This invention relates to the technical field of high-pressure heaters and discloses a heat dissipation device for a thick-film high-pressure heater, comprising a flow channel shell assembly, a flow channel heat-conducting component fixedly installed above the flow channel shell assembly, a liquid mounting cavity between the flow channel shell assembly and the flow channel heat-conducting component, and an equipment mounting groove inside the flow channel heat-conducting component; a heat insulation layer, a thick-film heater, and an inorganic heat-conducting layer are fixedly installed inside the equipment mounting groove; the flow channel heat-conducting component is provided with several sets of S-shaped guide fins, and the flow channel shell assembly is provided with a spiral guide component; this invention, through the matching arrangement of the thick-film heater and the inorganic heat-conducting layer, ensures that the thick-film heater is completely placed inside the equipment mounting groove, forming a physical isolation state from the antifreeze in the liquid mounting cavity, preventing direct contact with the liquid, and effectively avoiding damage such as corrosion, erosion, and scaling caused by the antifreeze to the heating element.
