Embodiment Construction
[0039] The technical solution of the present invention is described below by specific embodiments in conjunction with the accompanying drawings:
[0040] see Figure 1 to Figure 5 , an extreme high and low temperature environment test shelter of the present invention includes a box body 100, a fuel heater 12, an electric control cabinet 8, an air duct system, a refrigeration unit, a hot and cold air circulation system and a control system.
[0041] The box body 100 is container-type, which saves the expensive cost of building a laboratory and land occupation, and can realize rapid movement and open-air parking, which greatly facilitates the use of users; the box body 1 passes through the left and right partitions from left to right. The plates 31 , 32 are divided into the operating chamber 10 , the middle compartment 17 and the testing chamber 15 . The inner wall of the box body 100 is also covered with an insulating layer, which is rigid polyurethane foam plus a small amount...

The invention discloses a test cabin for extreme high and low-temperature environments. The test cabin comprises a container type box, a fuel oil heater, an electric control cabinet, an air channel system, a refrigerating unit, a cold and hot air circulating system and a control system, wherein the box is partitioned into an operation chamber, a compartment and a test chamber; the electric control cabinet and the fuel oil heater are arranged in the operation chamber; an evaporator of the refrigerating unit is arranged in the compartment; a unit to be tested is arranged in the test chamber; the upper parts of the front and back side faces of the test chamber are provided with a test chamber air inlet respectively; the front side face of the test chamber is provided with a test chamber shutter; the air channel system comprises two air suction channels, two hot air channels and an internal chamber air channel; one end of each air suction channel is connected with the air inlet of the air suction channel, and the other end of each air suction channel is connected with the air inlet of the fuel oil heater; the air inlets of the two hot air channels are connected with the hot air outlet of the fuel oil heater; the hot air channel passes through the compartment and is communicated with the test chamber; and one end of the internal chamber air channel is connected with the air inlet of the internal chamber air channel, and the other end of the internal chamber air channel is positioned in the test chamber, so that air stream in the compartment is communicated with air stream of the test chamber.
Description
technical field [0001] The invention relates to an environmental test equipment, in particular to an extreme high and low temperature environmental test shelter, which is used for extreme high and low temperature environmental tests on small diesel generator sets and silent generator sets. Background technique [0002] Generator sets are widely used as independent power sources for special purposes such as telecommunications, financial departments, hospitals, schools, commercial departments, and industrial and mining enterprises. After the generator set is manufactured, a series of tests must be carried out, the most important of which is to conduct a comprehensive performance test in an environment of extreme high and low temperature. At present, in the generator set manufacturing industry, there is no standard environmental laboratory that can conduct comprehensive performance tests on the entire set of generator sets and silent units under simulated extreme high and low t...
