Internal heat type heat loading device capable of heating up rapidly

Abstract

The invention discloses an internal heat type heat loading device capable of heating up rapidly. Two horizontal lamp tube integrated boards are fixedly connected by a vertical connecting rod; a plurality of vertical lamp tubes are installed between two lamp tube integrated boards and are uniformly distributed around a virtual circle; two wiring terminals at two ends of each of the plurality of lamp tubes are connected with the two lamp tube integrated boards; the two lamp tube integrated boards are provided with wiring terminals for an externally connected power supply; a reflection board is formed by connecting and closing a plurality of reflection board units with radial circular arc cross sections; the plurality of reflection board units are in one-to-one correspondence with the plurality of lamp tubes; the lamp tubes are coaxial to the reflection board units and are positioned in arc-shaped groove regions at the outer sides of the corresponding reflection board units; the reflection boards and all the lamp tubes are all arranged in vertical casing pipes. According to the heating device, light rays emitting from the inner sides of the lamp tubes are reflected outward by the reflection board, so that the heat utilization ratio of the lamp tubes is increased; meanwhile, a radiation heat condition mode is adopted, the internal heat type heat loading device has high heat loading capacity with high temperature rise velocity and high heating temperature.

Description

technical field [0001] The invention relates to a heat loading device, in particular to an internal heating type heat loading device with rapid temperature rise. Background technique [0002] Thermal loading devices are often used in materials, chemical engineering, metallurgy and other engineering fields. With the continuous development of new materials and new processes, higher requirements are put forward for the heating power, temperature rise time and energy consumption cost of thermal loading. For example, the heating temperature required for the preparation of rubber asphalt, which can significantly improve the mechanical properties and performance of asphalt pavements, and the test temperature for the temperature resistance of airgel materials have reached above 600°C; With a wide range of working fluids, on the premise of ensuring sufficient resolution, rapid temperature rise can realize rapid analysis of its composition and physical properties.

Problems solved by technology

[0003] Existing heat loading devices mostly use electric heating, limited by the resistance wire material and heat conduction and convection as the main heat conduction methods, the medium is required to transmit heat energy, the loss of energy is large, and the heat conduction needs to be in contact with the object to be heated, the maximum The heating temperature and temperature rise rate are generally small. Due to the slow thermal loading rate and safety factors, it is often suitable for long-term thermal loading with low power. Heating the heated object to a higher temperature in a short period of time cannot reach the high temperature working area above 600°C, and there are disadvantages such as large energy consumption, low temperature rise rate, low efficiency, and poor production continuity.
