Technical Field

The invention relates to the technical field of electric power machine room environment purification regulation and control equipment, in particular to an air heat exchange device for indoor environment purification regulation and control.

Background

In the operation process of electric power and electrical equipment, factors such as temperature, humidity and dust in equipment space often play a decisive role in the safe operation of the equipment. The three factors of temperature, humidity and dust are directly related to a series of problems of insulation aging, electronic component failure, heat dissipation failure, poor contact and the like. At present, traditional high-power air conditioner and fan are usually taken to the computer lab of electric power industry and are cooled down the processing, but because the computer lab space is great, the air conditioner energy consumption promotes by a wide margin, has increased manufacturing cost, brings into the computer lab after cooling the ambient air simultaneously in, though reduced the temperature of computer lab itself, but the entering of ambient air has increased the humidity in the computer lab, especially in coastal area, the condition is more serious, has caused harmful effects for the equipment in the computer lab.

disclosure of Invention

The invention aims to solve the problems of high energy consumption, poor effect and obvious side effect of the existing cooling equipment of the machine room, and provides the air heat exchange device for indoor environment purification regulation and control, which can realize cooling without external air entering the machine room, has low energy consumption, saves cost and avoids the damage condition of external humidity to the equipment in the machine room.

In order to achieve the purpose, the invention adopts the following technical scheme:

an air heat exchange device for indoor environment purification regulation comprises a shell, wherein an air inlet pipe, an air outlet pipe, a ventilation port and a cold air port are respectively arranged on the shell, a group of first fans are connected to the ventilation port, a group of second fans are connected to the air inlet pipe, the first fans and the second fans are connected with a controller through signal transmission lines, a temperature sensor is connected to the shell close to the ventilation port, and the temperature sensor is connected with the controller through the signal transmission lines;

A heat exchange unit is arranged in the shell and comprises a group of heat exchange tubes, a semicircular arc-shaped bent tube is connected between every two adjacent heat exchange tubes, the inlet of the heat exchange unit is connected with the air exchange port, and the outlet of the heat exchange unit is connected with the cold air port;

The shell in the air cooling channel is connected with a group of guide plates, each guide plate is arranged between two adjacent heat exchange tubes and faces the bent tube, the air inlet tube and the air outlet tube are respectively connected to two ends of the shell, and the air inlet tube and the air outlet tube face the space between the two guide plates on the outermost side and the inner wall of the shell.

furthermore, the shell is vertically arranged, the air exchanging port and the air outlet pipe are respectively connected to the lower part of the shell, and the cold air port and the air inlet pipe are respectively connected to the upper part of the shell.

furthermore, the heat exchange tube and the bent tube are copper tubes or aluminum tubes.

Furthermore, the outer walls of the heat exchange tube and the bent tube are provided with a layer of silver foil coating with good heat conductivity.

According to the technical scheme, the temperature inside the machine room is monitored in real time through the temperature sensor, when the temperature is higher than a certain specific value, the temperature sensor transmits signals to the controller, the controller simultaneously opens one or more groups of first fans and second fans, the first fans blow hot air in the machine room into the heat exchange unit through the air exchange ports, the second fans blow external cold air into the cold air channel through the air inlet pipe, the cold air moves along the flow guide plates, the hot air moves along the heat exchange pipes, heat is exchanged between the hot air and the cold air in the shell, the external air after heat exchange is discharged through the air outlet pipe, and the air in the machine room after heat exchange is discharged into the machine room through the cold air ports, so that the air cooling work of the machine room is achieved. The invention can monitor the temperature in the machine room in real time and carry out self-regulation, the inside and the outside of the equipment are isolated in a circulating way, the outside air can not enter the equipment and only exchanges heat, the structure is simple, the energy consumption is low, the cost is saved, and the damage of the temperature and the humidity to the equipment in the machine room is avoided.
