Embodiment 1

[0021] a kind of like figure 1 The damp heat equipment for fast and uniform temperature and humidity shown includes a main box body 1, an auxiliary box body 5, and an electrical system box. Wherein the main box body 1 has a sample placement chamber 2, and a shelf can be arranged in the sample placement chamber for placing samples to be tested. A front door 11 is provided at the front of the main box body 1 for opening and placing samples in the sample placement cavity 2 .

[0022] An air inlet pipe 9 is arranged on one side of the upper part of the sample placement chamber 2 , and a built-in blower 8 is arranged in the air inlet pipe 9 for sending wind into the sample placement chamber 2 . The air inlet end of the air inlet pipe 9 is connected with a humidification system 10, a refrigeration system 6, and a heating system 7 for controlling the temperature and humidity of the incoming air. The outlet end of the air inlet pipe 9 is inclined to the top surface of the sample pla...

Embodiment 2

[0025] like figure 2 As shown, the rest of the structure is the same as that of Embodiment 1, and its distinguishing feature is that the sample placement chamber 2 is divided into upper and lower chambers through a middle partition 15, wherein each chamber is correspondingly provided with an air inlet and an air outlet, and each chamber The position of the chamber corresponding to the air inlet is equipped with an airflow uniform dispersion device. It can satisfy small samples and control experiments at the same time.

[0026] The humidification system 10 in the present invention is a steam generator, the refrigeration system 6 is a dehumidification evaporator, and the heating system 7 is an electric heater.

[0027] In order to further increase the dispersion effect of the airflow, there are multiple air inlet pipes 9 in the present invention and they are arranged along the width direction of the sample placement chamber 2 .

[0028] like image 3 As shown, the air guide ...

Abstract

The invention discloses humidity and heat equipment capable of quickly uniformizing temperature and humidity, which is characterized by comprising a main box body, a sample placing cavity is arranged in the main box body, an air inlet pipe is arranged on one side of the upper part of the sample placing cavity, an air blower is arranged in the air inlet pipe, an outlet of the air inlet pipe is inclined towards the top surface of the sample placing cavity, an airflow uniform dispersion device is arranged at the top of the sample placement cavity, the airflow uniform dispersion device comprises a turbulent flow plate and an air guide assembly which are arranged at the top of the sample placement cavity, and the turbulent flow plate is provided with a plurality of hemispherical bulges which are dispersedly arranged; the bulge height of the hemispherical bulge decreases in a streamlined shape along the air flow direction blown out of the air inlet pipe, the equipment has the beneficial effects that the air field flow in the main box body can be changed, the air flow entering the sample placing cavity can be quickly and uniformly dispersed, and the air flow can be uniformly dispersed in the sample placing cavity; therefore, good temperature and humidity uniformity can be quickly realized on the same horizontal plane in the main box body.

Description

technical field [0001] The invention relates to the field of environmental experiment equipment, in particular to a damp heat equipment with rapid and uniform temperature and humidity. Background technique [0002] Long-life products in military industry, public service and other fields not only need to have superior performance / function, but also need to have excellent long-term storage performance and long-term reliable working ability, that is, they should have good environmental adaptability. In order to improve the environmental adaptability of long-life products and increase their ability to withstand harsh environmental influences, the research and production units of such products will use a series of test methods to reasonably evaluate their real storage life and sensitivity to the environment. Its purpose is to find out the weak links that affect the product's storage life and environmental adaptability through experiments, and make improvements to improve the prod...
