On described cabinet two side plates respectively corresponding first cavity and the second cavity respectively arrange one with the ventilating opening of ft connection, this ventilating opening is respectively exhaust outlet and air inlet, and exhaust outlet and air inlet are closed by solenoid valve and opened;
Fibre optic temperature sensor is provided with in described first cavity and the second cavity; All fibre optic temperature sensors are connected in fiber optic splitter, and all fiber optic splitter are connected on optical Fiber Closure, and described optical Fiber Closure control linkage is on light analyser; Also comprise controller, controller connects light analyser simultaneously, display device and warning device.
Further: above-mentioned heat pump comprises compressor, and compressor connects indoor heat exchanger successively by refrigerant pipe, throttling valve, outdoor heat exchanger, gas-liquid separator, final refrigerant tubing takes back to compressor formation circulation.
Further: above-mentioned outdoor heat exchanger place is provided with radiator fan; The refrigerant tubing of described compressor is also serially connected with four-way valve; Described controller is heat pump described in control linkage also, circulating fan, the solenoid valve at fibre optic temperature sensor and ventilating opening place.
The proving installation of a kind of LED drive power described in the utility model, it has the following advantages:
1, the utility model is evenly arranged in cabinet inside the Real-time Collection that fibre optic temperature sensor carries out cabinet internal temperature information simultaneously; Fibre optic temperature sensor the most at last temperature information is passed to light analyser and carries out analytical calculation, finally carries out centralized control by controller; After real-time monitoring temperature information, controller can take the control mode such as display and warning in real time, avoids the change of cabinet internal temperature and causes tested product to lose efficacy; Simultaneously owing to have employed optical fiber temperature measurement system, considerably increase measuring accuracy and the control accuracy of temperature;
2, the utility model adopts heat pump to add hot-air as thermal source, therefore possesses energy-saving; Meanwhile, owing to being equipped with four-way valve in heat pump, once need to reduce cabinet internal temperature fast, the refrigeration mode of heat pump can also be adopted freeze; Certainly, in most cases, only need to open exhaust outlet and air inlet and door-plate and can reach requirement to carry out cooling;
3, the air channel heating of hot blast of the present utility model in top board, move downwardly to gap location via the first cavity, hot blast enters the second cavity, is finally back to air channel continuous heating by the return air inlet of the second cavity, forms circulation; Therefore hot blast of the present utility model is a large circulation, can ensure that the temperature of cabinet inside is more even; Meanwhile, the utility model two cavitys can be regarded as two independent aging spaces, because ageing rack pros and cons has all hung LED drive power, therefore, it is possible to measure more power supply simultaneously.
