Description

Technical Field

[0001] The utility model relates to the technical field of thermal environment test simulation devices, in particular to a heating cage of a thermal vacuum simulation system. Background Art

[0002] Currently, satellite mapping and satellite communications technologies are widely used in both military and commercial applications. These harsh operating environments place high demands on the adaptability of the satellite and its payload to the space thermal environment. Therefore, thermal design and testing are crucial to ensuring that the temperature levels, gradients, and stability of the satellite and its critical payloads meet normal operating requirements.

[0003] Currently, the devices used to simulate external heat flow in spacecraft ground-based thermal simulation tests include solar simulators, infrared heaters, and contact electric heaters. Taking into account factors such as cost, effectiveness, and test cycle, the heating cage of the infrared thermal vacuum simulation system has become the most commonly used external heat flow simulation device. Existing, commonly used infrared thermal vacuum simulation system heating cages primarily consist of metal heating strips fixed to a frame. These heating cages offer advantages such as simple design principles, low structural complexity, and high operational reliability. However, due to their high thermal inertia, the heat dissipation rate of the test piece within the infrared thermal vacuum simulation system's heating cage is extremely slow during low-temperature testing, failing to meet the low-temperature requirements after cooling. This makes it difficult to quickly switch between different temperature conditions during thermal radiation testing, resulting in significant errors in the environmental simulation of different temperature conditions, seriously affecting the accuracy of experimental results.
