程中发热量巨大,必须具备优良的散热条件才能够使用。The air conditioner of the pure electric vehicle is an indispensable part of the electric vehicle, but now the vehicle air conditioner is generally a fixed frequency vehicle air conditioner. The fixed frequency vehicle air conditioner has the disadvantages of high energy consumption and low energy efficiency. At present, a major development direction of the vehicle air conditioner industry, but the inverter compressor control of the inverter vehicle air conditioner is a difficult point in the industry. Because the inverter control module required by the controller of the inverter compressor generates a huge amount of heat during use, it must have excellent heat dissipation conditions before it can be used.
目前行业一般都是采用的横向或纵向的简单散热片结构,若依靠自然风对流散热,则要求更高的散热片尺寸,若采用增加风机进行主动散热方式,则需要增加成本,同时当风机损坏时会导致散热能力急速下降的问题,降低了可靠性。一般车用空调控制器盒为铸铝盒,开模后散热片结构无法更改,导致控制器盒安装方向受到限制,通用性低。同时当车辆在行驶时,处在不同空间位置,外部风向的改变,可能会导致散热片无法进行有效散热,也即目前的控制器盒的散热翅片设置方向导致其在特定风向下的散热效果较好,而在特定风向之外的风向上其不能有效进行散热,基于此种不足,提出本发明。At present, the industry generally adopts a simple horizontal or vertical heat sink structure. If relying on natural wind convection heat dissipation, a higher heat sink size is required. If the fan is used for active heat dissipation, the cost will be increased. It will cause the problem of rapid decline in heat dissipation capacity and reduce reliability. Generally, the car air conditioner controller box is a cast aluminum box, and the structure of the heat sink cannot be changed after the mold is opened, resulting in a limited installation direction of the controller box and low versatility. At the same time, when the vehicle is driving, it is in different spatial positions, and the change of the external wind direction may cause the heat sink to be unable to effectively dissipate heat. That is to say, the setting direction of the heat dissipation fins of the current controller box causes its heat dissipation effect in a specific wind direction. It is better, but it cannot effectively dissipate heat in the wind direction other than the specific wind direction. Based on this deficiency, the present invention is proposed.
