Abstract

A heat exchanger is arranged to transfer heat from exhaust gas and/or vapour produced by a vehicle to the load carrying bed 4 of the vehicle, thereby to heat (or maintain at an elevated temperature) material being transported by the vehicle. The heat exchanger preferably comprises fabricated metal ducting 6, 7 arranged to direct gas or vapour from the vehicle exhaust system (9, fig. 1) into heat exchange contact with the underside of the load carrying bed. The load carrying bed is heat conductive (typically of metal). <IMAGE>

Description

Method and Apparatus for heating the load carrying bed of a vehicle.
The present invention relates to a method and apparatus for heating the load carrying bed of a vehicle such as a truck, lorry, trailer or the like.
It is common practice for vehicles to be loaded with hot material typically amorphus aggregated material to be distributed to a location where the material is needed. Usually, it is a requirement that the material remains relatively hot on arrival at its destination but in practice cooling occurs due to ambient temperature and time of transport. An example of such a situation is where heated asphalt cools as it is transported by vehicle to a location of damaged roadway which needs repair.
The present invention seeks to at least ameliorate this problem.
According to a first aspect of the present invention, there is provided apparatus for heating the load carrying bed of a vehicle, the apparatus comprising heat exchange means arranged to transfer heat from exhaust gas and/or vapour produced by the vehicle to the load carrying bed of the vehicle.
It is preferred that the heat exchange means comprises ducting arranged to direct gas and or vapour from the vehicle exhaust system into heat exchange contact with the underside of the load carrying bed of the vehicle.
In a preferred embodiment, the heat exchange means comprises a part of the vehicle exhaust system such that the exhaust gas and/or vapour passes in sequence, from the internal combustion engine of the vehicle, via the heat exchange means and subsequently exhausts to atmosphere.
It is preferred that the heat exchange means defines a flow path on the underside of the vehicle bed, advantageously extending longitudinally and also preferably transversely of the vehicle load carrying bed.
Desirably, the flowpath is arranged such that along respective lengths of the flowpath, the flow of exhaust gas and/or vapour is in substantially opposed directions.
It is preferred that the heat exchange means comprises a plurality of lengths of interconnected pipe or tube preferably of fabricated metal construction defining the flowpath.
Desirably certain lengths of tube or pipe interconnect with other lengths of tube or pipe substantially at right angles.
It is preferred that the load carrying bed of the vehicle is arranged to be heat conductive such that heat may be conducted from the heat exchange means to the material loaded on the bed.
Desirably the heat exchange means is substantially fixed to the underside of the load carrying bed.
In certain embodiments, the load carrying bed will be arranged to be pivotally tippable relative to the remainder of the vehicle chassis. In such an embodiment it is preferred that when in the non-tipped position, an inlet port provided in the heat exchange means is arranged to mate with an outlet port of the exhaust system thereby to permit communication of gas and vapour from the exhaust system to the heat exchange means.
According to a second aspect of the invention, there is provided a method of heating the load carrying bed of a vehicle, the method comprising directing exhaust gas and/or vapour produced by the vehicle into heat exchange contact with the load carrying bed of the vehicle.
The invention will now be further described in a specific embodiment, by way of example only, and with reference to the accompanying drawings, in which.
Figure 1 is a schematic side view of a vehicle having a load carrying bed heated in accordance with the invention; Figure 2is an underside plan view of the heated load carrying bed of the vehicle shown in Figure 1; and Figure 3 is an enlarged view of detail A shown in Figure 1.
Referring to the drawings there is shown a vehicle 1 comprising a trailer 2 hitched to a cab 3. Trailer 2 is provided with a load carrying bed 4 arranged to support a hot load such as for example hot asphalt.
Welded to the underside of load carrying bed 4 is a network 5 of fabricated metal pipes comprising a series of pipes 6 arranged side by side and extending longitudinally, and a pair of transversely extending pipes 7 connected at either end of the network.
An inlet or entry port 8 is provided in one of the pipes 6 and arranged to be in communication with the exhaust duct 9 of the internal combustion engine of cab 3. Hot exhaust gas from the internal combustion engine of the cab is therefore directed into the pipe network 5 via inlet port 8. Baffles 10 internally of the network 5 are arranged to direct the hot exhaust gas along the path shown by the arrows in Figure 2 such that flow in adjacent pipes 6 is in opposed directions. Ultimately, the hot exhaust gas exhausts to atmosphere via outlet 11.
The network 5 is in thermally conductive contact with the underside of the load carrying bed 3 and therefore effectively acts as a heat exchanger transferring heat energy from the hot exhaust gas to the material carried on bed 3. In this way it is possible to maintain the load at an elevated temperature for a substantially longer period than would otherwise be the case during transit.
Referring now to Figure 3, the load carrying bed 3 is capable of pivotally tipping about its rear axle to unload the material being carried. In order to ensure correct coupling between inlet port 8 and exhaust duct 9 a spring 13 loaded location plate 12 is fixed to the chassis and centred around exhaust duct 9.
