Abstract
The utility model discloses a refrigerant flow branching member of an air conditioner and a branching member nozzle. The refrigerant flow branching member of the air conditioner includes a branching member body, a nozzle is arranged in the branching member body, and a plurality of nozzle holes are arranged in the nozzle. The refrigerant flow branching member prevents the distribution effect from being influenced by the flow instability factor caused by factors of gas and liquid phases and weight, and takes the effect of uniform and stable distribution.
Description
Technical field
The utility model belongs to air-conditioning duct parts, relates in particular to a kind of cold medium flux branching unit and branching unit nozzle of air-conditioner.
Background technology
Air-conditioner is mainly made up of indoor and outdoor heat exchanger, compressor, controller and system management, air-conditioner more than existing 2P is because the pipeline number of connection indoor and outdoor machine is more, in order to reduce flow and the pressure loss, refrigerant need to be divided into multiple branch roads, can cause like this cold medium flux difference in each branch road, the problem of distributing in order to solve cold medium flux, a branching unit assembly generally all can be installed in pipeline, make it distributed uniform by adjusting capillary pipe length or U-shaped pipe quantity again, thereby assurance system can better be moved.
Chinese patent CN201340150Y discloses a kind of liquid-dividing head, this liquid-dividing head one end is provided with refrigerant entrance, the other end is provided with multiple nozzle bores, described nozzle orifice size equates, is conical and is uniformly distributed, its root crosses, and forms cone shaped cavity, and this cone shaped cavity and refrigerant entrance joint are shrunk to neck, the outer imperial palace of refrigerant entrance is little, is bell mouth shape.But the discharge stability of this liquid-dividing head shunting still needs to improve.
Summary of the invention
The utility model is mainly to provide a kind of cold medium flux branching unit and branching unit nozzle of air-conditioner, mass flow discrepancy while having avoided coolant distribution.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the cold medium flux branching unit of a kind of air-conditioner of the present utility model, comprise branching unit body, in described branching unit body, be provided with nozzle, on described nozzle, be provided with some nozzle bores.In the time of operation of air conditioner, when refrigerant passes through nozzle, be evenly full of branching unit cavity because nozzle bore makes refrigerant, thereby avoided the instability of flow factor causing due to the factor such as liquid phase and weight to affect distribution effects, play the effect of uniform and stable distribution.
As preferably, described nozzle comprises nozzle panel, and described nozzle panel comprises convex globoidal and back of the body concave arc.
As preferably, described nozzle panel is that oval ball is crown.
As preferably, described nozzle also comprises side surrounding surface, and described side surrounding surface is arranged on the periphery of described nozzle panel, and side surrounding surface fits tightly on the inwall of described branching unit body.
As preferably, described branching unit body comprises tap hole, cushion chamber and refrigerant entrance, and described refrigerant entrance is welded with input pipe.
As preferably, described input pipe outer face and described nozzle offset.
As preferably, described convex globoidal is towards refrigerant entrance, and described back of the body concave arc is towards described cushion chamber, and described nozzle bore distributes.
As preferably, described nozzle and branching unit inner body wall are formed with stepped hole between described cushion chamber and described nozzle.
A kind of branching unit nozzle, comprises nozzle panel and side surrounding surface, on described nozzle panel, is provided with multiple nozzle bores, and described nozzle panel one side is convex globoidal, and another side is cancave cambered surface.
As preferably, described nozzle bore is evenly distributed on described nozzle panel.
The beneficial effect that the utility model brings is that the utility model has avoided the instability of flow factor causing due to the factor such as liquid phase and weight to affect distribution effects, plays the effect of uniform and stable distribution.
