At the in 1 the situation is the component 20 of a vehicle 1 as a soche with her top 20a and their bottom 20b in isolated form. From the bottom 20b It will be in the direction of the arrow 20c a preassembled arrangement for a heat pipe assembly 50 or for a heat pipe to the bottom 20b in the area of a section 21 the component 20 approximated.

The preassembled arrangement for the heat pipe arrangement 50 consists of a convex-concave housing area 52 with an inside 52a which is a wick material 59 - 1 having a cavity 59 - 2 encloses, which later as a steam chamber of the trainee heat pipe arrangement 50 serves.

In the transition to the in 2 shown state occurs with the approach 20c to the bottom 20b and after touching, forming a connection 57 between the inside 52a in a border section thereof and the bottom 20b of the section 21 the component 20 of the vehicle 1 , Through the connection 57 If necessary, also a seal, in connection with an evacuation of the interior 59 - 2 and a subsequent filling with a heat transfer material, for example with water.

The area 52 ' as a housing area 52 is accordingly as a second area or second housing portion of the heat pipe assembly 50 construed.

At the in 2 As shown, the second housing portion 52 is operable to form, for example, the area of a heat source 53 or a coupling to a heat source and thus acts as an evaporator 55 for the inside of the housing thus formed 58 absorbed heat transfer medium in order to evaporate this and transport by convection on the opposite side, ie in the direction of the first housing portion 51 to.

This first housing area 51 passing through the section 21 the component 20 of the vehicle 1 So, in particular, is formed by a body component, acts as a heat sink or as a thermal coupling to a heat sink and thus forms the function of a capacitor from, in the area, in particular in the wick material 59 - 1 and at the bottom 20b of the section 21 the component 20 on the opposite side in the evaporator area 55 evaporated heat transfer medium is condensed and thus liquefied, and then on the capillarity of the wick material 59 - 1 , which is also referred to as Wick, again to the evaporator area 55 to be transported.

3 shows a perspective side view of the application of the inventive concept in a hood 3 as inventively designed vehicle component 20 ,

The hood 3 is understood here as a component 20 or body component 20 a vehicle designed according to the invention 1 ,

The hood 3 has recesses as a sheet metal construct 22 and reinforcements surrounding these pits 23 on. In some of the wells 22 are insulation elements 24 designed to serve the sound insulation and to dampen engine noise.

At least some of the wells 22 can be used as an alternative to insulation 24 or in addition to this according to the invention with corresponding heat pipe assemblies 50 be or be trained. In the in 3 situation shown are the bottom on the left and right side of the hood 3 provided wells 22 , which the pivoting range of the hood 3 and thus the pivot axis 3 - 1 come closest, each with a inventively designed heat pipe assembly 50 educated.

4 shows a schematic and sectional side view of an inventive vehicle 1 in which the hood 3 as a body component 20 as inventively designed integrated heat pipe assembly 50 acts or such a heat pipe assembly 50 integrated wears.

In 4 the heat supply takes place 61 via a heat exchanger 7 or heat exchanger, which via lines 6 - 1 a through a pump 6 - 2 powered coolant 8th from a motor 5 - Also conceivable are other units, for example, battery modules or the like - with high temperature to the bottom or outside 52b of the housing 58 the heat pipe arrangement 50 promotes through the outside of the heat exchanger 7 ,

The heat pipe arrangement 50 itself transfers heat to the bottom via the heatpipe concept in the manner already described above 20b the hood 3 , construed as a component 20 of the vehicle 1 , from where, conveyed by the airstream as cooling air 63 , the heat dissipation 62 from the top 20 a the hood 3 into the environment.

As further components of the vehicle according to the invention are still the wheels 4 , the bodywork 2 in total and the windshield 9 shown.

These and other features and characteristics of the present invention will be further elucidated with reference to the following statements:

In particular, the present invention provides a heat pipe 50 , on a bonnet 3 or other body parts - construed as a component 20 of a vehicle 1 - Is integrated.

A classic heat pipe or vapor chamber (vapor chamber) - conceived as a heat pipe arrangement according to the invention 50 - For example, consists of a copper shell. The interior is evacuated and divided into two zones, namely an area for the liquid medium and an area for the evaporated medium. The transport of the liquid medium to the hotspots is done by capillary forces of a suitably selected wick material 59 - 1 , The vaporous medium moves in the remaining cavity as a steam chamber 59 - 2 to the condensation points, so a heat sink area 54 that also serves as a capacitor area 56 acts. In the area for the steam can also be a support grid that the steam chamber 59 - 2 supported against the negative pressure. At the condensation points, the vapor is condensed back again and via capillary forces of the wick material 59 - 1 on again to the evaporator sites, so a heat source area 53 , which as the evaporator area 55 acts, transports.

Copper as a material for the shell and the internal structures is used because of the good conductivity and in this case mainly because of the good resistance to the high purity water used as a transport medium. However, it is not necessary for the physical function of the steam chamber. There are also other materials conceivable. The prerequisite is that the material used is resistant to the medium used and does not influence and worsen the vacuum in the steam chamber by outgassing.

In the invention, the principle of the heat pipe arrangement 50 or steam chamber 59 - 2 for example for exterior body parts 20 and especially with well-inflated parts, such as the hood 3 applied as a means of heat dissipation to the environment.

In particular, the implementation using the already existing functionally necessary components is advantageous. These are mainly on the insides 20b of body panels 21 attached reinforcing or stiffening components 23 as well as elements 24 for insulation, anti-drone elements, soundproofing and thermal insulation.

3 shows a hood as a component 20 of a vehicle 1 , with stiffening components 23 and soundproofing mats 24 ,

In the area between bodywork 2 and stiffening components 23 - but also otherwise - can be a heat pipe arrangement 50 integrated into the component 20 of the vehicle 1 being constructed.

This must be on the respective insides 20b the sheets 20 . 21 the wick or wick material 59 - 1 be applied for the transport of the liquid phase of the transport medium. After connecting the outer skin with the stiffening components 23 the forming intermediate space must be considered a steam room or steam chamber 59 - 2 be evacuated and filled with the required amount of the transport medium, for example water.

This reaction according to the invention is particularly suitable for heat generously on a sheet metal component as a vehicle component 20 to distribute.

Between the body 2 and the soft components, such as a sound insulation 24 , can be a heat pipe arrangement 50 be built, which with flexible and thin heat pipe arrangements 50 or steam chambers 59 - 2 are formed of metal foils with an interposed support structure in the form of copper grids.

Also, embodiments of pure polymer materials are conceivable. The thickness of the heat pipe assembly 50 can be in the range of a few millimeters and can be reduced to 0.1 mm, for example.

It is conceivable that the outside - that is a first area 51 ' or first housing area 51 - A inventively designed heat pipe assembly 50 from the body panel as a vehicle component 20 is formed. The body sheet 20 must be coated accordingly to corrosion by the water in the heat pipe assembly 50 to prevent. The inside of the heat pipe assembly 50 is formed by the attached functional parts. The space between the two layers - ie the actual steam chamber 59 - 2 - Is thereby introduced by grid and structures of the wick material 59 - 1 ensured. After all the layers have been applied and sealed together, as in the first case, the gap must be evacuated and filled with the transport medium or heat transfer medium, for example with water.

This implementation is particularly suitable to ensure a uniform and areal distribution of heat on the body panel.
