摘要:
In a vehicle air-conditioner safety device, in the case in which an abnormality has occurred in a heating device that heats coolant with a heater: it is determined whether or not the abnormality is a restorable abnormality or a non-restorable abnormality; when the abnormality is determined to be the restorable abnormality, it is determined whether or not the restorable abnormality has been removed; heating by the heater is prohibited when the restorable abnormality or the non-restorable abnormality has occurred; and heating by the heater is restored when the restorable abnormality has been removed after heating by the heater is prohibited due to occurrence of the restorable abnormality. With the above-mentioned vehicle air-conditioner safety device, in the case in which the restorable abnormality has occurred in a heating device for a vehicle air-conditioner and the restorable abnormality has not been removed, because heating by the heater is prohibited, it is possible to prevent repetitive restoration and halt of heating by the heater.

摘要:
A heating device for heating of a fluid, particularly in a vehicle or vessel, comprising at least one heating element in a housing with a house wall and a fluid inlet and a fluid outlet. The wall or a part of this or a part of the house wall is a heat conductor for conducting heat between the heating element and at least one of the fluid channels. At least one chamber is defined by the at least one wall and a portion of the housing wall, or by walls in pairs between the fluid channels. The heating element is mountable in the chamber, which has an opening towards the outside of the housing. The opening is not fluidly connected to the fluid channels. The heating element can be a PTC element.

The invention describes a fluid system (10), in particular filter system, for fluid, in particular fuel, oil, water or urea solution, in particular of an internal combustion engine, in particular of a motor vehicle, having at least one heating device (26) for fluid, and a heating device (26). At least one heating chamber (14) has at least one inlet (18) and at least one outlet for the fluid. In the at least one heating chamber (14), at least one electrically operated heating element (32) is arranged between two holding bodies (28, 30) so as to be in electrical and thermal contact with at least one contact section (40, 2) of at least one of the holding bodies (28, 30). The fluid can flow through at least one inner volume region (58) between the two holding bodies (28, 30) and at least one outer volume region (62, 64) on an outer side, facing away from the at least one inner volume region (58), of at least one of the holding bodies (28, 30). In at least one enlarged section of the at least one inner volume region (58), a spacing between the two holding bodies (28, 30) is larger than a spacing between the holding bodies (28, 30) in a region of the at least one contact section (40, 52), at least on that circumferential side thereof which faces toward the at least one enlarged section.

Disclosed is a laminated heat exchanger wherein deterioration of sealing performance of a sealing portion of inlet and outlet header sections due to deformation of the sealing portion can be eliminated, said deformation being generated at the time of having a PTC heater in close contact between flat heat exchanging tubes by sandwiching and pressing the PTC heater between the tubes. A heat medium heating apparatus using the laminated heat exchanger, and an in-vehicle air-conditioning apparatus using the laminated heat exchanger are also disclosed. A laminated heat exchanger (18) is provided with: flat heat exchanging tubes (17), each of which is configured by bonding two molded plates (17A, 17B) that are respectively provided with outlet and inlet header sections (22, 23) on both the ends of a flat tube section; and a heat exchanger pressing member (16), which presses and brings the flat heat exchanging tubes (17) to be in close contact with each other, said flat heat exchanging tubes being laminated such that the inlet and outlet header sections (22, 23) communicate with each other through communicating holes (24, 25). With respect to the inlet and outlet header sections (22, 23), at least one of the input position (P1) of a pressing force applied

In a heating-medium heating unit (10) equipped with a first heating-medium circulation box (A) and a second heating-medium circulation box (B) which are in close contact with both surfaces of a PTC heater (40), in which heating-medium circulation passages (33, 54) are formed in the interior, and which are joined to each other in a liquidtight manner, wherein joining surfaces (M1 to M4) are sealed with liquid gaskets, the heating-medium circulation passages (33, 54) are provided with joining-surface cooling channels (C1, C2) that cool the joining surface (M1) which is sealed with a liquid gasket and on which the heat from the PTC heater (40) acts. The joining-surface cooling channels (C1, C2) are provided at positions closer to the joining surface (M1) than to the PTC heater (40).
