Description

Technical Field

[0001] The invention relates to the technical field of marine refrigeration equipment, and in particular to a fixing bracket, a safety device and refrigeration equipment. Background Art

[0002] In order to save space, marine water coolers are developing in the direction of small size. When the size of the water cooler is reduced, its internal space is reduced, but the electric heating with the same power before the size reduction is maintained, which is bound to leave hidden dangers for the safety of electric heating. Electric heating safety is an uncompromising hard requirement for marine air conditioning equipment, so the electric heating safety test has become an important part of the development process of marine water coolers. The temperature limiter and fuse (hereinafter referred to as the electric heating safety device) are important components to ensure that the electric heating stops working under abnormal conditions. Their distance from the electric heating tube (heat source) determines whether they can disconnect the power supply in time. Their installation location becomes the main problem of electric heating safety, and the fixing bracket of the electric heating safety device also becomes the key.

[0003] The applicant has found that the prior art has at least the following technical problems:

[0004] In the prior art, an installation position of an electric heating safety device is first anticipated. This step has no simulation calculation and no empirical basis. Different specifications of the internal space of the whole machine and different specifications of the electric heating tubes will affect the change of the internal thermal field. It is impossible to ensure that the electric heating safety device can reliably disconnect the power supply when the internal temperature is too high. In other words, it is impossible to determine the best installation position of the electric heating safety device. An immovable fixed bracket is made by guesswork. If it is subsequently proved that this fixed position cannot guarantee that they can reach the specified temperature in time, thereby disconnecting the power supply in time to prevent the electric heating tube from continuing to heat up and causing the internal temperature of the whole machine to continue to rise and cause non-metallic parts to burn or deform, it is necessary to change the drawing and then process an electric heating bracket to change the installation position, which takes a long time and wastes resources.
