Described ultrasonic wave refrigerating humidifying device 8 also comprises: pressue device 82, and described pressue device 82 is located on described conveyance conduit 83 and is pressurizeed to the water on described conveyance conduit 83.
Four subtubes that described conveyance conduit 83 also comprises main pipeline 831 and is communicated with described main pipeline 831, described subtube is in being laid on described main pipeline 831 side by side, and flow sensor 833 and magnetic valve 834 is provided with on each described subtube, and described flow sensor 833 and magnetic valve 834 are all connected with controller (figure does not show), described controller detects the flow information on described subtube by described flow sensor 833, and is controlled the current size on described subtube by described magnetic valve 834.The temperature sensor be connected with described controller also must be provided with in described internal box 3, for detecting the temperature in described internal box 3 at any time, described magnetic valve 834 has to be increased/reduces/be closed in the function of the discharge size on described subtube, and described magnetic valve 834 can control discharge and temperature.
In addition, described internal box 3 installs humidity sensor, and it is connected with described controller, controls in real time the humidity environment in described internal box 3, by increasing/reducing the power of described ultrasonic wave refrigerating humidifying device 8, and then the humidity size increasing or reduce in described internal box 3.
Described main pipeline 831 is firm metal material, and it is hollow structure, and inner formation current circulation passage, described main pipeline 831 is connected with for hanging testee 50, horizontally disposed crossbeam 835.
Described main pipeline 831 is also provided with relief valve.
Because described ultrasonic water mist generator 82 excites generation ultrasonic-wave water-atomization to the water in described tank 88, steam can provide the humidity environment of test on the one hand, the heat that testee 50 produces can also be lowered the temperature in addition, therefore be extremely applicable to testing measured object under hot and humid environment, lasting generation water smoke then can make the discharge reduction in described conveyance conduit 83 and described tank 88, must guarantee that the water yield is in the scope be applicable to, or can add water from outside.
Described air-out passage 31 is defined by inwall on perforate sheet material 9 as shown in Figure 5 and described internal box 3 to form, and described return air channel 32 is formed for being defined by described perforate sheet material 9 and described internal box 3 times inwalls.
Described crossbeam 835 is also provided with clamping device (figure does not show), testee 50 is held on described clamping device.
Be provided with the first track 34 bottom described internal box 3, the lower end of described main pipeline 831 be fixedly connected with described first track with the use of slide block 35, described main pipeline 831 advances or releases described internal box 3 by described slide block 35.
Described moisture-heat test-box 100 also includes a matching board (figure does not show), roller is provided with bottom described matching board, described matching board is placed on the ground in chamber front, with described internal box 3 times inwall levels, also be provided with second track (figure does not show) that can dock with described first track 34, described main pipeline 831 can enter or release described internal box 3 from described matching board.By described matching board, can be easy to low testee 50 loading or unloading to be got off,
Composition graphs 1-5, operationally, described controller control blower fan 73 operates moisture-heat test-box of the present invention on the one hand, and blower fan 73 driving gas forms circulating current between described air-out passage 31, return air channel 32 and trial zone 33.Gas in described side box body 4 is toward the lateral movement of described air-out passage 31 1, cause the malleation of the air outlet side of described blower fan 73 in described side box body 4 and the negative pressure of air inlet side thus, under the acting in conjunction of described blower fan 73 air outlet side malleation and air inlet side negative pressure, in described internal box 3, gas flows into described side box body 4 through described return air channel 32, described internal box 3 is flowed into again inner by described air-out passage 31, and be provided with described treating apparatus 7 in described side box body 4, described treating apparatus 7 comprises described heater 71 and the first refrigerating plant 72, can control the temperature of air-flow, generally, what described heater 71 and described first refrigerating plant 72 can realize carries out control effects to temperature is limited, the test request of the larger testee of caloric value 50 under hot and humid condition can't be met, unless that chamber is done is enough large, and control the quantity of testee 50, guarantee enough heat-dissipating spaces, it is enough large that described internal box 3 does by needs, so just need higher cost, the heat absorption that but if testee 50 can be sent, then can test in the chamber of existing size, and need not the volume of lifting test case, therefore, add described ultrasonic wave refrigerating humidifying device 8, it comprises: the second refrigerating plant 81, ultrasonic water mist generator 82 and conveyance conduit 83, it not only can be provided for for described internal box 3 inside the low-temperature receiver absorbing testee 50 evolution of heat, and test humidity environment can be provided, kill two birds with one stone.
