Embodiment Construction

[0036] The terms "downstream" and "upstream" in this specification are defined with respect to the general direction of fluid flow in the loop.

[0037] see figure 1 , the capillary-pumped two-phase fluid loop 2 of the heat transfer system according to the present invention includes an evaporator 4 that extracts heat from a heat source 6 to be cooled, and a condenser 8 that returns the heat to the cooling Source 10. For example, the heat source is an item in heat-dissipating electronics placed on the machine. For example, the cooling source is a heat sink placed on the outer surface of the machine.

[0038] The fluid circuit 2 also comprises a vapor pipe 12 connecting the outlet 14 of the evaporator 4 to the inlet 16 of the condenser 8 , and a liquid pipe 18 connecting the outlet 20 of the condenser 8 to the inlet 22 of the evaporator 4 .

[0039] The steam pipe 12 may include one or more bypass branches (not shown in the figures). Likewise, the liquid line 18 may comprise...

Abstract

The invention relates to a heat transfer system comprising one main capillary pumped diphasic fluid loop and a secondary capillary pumped diphasic fluid loop suitable for cooling at least one hot source. The main fluid loop and the secondary fluid loop comprising one evaporator, a vapour pipe capable of conveying the cooling fluid in the vapour state from the evaporator to a condenser, a condenser and a liquid pipe capable of conveying the cooling fluid in the liquid state from the condenser to the evaporator so that the cooling fluid of the main fluid loop is in heat exchange with the cooling fluid of the secondary fluid loop.

Description

technical field [0001] The present invention relates to a heat transfer system comprising at least two capillary pumped two-phase fluid loops for cooling at least one heat source. Background technique [0002] A capillary-pumped two-phase fluid loop (often referred to simply as a "fluid loop" due to language misuse) is a system that transfers thermal energy from a hot source to a cold source by using capillary tubes to drive pressure, and (Liquid-gas) phase transitions are used as a means of transferring energy. [0003] Such fluid circuits typically include an evaporator for extracting heat from a heat source and a condenser for returning that heat to a heat sink. The evaporator and condenser are connected by a tube called a liquid line and a tube called a vapor line, in which a cooling fluid, mostly liquid, In the tube, the same cooling fluid, mostly in gaseous state, circulates in its hot part. The various tubes are in the form of tube elements, usually made of metal w...
