The tubular main body is formed by extrusion, the production process is mature, and the extrusion cost is low. The dot matrix support core plate and the left and right edge sealing plates are injection molded, so that the dimension is accurate, and the follow-up accurate processing is convenient. The welding process of the vacuum heat insulation board is the most important factor influencing the internal vacuum degree of the board, gas can be generated in common hot-melt welding, the internal vacuum degree of the board can not be ensured, and the heat insulation performance of the board is seriously influenced. The embodiment adopts an ultrasonic welding process, the left and right edge sealing plates and the tubular main body are simultaneously placed in a vacuum machine, ultrasonic welding is carried out in a vacuum state, gas is not generated, and the vacuum degree requirement can be ensured. After the whole plate is processed, the outer side of the plate is coated with a film, and the plated metal material can be aluminized or silvered.
