Definitions

  • the present invention relates to a heater, especially a heater for a car interior compartment.
  • the cooling water of the car engine can not absorb enough heat from the engine at the very beginning right after the car is activated, and thus the temperature of the cooling water is not high enough to be used as heating of the interior compartment of the car.
  • an interior compartment heater is installed in the car to provide the warm air right after the car is activated, thereby enhancing comfort for the driver.
  • the conventional heater used in the interior compartment of the car mainly includes a first base, a second base, and a heating module connected between the first base and the second base.
  • the heating module includes a positive temperature coefficient (PTC) heating component, a pair of electrode plates stuck both sides of the PTC heating component, and a pair of thermal diffusion body sticking to each of the electrode plates respectively.
  • the control circuit of the heater is provided inside the first base.
  • the conventional car interior compartment heater has the following drawbacks.
  • the well-arranged PTC heating components, each electrode plates, and each thermal diffusion body are clipped by the clamp of machines to be assembled into the first base and the second base, which means the assembling of the heater should depend on the clamp of the machines, and thus causes inconvenience of the assembling.
  • the control circuit is short circuited or damaged, the first base should be taken off from the heater to fix the control circuit.
  • the PTC heating components, each electrode plates, and each thermal diffusion body are disassembled because of lacking the clipping by the first base, and the heater is not easy to be reassembled back to the original condition after the control circuit is fixed.
  • the contact surfaces between each electrode plate and the PTC heating components are not smooth and not compactly sticking to the electrode plate and the PTC heating components, so the efficiency of the power conduction from each electrode plate to the PTC heating components is not good enough, thereby further resulting in bad heat generating efficiency of the PTC heating components. And also, the efficiency of conducting the heat generated by the PTC heating components to each electrode plate is not good enough as well.
  • each electrode plate and the insulation thermal tape are not smooth, and the insulation thermal tape is not compactly stuck to each electrode plate. Moreover, the heat conduction effect of the insulation thermal tape is not good as well, and thus decreases the effect of heat conduction from each electrode plate to each thermal diffusion body, thereby lowering the heat generating efficiency of the heater.
  • EP 2 023 056 describes a binding process for an air heater and structure thereof, in particular a heater having application in air, in which various modularized prefabricated units are used to assemble and enable subsequent binding and rapid production of the heater.
  • An electric conduction test is simultaneously implemented during the binding process, which enables accelerating the speed of solidification of a binding material and avoids a baking energy load. It is able to withstand a relatively large assembly clamping pressure during the binding process, and achieves a substantially large secure mechanical force fit between the components after completing assembly that provides good conducting physical properties.
  • This document shows in figure 3 that there are PTC heating components included in the heating module.
  • the heating module is sandwiched between a pair of electrodes, which is connected by a binding material.
  • On each side of the electrode plates there are heat exchanger units, wherein between the electrodes and the heat exchanging unit there is an insulation thermal conduction layer.
  • the present invention provides a heater for a car interior compartment.
  • the present invention connects each electrode plate to the PTC heating components by a thermal conduction glue, thereby improving the efficiency of conducting the electricity from each electrode plate to the PTC heating components, and the heating effect of the PTC heating components can be improved accordingly.
  • the present invention also provides a heater for a car interior compartment, and each electrode plate and each thermal diffusion body are connected with an insulation thermal conduction glue to prevent the electricity leakage by avoiding the electricity conducting from each electrode plate to each thermal diffusion body.
  • a heater for a car interior compartment includes a framework and a heating module.
  • the framework includes a first base and a second base arranged in interval with the first base.
  • the heating module is provided between the first base and the second base.
  • the heating module includes a PTC heating component, a thermal conduction glue, a pair of electrode plate, a insulation thermal conduction glue, and a pair of thermal diffusion body.
  • the electrode plate is stuck to both sides of the PTC heating component by the thermal conduction glue.
  • Each thermal diffusion body connects each electrode plate in an insulation way by the insulation thermal conduction glue.
  • the present invention has the advantages as follows.
  • Second, the control circuit can be repaired from the opening trough of the first base without taking off the first base from the heater, thereby saving the time of repairing and maintaining.
  • Fourth, a side of the sheet metal can be formed with a plurality of long strip shape dents to increase the air contact area for each fin to improve the heat exchanging effect, thereby improving the heating effect of the heater as well.
  • the thickness of the fins, as well as the material cost can also be reduced.
