Summary of the invention
In order to overcome the deficiency that cooling effect is relatively poor, measured power is limited of existing microwave tube device test system, the utility model provides a kind of platinotron device test system that promotes cooling effect, improves measured power.
The utility model solves the technical scheme that its technical matters adopted:
A kind of platinotron device test system; Comprise driving box, ageing oven and water-cooling system, said driving box comprises control panel, accessory power supply and aging power supply, and said accessory power supply all is connected with said control panel with aging power supply; Said ageing oven comprises a plurality of test station platforms; Each test station comprises high-power heating radiator and test fixture, and said test fixture is connected with said aging power supply, and the cooling water pipe of said heating radiator is communicated with said water-cooling system.
Further, be provided with in the said test fixture in order to fix the elastic fixing device of platinotron to be tested.
Further again, the inboard microwave absorbing material layer that attaches of said test fixture.
Further, said test fixture is the full-shield enclosed construction, and the inlet wire side of said test fixture is installed feedthrough capacitor.
The beneficial effect of the utility model mainly shows: promote cooling effect, improve measured power.
Description of drawings
Fig. 1 is the structural drawing of platinotron device test system.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, a kind of platinotron device test system comprises driving box 2, ageing oven 1 and water-cooling system 3; Said driving box 2 comprises control panel, accessory power supply and aging power supply; Said accessory power supply all is connected with said control panel with aging power supply, and said ageing oven comprises a plurality of test station platforms, and each test station comprises high-power heating radiator and test fixture; Said test fixture is connected with said aging power supply, and the cooling water pipe of said heating radiator is communicated with said water-cooling system 3.
Be provided with elastic fixing device in the said test fixture in order to fixing platinotron to be tested.The inboard microwave absorbing material layer that attaches of said test fixture.Said test fixture is the full-shield enclosed construction, and the inlet wire side of said test fixture is installed feedthrough capacitor.
In the present embodiment, the station test platform: 24 tests of every complete equipment station, the copper heat transfer test platform of each cell configuration one cover cooling guarantees the heat radiation requirement of device when high-power test.The water cooling test platform except that with the direct contact portion of device, remainder all should be incubated, heat insulation.High-power water-cooling system (refrigerating capacity of >=10kW); Water-cooling system is made up of water tank, evaporator, water pipe and refrigeration machine.Ageing oven is connected with driving box through connecting lead.Ageing oven links to each other with water-cooling system through water pipe.
System can be suitable for that the HIGH-POWERED MICROWAVES transistor is carried out stable state rated power (peak power is 350W) and wear out.Provide microwave tube (the hermetically sealed encapsulation of metallic ceramics) full-shield sealing unique heat radiation test fixture, through powerful water cooling system, the temperature that makes the device package bottom surface 40 degree or below.System test circuit and test fixture have adopted anti-vibration and anti-microwave radiation technology.Circuit design should take into full account to microwave device the higher-order of oscillation that produces when aging and shield absorption, makes its influence to surrounding devices and people be reduced to minimum.Anchor clamps adopt the full-shield sealing, and inlet wire adopts feedthrough capacitor, prevents that microwave from spreading out of through lead electrode.Through microwave absorbing material (ferrite and rubber) is affixed on the metal fixture inboard, can absorb the microwave that reflects back.Can adopt in the circuit and move back the lotus root circuit design that clutter attenuation is arrived is minimum.The clamp structure design has certain snap-in force when aging device is installed, and guarantees electricity and thermo-contact that device and platform are good.
Adopt the novel high-power water-cooling system, maximum refrigeration work consumption 10KW, heat-conduction medium adopts aqueous water, and for preventing to get rusty and fouling, water tank, water pump, pipeline all adopt stainless steel and engineering plastics to make, and water is with pure water (deionized water), and regularly cleaned and changed.Water delivering orifice has stainless steel filter.24 tests of every complete equipment station, the copper heat transfer test platform of each cell configuration one cover cooling guarantees the heat radiation requirement of device when high-power test.The water cooling test platform except that with the direct contact portion of device, remainder all should be incubated, heat insulation.
The every station of the utility model provides one to overlap independently aging platform; Every cover aging platform comprises high-power heating radiator and hermetic metallic cavity (inside comprises the flexible type stationary installation of test fixture, microwave absorbing circuit elements device, temperature sensor, device etc.); On each anchor clamps (in shell lower curtate or shell base one side; Can select by the user) temperature probe is provided, shell temperature that can the testing experiment device; Make the temperature of shell bottom surface under 30 ℃ of environment temperatures, the full power test condition be not more than 40 degree.
The utility model heat radiation test platform adopts closed high-low temperature resistant material and processing technology, the seepage phenomenon when avoiding long-play.And what refrigeration system taked that circuit and water route separate designs, and guarantees normal operation circuit.Aspects such as water cooling system relates to temperature alarming protection, cuts off the water supply/the lack of water alarm and protection, antiseep, water pump protection, compressor protection adopt reliability design, and water cooling system is monitored in real time, guarantee the practicality of water cooling system, reliable and safety.Thereby reduction maintenance cost.
The effect that the utility model is useful mainly shows: can reduce the heat that produces on the device to greatest extent, through chilled water heat taken away, thereby make device shell temperature drop low.Through aging platform being added metallic seal radome and the technical design that absorbs circuit, microwave tube self-sustained oscillation is effectively suppressed.
