Description
Technical field
The utility model relates to a kind of radiator, especially a kind of microchannel heat sink.
Background technique
Microchannel heat sink has many advantages, such as that heat exchange efficiency is high, working medium dosage is few compared with traditional heat sinks.With people
Higher and higher to protection environment and energy saving requirement, microchannel heat sink will be obtained by the advantage of itself in many industries
To being widely used, such as air conditioner industry, automobile industry, chemical machinery industry, but existing micro-channel flat is connected to afflux
Pipe, used mode is usually: in the end insertion header of micro-channel flat, since header to be guaranteed and flat tube weld
When flat pipe hole do not blocked by solder flux, it is necessary to flat tube is inserted at position deeper in header, that is, flat tube protrudes into header
Length it is longer, and header inner space is limited, and it is horizontal that the inserting paragraph of micro-channel flat occupies natively limited header
A big chunk of Section Space, longer flat tube inserting paragraph will lead to the reduction of header hydraulic diameter, thereby increase refrigeration
Agent is in the circulating resistance in header, and thus the larger pressure drop of caused refrigerant then can generate negative shadow to system performance
It rings.
Therefore it is simple to be badly in need of a kind of structure, it is possible to reduce the pressure loss of working medium, and then improve changing for micro-channel heat exchanger
The microchannel heat sink of the thermal efficiency.

Be additionally provided in flow tube it is several for plugging the jacks of the micro-channel flat, the periphery of the jack be fixed be enclosed in it is described micro-
Inclusion plate outside the flat tube of channel, the end that the inclusion plate is extend into the first passage is connected with the liquid separatnig plate, and institute
It states inclusion plate and stretches out one end of the header and be fixed with around being enclosed in the first lapping plate on the outside of the micro-channel flat, it is described
The second lapping plate with first lapping plate overlap joint setting, first lapping plate and institute are equipped on the outside of micro-channel flat
It states the second lapping plate to be fixedly connected, forms spatia, the micro-channel flat between the inclusion plate and the micro-channel flat
End sidewalls be equipped with several apertures, the spatia by the aperture and the micro-channel flat fluid communication, it is described
Liquid separatnig plate is equipped with the intercommunicating pore for being connected to first passage, second channel and spatia with the inclusion plate.
Preferably, be connected with inlet tube and outlet tube on one of them described header, and be equipped in the header one every
Plate, the partition is between the inlet tube and the outlet tube.
Preferably, first lapping plate is equipped with towards the first annular vertical plate on the outside of the header, and described second
Lapping plate is equipped with the second annular vertical plate that button is overlapped on the outside of the annular vertical plate, and first lapping plate and described second
Lapping plate is by being welded and fixed.
Preferably, by being welded and fixed between the inclusion plate and the jack.
Preferably, by being welded and fixed between the inclusion plate and the liquid separatnig plate.
The beneficial effects of the utility model are: allowing the liquid flowed into from feed liquor second by setting liquid separatnig plate
Without hindrance flowing in channel, due between micro-channel flat and second channel for be in fluid communication, liquid can directly into
Enter into micro-channel flat, therefore not only water flow not will cause the impact for micro-channel flat not only, but also due to first logical
It is to be connected to by intercommunicating pore, therefore the liquid in spatia is flowed into from second channel between road and second channel and spatia
Body can be entered in micro-channel flat by aperture, therefore can also improve the heat exchange efficiency of micro-channel heat exchanger, when micro- logical
When road flat tube and header are attached, it is only necessary to by being welded and fixed between the first lapping plate and the second lapping plate, and
Since the first lapping plate and the second lapping plate are outside header, header can also be protruded into avoid micro-channel flat
It is internal excessive, occupy excessive header inner space.
