Definitions

  • the invention relates to a temperature regulation system for the interior of an automobile/motor vehicle and, in particular, to a cooling system for the interior of a parked vehicle.
  • thermoelectric modules are solid-state devices (no moving parts) that convert electrical energy into a temperature gradient known as the “Peltier effect” or convert thermal energy from a temperature gradient into electrical energy, the “Seebeck effect”.
  • thermoelectric(TE) modules used as thermoelectric generators are rather inefficient, they may be used as thermocouples for temperature measurements. That is the thermoelectric module, or Peltier element, can function as a heat pump. When the appropriate power is applied from a battery or another DC source, one side of the element will become cold while the other will become hot. (Reversing the polarity through the element will make the cold side hot and hot side, cold.) This provides Peltier elements to be very useful for heating, cooling and temperature stabilisation.
  • the Peltier element will absorb heat on the “cold side” and eject it out the “hot side” to a heat sink.
  • the heat sink In addition to the heat being removed from the object being cooled, the heat sink must be capable of dissipating the electrical power applied to the element, which also exists through its hot side.
  • the resistive or “Joule heat” created is proportional to the square of the current applied. With Peltier elements, this is not the case because the heat created is actually proportional to the current since the flow of current is working in two directions (the Peltier effect).
  • the total heat ejected by the Peltier element is the sum of the current times the voltage plus the heat being pumped through the cold side.
  • the cooler the hot side of the Peltier element the cooler the cold side will be.
  • the hot side will begin ejecting this as heat to the heat sink causing it to rise in temperature.
  • the ability of the heat sink to dissipate this heat as well as the heat being pumped through the cold side will determine the actual operating temperature of the hot side and, thus, the cold side.
  • thermoelectric applications the most common type of heat sink used in thermoelectric applications is made from a thermally conductive material such as aluminum or copper with fins which are perpendicular to a base.
  • a heat sink alone is not able to remove a sufficient amount of heat by natural convection in order to keep the hot side at an acceptably low temperature.
  • a fan To help the heat sink remove heat on and around the heat sink fins, a fan must be attached which forces ambient air over the fins and exhausts the heat to ambient.
  • PV cells are photovoltaic (PV) cells which can convert sunlight directly into electricity.
  • PV cells are made of semiconductors, such as silicon.
  • PV cells have one or more electric fields which act to force electrons freed by light absorption to flow in a certain direction.
  • This flow of electrons is a current and, by placing metal contacts on the top and bottom of the PV cell, one can draw that current off to use externally.
  • This current along with the cell's voltage (which is a result of its built-in electric field or fields) defines the power that the solar cell can produce. Moreover, it is a direct current since the flow of electrons is in one direction.
  • the temperature regulation system consists of photovoltaic cells, a power supply, and an open ended mechanical unit having sides for supporting a heat pump.
  • the photovoltaic cells can be comprised of solar cells attached one to another for generating energy.
  • the solar cells can be connected to the power supply which controls the distribution of energy and the interaction between the system and the vehicle.
  • the power supply can also activate the heat pump, such as a Peltier element.
  • openings can be provided to accommodate one or more Peltier elements, having an inner surface and an outer surface. Each surface of a Peltier element can be attached to a heat sink, one providing the cold source and the other providing the hot source.
  • a main fan can be installed to thrust air across the cold surface (or hot surface, if the polarity is reversed) for passage through the opposite end and into the interior of the vehicle. Additional fans can be placed on top of the heat sinks to dissipate heat from the hot source (or cold source, if the polarity is reversed).
  • the power supply can be an electronic control unit, such as a printed circuit board, and the mechanical unit can be a tubular body.
  • FIG. 1 is a block diagram of the temperature regulation system.
  • FIG. 2 is the top of a perspective view of the tubular body.
  • FIG. 3 is a cross-sectional view of the tubular body.
  • the temperature regulation system is illustrated as a block diagram.
  • it is comprised of solar cells, 1 , connected to an electronic control unit, 2 , which distributes the electricity coming from the solar cells to the various parts of the mechanical unit, i.e. the two types of fans, 3 & 6 , and the stage one Peltier elements, 4 , when the automobile is parked.
  • a certain number of Peltier elements (for example, 2) works very well to lower the temperature, substantially below the outside temperature, of the interior of an automobile when it is parked.
  • the power coming from them is sufficient to activate approximately 50% to 60% of the elements' capacity.
  • the electronic control unit withdraws the extra needed electricity from the battery, 7 , for the supplementary energy for the stage 1 Peltier elements, 4 , and the activation of the stage 2 Peltier elements, 5 , to function at maximum capacity.
  • the electronic control unit also had a temperature regulator, ( FIG. 1, 8 ) to control the interior temperature, when the automobile is running, and a switch to turn off the system completely, when a sensor ( FIG. 1, 9 ) detected high levels of carbon monoxide.
  • the electronic control unit had a safety feature when the carbon monoxide sensor switched off the fans or when either heating or cooling the interior of the automobile was not a priority but yet a great deal of sunlight was prevalent. Under such circumstances, solar energy should be consumed one way or another because, if it is not, the stored energy in the solar cells coming from the sunlight would destroy them. In order to dissipate the unused energy, the electronic control unit re-directs this unused energy to charge the battery.
  • FIG. 2 is the top view of a perspective drawing of a specific design of the mechanical unit and FIG. 3 is a schematic drawing of the cross section of that design illustrating the inside of the unit.
  • the unit contains Peltier elements, 4 & 5 , two types of fans, 3 & 6 , heat sinks, 10 , and a carbon monoxide sensor, 9 . It is comprised of a tubular body (basically, a housing) with Peltier elements on one or either side integrated into the side wall(s). In the case of cooling, the hot side of the Peltier elements is on the outer side and the heat sinks lie on top of them.
  • the fans, 6 (only one fan is showing in FIG.
  • the heat sinks are attached to the top of the heat sinks in order to direct air along the outside of the housing, i.e. to remove the heat from the hot side and lower the temperature of the cold side.
  • the cold side of the Peltier elements is on the inside of the housing and also has heat sinks attached to them.
  • there is a major fan, 3 at one open end to direct air through the inside of the tubular body, i.e. to flush and expel the coldness out the opposite open end. Since the housing would be installed preferably in the front of the vehicle behind the grill and next to the radiator, or possibly any available space under the hood if there is no space in the very front, the open end is then attached simply to the ventilation system via a tube.
  • the solar cells would be placed in between the two panes of glass which make up the front or back windshield or alternatively in the sunroof windshield, if such exists.
  • an UV-resistant and heat-resistant plastic frame for two 2V solar cells was produced.
  • Six solar cells were connected in series to yield 12 volts and then 2 or 3 sets of six in parallel to generate just enough current for two, three or more Peltier elements, depending on the volume of the passenger compartment, needed to lower the interior temperature of the vehicle substantially below the exterior temperature. Since the frames were designed with a width of approximately 51 mm, they were placed along the top of the front windshield and/or the bottom of the back windshield with suction cups. These two positions rendered the absorption of sufficient solar energy and yet had little or no affect on obscuring the visibility of the driver.
