Description

The utility model relates to techniques for climate testing of various, in particular radio engineering products.

A device is known for testing samples for heat resistance, comprising means for attaching samples, a heating and cooling chamber with a relative displacement drive and instrumentation, the cooling chamber made in the form of a cup installed in the heating chamber, with holes made in its side wall and walls camera channels. The drive for moving the cooling chamber is made in the form of means for supplying a cooling medium under pressure to the end of the cup.

The disadvantage of such a test chamber is only the sequential effect of either heat or cold, and the dimensions of the test objects are limited by the dimensions of the transport glass.

Also known is a device for testing products for thermal shock, comprising a heat chamber and a cold chamber separating their heat-insulating wall with an opening, a container for placing products installed in the wall opening with the possibility of movement, a sealing system and a movement mechanism, while the sealing system is made in the form of heat-insulating plugs fixed at the ends of the container and the thickness of which is equal to the thickness of the insulating wall.

(SU 700820, A1 5 G01N 3/60, 1979.11.30)

The disadvantage of this climate chamber is only the sequential testing of heat and cold, the lack of the possibility of simultaneous climate tests of heat and cold. The size of the test product is limited by the size of the container to accommodate the test product.

The closest is a chamber containing a housing in which the sensors of the parameters of the test object are located, a cooling system, a heating system, a fan and a door for loading the test object. The outputs of the sensors of the parameters of the test object are connected to the inputs of the control unit, the outputs of which are connected to the control inputs of the cooling system, heating system and fan. The camera body is divided into two sections by a heat-reflecting insulating partition with the possibility of moving inside the camera, containing a window larger in size than the side of the test object, and having detachable seals around the perimeter between the partition and the camera body and between the partition and the test object. The test chamber also contains a second heating system, a cooling system, a fan and parameters sensors of the test object, while the outputs of the sensors of the parameters of the tested object are connected to the inputs of the control unit, the outputs of which are connected to the control inputs of the second cooling system, heating system and fan. (RU 2399903, G01M 19/00, G01N 25/00, 2009.06.15)

The disadvantage of this climate chamber is that the window in the partition is made to fit the dimensions of the test product. When testing a different sized test product, a different partition with a window of a different size is needed.

The technical result of the utility model consists in the possibility of carrying out climate tests simultaneously with heat and cold, using the same heat-reflecting heat-insulating partitions for testing test objects of various sizes.

To achieve the technical result, a test chamber is proposed, comprising a housing in which there are two sets of sensors of the parameters of the test object, a door for loading the test object, two cooling systems, two heating systems and two fans. In each section, the outputs of the sensors of the parameters of the test object are connected to the inputs of the control unit, the corresponding outputs of which are connected to the control inputs of the cooling system, heating system and fans located in different sections, while the interior of the chamber is divided into two sections by a heat-reflecting heat-insulating partition with the possibility of movement inside cameras. The partition consists of one or more parts, depending on the design of the test object. To form a window in the partition, those parts of the partition that are closest to the seal with the test object are removable and of different sizes. If the dimensions of the test object are larger, then removable partitions of the smaller partition are used and vice versa. Detachable seals are installed between the test object and the partition and between the partition and the camera body. For ease of movement and ensuring structural rigidity, the partition is enclosed in a frame. The assembly of the partition is carried out as follows: large parts of the partition are installed in the frame, then the removable part of the partition is installed, and then the detachable seals are installed between the test object and the partition and between the partition and the camera body.

The test object 8 is installed in the camera. In the frame 10, one or more parts of the partition 11 are installed depending on the design of the test object. The partition 9 is moved to the test object so that one side of the test object fits into the window 14 in the partition. The removable partitions 11 of the partition are installed in the gap between the test object and the partition. If the dimensions of the test object are larger, then removable partitions of the smaller partition are used and vice versa.
