Definitions

  • the invention relates to a device for thermal conditioning of a component by means of direct or indirect body contact regardless of a position and movement of the component in space and a method for thermal conditioning of a component by means of direct or indirect body contact regardless of a position and movement of the component in space.
  • a defined heat dissipation or supply is often required to stabilize components within their operating temperature and thus the entire electrical circuit.
  • heat removal is only possible if the temperature of a heat-absorbing sink is lower than the temperature of a heat-emitting source.
  • the regulation of the temperature of components for example by using fans, technically simple and effective implement.
  • a challenge represents the heat dissipation of components in extraterrestrial applications.
  • thermally well insulating vacuum heat pipes or closed liquid cooling can be used to transport heat from a heat source to a heat sink.
  • the heat sink can be realized for example by radiation via radiators to space.
  • thermally conditioning is to use open evaporators which supply the heat to a container in which a liquid vaporizes at the vapor pressure corresponding to its temperature and releases the vapor to the environment.
  • Another option for thermal conditioning is provided by thermochemical heat storage. Exothermic or endothermic processes are used to generate or absorb heat.
  • DE102010047371A1 is a self-cooling beer keg shown as an example of a thermochemical heat storage in which desorbs a working fluid and dissipates heat.
  • the object of the invention is to provide a device for thermal conditioning of a component by means of direct or indirect body contact regardless of a position and movement of the component in space, which eliminates the aforementioned disadvantages.

  • the device has a device for applying the derivative with a negative pressure against an internal pressure of the reaction vessel.
  • the device may extract or supply heat directly or indirectly to one or more components via the interface.
  • it is independent of external physical conditions and can therefore also be used, among other things, in vacuum and / or weightless conditions as well as in accelerated movements such as occur in automobiles, aircraft and spacecraft.
  • a constant holding of an operating temperature is possible regardless of external conditions.
  • it is significantly lighter weight or lighter with the same cooling performance.
  • a supply line is thus also understood to mean a container opening which is closed, for example, after the supply.
  • the supply line of the reaction container preferably extends from a storage container which provides the sorptive.
  • the reaction vessel can be refilled.
  • the refilling can be done in such a way that generates adsorbing energy when taking the sorbent of the sorbent, which can then be used for heating.
  • the reaction vessel has a heat conduction structure arranged in its interior. Due to the heat conduction structure, the heat of the component can be passed homogeneously and quickly into the reaction vessel via the interface (cooling function). Likewise, the heat-conducting structure allows a fast and uniform removal of the resulting in the reaction vessel Heat to a component (heating function).
  • the heat-conducting structure is preferably designed in the form of a rib structure or a foam. This can for example consist of metal such as aluminum or an aluminum alloy or another good heat-conducting material.

  • the supply line has a first valve device for opening and controlling the supply line.
  • the first valve device may, for example, in the form of a metering valve, a Stopcock and the like. This allows you to control and regulate the feeding of the sorptive.
  • a second valve means for opening and controlling the discharge is arranged in the discharge.
  • the second valve device for example in the form of a metering valve, a stopcock and the like. This measure makes it possible to control both the negative pressure in the derivative and the derivation of the desorptive and regulate.

  • the temperature of the component can be influenced by a supply line of the sorbent in and / or a derivative of the desorptive from the reaction vessel.
  • Vacuum can be generated independently of the external physical conditions, so that the thermal conditioning can take place independently of external influences and the orientation of the component in space.
  • the desorption of the desorptive from the reaction vessel is effected by a pressure difference between the reaction vessel and the discharge.
  • the pressure difference can be done either by a vacuum pump or by taking advantage of a possible low ambient pressure. Especially in extraterrestrial applications weight and cost can be saved.
  • the desorptive temperature and / or pressure and / or time-controlled derived from the reaction vessel allows complete derivation-side automation of the thermal conditioning of the component.
  • the sorptive is supplied to the reaction vessel as a function of at least one operating parameter. This measure allows a complete supply-side automation of the thermal conditioning of the component.
  • the desorptive is condensed to the sorptive and fed back as sorptive into the reservoir.
  • a closed circuit is created, which for example provides advantages in long-term operation, since no losses of the sorptive and / or desorptive occur.
  • the temperature or the pressure in the reaction vessel may be the control variables
  • the valve devices are used in particular for regulating the pressure, which thus act as an actuator or actuators. It is also suitable the ability to specify, for example, a desired internal pressure in the reaction vessel, which is controlled automatically by the valve devices. In this case, a measured actual pressure can be compared with the desired pressure and readjusted accordingly via the valve device.
