Dry constant temperature test chamber

Abstract

The invention relates to a laboratorial culture tank and discloses a drying constant-temperature test box. The drying constant-temperature test box comprises an insulating layer, a constant-temperature air circulating device and a front door, wherein the insulating layer and the front door form a closed constant-temperature inner cavity; the constant-temperature air circulating device comprises a motor, a wind wheel and a circulating air duct; the motor drives the wind wheel to rotate, the circulating air duct comprises an air exhausting duct and an air inlet duct, one end of the air exhausting duct is connected with an air outlet of the wind wheel, the other end of the air exhausting duct is communicated with the constant-temperature inner cavity, the air exhausting duct comprises an air duct cover plate arranged above the wind wheel, one or more exhausting holes are formed in the air duct cover plate, an air velocity sensor is arranged between the air duct cover plate and a draught fan, a heating device is arranged on the inner side, close to the air inlet duct, of a first exhausting hole, and a temperature sensor is arranged between the first exhausting hole and the heating device. The drying constant-temperature test box has the advantages that stable hot air circulation can be realized in the constant-temperature inner cavity, and the test box can be uniformly heated, is good in temperature control effect and high in precision and has a high application value.

Description

technical field

[0001] The invention relates to a laboratory incubator, in particular to a dry constant temperature test box. Background technique

[0002] The electric constant temperature incubator is suitable for scientific research and industrial production departments such as medical and health, pharmaceutical industry, biochemistry and agricultural science, and is widely used in the constant temperature test of bacterial culture, fermentation and constant electric heating constant temperature incubator. The feature of this product is constant temperature heating. In the prior art, there are many similar devices, but as far as the laboratory is concerned, some experiments require a high constant temperature control rate, and the existing devices often only have highly sensitive temperature sensors. , trying to use high-precision temperature control to achieve a higher level of constant temperature control. However, experiments have found that the temperature fluctuatio...

Examples

Embodiment 1

[0029] Dry constant temperature test chamber, such as Figure 1-5 As shown, including the insulation layer 1, the constant temperature air circulation device 2, and the front door 3, the insulation layer 1 and the front door 3 form a closed constant temperature inner chamber 4. In order to improve the strength of the constant temperature inner cavity 4, the upper, lower, left, and right side walls of the constant temperature inner cavity 4 (wherein the inner side wall refers to the side wall relative to the front door 3, and the upper and lower side walls refer to the side wall relative to the front door 3). The side walls on both sides in the vertical direction, the left and right side walls refer to the side walls on both sides in the horizontal direction relative to the front door 3) respectively covered with metal plates 41, which can usually be made of materials such as copper, aluminum alloy, steel, etc. , the junction of the right and inner side walls and the lower side...
