摘要:
A heat exchanger arrangement, especially for a fuel-operated vehicle heater, has a pot-shaped heat exchanger housing (12) elongated in the direction of a longitudinal axis (L) with a circumferential wall area (14) and, in an end area (18), a bottom wall area (16). A flow space (30) for heat carrier medium is formed in the heat exchanger housing (12) with a circumferential flow space (32) and with a bottom flow space (34) that is in connection with the circumferential flow space. The heat exchanger housing (12) includes a first housing part (36) and a second housing part (38). The first housing part includes an outer circumferential wall (40), an inner circumferential wall (42) and an inner bottom wall (46) adjoining the inner circumferential wall. The second housing part includes an outer bottom wall (62), which is or can be connected to the outer circumferential wall (40) in one end area.

An on demand tankless water heater system that is capable of quickly delivering water within a desired temperature range. The tankless water heater provides a hybrid heating method that contains a primary heating system and a secondary heating system disposed in a buffer tank that cooperate to facilitate control of output water temperature during water usage. A pressure differential switch detects low flow demand and allows the secondary heating system to provide immediate heating to the water. This secondary heating system provides a faster temperature response and fine tuning of output water temperature.

A hot water supply system provided on a water pipeline, which includes a water inflow side and a water outlet side. The hot water supply system includes a plurality of water heaters; each includes a conduit, a heating device, a calculating unit, and a control unit. The conduit includes an inlet section, an outlet section, and a heating section in sequence, wherein the inlet section and the outlet section are connected with the water inflow side and the water outflow side respectively; the heating device heats the heating section; the calculating unit estimates a heating workload needed. If the heating workload of any water heater exceeds a predetermined upper limit workload thereof, the control unit of one water heater controls the other idle heating device to heat water, which ensures that water temperature of water provided to the water outflow side would reach a demanded water temperature.

摘要:
The invention under consideration relates to an electric heating device for heating a flowing medium with a housing, in which the at least one electric heating element of the electric heating device is held securely and fully shielded from the medium held in the circulation chamber by a separating wall that divides the housing into a heating chamber and a circulation chamber. The circulation chamber has inlet openings and outlet openings for introducing and removing, respectively, the medium. The heating element is preferably a PTC heating element and is held by means of a clamping force in a recess formed by the separating wall, said recess preferably projecting into the circulation chamber. The invention furthermore relates to a recuperator for converting electrical energy into thermal energy, particularly for an electric drive in a vehicle.

The invention relates to an electrical liquid heating device for a motor vehicle, said heating device comprising at least one module for heating the aforementioned liquid. The device is characterised in that the at least one heating module comprises: a substantially cylindrical chamber (13,113,213) having at least one heating means (114) for heating the liquid and defining a circuit (15,115,215) for guiding the liquid to be heated; and a control means (9,109,209) for controlling said at least one heating means (114), positioned facing one end of the cylindrical chamber (13,113,213).
摘要:
The present invention becomes possible to employ a main microprocessor with a relatively lower number of input ports, whereby while maintaining the performance and function of a water heater, the cost of a control apparatus is cut down. Some of sensors, adapted for measurement of various parameters which are for use in operational control of the water heater and in need of immediate response, are connected to a main microprocessor 31. The other sensors that are not in need of an immediate response, such as an ambient temperature sensor 36, are connected only to a sub microprocessor 32 if the main microprocessor 31 does not have any extra analog signal input port. The sub microprocessor converts an analog signal from the sensor 36 which is connected only to the sub microprocessor into digital data. And the sub microprocessor transmits the digital data to the main microprocessor through communication therewith.
