A kind of current equalizer that is used for the evaporimeter separatory by this purpose design comprises feed liquor house steward and separatory arm, and its architectural feature is also to comprise feed liquor flange and uniform flow orifice, and feed liquor flange and uniform flow orifice surround the static pressure chamber jointly; After feed liquor house steward's a end passes the feed liquor flange, stretch in the static pressure chamber; Uniform flow orifice is provided with the installing hole that is used to install the separatory arm more than two, after an end of separatory arm passes installing hole, stretches in the static pressure chamber.
Described uniform flow orifice is provided with the water conservancy diversion projection towards feed liquor house steward central authorities.
Described water conservancy diversion projection is coniform.
The angle in the cross section of described water conservancy diversion projection is 120 °.
The center line of described water conservancy diversion projection and the coaxial setting of feed liquor house steward's center line.
Described feed liquor house steward's a end stretches into 0.7 times of diameter that distance in the static pressure chamber is the separatory arm.
It is 0.5 times of feed liquor house steward diameter that one end of described separatory arm stretches into distance in the static pressure chamber.
Current equalizer in the utility model is made up of feed liquor flange and uniform flow orifice two parts, feed liquor flange and uniform flow orifice welding fabrication.Be used for the feed liquor house steward and the welding of feed liquor flange of refrigerant feed liquor, introduce refrigerant, through the current equalizer separatory, discharge, because the current-sharing effect of current equalizer can guarantee the cold medium flux equalization of discharging in each separatory arm from each the separatory arm that is welded on the uniform flow orifice.
Compare with traditional shunting mode, the current equalizer that the utility model adopts is through the static pressure shunting in water conservancy diversion projection water conservancy diversion and the static pressure chamber, can guarantee that the flow in each separatory arm equates, the evaporation capacity of each heat exchanger is suitable, prevent the surperficial frosting of heat exchanger, effectively improved net for air-source heat pump units efficiency and heating capacity.
The utility model can be applied in the net for air-source heat pump units, particularly works as air-side heat exchanger, is evaporimeter when heating, when forming by many; The cold medium flux that it has simple and reasonable, flexible operation, flow out from each separatory arm equates, effectively prevents the surperficial frosting of heat exchanger, has improved net for air-source heat pump units efficiency and heating capacity, advantage of wide range of application.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of the utility model one embodiment.
Fig. 2 is that A-A among Fig. 1 is to the sectional structure schematic diagram.
Among the figure: 1 is the feed liquor house steward, and 2 is the feed liquor flange, and 3 is uniform flow orifice, and 3.1 is projection, and 4 is the separatory arm, and 5 is the static pressure chamber.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1-Fig. 2, a kind of current equalizer that is used for the evaporimeter separatory comprises feed liquor house steward 1 and separatory arm 4 and feed liquor flange 2 and uniform flow orifice 3, and feed liquor flange 2 and uniform flow orifice 3 surround static pressure chamber 5 jointly; After an end of feed liquor house steward 1 passes feed liquor flange 2, stretch in the static pressure chamber 5; Uniform flow orifice 3 is provided with the installing hole that is used to install separatory arm 4 more than two, after an end of separatory arm 4 passes installing hole, stretches in the static pressure chamber 5.Separatory arm 4 is arranged on uniform flow orifice 3 in the form of a ring.
Uniform flow orifice 3 is provided with the water conservancy diversion projection 3.1 towards feed liquor house steward 1 central authorities.Water conservancy diversion projection 3.1 is coniform.The angle in the cross section of water conservancy diversion projection 3.1 is 120 °.The center line of water conservancy diversion projection 3.1 and the coaxial setting of feed liquor house steward 1 center line.The distance h 1 that one end of separatory arm 4 stretches in the static pressure chamber 5 are 0.5 times of feed liquor house steward 1 diameter d 1.
