Definitions
- the invention relates to a heat exchanger, designed in particular for vehicles with an internal combustion engine and including an insulated container connected into a cooling circuit of the vehicle, inside of which a heat storage unit (HSU) filled with a phase-change material (PCM) is arranged.
- HSU heat storage unit
- PCM phase-change material
- EP 0 111 487 discloses a heat exchanger comprising a container connected into the cooling circuit of an internal combustion engine, in which container a heat storage unit (HSU) filled with phase-change material (PCM) is arranged.
- HSU heat storage unit
- PCM phase-change material
- phase-change material which phase-change material may be for example sodium bicarbonate phosphate, for heating of the cooling liquid, the engine, or the transmission oils prior to the next (cold) start-up of such internal combustion engine.
- HSU heat storage unit
- a heat exchanger designed in particular for vehicles with an internal combustion engine, consisting of an insulated container connected into a cooling circuit of the vehicle, where inside of the container a heat storage unit (HSU) filled with a phase-change material (PCM) is arranged, where according to the present invention the heat exchanger is characterized in that the heat storage unit (HSU) consists of a system of adjacently arranged aluminium extruded profiles, whose ends, provided with end caps to allow their filling with a phase-change material, are anchored in the face walls of the container, wherein the aluminium extruded profile, provided with at least one inner fin, has the shape of a square, rectangle, circular arc, or other known shape.
- the container is provided with insulation in the form of a vacuum.
- Advantages of the heat exchanger according to this invention are especially: the simplicity of its design; inexpensive manufacturing technology of the aluminium extruded profiles having high thermal conductivity, which conductivity allows rapid transfer of heat from the phase-change material (PCM) into the coolant medium or vice versa; and the need of only a single tool for the production of the required profile, from which the desired shape of the heat storage unit (HSU) is formed subsequently. Due to limited number of individual components and a simple manufacturing process, this design then ensures also a low failure rate.
- FIG. 1A is a side elevational view of a heat exchanger according to an embodiment of the invention.
- FIG. 1B is a cross-sectional elevational view of the heat exchanger taken along line A-A of FIG. 1A and showing a rectangular shape thereof;
- FIG. 2A is a side elevational view of a heat exchanger according to another embodiment of the invention.
- FIG. 2B is a cross-sectional elevational view of the heat exchanger taken along line A-A of FIG. 2A and showing a circular cross-sectional shape thereof.
- the heat exchanger consists of a container 1 having a rectangle or a circular shape in cross-section, which container 1 is provided with connection sockets 6 .
- the container 1 is also possible to manufacture the container 1 as having any other known shape in cross-section. It depends on customer requirements.
- a heat storage unit (HSU) filled with a phase-change material (PCM) 4 is arranged inside the container 1 .
- the heat storage unit (HSU) is formed by a system of aluminium extrusion profiles 2 arranged side by side with gaps 7 , which have in one case ( FIG. 1 ) a rectangular (or square) cross-section shape, and in the second case ( FIG.
- Each aluminium extruded profile 2 has a number of fins 3 and its ends are fitted with closing and sealing end caps (not shown) through which it is possible to fill the individual profiles 2 with a phase-change material 4 (e.g. sodium bicarbonate phosphate).
- a phase-change material 4 e.g. sodium bicarbonate phosphate
- the ends of individual profiles 2 are anchored (not shown) by any known method in face walls 5 of the container 1 .
- One of the possible and simple ways is for example the one in which the ends of profiles 2 are tightly fastened in with regard to shape matching openings formed in the face walls 5 of the container 1 .
- this arrangement provides adequate space for the expected thermal expansion of profiles 2 , which expansion is different from that of the container 1 .
- the very accurate definition of the position of the profiles 2 and thus, also of the cooling gaps 7 then allows even cooling of the entire circumference of the profiles 2 with a minimal pressure drop on the cooling side.
- the used fins 3 together with the material formation of the profiles 2 , increase the heat transfer, and therefore, also the charging (discharging) rate of the heat storage unit (HSU).
- the container 1 is then provided in a known way with external insulation (not shown) in the form of a vacuum.
- the aluminium profile 2 Upon connecting of the container 1 by the connection sockets 6 to the cooling circuit of an internal combustion engine, the aluminium profile 2 will so transfer thermal energy from the cooling liquid into the phase-change material (PCM) 4 placed in the HSU when the engine is warmed up and during the next about 12 hours recover it back into the cooling liquid after a cold start of the engine.
- PCM phase-change material
- the internal combustion engine is warmed up to the operating temperature faster, whereby the friction, the fuel consumption, as well as the CO 2 emissions are reduced.
- warming up of the engine before its actual start-up will also be possible.
- the container 1 can be included also within the circuit for circulating of the transmission or engine oils, for the purpose of their rapid heating up, and thereby, for reducing the frictional power loss of the engine.
