Temperature adjusting system of integrated sand-blowing dust-blowing environment simulation system and method thereof

Abstract

The invention discloses a temperature adjusting system of an integrated sand-blowing dust-blowing environment simulation system, comprising a heat exchanger, an electric heater and a cooling medium and heating medium unified allocation network, wherein the each passage is provided with a plurality of valves for controlling flow rate. A heat-transmitting part and a temperature-adjusting part, the separating part and the flow guide part of a sand-blowing wind hole and a dust-blowing wind hole, and hole body structures are combined together, therefore, the system has compact structure and convenient clearance, is an integrated sand and dust environment test device with fast temperature adjustment and continues work capability, has less occupied space, good airflow quality of a test section and low system energy consumption, and is especially suitable for the occasion of continues test.

Description

Technical field: [0001] The invention relates to a temperature adjustment system and method of an integrated sand blowing dust blowing environment simulation system. Background technique: [0002] Sand and dust environment is an important environmental factor that causes the failure of many engineering and / or military weapons and equipment. The main damage types are: erosion, wear, corrosion and penetration. Dust blowing and sand blowing tests are important means to test the environmental adaptability and environmental reliability of vehicles, aircraft, electrical equipment, and military equipment in deserts, arid areas, and sandy weather conditions. [0003] The existing sand blowing dust blowing environment / simulation test device system uses two air-conditioning boxes, one large and one small, to complete the temperature control. Such as figure 1 As shown, the Chinese patent ZL200510000070.8 discloses a system, wherein, the label 1 is a circulating air duct, 2 is a large...

AI Technical Summary

Problems solved by technology

[0004] - Due to the use of two air conditioners, air conditioner 2 and air conditioner 3, to control the temperature of the wind tunnel, the structure of the system is complicated and takes up a lot of space. The large air conditioner intake channel 7, the small air conditioner intake channel 8 and the air conditioner return air channel 9 are all directly communicated with the circulating air duct 1, and these passages 7 and 8 affect the quality of the airflow in the air duct 1;

[0005] - In order to control the temperature, the air conditioner 2 and the air conditioner 3 respectively use circulating cooling water and chilled water from the chiller 10 as the cooling medium, and the small air conditioning box is also equipped with an electric heater 5 and a variable frequency speed regulating fan 6, They work together to complete the temperature adjustment
