Description
Technical Field
The utility model relates to an ultrasonic humidifying system of a temperature test chamber, which is mainly suitable for a high-low temperature damp-heat test chamber and a humidity test chamber and provides humidity for a test environment.
Background
With the rapid development of the industries of aerospace, electronics, communication, automobiles and the like, more rigorous requirements are provided for performance indexes of products and key parts. Related standards such as industry standards, national standards, American standards, daily standards and the like are successively provided, and reliability of products is detected.
The high-low temperature environment test chamber with humidity and the humidity test chamber with humidity are generally applied to various industries, but the traditional mode of steam humidification cannot meet the requirements of practical use, particularly the on-load test of products, and when a sample generates heat, the heat generated by steam humidification and the sample are superposed to cause temperature runaway and cannot be stabilized at the required temperature. In order to realize the stability of the temperature, the refrigerating capacity must be increased, but the humidity can be reduced while the refrigerating capacity is increased, at the moment, the humidity is reduced, the heating power of the steam needs to be correspondingly increased to meet the humidity requirement, an optimal balance point is difficult to achieve, the steam cannot be well matched, the power of the equipment is greatly increased, and the energy consumption of the equipment is greatly increased. Steam humidification tests at low and high temperatures and high humidity are difficult to achieve when the sample has a heat load.
SUMMERY OF THE UTILITY MODEL
The utility model provides an ultrasonic humidifying system of a temperature test box, which can overcome the defects.
The purpose of the utility model is realized as follows:
the utility model provides a temperature test case ultrasonic wave humidification system, it includes the humidifier box, is equipped with water in the humidifier box, and the ultrasonic atomization ware is installed to the bottom of humidifier box, liquid level switch and filler are equipped with to the side of humidifier box, liquid level switch, filler all link to each other with control system, the compressed air mouth has been seted up at the top of humidifier box, and compressed air pours into the humidifier box into through the compressed air mouth, the humidification mouth is seted up at humidifier box top, the other end of humidification mouth is linked together with the air inlet of test box, and the fog that the ultrasonic atomization ware produced is being blown by compressed air, enters into in the test box from the humidification mouth.
Preferably, when the water level is lower than a set value, the control system controls to open the water filling port and add water into the humidifier tank.
Preferably, the top of the inner wall of the humidifier box body is provided with a guide plate.
The ultrasonic humidifying system of the temperature test chamber has the advantages that:
this kind of temperature test case ultrasonic wave humidification system utilizes ultrasonic atomizer to produce humid air and adds to the test box internal, because the humid air that adds is normal atmospheric temperature, can play the effect of cooling in the humidification, can effectually offset the load that generates heat of part test piece, is favorable to doing high temperature and high humidity and low temperature and high humidity test.
And it also has the following advantages:
1. the temperature test box ultrasonic humidifying system is small in size, simple in structure and low in manufacturing cost.
2. The compressed air is used to generate air flow, so that the change of air pressure in the box and the back overflow of cold and hot air flow can be effectively prevented when humidification is not performed.
3. The compressed air is generally subjected to water removal and cooling, the temperature is lower than the normal temperature, and the heat productivity of the sample can be more effectively counteracted when the wet air enters the test box body.
4. The guide plate is arranged, so that the mist generated by the ultrasonic small atomizer can be more efficiently conveyed into the test box body.
5. May be used independently or in conjunction with a vapor humidifier. Meeting more demanding requirements.
6. The transported normal temperature and humidity air can effectively offset and relieve the heat productivity of the sample, and meanwhile, the humidifying function is more suitable for realizing the test requirements of low temperature and high humidity or high temperature and high humidity.
7. The power is very small, the humidification quantity is large, the energy consumption is below 1/10 of the original humidification system, and the emission reduction is realized.
8. The ultrasonic small atomizer is a standard part, so that the purchasing cost is low and the maintenance is convenient.
