The utility model relates to a power distribution cabinet with a modularized structure, and relates to the technical field of power distribution cabinets, the power distribution cabinet comprises a cabinet body, each mounting plate module is detachably provided with cooling and heat dissipation terminal boxes in a vertically staggered manner, the top surface of each cooling and heat dissipation terminal box is provided with an inverted L-shaped hoisting rod, the free end of each L-shaped hoisting rod is provided with a temperature sensor, and the temperature sensor is connected with the cabinet body. The temperature sensor extends to the position between the electric devices in the inner cavity of the cabinet body and is used for monitoring the temperature in real time, each air supply pipeline is connected with the adjacent cooling and heat dissipation terminal boxes through hoses, and the heat dissipation air source module conveys air into the cooling and heat dissipation terminal boxes through the air supply pipelines and the hoses and discharges the air from outlets of the cooling and heat dissipation terminal boxes. And blowing and heat dissipation are carried out on the electric device whose heat accumulation is monitored. The air flow path can be accurately controlled according to information fed back by the temperature sensor, it is ensured that cooling air only flows to areas with abnormal temperature, the heat dissipation efficiency is improved, and energy is saved.

This utility model discloses a heat exchange device and an electrical cabinet. The heat exchange device is used in a cabinet with a parallel cabinet surface and includes a shell and a heat exchange unit. A receiving cavity is formed inside the shell, and the shell has an exhaust port and a first air inlet. The heat exchange unit is placed in the receiving cavity. The heat exchange unit has an inner cavity communicating with the corresponding exhaust port and a cooling fan installed at the exhaust port. It includes two heat exchange sections and two baffles perpendicular to the X-axis direction. The two heat exchange sections are inclined relative to both the Y-axis and Z-axis directions. The two baffles connect the two heat exchange sections at their respective ends along the X-axis direction. The inner cavity is connected to the first air inlet only through air ducts. The cooling fan drives airflow from the first air inlet through each air duct to the exhaust port. The electrical cabinet includes the above-mentioned heat exchange device. This application still has high heat dissipation efficiency when the cabinets are parallel.

The invention relates to a fascia gun, comprising: a housing assembly comprising a first housing and a second housing, the first housing and the second housing being connected to define a mounting cavity; the shell connecting assembly comprises a reinforcing connecting part, the reinforcing connecting part is located in the mounting cavity, and the two ends of the reinforcing connecting part are connected with the first shell and the second shell correspondingly; the control panel assembly is mounted in the mounting cavity; the first fixing assembly is connected with the first shell so that the control panel assembly can be fixed to the position, corresponding to the installation cavity, of the first shell. And the first reinforcing part is connected between the reinforcing connecting part and the first fixing assembly and fixedly connected with the first shell, and the shell has the advantages of being convenient and fast to install and high in structural stability.

The invention discloses a mounting and adjusting system of a free-form surface ceramic tile roof and a construction method of the mounting and adjusting system, and aims to solve the problem that the positioning and mounting requirements of purlins cannot be met in an existing mounting mode of splicing the free-form surface ceramic tile roof on site by adopting prefabricated parts. The installation adjusting system comprises a purline support fixedly connected to the top of a building main body steel structure, a positioning purline movably connected to the purline support, a main keel and a secondary keel, the main keel and the secondary keel are sequentially connected to the top of the positioning purline through bolts, and an adapter of the purline support and a base plate of the positioning purline are provided with strip holes which correspond in position and are perpendicular to each other. When the two positioning purlines need to be arranged in an included angle mode, the positions of the bolts in the corresponding long-strip holes of the adapter and the positioning purline base plate are adjusted, and the installation positions and the installation directions of the positioning purlines are adjusted. The main keel is in bolted connection with the top of the positioning purline, and the auxiliary keel is in threaded connection with the top of the main keel through a bolt penetrating through the third long-strip-shaped hole, so that the curvature of the auxiliary keel is consistent with that of a pottery tile installation positioning curve.
