Abstract
An automotive water heater having application to a windshield of an automobile, which is able to produce hot water that can be sprinkled on the windshield to melt accumulated snow and frost, in which a water heater is mainly structured from a laminated assembled heating unit side joined to a heat conducting surface of an exchange bed. Heat quantity produced by the heating unit forms a heat balance function, which transfers the heat to the exchange bed, and water flow paths are defined interior of the exchange bed. The face joining of the laminated heating units is used to facilitate maintenance of component members and allow changing of the number of heating units assembled to the exchange bed, thereby providing choice to accommodate different power requirements.
Claims7
An automotive water heater, applying to a windshield of an automobile, and producing hot water that is sprinkled on the windshield to melt snow and frost, comprising:
- at least one laminated heating unit, the heating unit conducts electric power through a heating strip clamp connected to a plate electrode, an exterior of the plate electrode is joined to an insulating plate;
- a sealing back plate, the sealing back plate is joined to an exterior of the insulating plate;
- an exchange bed, the surface of the exchange bed is fitted with a plurality of adjacent and parallel heat conducting surfaces, the interior is composed of a plurality of longitudinal parallel ribbed plates joined as an integral body separating out a plurality of adjacent and parallel flow paths;
- a seal end cover, the seal end cover seals end surfaces of the flow paths established in the exchange bed, the seal end cover is provided with entrance-exit pipe orifices enabling the entrance and exit of water to the exchange bed, a space is gouged out of the sleeve connected position at the end surface of two related flow paths in an internal breadth of the seal end cover by an indentation to form a turnaround area for the two adjacent flow paths to flow into;
- another seal end cover, the seal end cover seals another end surface of the exchange bed to form an end surface sleeve connection, a space is gouged out of the sleeve connected position at the end surface of two related flow paths in an internal breadth of the seal end cover by an indentation to form a turnaround area for the two adjacent flow paths to flow into.
