Cooler for electrical and/ or electronic components, linked to present cooling needs
View Patent ↗A cooler for electric and/or electronic components with a cooling body including a first flat outer wall and a second flat outer wall at a certain distance from each other and each creating a cooling area. There are cavities between the outer walls on the inside of the cooling body, creating a cooling channel connecting an inflow with an outflow through which a liquid cooling agent can flow. The cooling channel between inflow and outflow runs completely on the inside of the cooling body, and the cooling body is made up of a first part and a second part. The first part has the first outer wall, and at least the first part has a first set of indentations on a first inner wall opposite to the first outer wall, and wherein those indentations are closed off by the second part on the wall opposite of the first outer wall when the cooling body is assembled, thus creating the cooling channel. The course of the cooling channel and/or the arrangement of the cooling section or the cooling sections in the respective application case for which the cooler was designed is adapted to the cooling needs at the first outer wall and/or the second outer wall.
1. A cooler for electric or electronic components with a cooling body, said cooling body comprising a first flat outer wall and a second flat outer wall spaced a certain distance from each other and each wall creating a cooling area, wherein:
cavities, between said outer walls, inside of said cooling body, form a cooling channel, said cooling channel connecting an inflow with an outflow through which a liquid cooling agent can flow;
said cooling channel, between said inflow and said outflow, runs completely inside of said cooling body;
said cooling body comprises a first part and a second part;
said first part comprising said first outer wall and a first inner wall opposite of said first outer wall;
at least said first part comprising a first set of indentations in said first inner wall to therein form said cavities, wherein said first set of indentations are closed off by said second part when said cooling body is assembled, thus forming said cooling channel,
wherein said cooling channel is routed along a course that provides for cooling needs for at least one of said first outer wall or said second outer wall,
wherein screw bolts are provided for connecting said first and second parts to each other, wherein said screw bolts each comprise a shaft with an outer thread and a head that protrudes radially over said shaft and has a plane front side on an axial outside, wherein said shaft of each screw bolt penetrates an opening passage that is created in said first part and that acts together with an inside thread that is created flush with an opening passage in said second part, and wherein said head of each screw bolt is sunk in a depression surrounding said opening passage.
2. A cooler according to claim 1 , wherein several recesses are created on said head of at least one screw bolt on a radial outside, and wherein said recesses are used to screw in said screw bolt.
3. A cooler for electric or electronic components with a cooling body, said cooling body comprising a first flat outer wall and a second flat outer wail spaced a certain distance from each other and each wall creating a cooling area, wherein:
cavities, between said outer walls, on said inside of said cooling body, form a cooling channel, said cooling channel connecting an inflow with an outflow through which a liquid cooling agent can flow;
said cooling channel, between said inflow and said outflow, runs completely inside of said cooling body;
said cooling body comprises a first part and a second part;
said first part comprising said first outer wall and a first inner wall opposite of said first outer wall;
at least said first part comprising a first set of indentations in said first inner wall to therein form said cavities, wherein said first set of indentations are closed off by said second part when said cooling body is assembled, thus forming said cooling channel,
wherein said cooling channel is routed along a course that provides for cooling needs for at least one of said first outer wall or said second outer wall; and
a screw bolt connects said first part to said second part,
wherein said screw bolt comprises a head, a shaft and having an outside thread, and an inside thread that is arranged coaxially to said outside thread, and wherein said inside thread is open on at least one of (a) an axial front of said head, or (b) an axial end of said shaft.
4. A cooler according to claim 1 , wherein said first and second parts are glued to each other on inner contact surfaces.
5. A cooler according to claim 4 , wherein said inner walls have a surface roughness.
6. A cooling body for electric or electronic components, comprising:
a first part having a first inner wall that includes a channel;
a second part having a second inner wall situated against said first inner wall;
an inflow through which a cooling agent enters said channel; and
an outflow through which said cooling agent exists said channel,
wherein said channel provides relatively more cooling to said first zone of said cooling body as compared to a second zone of said cooling body, and
wherein said channel, in said first zone, includes a first partial channel and a second partial channel.
7. The cooling body of claim 6 , wherein said first partial channel and said second partial channel are parallel to one another.
8. The cooling body of claim 6 , wherein said first partial channel and said second partial channel are parallel to one another in a direction of a flow of said cooling agent.
9. The cooling body of claim 6 , wherein said channel does not traverse through said second zone.
10. The cooling body of claim 6 , wherein said channel is configured as a single channel in said second zone.
