Embodiment Construction
[0019] The technical solutions and beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] figure 1 Shown is the effect diagram of the in-situ device with ventilation sunshade of the present invention. figure 2 Shown is a schematic diagram of composition and installation of the present invention. The present invention provides an on-site device 201 with a ventilation sunshade, which includes an on-site device main body 203 and a ventilation sunshade 202 . The on-site device main body 203 is placed on the ground or mounted on the back or on the upper part; the ventilation sunshade 202 is installed outside the on-site device main body 203 to cover the on-site device main body 203 . The manufacturing material of the ventilation sunshade 202 can be metal material or plastic material or rubber or epoxy glass fiber, and metal material is selected in this embodiment.

The invention discloses a local device with a ventilated sunshade cover, which mainly comprises a local device main body and a ventilated sunshade cover. The ventilation shade is installed and connected with the main body of the local device. After installation, the ventilation sunshade covers the upper and front, rear, left and right sides of the main body of the local device. When the device isinstalled and used outdoors, the ventilation shade shields the direct sunlight and prevents the direct sunlight from reaching the surface of the main body of the local device and causing an additionalincrease in the internal temperature of the main body of the local device. The louver area of the ventilation shade is designed so that the air inside and outside the ventilation shade can convect normally and take away the heat dissipated by the main body. The temperature rise inside the main body of the local device is effectively controlled by the double measures of avoiding the extra temperature rise of the main body of the local device and ensuring the air convection and heat dissipation, so that the internal equipment and devices of the device can be reliably operated.
Description
technical field [0001] The invention belongs to the field of electrical protection control, in particular to an in-situ device with a ventilation sunshade. Background technique [0002] At present, with the digital development trend of electrical control and protection devices, the structure of control and protection devices is becoming more and more compact, which provides a feasible condition for the outdoor installation of electrical control and protection devices. The on-site installation of control and protection devices can save the cost of installing small rooms or outdoor cabinets. [0003] However, the compactness of the control and protection device also brings about the problem that the internal temperature of the device is easy to rise during operation. Power electronic devices such as CPU, IGBT module and SiC module are all very sensitive to operating temperature. However, when the device is installed outdoors and exposed to sunlight, the irradiation of the de...
