The testing chamber is mainly composed of a testing chamber body, an insulation layer and a door for forming an enclosed space. One side inside the enclosed space is provided with at least one heating channel; one side of the heating channel is provided with at least a refrigeration channel; and a testing area is formed among a channel separation plate, an air inlet baffle plate, an air outlet baffle plate, the chamber body and the door.
Description
Technical field
The utility model relates to a kind of environmental test equipment field, relates in particular to the chamber that a kind of heat tunnel and refrigerating channel share blower motor.
Background technology
Chamber is typically designed to the form of heating and the shared passage of refrigeration, and the dividing plate between pilot region and passage is simple steel plate isolation, although such design is simple, but because the evaporator duty factor is larger, need the outer evaporator load of commitment during well heater work, so not energy-conservation; Simultaneously, because there is no the thermal insulation board isolation between pilot region and passage, and there is temperature difference between pilot region and passage, so the homogeneity in the temperature field of the pilot region of close channel partition is not very desirable; Secondly, chamber does not arrange Motorized Operated Damper usually between passage and pilot region yet, during humid test, often needs to adopt cold thermally equilibrated control mode, causes equipment power consumption, the lost of life; In addition, chamber usually, also not in passage and pilot region setting and the extraneous Motorized Operated Damper communicated, causes the constant of hot stage or cooling to need to start refrigeration unit, thereby causes equipment power consumption on the one hand, also accelerate on the other hand the aging of cold-producing medium, shortened the life-span of equipment.
For not needing the fast-changing chamber of temperature, the problems referred to above show to such an extent that be not very serious, but in the chamber that needs fast temperature to change, because evaporator area designs greatlyr, in the warm process that raise fast by low temperature that does not need refrigeration, the evaporator load is exactly a very large extra load for well heater, when can causing design, this need to consider extra evaporator load, thereby need to design greatlyr by heater power, cause the significantly increase of chamber power and manufacturing cost, use cost; Simultaneously, in the process that is rapidly heated or lowers the temperature, the temperature difference of passage and pilot region is very large, if there is no the thermal insulation board isolation, the temperature of the pilot region of close channel partition can be low or high more a lot of than the temperature of other pilot region, cause the temperature field of pilot region very inhomogeneous.

Embodiment
Illustrate that by Fig. 1 an embodiment of the present utility model is as follows.
With reference now to accompanying drawing 1, describe embodiment of the present utility model, in accompanying drawing, identical element numbers represents similar element.As mentioned above, as shown in Figure 1, the heat tunnel that the utility model provides and refrigerating channel share the chamber 50 of blower motor, and it comprises:
As shown in Figure 1, chamber mainly consists of the space of a sealing the test chamber door of testing casing 10, heat-insulation layer 10a and do not indicate in the drawings.
Heat tunnel one side is equipped with independently refrigerating channel 20c, and is positioned at fan 19 air inlet one sides; Refrigerating channel mainly is comprised of refrigerating channel casing 13, heat-insulation layer 10a, channel partition 14, Motorized Operated Damper 11b and 11c.
Refrigerating channel 20c inside at least is equipped with one group of evaporator 12.
Air outlet baffle plate 22 air outlet places at least are equipped with one group of temperature sensor.
Chamber do normal temperature, high temperature constant, heat up or while from high temperature, reducing the hot stage of temperature test, refrigerating channel does not participate in test, Motorized Operated Damper 11b, 11c are in closed condition; Heat tunnel participates in test, and Motorized Operated Damper 11d is in open mode.18 runnings of controller drive drum wind turbine, blower motor 18 drives fan 19 and rotates, fan 19 drives the gas in heat tunnel 20b to move toward pilot region 20a, cause thus the malleation of heat tunnel 20b internal fan 19 air outlet one sides and the negative pressure of air inlet one side, under the acting in conjunction of fan 19 air outlet one side malleations and air inlet one side negative pressure, the air vent of gas on air inlet baffle plate 21 in pilot region 20a, Motorized Operated Damper 11d flows into heat tunnel 20b, and after heater via 15 pre-service, air vent under the driving of fan 19 from air outlet baffle plate 22 is discharged, enter pilot region 20a, the temperature of adjusting test zone 20a, finally be back to the bottom of pilot region 20a, again by the air vent on air inlet baffle plate 21, Motorized Operated Damper 11d enters heat tunnel 20b, enter next gas processing circulation.The gas processing circulation is a continuous process.The temperature value that the temperature that controller is set according to chamber and pilot region 20a temperature sensor detect, carry out the PID adjusting to adding heat as required, the aperture of regulating as required Motorized Operated Damper 11a, 11e simultaneously, thereby realize the even, stable of pilot region 20a temperature field, and reach effect energy-conservation, the extension device life-span.When the low thermophase that low temperature is constant or high temperature reduction temperature is tested is done in chamber, well heater 15 does not participate in test, and Motorized Operated Damper 11a, 11d, 11e are in closed condition, refrigerating channel participates in test, and Motorized Operated Damper 11b, 11c are in open mode, 18 runnings of controller drive drum wind turbine, blower motor 18 drives fan 19 and rotates, fan 19 drives the gas in heat tunnel 20b to move toward pilot region 20a, cause thus the malleation of heat tunnel 20b internal fan 19 air outlet one sides and the negative pressure of air inlet one side, under the acting in conjunction of fan 19 air outlet one side malleations and air inlet one side negative pressure, the air vent of gas on air inlet baffle plate 21 in case, Motorized Operated Damper 11c flows into refrigerating channel 20c, and after evaporator 12 pre-service, enter heat tunnel 20b by Motorized Operated Damper 11b, air vent under the driving of fan 19 from air outlet baffle plate 22 is discharged, enter pilot region 20a, the temperature of adjusting test zone 20a, finally be back to the bottom of pilot region 20a, again by the air vent on air inlet baffle plate 21, Motorized Operated Damper 11c enters refrigerating channel 20c, enter next gas processing circulation.The gas processing circulation is a continuous process.The temperature value that the temperature that controller is set according to chamber and pilot region 20a temperature sensor detect, carry out the PID adjusting to refrigerating capacity as required, thereby realize the even, stable of pilot region 20a temperature field.
When chamber is done high temperature or is rapidly heated test, if the case internal pressure is higher than external atmospheric pressure, by air-pressure balancing device 17 pressure releases, until the case external and internal pressure reaches equilibrium state.
When the test of low temperature or fast cooling is done in chamber, if the case internal pressure lower than external atmospheric pressure, ambient atmosphere enters in case by air-pressure balancing device 17, until the case external and internal pressure reaches equilibrium state.
The heat tunnel that the utility model provides and refrigerating channel share the chamber 50 of blower motor, because intensification, cooling, constant temperature test have all been realized the automatic adjusting of controller, so, as long as will need the setting parameter of test good in use, chamber just can move by the parameter set, thereby realizes intelligentized control.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belong to the scope that the utility model is contained.
