Description
技术领域Technical Field
本实用新型涉及双向逆变器领域，尤其涉及一种散热性能好的双向逆变器。The utility model relates to the field of bidirectional inverters, in particular to a bidirectional inverter with good heat dissipation performance.
背景技术Background technique
双向逆变器是一种可以将交流电转换为直流电，同时又可以将直流电转换为交流电的一种电气设备，其具备充电和逆变功能，但是这两项功能都具有较大的负载，因此PCB板上的变压器会产生一定热量，而双向逆变器内部的电子元器件对温度是非常敏感的，会导致内阻增大，工作效率变低，进而影响附近部分电子元器件的正常工作，加速绝缘层的老化，使双向变压器寿命变短，严重时还会烧毁变压器，所以双向逆变器的散热设计非常重要。A bidirectional inverter is an electrical device that can convert AC into DC and DC into AC at the same time. It has charging and inversion functions, but both functions have a large load, so the transformer on the PCB board will generate a certain amount of heat. The electronic components inside the bidirectional inverter are very sensitive to temperature, which will cause the internal resistance to increase and the working efficiency to decrease, thus affecting the normal operation of some nearby electronic components, accelerating the aging of the insulation layer, shortening the life of the bidirectional transformer, and even burning the transformer in severe cases. Therefore, the heat dissipation design of the bidirectional inverter is very important.
目前,双向逆变器的散热方式主要有两种：自然冷却和强制风冷，而市场上双向逆变器一般采用将PCB板裸露在外的方式，不仅散热效果不是很好，也不能很好地保护电子元器件，并且在运输也不具备一定的便携性，导致双向逆变器的寿命一般都比较短，严重时可能还会烧毁变压器，同时，一些非专业人员在使用过程中也会存在一定的安全隐患。At present, there are two main heat dissipation methods for bidirectional inverters: natural cooling and forced air cooling. However, the bidirectional inverters on the market generally expose the PCB board to the outside, which not only has a poor heat dissipation effect, but also cannot protect electronic components well. In addition, it is not portable during transportation, resulting in a generally short life of the bidirectional inverter. In severe cases, the transformer may be burned. At the same time, there are certain safety hazards when some non-professionals use it.
因此，本领域技术人员提供了一种散热性能好的双向逆变器，以解决上述背景技术中提出的问题。Therefore, those skilled in the art provide a bidirectional inverter with good heat dissipation performance to solve the problems raised in the above background technology.

The outer wall of the magnetic cover plate 203 is snap-fitted to the inner wall of the mounting shell 210, which ensures the beauty of the bidirectional inverter.
工作原理：该双向逆变器在安装时，需要将双向逆变器固定到壳体101内，再将两个散热片本体301卡进第一凹槽104后，卡扣302便会卡进卡架106上的卡槽105内，将耳扣304卡进第四凹槽103内，通过分别将凸块202卡接进第二凹槽102和第三凹槽305内，来安装顶板201，再将风扇箱209安装到安装壳210内，将风扇箱209的圆形槽208卡接到两个支撑柱206上，盖上磁吸盖板203，磁吸盖板203通过铁芯207磁吸效果固定，防止风扇箱209落灰，完成该双向逆变器的安装，然后风扇箱209可在控制板的控制下，启动风扇箱209，产生的冷风将会从吹风口205吹到发热的主板上帮助其散热，吸收热量的冷风将会从前端的通风口303吹出，后端的通风口303会进入新的冷空气，形成对流循环，从而增强的散热效果，在长时间使用下，如果双向逆变器的部分位置发生故障，可以对箱体机构1、风扇机构2和散热机构3进行分开拆除，通过手柄204可以方便拉开磁吸盖板203，对风扇箱209进行清理和维修，防止由于灰尘影响风扇盒的散热效果。Working principle: When installing the bidirectional inverter, the bidirectional inverter needs to be fixed to the housing 101, and then the two heat sink bodies 301 are inserted into the first grooves 104, and the buckles 302 are inserted into the slots 105 on the bracket 106, and the ear buckles 304 are inserted into the fourth grooves 103. The top plate 201 is installed by respectively inserting the protrusions 202 into the second grooves 102 and the third grooves 305, and then the fan box 209 is installed into the installation shell 210, and the circular grooves 208 of the fan box 209 are inserted into the two support columns 206, and the magnetic cover plate 203 is covered. The magnetic cover plate 203 is fixed by the magnetic effect of the iron core 207 to prevent the fan box 209 from falling dust, and the installation is completed. After the bidirectional inverter is installed, the fan box 209 can be started under the control of the control board, and the cold air generated will be blown from the air outlet 205 to the heated mainboard to help it dissipate heat, and the cold air that absorbs heat will be blown out from the front vents 303, and new cold air will enter the rear vents 303 to form a convection cycle, thereby enhancing the heat dissipation effect. After long-term use, if part of the bidirectional inverter fails, the box mechanism 1, the fan mechanism 2 and the heat dissipation mechanism 3 can be separately disassembled, and the magnetic cover 203 can be easily opened through the handle 204, and the fan box 209 can be cleaned and repaired to prevent dust from affecting the heat dissipation effect of the fan box.
