Description

Technical Field

[0001] This utility model relates to the field of heat meter technology, and more specifically, to a heat meter that can be sealed for protection. Background Technology

[0002] A heat meter is an instrument used to measure and display the heat released or absorbed by the heat transfer fluid in a heat exchange circuit. Currently, most heat meters on the market do not have a dedicated protective cover and are easily affected by external factors such as dust and moisture during use.

[0003] A search revealed that Chinese patent CN218381353U discloses an electromagnetic heat meter. Addressing the common problems of time-consuming replacement and disassembly, and difficult installation, in routine maintenance of currently used electromagnetic heat meters, this patent utilizes the cooperation of a first positioning protrusion and a first positioning groove, the cooperation of a second positioning protrusion and a second positioning groove in the positioning groove, and the synergistic effect of a guide groove and connectors. This effectively improves the stability of the PCB circuit board, facilitates subsequent PCB circuit board maintenance, increases maintenance efficiency, and extends the service life of the PCB circuit board. Furthermore, the cooperation of the mounting protrusion on the outer shell, the first mounting groove on the first side cover, and the second mounting groove on the second side cover improves the sealing performance of the electromagnetic heat meter, ensuring the normal operation of the PCB circuit board and thus effectively extending its service life.

[0004] During use, dust and moisture can easily get into the wiring connectors of the heat meter, affecting its lifespan. In addition, gaps usually form between the sealing gasket and the cover during long-term use, and the tightness between the sealing gasket, the cover, and the heat meter is insufficient. Dust and moisture can easily enter the heat meter from these parts, and the heat meter cannot be effectively blocked from entering. Over time, the accumulation of dust will affect the heat dissipation effect of the heat meter and may even cause short circuits in internal components. Utility Model Content
