光伏送變器作為電力電子設(shè)備，主要功能是把屋頂光伏發(fā)電組件產(chǎn)生的直流電轉(zhuǎn)換為交流電。因為其內(nèi)部有成千上萬的電子元器件，且大部分為熱源器件，因此散熱設(shè)計對逆變器壽命有極大影響。

As a power electronic device, the main function of a photovoltaic transformer is to convert the direct current generated by rooftop photovoltaic modules into alternating current. Because there are thousands of electronic components inside, most of which are heat source devices, the heat dissipation design has a great impact on the lifespan of the inverter.

人體的體感溫度在36℃左右，會有溫?zé)岣?在45℃左右會有燙熱感;在50℃左右長時間接觸會有燙疼感;在60℃時長時間接觸會形成燙傷。

The perceived temperature of the human body is around 36 ℃, and there will be a warm sensation; There will be a burning sensation at around 45 ℃; Prolonged exposure at around 50 ℃ may cause a burning sensation; Prolonged exposure at 60 ℃ can cause burns.

因為逆變器散熱的需要和工作環(huán)境（戶外陽光直射)的特殊性，安規(guī)標(biāo)準(zhǔn)規(guī)定逆變器外殼溫度不能超過70C，夏天外部環(huán)境溫度為40℃時，外殼溫度一般在55℃~60℃之間，因此人觸碰到送變器外殼時就會有發(fā)燙的感覺，但即使出現(xiàn)發(fā)熱，也不會造成燙傷。

Due to the need for inverter heat dissipation and the special working environment (direct sunlight outdoors), safety standards stipulate that the temperature of the inverter housing cannot exceed 70C. In summer, when the external environment temperature is 40 ℃, the housing temperature is generally between 55 ℃ and 60 ℃. Therefore, when people touch the inverter housing, they will feel hot, but even if there is heat, it will not cause burns.

為了更好、更快地降低元器件溫度，保證元器件更長的使用壽命，采用整體式外殼與散熱器緊密接觸的設(shè)計，使外殼成為系統(tǒng)欺熱的重要組成部分，散熱性能加強(qiáng)，外殼溫度較高，這屬于逆變器工作的正常現(xiàn)象。

In order to lower the temperature of components better and faster, and ensure a longer service life of components, a design is adopted that tightly contacts the integral shell and heat sink, making the shell an important component of the system for heat dissipation. The heat dissipation performance is enhanced, and the shell temperature is higher, which is a normal phenomenon of inverter operation.

由于夏季環(huán)境溫度較高，光伏逆變器工作之后溫度會更高，所以送變器的通風(fēng)工作就非常關(guān)鍵了，保障光伏送變器良好的通風(fēng)環(huán)境是非常重要的。

Due to the high ambient temperature in summer, the temperature of the photovoltaic inverter will be even higher after operation, so the ventilation of the transformer is crucial. Ensuring a good ventilation environment for the photovoltaic transformer is very important.
