Abstract
The utility model relates to a flow channel structure of a heat collector of a liquid cooled radiator. An upper cover seals and covers a heat collector sheet and forms a closed containing chamber with the heat collector sheet. The closed containing chamber is divided into different partition areas by a partition sheet. The same sides of the two adjacent partition areas are communicated to form a labyrinth path. A plurality of parallel fins and a plurality of parallel flow channels are arranged in the partition areas. By the structure, the contact area of liquid in a heat radiator and flow channels is raised, and the liquid flows in the flow channels. The flow speed of the liquid can be buffered because of interference, and therefore, heat absorbed by the liquid can be increased. The heat collection effect of the heat collector sheet is raised effectively, and the purpose of improving the use benefit of the entire heat radiator is achieved.

Technical field
The utility model is the heat collector flow passage structure about a kind of liquid-cooling heat radiator, refers to a kind of heat collector flow passage structure that is applicable to the liquid-cooling heat radiator of computer apparatus especially.
Background technology
In general computer apparatus, its inner main heat-generating electronic elements is its CPU (CPU), and is effectively the heat that it produced to be shed, and then must organize and be provided with a heat abstractor.
See also the stereogram of Fig. 1 for known water-cooled power converter, it mainly includes a thermal-arrest unit 91, a water tank 92 and a heat-sink unit 93, wherein thermal-arrest unit 91 is in order to collect the above-mentioned CPU heats that heat-generating electronic elements produced such as (CPU), and via heat pipe 94 heat is brought to heat-sink unit 93 and shed, water tank 92 then is in order to store the employed liquid medium of integral heat dissipation means.
See also the three-dimensional exploded view of Fig. 2 for known thermal-arrest unit, wherein show a heat collector sheet 911, a pad 912, reach a loam cake 913, and on heat collector sheet 911, be concaved with a flow channel for liquids 910, yet, the design that this flow channel for liquids 910 is a single runner, forward flow, that is liquid is when flowing in this flow channel for liquids 910, the contact area of liquid and flow channel for liquids 910 only limits to the two side of flow channel for liquids 910, and therefore liquid only can absorb the heat of flow channel for liquids 910 two sides, and can't obtain a larger area endothermic effect.In addition, liquid is to be in the state that constantly flows in flow channel for liquids 910, therefore see it in a certain ad-hoc location, the liquid of this ad-hoc location also can't stop the heat of time too of a specified duration with effective absorption heat collector sheet 911, so the purpose and the effect of thermal-arrest still can't effectively be reached in aforementioned known thermal-arrest unit 91, are not very good.
The utility model content
Main purpose of the present utility model is to provide a kind of heat collector flow passage structure of liquid-cooling heat radiator, promoting the Heat-collecting effect of heat collector sheet, and by to improve the utilization benefit of integral heat dissipation means.
For achieving the above object, the heat collector flow passage structure of liquid-cooling heat radiator of the present utility model mainly includes a heat collector sheet, reaches a loam cake, wherein this loam cake closing cap on this heat collector sheet and and this heat collector sheet between form an airtight room, and this loam cake and offer two openings and be communicated with respectively between extraneous and this airtight room;
In this airtight room and be provided with at least one shim, and this at least one shim should be separated into two compartment district at least by airtight room, adjacent two compartment district also is connected to form a labyrinth channel in same side each other, and be provided with plurality of parallel fin, and plurality of parallel runner in each marker space, the front end of this labyrinth channel, and the rear end corresponding respectively and be communicated to this two opening.
The heat collector flow passage structure of described liquid-cooling heat radiator, this heat collector sheet also includes a upper surface, and this at least one shim is convexly set on this upper surface.
The heat collector flow passage structure of described liquid-cooling heat radiator, these parallel fins are convexly set on this upper surface.
The heat collector flow passage structure of described liquid-cooling heat radiator, this heat collector sheet also includes a lower surface, and this lower surface is formed with its correspondence of thermal-arrest district and is adjacent to a heat-generating electronic elements.
The heat collector flow passage structure of described liquid-cooling heat radiator, this heat collector sheet is a copper sheet.
From the above, by the design of plurality of parallel fin and plurality of parallel runner, can increase the interior liquid of heat abstractor and the contact area of runner, and can increase the heat that liquid absorbs.In addition, by the parallel fins in formed labyrinth channel in marker space and the marker space and the design of parallel fluid channels, when the interior liquid of heat abstractor is flowed in runner, slow down its flow velocity because of being interfered, in a certain ad-hoc location, the liquid of this ad-hoc location can have the more time with the absorption heat, that is liquid can increase the heat that it absorbs.So the utility model can effectively promote the Heat-collecting effect of heat collector sheet really as can be known, and can improve the utilization benefit of integral heat dissipation means.
