摘要： PROBLEM TO BE SOLVED: To enhance the efficiency of heat transmission to a circulating fluid from a heating chamber, and simultaneously to promote the stable molding of a housing constituent member for partitioning the heating chamber, in a vehicular heat generator. SOLUTION: Plural guide grooves 20a and 20b are formed in a rear end face 5d of a front partition plate 5 for partitioning off a heating chamber. These guide grooves 20a and 20b like that are set up on an inner wall surface of this heating chamber. In addition, the guide grooves 20a and 20b are provided with each R-form bottom corner 21b in space between the bottom part 21 and both side walls 22. Form of the bottom corn 21b is approximable as a curved surface of a radius of curvature R1 with a center of curvature C1 as the center. Thus, since each bottom corner 21b of the guide grooves 10a and 20b is formed into the R-form, silicon oil to be offered to a shearing action in the heating chamber is smoothly and quickly circulating in a flow along the guide grooves 20a and 20b without being obstructed.

摘要： PROBLEM TO BE SOLVED: To facilitate circulation of a viscous fluid to the front and rear of a rotor in a heating chamber so as to delay degradation of the viscous fluid. SOLUTION: A rotor 15 has forward inclined communicating holes 16 piercing longitudinally in an axial direction and extended in a non-radial direction (rotating tangential direction) of the rotor and also extended inclining onto the front end face 15a side in relation to the rotating direction P of the rotor 15. Each forward inclined communicating hole 16 is so formed that its end part on the rotating direction P side of the rotor 15 is opened to the front end face 15a of the rotor 15 and that its end part on the reverse side to the rotating direction P of the rotor 15 is opened to the rear end face of the rotor 15. When the rotor 15 is rotated, a viscous fluid on the front side of the rotor 15 is taken into the rotor rotating direction side opening end part of the forward inclined communicating hole 16 and discharged to the rear side of the rotor 15 from the rotor rotating direction reverse side opening end part of the forward inclined communicating hole 16. Circulation of the viscous fluid in a heating chamber is improved by the generation of forced flow of the viscous fluid.

This heat is heat-exchanged into circulating water in front and rear water jackets FW, RW through front and rear partition plates 2, 3. In this case, knotched sections 25a, 27a as communicating passages in the radial direction of the labyrinth grooves 26, 29 are formed in a fin 25 of the rotor 24 and a fin 27 of the front partition plate 2, and similar knotched sections 25a, 28a are formed in a fin 25 which protrudes on a rear side of the rotor 24 and a fin 28 of the rear partition plate 3.

The heating chamber 7 is charged with silicone oil to produce heat through the shear thereof caused by the rotation of the rotor 13. The heating chamber 7 is enclosed by a pair of walls situated in its front and rear and by the cylindrical peripheral wall, and the front and the rear end faces and the outer periphery of the rotor 13 face the walls and the peripheral wall. The rotor 13 is bulged outward at the center of its both front and rear ends.

摘要： PROBLEM TO BE SOLVED: To facilitate the mounting of a viscous heater of a larger heating capacity to a vehicle or the like. SOLUTION: A heater housing comprises a center housing 1, a cylinder 2, a front housing 5 and a rear housing 6. The heating housing is internally sectioned to have a heating chamber 7 and a radiation chamber or water jacket 8 surrounding the heating chamber 7. The heating chamber 7 has therein a driving shaft 12 and a rotor 15 which are rotatable together, and contains silicone oil as viscous fluid. The rotor 15 is formed on its outer periphery with a plurality of skew guide grooves 20. As the rotor 15 rotates, the skew guide grooves 20 forcibly transfers the oil in the heating chamber 7 toward the front or rear end of the rotor 15 to thereby control the flow of the oil within the heating chamber 7.
