Description

Technical Field

[0001] This utility model relates to the technical field of industrial instrument structure, specifically to a heat dissipation device for industrial instruments with excellent airtightness. Background Technology

[0002] Industrial instruments refer to flow measurement instruments such as gas and liquid turbine flow meters, vortex flow meters, and electromagnetic flow meters, as well as industrial instruments such as pressure switches, differential pressure switches, pressure transmitters, differential pressure transmitters, level switches, level gauges, and temperature and humidity recorders.

[0003] During use, the operating module within the industrial instrument data intelligent acquisition and sharing device generates a significant amount of heat due to prolonged operation. Over time, this accumulated heat can negatively impact the module's operation. An existing heat dissipation structure, such as the one described in patent publication number CN219269455U, utilizes a micro-pump to deliver coolant from a cooling tank to a cooling shell. Because the heat sink is in close contact with the top of the module, the heat generated by the module is conducted to the coolant in the cooling shell, aiding in rapid cooling and improving the module's heat dissipation effect, thus providing a suitable operating environment.

[0004] However, due to the complex structure, high cost, and poor practicality of this device. Utility Model Content
