A method for discharging hot gas with high heat source

Abstract

The invention relates to a high heat source hot air exhausting method. The method includes 1, arranging a pressure gauge, a temperature detector and a variable air resistance coefficient coil, arranging a heat radiating pipe on the periphery of the multiple heat source environment, aligning the port of each heat radiating pipe to the variable air resistance coefficient coil of each heat source, arranging another pressure gauge at the port of each heat radiating pipe correspondingly, and arranging a plurality of fans at the air exhausting port of the ports of heat radiating pipes; 2, judging whether each heat source requires to radiate or not, and judging whether the heat radiating pipe radiates effectively or not. One variable air resistance coefficient coil is arranged at each heat source correspondingly, and the heat source can radiate in a targeted manner. The method can be widely applied in working conditions that a radiating device is mounted unreasonably, the on-site process is adjusted, the device is adjusted or radiating requirements are changed, and temperature adjustment in a targeted manner can be implemented according to radiating requirements by the on-site device and equipment.

Description

technical field [0001] The invention relates to a hot gas discharge method, in particular to a high heat source hot gas discharge method. Background technique [0002] With the rapid development of power electronics technology, in the power system, inverters, UPS (Uninterrupted Power Supply, uninterrupted power supply), active filters, reactive power compensation devices, various forms of converters and power conversion devices, etc. The equipment is used more and more, and all of them are placed in the MCC (Motor Control Center, the motor control center, that is, the power distribution room). Since many devices placed in the MCC have high power consumption, large heat generation and large radiation, the temperature inside the MCC is relatively high. However, among these devices, inverters and active filters have high requirements on the environment, and need to work in a relatively low-temperature indoor environment. When the equipment in the MCC is increased or decreased ...

AI Technical Summary

Problems solved by technology

[0004] However, the above technologies have the following problems to be solved: 1. It is necessary to choose a high-power induced draft fan to overcome the resistance along the way and local resistance, to ensure the negative pressure and flow rate along the heat dissipation pipeline and to ensure the heat dissipation effect, which usually causes relatively large energy waste ;2. If the heat dissipation effect of the air coil is relatively poor, the MCC needs to be equipped with a higher-power air conditioner to ensure the ambient temperature; 3. When the user adjusts the process or equipment, the originally designed and calculated air coil cannot be very good Adapt, the heat dissipation effect will be affected; 4. If a certain equipment that needs to focus on heat dissipation is arranged at the end of the heat dissipation pipe far away from the induced draft fan, the heat dissipation effect will be worse, which will seriously affect the normal operation of the equipment; 5. To solve the above Three problems, there is also a method of adding regulating valves at the heat dissipation branch to improve the flow rate characteristics of the cooling coil, but this method needs to add regulating valves and pressure sensors and other equipment, the construction cost and equipment maintenance cost are relatively high, and it cannot be solved at the same time Uniform flow velocity in the branch and heat dissipation of key equipment in the fourth question above
