Temperature control device and method for adjusting temperature in sealed equipment

Abstract

The invention discloses a temperature control device and method for adjusting a temperature in sealed equipment. The temperature control method comprises the following steps of: pre-defining detection areas, determining a temperature rise curve of each detection area through a sampling test, determining a fan speed regulation curve, and determining a relation curve of fan rotating speeds according to a temperature rise value of the sealed equipment and the temperature of a fan air inlet; when the sealed equipment is operated, obtaining the temperature rise values of the detection areas on the basis of temperature rise curves of the detection areas in a chassis according to an input current or an output current, and determining the temperature rise value of the chassis by using the temperature rise values of the detection areas; determining a target fan rotating speed under a current input parameter according to the temperature rise value of the chassis and the temperature of the air inlet; and adjusting a control parameter of a fan power source until the fan rotating speed reaches the target fan rotating speed on the basis of the fan speed regulation curve between the fan rotating speeds and a rotating speed control parameter according to the target fan rotating speed. When the temperature control is carried out by the temperature control device and method disclosed by the invention, the parameters to be detected are fewer, the temperature rise value can be predicted, and the fan rotating speeds can be adjusted in time so as to accurately control the temperature.

Description

technical field [0001] The invention relates to the technical field of power supplies, and in particular, to a temperature control device and a temperature control method for adjusting the temperature in an enclosed device. Background technique [0002] Power products belong to power electronic equipment, and the power tubes and other devices in the equipment will generate certain losses when they work, and most of these losses are converted into heat. In power supply products, power devices are generally placed in the power supply chassis. In order to ensure that the power tubes and other electronic components can work under the allowable ambient temperature, the equipment is often cooled by fans, and the power supply chassis will also have corresponding air inlets and air outlet. [0003] The temperature in the power chassis is generally controlled by the air-cooled fan, and the system's control of the temperature is generally reflected in the speed regulation of the fan....
