- 2. Background of the Invention
- Hot property is a sort of important properties for an electrical device such as computer, sever, notebook and so on. Hot property reflects an operation state of the electrical device in a different temperature environment. When hot property of an electrical device is tested, a kind of simulation temperature environment is needed. Traditionally, a hot box is designed for testing an electrical device placed therein. The temperature in the hot box can be adjusted within a range of necessary temperature. Consequently, the hot box provides a kind of simulation temperature environment for testing the electrical device.
- In fact, the electrical device is placed in natural convection environment and temperature of every part of the electrical device is approximately uniform. However, if the hot box cannot simulate a real temperature environment, the test for hot property of the electrical device is no effect. Understandably, some attempts have been taken to introduce an improved hot box.

The thermostat includes a T type thermocouple disposed in the box, a double-acting relay, a temperature controller and a plurality of single-acting relays. The power supply includes a transformer, a bridge clipper diode and a capacitor. The T type thermocouple measures temperature in the
box 1 and transfers the temperature to the temperature controller. The temperature controller and the relays jointly control the fan and the heater. The fan starts to operate and the heater is cut off when the temperature is higher than the testing temperature. The fan is cut off and the heater is out of service when the temperature is lower than the testing temperature. Therefore, the testing temperature is maintained. In addition, the heat that the power resistors generate is a mixture of emanation heat and radiation heat, thereby solving a problem that the heat is non-uniformly distributed. The heat in the box is free convection, thereby simulating the natural environment. - Other advantages and novel features of the present invention will be drawn from the following detailed description of preferred embodiment of the present invention with the attached drawings, in which:

Consequently, thediodes heat generating devices power resistors 60 start to operate and generate heat. The heat that thepower resistor 60 generates is a mixture of emanation heat and radiation heat, thereby solving a problem that the heat is non-uniformly distributed. In addition, the heat in thebox 1 is free convection, thereby simulating the natural environment. - Alternatively, the
T type thermocouple 33 can be replaced by other temperature sensors. In order to lower temperature rapidly, more fans are needed. The number of heat generating device can be decreased and increased in light of factual situation. - While the present invention has been illustrated by the description of preferred embodiment thereof, and while the preferred embodiment has been described in considerable details, it is not intended to restrict or in any way limit the scope of the appended claims to such detail.
