Abstract
The invention discloses a constant temperature and humidity tester, which comprises a box, wherein a test area, an evaporator and a fan are arranged in the box; the evaporator and the fan are arranged at one side of the test area; a top air-guide plate and a bottom air-return plate are arranged in the test area in parallel; upright lateral plates are connected to the side parts of the top air-guide plate and the bottom air-return plate; air channels are arranged on the peripheries of the top air-guide plate and the bottom air-return plate and the four walls of the test area; the air channel is also arranged at the joint between the lateral plate and the bottom air-return plate; the bottom air-return plate is provided with a plurality of air-return holes; and the air-return holes are all arranged on the edge of the bottom air-return plate. The top air-guide plate and the bottom air-return plate are arranged in the test area, so after the airflow enters into the test area, the strong air-inducing backflow is formed around the air-return holes, thereby homogenizing the test temperature and humidity in the test area, eliminating all the dead angles and greatly enhancing the practicability.
Description
Technical field
The present invention relates to a kind of testing equipment, be specifically related to the constant temperature and moisture test machine.
Background technology
The constant temperature and moisture test machine is mainly used in testing the control of environment of living in, to satisfy special requirement to temperature, humidity, that guarantees to test carries out and Related product quality stable smoothly, and for example analog equipment carries out high low-temperature operation under the warm and humid combination condition of climatic environment; Storage, temperature cycles, hot and humid, low temperature and low humidity, condensation test or the like, whether the adaptive faculty of testing product itself and characteristic change.Existing constant temperature and moisture test machine, mainly comprise the measuring tank body, be positioned at test section, evaporator and the blower fan of casing, produce the humiture circulation in the test section, provide test required environmental parameter, find in actual the use that the junction of adjacent two walls in test section forms the dead angle easily, water vapor is assembled after near the condensation dead angle, test is exerted an influence, cause experimental result quite different, practicality has much room for improvement.
Summary of the invention
The purpose of this invention is to provide the constant temperature and moisture test machine that a kind of practicality is improved.
The technical solution adopted for the present invention to solve the technical problems is: the constant temperature and moisture test machine, comprise casing, the evaporator and the blower fan that are provided with the test section in the casing and are positioned at test section one side, be arranged with top wind deflector and bottom return air plate in the described test section in parallel, top wind deflector and bottom return air plate sidepiece are connected with vertical side plates, top wind deflector and bottom return air plate periphery and test section wall are equipped with the air channel, the junction of side plate and bottom return air plate offers the air channel, offers some return air holes on the return air plate of bottom.
Described return air hole is distributed in return air panel edges place, bottom.
The invention has the beneficial effects as follows: be provided with top wind deflector and bottom return air plate in the casing, after air-flow enters the test section, a part flows through the air channel between top wind deflector and bottom return air plate and test section wall, a part flows through the air channel between side plate and the bottom return air plate, and a part flows through return air hole, forms strong air draught and reflux around return air hole, make the homogenising of test section build-in test temperature and humidity, do not stay the dead angle, therefore can not exert an influence to test, practicality strengthens greatly.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
With reference to shown in Figure 1, the constant temperature and moisture test machine, comprise casing 1, the evaporator 3 and the blower fan 4 that are provided with test section 2 in the casing 1 and are positioned at 2 right sides, test section, be arranged with top wind deflector 5 and bottom return air plate 6 in the described test section 2 in parallel, top wind deflector 5 and return air plate 6 right sides, bottom are connected with vertical side plates 7, top wind deflector 5 and bottom return air plate 6 peripheries and test section 2 walls are equipped with the air channel, side plate 7 offers the air channel with the junction of bottom return air plate 6, offer some return air holes on the bottom return air plate 6, described return air hole is distributed in bottom return air plate 6 edges.After air-flow enters test section 2, a part flows through the air channel between top wind deflector 5 and bottom return air plate 6 and test section wall, a part flows through the air channel between side plate 7 and the bottom return air plate 6, a part flows through return air hole, around return air hole, reach strong air draught and reflux, make the homogenising of test section build-in test temperature and humidity, do not stay the dead angle, therefore can not exert an influence to test, practicality strengthens greatly.
The foregoing description is illustrative principle of the present invention and effect thereof only; and the embodiment of part utilization, for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; can also make some distortion and improvement, these all belong to protection scope of the present invention.
