Abstract
The invention discloses a refrigerant shunt head for a heat pump. The heat pump comprises a compressor, an outdoor air-cooled heat exchanger, a throttle valve, an indoor water-cooled heat exchanger, a vapor-liquid separator and a four-way reversing valve. The outdoor air-cooled heat exchanger comprises a refrigerant shunt head having an inlet portion and an outlet portion, the inlet portion comprising a cylinder cavity, a separating baffle being provided between the inlet portion and the outlet portion, the inlet portion comprising six inlets for the refrigerant to flow in, and the outlet portion comprising seven outlets including a main outlet in the centre and six subordinate outlets around the main outlet. All of the inlets are uniformly arranged on the circumferential edges of the separating baffle. The main outlet has a diameter greater than that of the subordinate outlets. The outlet portion protrudes out of the separating baffle by a preset height. The refrigerant shunt head provided by the invention can be molded in one time, is simple in the structure and low in the cost, and can automatically adjust the optimal shunting proportion through an internally-arranged shunting cavity.

Chinese invention patent application 201010186761.2 discloses a kind of coolant flow divider, and it suppresses rocking of orifice plate, will shunt ratio and stably remain necessarily, and realize low noise.Be provided with the shunting member of cone shape at the cold-producing medium distributary division with cold-producing medium shunting, and be provided with the orifice plate of the axle that is positioned at cone, suppress orifice plate by locating snap ring, locating snap ring along the flow direction of cold-producing medium to orifice plate (34) application of force.This shunt head is too complicated, need to the inhibition orifice plate be set in inside, and manufacturing process is very complicated.
Chinese invention patent application 200910161077.6 discloses a kind of adjustable refrigeration agent distributor for refrigeration system.Refrigerant distributor according to the present invention comprises: inlet pipe, bridging tube body and multiple branch circuit pipe, cold-producing medium enters described inlet pipe, after described bridging tube body shunting, enter into described multiple branch circuit pipe, described bridging tube body comprises the cylindrical shell of a hollow, and this cylindrical shell comprises the control device that an adjusting device and that is used for regulating the circulation of described cold-producing medium is used for controlling described adjusting device.Equally, this structure is also very complicated, need to regulate optimum flow according to operating mode.
Summary of the invention
The present invention mainly is the technical problem that solves the existing deficiency of prior art, thereby a kind of simple in structure, cheap for manufacturing cost and cold-producing medium shunt head that shunting effect is good is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: the shunt head of the cold-producing medium that a kind of heat pump is used, described heat pump comprises compressor, outdoor air cooling heat exchanger, choke valve, indoor water cooling heat exchanger, vapour liquid separator and four-way change-over valve, described outdoor air cooling heat exchanger comprises the shunt head of a cold-producing medium, described shunt head is incorporated into oral area and export department, described inlet portion comprises a cylinder cavity, be provided with one between described inlet portion and the export department and separate dividing plate, described inlet portion comprises 6 and is used for the entrance that cold-producing medium flows into, described export department comprises 7 outlets, and described 7 outlets comprise one and are positioned at the primary outlet at center and around 6 sub-outlets of described primary outlet.
As preferably, described entrance evenly is arranged on the circumferential edges of described separation dividing plate.
As preferably, the diameter of described primary outlet is greater than the diameter of described sub-outlet.
As preferably, described separation dividing plate one preset height is given prominence to by described export department.
Therefore, by technique scheme, cold-producing medium shunt head energy time processing of the present invention moulding, simple in structure, with low cost, can automatically regulate best shunt ratio by built-in shunting chamber.
