Abstract

A fluid heat exchanger includes: a base, a heat pipe including an evaporator portion thermally coupled to the base and a condenser portion; a coolant block portion thermally coupled to the condenser portion of the heat pipe, the coolant block portion including a liquid tight passage extending from a passage inlet to a passage outlet.

Claims

1. A fluid heat exchanger comprising:

a base, a heat pipe including an evaporator portion thermally coupled to the base and a condenser portion;

a coolant block portion thermally coupled to the condenser portion of the heat pipe, the coolant block portion including a liquid tight passage extending from a passage inlet to a passage outlet.

2. The fluid heat exchanger of claim 1 wherein the passage inlet is formed as a barb.

3. The fluid heat exchanger of claim 1 wherein the passage outlet is formed as a barb.

4. The fluid heat exchanger of claim 1 further comprising internal dividers defining the liquid tight passage.

5. The fluid heat exchanger of claim 1 wherein the heat pipe includes an elongate return thermally coupled to the coolant block.

6. The fluid heat exchanger of claim 1 wherein the coolant block portion includes an upper portion and a clamping portion and the condenser portion of the heat pipe is clamped between the upper portion and the clamping portion.

7. A cooling system for a heat-generating component, the cooling system comprising:

a fluid heat exchanger including a base, a heat pipe including an evaporator portion thermally coupled to the base and a condenser portion;

a coolant block portion thermally coupled to the condenser portion of the heat pipe, the coolant block portion including a liquid tight passage extending from a passage inlet to a passage outlet.

8. The cooling system of claim 7 further comprising a liquid coolant inlet tube connectable at the passage inlet.

9. The cooling system of claim 7 further comprising a liquid coolant outlet tube connectable at the passage outlet.

10. The cooling system of claim 7 further comprising a liquid coolant circuit in which the fluid heat exchanger is connected.

11. The cooling system of claim 10 wherein the liquid coolant circuit includes a liquid coolant inlet tube connected at the passage inlet, a liquid coolant outlet tube connected at the passage outlet and a heat sink connected between the liquid coolant outlet tube and the liquid coolant outlet tube.

12. The cooling system of claim 7 wherein the passage inlet is formed as a barb.

13. The cooling system of claim 7 wherein the passage outlet is formed as a barb.

14. The cooling system of claim 7 further comprising internal dividers defining the liquid tight passage.

15. The cooling system of claim 7 wherein the heat pipe includes an elongate return thermally coupled to the coolant block.

16. The cooling system of claim 7 wherein the coolant block portion includes an upper portion and a clamping portion and the condenser portion of the heat pipe is clamped between the upper portion and the clamping portion.
