PT8356U - HEAT EXCHANGE DEVICE FOR USE OF THE SENSITIVE HEAT OF THE COOLING WATER OF THE MOTOR DUM AUTOMOVEL VEHICLE - Google Patents

Description

2 2

; SUMMARY The present utility model application relates to a heat exchanger (1) that takes advantage of the water temperature of the engine cooling circuit of a motor vehicle to heat any liquid, for example water. It is constituted by a tubular body (2) inside which is placed in the axial direction a coil (3) with two end connections (4) and that is covered by the liquid to be heated. The tubular body 2 is driven by the cooling water of the engine as the crosspiece passing through frustoconical parts 5 and 7 and by cylindrical bushes 8 which connect to the engine cooling circuit. ij

The present utility model relates to a cable-exchanger device which, by taking advantage of the temperature of the cooling water in the motor circuit of a motor vehicle, heats any type of liquid. It is well known that heat energy is lost from the cooling water circuit of the engine and the problem which arises for the user and / or the driver of the vehicle is also known when there is no hot water, for example for the glass cleaner and even for other uses, such as drinking water and needing to warm it up, for example, to bottle a child, to drink coffee or even to wash your hands after having change from one wheel per hole or the like.

In all these cases and with the heat exchanger device according to the present utility model application, it is possible to have available and when desired hot water either for the specific uses of the car or, in the case of drinking water sanitary, for the needs that arise during the trip.

According to the present utility utility model heat exchanger device is placed after the wiper drive pump wherein said heat exchanger device belongs to or forms part of the circuit of |

I automotive engine cooling. j

If you wish to heat the water from the windscreen wiper, it is not | it is necessary to use an additional tank with clean water since, as is known, the vehicles dispose of the water device for the cleaner.

Thus, in the case of heating water for sanitary purposes, the vehicle will have placed in its proper place a water tank which is passed through the heat exchanger device of the utility model request. j

In any case, the heat exchanger device consists of a serpentine tube with two outlets

I that lie outside a portion or tubular body in the: inner of which is disposed axially to itself! i serpentine ! The tubular body defining the outer part or housing of the heat exchanger device terminates at its ends in tubular bushings having a suitable configuration to facilitate their coupling to the tubes or bushings of the heat exchanger circuit. cooling the passage of water to a temperature sufficient to transfer heat energy to the serpentine itself, into which the liquid to be heated passes and enters at one end and leaves the other. The material from which the parts forming the heat exchange device are made is variable, although it must have an optimal thermal conductivity coefficient so that the thermal gradient between the tubular body and the interior of the coil is minimal.

Of course, within the proper concept that underlies the utility model can be made certain changes as long as its fundamental principle does not change.

In order to more easily understand not only the constitution but also the proper use of the heat exchanger device in accordance with the present utility model application, a practical example of the embodiment is referred to below, exemplary and in no way limiting thereof, such | as shown in the accompanying drawings in which: Figure 1 shows an elevational view of said heat exchanger device; and Figure 2 shows a cross-sectional view in the longitudinal direction of Figure 1. The heat exchanger device 1 serves to heat water whether it is potable water or not, in any case placed in an appropriate tank, not shown, by extension, any type of liquid, located in the tank previously: mentioned and arranged in the cockpit of the engine. j

Claims (1)

The exchanger device 1 is constituted by a tubular body 2, within which and in the axial direction, a coil 3 is provided with two end outlets 4 for the inlet and outlet water to be heated. The tubular body 2 is topped by two cone-shaped pieces 5 which overlie the respective regions of the tubular body 2 at its ends 6. Each of the parts (5) has a progressive decrease of the cross section (7) through which the end outlets (4) of the serpent emerge. In this way this decrease in the cross-section of the parts 5 ends in straight zones 8 with flanges 9 which facilitate the retention of the coupling regions of the bushes or the water pipes, of the engine cooling circuit. Having sufficiently described the nature of the present utility model application and the manner in which it is to be realized in practice, it should be noted that the provisions set out above and represented in the accompanying drawings are susceptible to detailed modifications provided that they do not change their fundamental principle . A heat exchanger device which, by taking advantage of the water temperature of the engine cooling circuit of! a motor vehicle, heats any type of liquid; characterized in that it is constituted by a tubular body in the interior of which there is disposed in the axial direction a coil with two end connections, terminating the tubular body in two end bushes, in which the end parts of the bushings or tubes of circulation of the water of which passes through the interior of the tubular body and heats the liquid passing through the interior of the coil and entering through one of the connections thereof and exiting the other connection.
