1, high and low temperature test chamber is more difficult than the oven technology 2, on the surface, there is not much difference between
the two.
The practical difficulty is that when the air is heated to a high temperature of more than 350 ° C, the movement of the gas becomes very difficult to control, even under the condition of forced blowing, the flow of the gas is still disordered, so the design requirements for the phoenix road are very high
.
For different chamber sizes, the air duct should vary
.
In order to obtain reasonable data, it is often necessary to go through repeated experiments
.
In order to obtain a higher uniformity index, the cost of manufacturing a high and low temperature test chamber is much
larger than that of an oven.
3, high and low temperature test chamber: high temperature area ruler RT + 0 ~ 150 °C, low temperature area RT +0 ~ -70 °C, humidity: 20% ~ 98% oven: high temperature zone ruler RT + 0 ~ 500 °C, so the price of high and low temperature test chamber is more expensive than the oven price of part of the reason
