    摘要： Various implementations include a hot water heating system having a spine and two or more water heating units. The spine includes a top surface defining one or more top openings, two or more coupling areas, and cold water, hot water, and fuel manifolds. One or more top openings provide access to a cold water manifold inlet, a hot water manifold outlet, and a fuel manifold inlet. At least one of the coupling areas is located above another coupling area when the spine is oriented with the top surface facing upwardly. The water heating units are coupled to coupling areas such that a cold water inlet of the unit is fluidically coupled to the cold water manifold outlet, a hot water outlet of the unit is fluidically coupled to the hot water manifold inlet, and a fuel inlet of the unit is fluidically coupled to the fuel manifold outlet.

    摘要： An electric heating device includes a housing having a partition wall which separates a connection chamber from a heating chamber for dissipating heat and from which at least one receiving pocket, protruding into the heating chamber as a heating rib tapering towards its lower, closed end protrudes. A PTC heating element includes at least one PTC element and conductor tracks for energizing the PTC element with different polarities. The conductor tracks are electrically conductively connected to the PTC element and are electrically connected in the connection chamber. A pressure element is received which holds heat extraction surfaces of the PTC element abutted against oppositely disposed inner surfaces of the receiving pocket. The pressure element includes a sheet metal strip which, by punching and bending, forms spring segments protruding from the plane of the sheet metal strip. The spring elements are provided in a planar manner distributed over a heat extraction surface of the PTC element provided adjoining the respective pressure element.

    摘要： A heating device is designed to heat a liquid while minimizing current that is induced in the liquid. The heating device includes a radiant heat source and a heated member such that the radiant heat source applies radiant energy to the heated member and the heated member is positioned within a vessel. The radiant energy from the radiant heat source is radiated across an empty or gas-filled gap between the radiant heat source and the heated member and the heated member transfers heat to the liquid.

    摘要： The present invention discloses a film type liquid heater and a uniform heating method thereof. End fixation plates are arranged at two ends of a barrel. A heating pipe is arranged in the barrel. Pipe ports run through the two end fixation plates, respectively. Connecting pipes are arranged in the pipe ports. Sealing connection components are arranged at inner ends of the two connecting pipes. A heating film layer is coated outside the heating pipe. Electrode layers are connected left and right sides of the heating film layer, and the electrode layers are connected to an external power supply. An insulating layer is coated outside the heating film layer. A flow splitting column is fixedly connected in the heating pipe. A heating chamber is formed between an inner side of the heating pipe and the flow splitting column. Flow splitting grooves are formed at left and right ends and on the inner side of the flow splitting column. Two outer ends of the flow splitting grooves are communicated with the connecting pipes, and the flow splitting grooves are communicated with the heating chamber. The heating film layer is electrified to generate heat. The heat is conducted inward to the heating pipe and the flow splitting column, and conducted outward to the barrel. Liquid flows into the heating chamber through the connecting pipes and the flow splitting grooves, so that the heating uniformity of the liquid flow flowing through the heating chamber is improved.
