Abstract

The invention discloses a heater protection device. The heater protection device comprises a protection body used for isolating a heating tube from a heating groove, the protection body is provided with an inner cavity capable of being filled with a liquid, and the inner cavity is provided with more than one opening, wherein a pressure alarm device is arranged at the at least one opening. The embodiment of the invention further provides a corresponding system. According to the heater protection device provided by the embodiment of the invention, the protection body and the liquid filled in the inner cavity play a role of isolation, and after a dry-burning phenomenon is generated, the heating groove can be prevented from being on fire by heating; the liquid filled in the inner cavity can be expanded by heating or generate steam, so as to drive the pressure alarm device to work; thus, further protection can be provided after the dry-burning phenomenon is generated, so that the occurrence of a fire can be avoided.

Description

technical field [0001] The invention relates to the technical field of heaters, in particular to a heater protection device and system. Background technique [0002] The manufacturing process of Printed Circuit Board (PCB) requires a large number of electroplating equipment. Since the electroplating solution needs to work at a certain temperature, the electroplating equipment needs to be equipped with heating devices such as electric heating tubes. [0003] In order to achieve better heat exchange, the electric heating tube is usually installed directly in the electroplating tank of the electroplating equipment, and is in direct contact with the inner wall of the electroplating tank. The electroplating tanks of most electroplating equipment are made of corrosion-resistant flammable materials such as polyvinyl chloride (PVC) or polypropylene (PP). There is a great security risk in this. For example, some fault conditions will cause the heating tube to "dry burn". After the...
