Vapor chamber for cooling an electronic component, electronic arrangement, and method for manufacturing the vapor chamber

An electronic arrangement comprising:

• an electronic component, which generates heat while being operated;
• and
• a vapor chamber, the vapor chamber comprising:
• a bottom cover for receiving waste heat from the electronic component;
• a top cover, which is arranged on the bottom cover, wherein the bottom cover and the top cover are formed such that a vapor cavity for accommodating a liquid is formed between the bottom cover and the top cover;
• a crate element for providing mechanical strength to the vapor chamber, wherein the crate element has at least one compartment, which is formed by at least three side panels being connected to each other and extending from the bottom cover to the top cover, and a top recess facing the top cover and a bottom recess facing the bottom cover;
• and
• at least one porous pillar for transferring the liquid from the top cover to the bottom cover, wherein the porous pillar is arranged in the compartment and extends from the bottom cover through the bottom recess and the top recess to the top cover
• wherein the bottom cover of the vapor chamber is in thermal contact with the electronic component for cooling the electronic component and wherein the top cover of the vapor chamber is arranged facing away from the electronic component.

A method for manufacturing a vapor chamber for cooling an electronic component, the method comprising:

• providing a bottom cover for receiving waste heat from the electronic component;
• forming a crate element for providing mechanical strength to the vapor chamber on the bottom cover by additive manufacturing using a first energy input, wherein the crate element has at least one compartment, which is formed by at least three side panels connected to each other and which has a top recess and a bottom recess, which faces the bottom cover;
• and
• forming at least one porous pillar on the bottom cover in the compartment by additive manufacturing using a second energy input, wherein the first energy input is greater than the second energy input;
• and
• providing a top cover on the bottom cover, the crate element, and the porous pillar such that a vapor cavity for accommodating a liquid is formed between the bottom cover and the top cover, that the crate element and the porous pillar are arranged in the vapor cavity, and that the compartment and the porous pillar extend from the bottom cover to the top cover, with the top recess of the compartment facing the top cover.
