摘要： An electrical fluid heater (100) includes a housing and electric heating elements (20). The housing forms a fluid flow chamber (10) formed with an inlet (12) for ingress and an outlet (14) for the egress of fluid. The heating elements (20) disposed inside the fluid flow chamber (10) are heated by resistive heating to heat fluid flowing around thereof as the fluid flows in the fluid flow chamber (10) from the inlet (12) to the outlet (14). The electric heating elements (20) are formed as heating bars extending through the fluid flow chamber (10) from one extremity to the other. The electrical fluid heater (100) includes intermediate baffles (30) arranged within the fluid flow chamber (10) to redirect fluid received inside the fluid flow chamber (10) to uniformly distribute fluid within the fluid flow chamber (10) and define a torturous fluid flow path between the inlet (12) and the outlet (14).

摘要： A fluid heater (100) includes a first and a second end plate (10) and (20), heating elements (30) and intermediate plates (40). The first end plate (10) includes an inlet (12a) and an outlet (12b) for ingress and egress of fluid into and out of the fluid heater (100) to cause the fluid to follow a U-turn trajectory. The intermediate plates (40) and the heating elements (30) are arranged alternatively with respect to each other. The adjacent intermediate plates (40) define fluid flow passes adjacent the at least one corresponding heating element (30) to permit heat exchange between the fluid and the at least one corresponding heating element (30). The second end plate (20) includes fluid deflecting walls (50) formed on its surface to promote a homogeneous distribution of fluid in a first portion (20a) and a second portion (20b) of the second end plate (20).
