摘要：
Cooling element 10, suitable for a vacuum pump, comprising a base element 12 which defines an internal void, flowpath or space, fed with a coolant via an inlet 14. The coolant passes through the internal void and out of outlet 16; that is the inlet and outlet are in fluid communication with the void. The base element is connectable to a housing of a pump. Preferably at least one of the upper 30 and lower 24 surfaces of the base element are corrugated, i.e. formed with grooves or ridges 32 (36, fig.3) which are perpendicular to the flow 34. The lower surface, to place adjacent to a pump, is preferably less than 2mm thick and can be made from stainless steel it can also be planar and lie parallel to the pump housing. Alternatively, the base element can be corrugated and enveloped in a connecting element forming a cooling block made of aluminium (38, fig.3). The base element may be made by additive manufacturing, 3D printing, and formed in a single piece with inlet and outlet attached by welding or brazing. A plaited wire mesh turbulator (fig.4) may be placed in a tubular void to ensure turbulent flow.

CLAIMS
1. Cooling element for a vacuum pump, comprising
a base element, wherein by the base element an internal void is defined,
an inlet connected to the base element and in fluid connection with the
void and
an outlet connected to the base element and in fluid connection with the
void such that a coolant can flow from the inlet through the void to the
outlet to dissipate heat,
wherein the base element is connectable to a housing of the vacuum
pump.
2. Cooling element according to claim 1 characterized in that the void is
tubular.
3. Cooling element according to claim 1 characterized in that the void has a
flat shape.
4, Cooling element according to any of claims 1 to 3, characterized in that
the base element has a flat shape.
5. Cooling element according to any of claims 1 to 4, characterized in that
the base element comprises a bottom surface to be directly attached to
the surface of the housing of the vacuum pump.
6. Cooling element according to claim 5, characterized in that the material
thickness between the bottom surface and the void is less than 3mm,
preferably less than 2mm and more preferably less than 1mm.
7. Cooling element according to any of claims 1 to 6, characterized in that
the internal void comprises at least one corrugated surface to create tur-
bulent flow within the void.
8. Cooling element according to any of claims 1 to 7, characterized by a
turbulator element disposed within the void to create turbulent flow within
the void.
9. Cooling element according to any of claims 1 to 8, characterized in that
the base element is one piece.
10. Cooling element according to any of claims 1 to 9, characterized in that
the base element is fabricated by 3D printing.
11. Cooling element according to any of claims 1 to 10, characterized in that
the base element is surrounded by a connecting element, preferably
made from aluminum, wherein the connecting element is directly con-
nected to the housing of the vacuum pump.
12. Cooling element according to any of claims 1 to 11, characterized in that
the base element is made of stainless steel.
13. Vacuum pump comprising a housing and a cooling element according to
any of claims 1 to 12 connected to the housing.
