Temperature control system for ageing cabinet for multiple direct-current power supplies

Abstract

The invention discloses a temperature control system for an ageing cabinet for multiple direct-current power supplies. The ageing cabinet for the multiple direct-current power supplies comprises an ageing cabinet body with a base, wherein a heating tube is arranged in the base; a multi-layer ageing rack is arranged in the ageing cabinet body; a plurality of power supply sockets are arranged on each layer of ageing racks; circulating air flues are arranged on the side surface and the top of each aging rack; circulating air blowers are arranged in the circulating air flues; cooling air flues are arranged at the peripheries of the circulating air flues; solenoid valves and cooling fans are arranged in the cooling air flues; the temperature control system comprises a DSP (digital signal processor) module, an input end of the DSP (digital signal processor) module is connected with a button operation circuit module and a plurality of temperature sensors; an output end of the DSP (digital signal processor) module is connected with an LED (light-emitting diode) display, a heating tube relay, a circulating fan driver, a solenoid valve driver, a cooling fan driver and a sound-light alarm circuit module. The temperature control system can be used for regulating the temperature in the cabinet body of the aging cabinet in real time, and is high in working reliability and stability.

Description

technical field [0001] The invention relates to the field of power supply technology, in particular to a temperature control system for multiple DC power aging cabinets. Background technique [0002] As a power supply device for electronic equipment, DC power supply has been widely used in computer, communication, railway, aerospace, household appliances and other fields. In order to improve the stability and reliability of power supply products, manufacturers at home and abroad generally adopt the resistance energy consumption method to carry out aging tests on small and medium power supplies. China is the world's largest manufacturer of small and medium power power supply products. Traditional aging test methods cause huge waste of energy and poor adaptability to products of various capacity levels. Therefore, research on more economical and adaptable energy-saving aging test systems is of great importance. Very important. [0003] However, there are still a lot of probl...

Problems solved by technology

China is the world's largest manufacturer of small and medium power power supply products. Traditional aging test methods cause huge waste of energy and poor adaptability to products of various capacity levels. Therefore, research on more economical and adaptable energy-saving aging test systems is of great importance. very important

[0003] However, there are still a lot of problems in the aging of small and medium power DC power supplies. Among them, the aging energy of small and medium power DC power supplies is scattered, and it is difficult to achieve cost-effective energy feedback. Traditional aging cabinets use resistors as loads, which generate a lot of heat consumption during the aging process, resulting in energy waste. , and need timely heat dissipation
