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.

摘要： The disclosed technology includes an air distribution baffle for distributing a flow of air from an air moving device to a burner assembly within a fluid heating device. The air distribution baffle can include a substantially flat portion and a raised portion extending upwardly from the substantially flat portion. The raised portion can include one or more faces having one or more apertures. The apertures can be arranged in a predetermined pattern or arrangement designed to provide a more uniform distribution of air flow and thus increase the combustion efficiency of the fluid heating device.

摘要： A water heater includes a heat exchanger, a heat pump, a first valve in fluid communication with the heat exchanger and the heat pump, and a controller configured to control the first valve. The first valve can be configured to direct water flow toward at least one of the gas heater or the electric heat pump. A second valve in fluid communication with the first valve and the heat pump can be provided, and the controller can be further configured to control the second valve. A water heater inlet and a water heater outlet can be included and in fluid communication with the first valve, and the controller can be configured to monitor a temperature of water entering the water heater inlet and control the first valve dependent upon the monitored temperature.

摘要： An apparatus for dispensing a liquid foodstuff, in particular milk, includes a heating device for heating the liquid foodstuff, which has a fluid path for the liquid foodstuff and an electric heater. The fluid path and heater are in thermal contact with a heat store made from a material of high thermal mass and conductivity, and the heat store is brought by the heater to an operating temperature which lies below 80° C., preferably below 70° C. The fluid path is connectable via at least one directional control valve to a flushing line via which water and/or detergent can be conducted through the fluid path for cleaning purposes. A control device is provided that is configured to heat the heat store of the heating device to a temperature above 100° C. to carry out thermal regeneration, and to open the directional control device one or more times for conducting water or detergent solution through the fluid path of the heating device heated to a high temperature.

摘要： An electric heating device includes a casing that forms inlet and outlet openings for the fluid to be heated and a circulation chamber as well as a connection chamber separated from the circulation chamber by way of a partition wall. A heat-emitting surface of a PTC heating element is exposed in the circulation chamber and is coupled in a heat-conductive manner to a PTC element. The PTC element is in electrically conductive contact, which via electrical conductor tracks with different polarities that are electrically connected in the connection chamber. The casing is a plastic casing provided with a shielding.
