Abstract
Claims
1. A two-phase cold plate, comprising: a base plate having a plurality of first fin groups, the plurality of first fin groups having a plurality of first peaks; and a top cover disposed on the base plate, the top cover having a plurality of second fin groups, the plurality of second fin groups having a plurality of second peaks; wherein, The plurality of first fin groups and the plurality of second fin groups have different orientations. When the top cover is combined with the bottom plate, the plurality of first wave crests and the plurality of second wave crests make staggered contact to form a plurality of contact points.
2. The two-phase cold plate as described in claim 1, wherein, The plurality of first fin groups have a plurality of first troughs, and the plurality of second fin groups have a plurality of second troughs.
3. The two-phase cold plate as described in claim 2, wherein, Each of the plurality of first troughs defines a first base angle for the liquid fluid to converge and evaporate.
4. The two-phase cold plate as described in claim 3, wherein, Each of the plurality of second troughs defines a second base angle for the gaseous fluid to converge.
5. The two-phase cold plate as described in claim 4, wherein, The liquid fluid gathers in the plurality of first troughs and evaporates into a gaseous state upon heating. The gaseous fluid rises into the plurality of second troughs and condenses into a liquid state. The liquid fluid flows from the plurality of second troughs to the plurality of second peaks and flows back to the plurality of first peaks of the base plate via the plurality of contact points.
6. The two-phase cold plate as described in claim 2, wherein, The plurality of first fin groups are composed of a plurality of first fins and a plurality of second fins, and the plurality of second fin groups are composed of a plurality of third fins and a plurality of fourth fins. The plurality of first fins and the plurality of second fins are arranged along a first tilting direction and a second tilting direction, respectively, according to a first center reference line, from a first side to a second side of the two-phase cold plate. The plurality of third fins and the plurality of fourth fins are arranged along the first tilting direction and the second tilting direction, respectively, according to a second center reference line, from the second side to the first side of the two-phase cold plate.
7. The two-phase cold plate as described in claim 6, wherein, Each of the plurality of first peaks and each of the plurality of first troughs has a first included angle and a second included angle, respectively, and each of the plurality of second peaks and each of the plurality of second troughs has a third included angle and a fourth included angle, respectively.
8. The two-phase cold plate as described in claim 7, wherein, The first included angle may be the same as or different from the second included angle, and the third included angle may be the same as or different from the fourth included angle.
9. The two-phase cold plate as described in claim 1, wherein, The top cover further includes a water inlet, a water outlet, a water inlet channel, and a water outlet channel. A fluid enters the water inlet channel through the water inlet and is guided through the water inlet channel to the plurality of first fin groups for heat exchange.
10. The two-phase cold plate as described in claim 1, wherein, When the top cover is combined with the bottom plate, a sealed chamber is defined, in which the plurality of first fin groups and the plurality of second fin groups are housed.
