- FIG. 1 is a sectional view of a housing for elnhausen a power electronics according to an embodiment of the present invention
- Fig. 2 is a perspective view of a charger for a vehicle according to an embodiment of the present invention
- FIG. 3 is an illustration of a mounting solution for a heat sink according to an embodiment of the present invention.
- Figure 4 is a schematic representation of a vehicle with a power electronics system according to an embodiment of the present invention.
- FIG. 1 shows a sectional view of a housing 100 for the purpose of housing a power electronics 102 according to an exemplary embodiment of the present invention.
- the housing 100 has a trough 104 made of a plastic material.
- the power electronics 102 can be arranged on a bottom 106 of the trough 104.
- the power electronics 102 is shown disposed on the floor 106.
- the heat sink 1 10 is executed here around an edge of the wall 108 circumferentially.
- the heat sink 10 has an inner part 1 12 arranged on an inner side of the trough 104 and an outer part 14 arranged on an outer side of the trough 104.
- the inner part 1 12 and the Au WOteil 1 14 connected by a thermal bridge 1 16 thermally conductive.
- the thermal bridge 1 16 extends over the edge of the wall 108.
- Peltier elements 1 18 are arranged between the inner part 12 and the outer part 14.
- the Peltier elements 1 18 transport when applying an electrical voltage heat from one side of the Peltier element 1 18 to the other side of the Peltier element 1 18.
- the Peltier elements 1 18 are connected to a control unit 120, which is part of the power electronics 102. By the control unit 120, the Peltier elements 1 18 are driven so that they transport heat from the inner part 1 12 to the outer part 1 14.
- the heat sink 1 10 ribs 122 which increase the surface of the heat sink 1 10 in order to achieve improved heat transfer.
- an efficient mechanism for heat dissipation or cooling of a power electronics module 102 is presented, which is mounted in a sealed, airtight and thermally non-conductive (plastic) housing 100.
- This technique can be applied to any power electronics 102 housed in a sealed plastic housing 100.
- a cost effective, simple, innovative solution to such a heat dissipation problem is presented herein.
- the housing 100 in the closed state has a seal against air, dust and moisture. Without the heat sink 1 10, the heat dissipation from within the housing 100 to the outside because of the extremely poor thermal conductivity of the plastic wall 108 and also the glass plate, not shown here at the top very slowly.
- the glass plate in contact with the hot air inside can reach more than 60 degrees Celsius at the top cover of the housing.
- the current sensor and other low-voltage electronic components have a short life and a rapid performance deterioration when under high thermal stress.
- Heat removal may be accomplished using a heat-liquid filled heat pipe and circulating the liquid using a small electromechanical pump within the heat pipe.
- a small rotatable fan heat circulation within the limited air supply that fills the sealed plastic housing can be forced.
- Heat pipes together with a small electromechanical pump are not a cost effective solution and, in addition, due to moving or rotatable parts, a motor can have a reduced life and require frequent maintenance and also generate additional audible noise.
- the use of a small fan with rotatable blades is a somewhat more cost-effective solution that uniformly circulates the air inside the enclosure and avoids the creation of hotspots on the exterior of the glass panel / enclosure, Because of rotatable parts, the fan has a maximum life of 15,000 to 20,000 hours and may require maintenance, or otherwise, performance will degrade over time.
- an oval or annular, long heat sink 1 10 of aluminum is mounted on the given housing 100.
- the heat sink 1 10 is disposed on the upper part of the housing 100 both inside and outside of the approximately vertical plastic side walls 108. By the heat sink 1 10, the generated heat is brought out of the housing 100 out.
- the long oval aluminum heat sink 100 is mounted by a simple technique which leaves the plastic housing 100 tight to air, dust moisture.
- at least two Peltier elements 1 18 are mounted on the inner wall of the housing 100 for the rapid transfer of generated heat from the housing 100 out.
- the Peltier elements 1 18 may be, for example, square or rectangular. Here, the cold or colder side of each Peltier element 1 18 thermally coupled to the inner oval aluminum heat sink 1 12 and the heat absorbing element 1 12.
- each Peltier element 1 18 is thermally coupled to the outer annular or oval heat sink 1 14.
- the Peltier element 1 18 makes the inner ring 1 12 colder and causes a pumping of heat inside to the external environment through the outer annular / oval heat sink 1 14. So that the temperature of the outer heat sink 1 14 is not too far from ambient temperature, direct thermal contacts 16 are located at the far points. Since a Peltier element 1 18 represents a heat pump without rotating parts and therefore does not require maintenance, thus a noiseless cooling with extended life compared to a fan can be realized and a cheaper unit price can be achieved. This also supports forced convection of air within the housing 100 and therefore provides a uniform temperature. door rise of the housing 100 to prevent formation of hot spots similar to a rotatable fan.
- FIG. 2 is a perspective view of a vehicle charger 200 according to an embodiment of the present invention.
- the charger 200 may be referred to as a power electronics system.
- the charger 200 has a housing 100, which essentially corresponds to the housing in FIG. 1.
- the housing 100 is sealed airtight and moisture-proof by a glass plate 202 here.
- the glass plate 202 has strongly rounded corners.
- the housing 100 is thus substantially oval.
- the heat sink 1 10 surrounds the glass plate 202 annularly circumferentially. Here only the outer part 1 14 is visible.
- the interior of the housing 100 is not visible due to the closure by the glass plate 202.
- controls 204 for operating the charger 200 and a display element 206 are integrated.
- This technique can be applied to any power electronics system 200 enclosed in a sealed and air and moisture proof plastic housing 100.
- the shape of the housing 100 may be oval, cylindrical, cubic and even cuboid. Accordingly, the shapes of heat absorbers and heat sinks 1 10 can be changed or adapted.
- FIG. 3 is an illustration of a heat sink mounting solution according to an embodiment of the present invention.
- the fastening solution is illustrated by a partial sectional view of a housing 100, as shown for example in Figures 1 and 2.
- the heat sink is fastened by fastening clips 300, which penetrate the wall 108 of the housing 100.
- the mounting clips have at one end a flange 302, with which they rest against the wall 108.
- the fastening clips 300 have an internal thread 304 into which a screw is screwed when fastening the heat sink.
- FIG. 3 shows a mounting clip 300 having internal threads 304 for attaching the heat sink to the sidewalls 108.
