FIELD: chemical industry. ^ SUBSTANCE: invention relates to fluid heaters and can be used in chemical industry while heating, combining advantages as heaters with heat transfer through the mass, as heaters with direct contact. Proposed heater includes bulky structure, in which there are implemented passages for creation of labyrinth for flow of heated medium, herewith size and location of passages provides location in it heater rod group so, that medium pass by passage with direct contact with heaters rod. In space between passage walls and heater rod, in a contact with it, it can be located coil spring or other coil element for providing of flow homogeneity around rods. It can be installed heat sensor, allowing direct contact with heating element, and to the sensor it can be installed bulky for withdrawal of heat excess from sensor during transient. ^ EFFECT: heater correct functionability ensured by heat passage improvement. ^ 17 cl, 11 dwg |
