Description
The invention relates to a preheating device for a water-cooled motor vehicle engine with an external heating appliance, i.e. independent of the engine, water being used as the heat-transfer medium for the heating system.
Known preheating devices are mostly based on air as the heat-transfer medium (cf. DE-OS 38 32 967, DE-OS 38 34 540). However, the use of air as the heat-transfer medium is not suitable for low outside temperatures owing to its low thermal capacity. Preheating devices are also known which use water as the heat-transfer medium with an external heat source (DE-OS 23 51 472, DE-OS 37 30 598, AT-PS 17 99 94). However, when using water as the heat-transfer medium only the engine or the engine and the driver's cab in combination are preheated by an external heat source. Admittedly, the engine or the engine and the driver's cab can be heated even at relatively low outside temperatures. However, known preheating devices using water as the heat-transfer medium are not designed for extremely low outside temperatures. In fact, it cannot be guaranteed that the known water-glycol mixture used as the coolant will provide the required lowtemperature resistance of -60T. The freezing point of the water-glycol mixture is at maximum -480C (with a water-glycol mixture ratio of about 1:1).
The object of the invention is to devise a preheating device of the type defined in the introduction, which is of simple and compact construction and is reliable in operation, even at extremely low outside temperatures in the region of -600C.
The object forming the basis of the invention is achieved by the means indicated in the characterising part of Claim 1.
2 The subject-matter of the invention is developed advantageously by the features of sub-claims 2 to 10.
The essential principle of the invention is to provide a combined heating system which is connected with the coolant circuit of a water-cooled motor vehicle engine and which has heating sectors which comprise at least one engine preheater, an interior heater and a battery heater. Additionally, the heating sectors may include fuel and oil heaters, as well as a transmission heater. One or more external heating appliances, i. e. heating appliances with an external power supply independent of the engine, with associated circulating pump are provided in the heating system, the heating appliances preferably being operated with diesel oil or electric energy. In addition, at least one continuously operating temperature controller can be provided in the heating system, which automatically starts the heating system when the temperature falls below a limit temperature, or the heating appliance or appliances can be started by a manual switch, and it is also possible for a heating system to be provided both with temperature controllers and with manual switches.
The heat transfer to the individual heating sectors is effected via existing or supplementary branch ducts of the engine-cooling system. Accordingly, all the heating sectors are connected to the cooling system. By series or parallel connections it is possible to determine which components are to be heated first. A priority circuit, which for example is temperature-dependent, can be provided by means of actuating elements (for example solenoid valves) and a control system.
Basically there are two heating possibilities. First possibility;:
It is well known that with a mixing ratio of approximately 1:1 (with a water-glycol mixture) a lowest freezing point of coolant of about -480C is achieved. To obtain the required low-temperature resistance at -600C, the temperature controller integrated into the heating system is 3 activated, which starts the preheating device when the temperature falls below a limit temperature, so as to reliably prevent the cooling system from freezing. Since the heating-up procedure is already determined by circuitry or control, the heating-up to the starting temperature can be started and/or terminated by simple manual switching on of the heating appliance. Second possibility:
The glycol-water mixture, which is viscous at -600C, is caused to circulate by way of a suitable circulation pump and is heated relatively rapidly by way of the heating system. High circulation temperatures are quickly attained as a result of the rapid change in consistency.
Therefore, the invention makes it possible to expose the motor vehicle to even lower outside temperatures than would be permitted by the coolant, without the danger of being subject to freezing up. The priority heating circuit enables the important assemblies to be rapidly heated to the starting temperature. The combined device according to the invention is in general of particularly simple and compact construction and, moreover, is particularly reliable in operation.
The invention will be illustrated in more detail below on the basis of examples of embodiment with reference to the accompanying drawings:
Figure 1 shows a preheating device for a water-cooled motor vehicle engine with individual heating sectors of a combined heating system connected in parallel; Figure 2 shows a preheating device similar to Figure 1 with a priority heating circuit for the heating sectors of the heating system, and Figure 3 shows a preheating device similar to Figure 1 with heating sectors of the heating system connected in series.
According to Figure 1, a preheating device (20) for a water-cooled vehicle engine (8) comprises a heating system, which is connected to the coolant circuit of the engine, 4 having an engine preheater (21), a driver's cab interior heater (2) and a battery heater (22) as heating sectors. It is possible to connect further heating sectors, such as fuel and oil heaters, as well as a transmission heater. The heating sectors are equally connected in parallel.
Additional heat energy is supplied to the heating system by an external, i.e. external energy storing, heating appliance (1) which is integrated into the heating system, and a circulating pump (6). It is also possible for a plurality of external heating appliances (1) to be provided.
One or more temperature sensors (3), which are disposed at suitable locations (here, for example, the radiator), continuously provide information to the temperature controller (4) regarding the temperature of the system.
The temperature controller is continuously in operation and cannot be switched off. The heating appliance (1) and the circulating pump (6) are started when the temperature falls below an outside limit temperature.
The operation of the temperature controller (4) can be effected by a thermocouple with a downstream electronic circuit or by a suitable temperature-dependent switch which directly actuates the heating appliance (1) and the circulating pump (6).
In Figure 3 all the sectors are connected in series. First, the engine (8), then the interior heater (2) and, finally, the battery housing (7) of the battery heater (22) are supplied with heat.
According to Figure 2, the preheating strategy is controlled by a control unit (9) of a priority heating circuit. A selector switch (10) makes it possible to preselect a given strategy. The individual sectors are coupled and uncoupled via actuating members 49a, 9b, 9c). In this variant of embodiment the temperature controller (4) is integrated into the control unit (9). In this case the temperature sensors (3) supply the control unit (9) with the necessary signals for the temperature controller operation. Furthermore, it is also possible for the heating-up procedure to be additionally influenced via these signals.
The warming-up procedure is switched on and off by a manually operated switch (5).
The temperature controller or controllers (4) also ensure(s) that the water temperature is always maintained in the region of a -45"C.
On the other hand. the circulating pump (6) must be able to circulate the viscous water/glycol mixture even at water temperatures of -550C to -600C and to heat it rapidly, either a) via a small short-circuit circulation and a constant pressure on the remaining cold system so that the relatively cold column of liquid is rapidly fed to the heating appliance (1), or b) via a pump of substantial dimensions which feeds said column of liquid through the heating appliance (1).
The battery temperature is monitored via another temperature sensor (3a) disposed in the battery housing (7). When the maximum admissible battery temperature is reached, the battery heating is terminated via an actuating member (9c or 10).
All the novel features mentioned in the description and/or illustrated in the drawings are part of the invention either alone or in a suitable combination, even if they are not explicitly claimed in the claims.
