Abstract
The invention discloses a refrigerant distribution device which comprises a first chamber, a second chamber and a third chamber, wherein the first chamber comprises an inlet for the inflow of liquid refrigerant; the second chamber comprises a distribution and guide device; the third chamber comprises a plurality of refrigerant outlet pipes; the distribution and guide device comprises a first guide plate and a second guide plate; the center of the first guide plate is provided with a guide hole; the center of the second guide plate is provided with a guide cone; and the size of the guide hole is matched with the size of the guide cone. According to the refrigerant distribution device, the refrigerant can be quickly distributed with an extremely low pressure drop through the conical distribution and guide device in the refrigerant distribution cavity.
Description
Technical field
The present invention relates to a kind of refrigeration plant, or rather, is a kind of distributor of the cold-producing medium for evaporimeter.
Background technology
In general refrigeration system, comprise compressor, condenser, throttling arrangement and evaporimeter.Cold-producing medium needs to distribute each the road coil pipe that enters into evaporimeter to carry out evaporation and heat-exchange through after the throttling.Therefore, the part flow arrangement of cold-producing medium just seems particularly important.
Chinese invention patent application discloses 200910212143.8 and discloses a kind of distributor and the refrigerant-cycle systems that comprises this distributor.To be assigned to via the cold-producing medium that inlet tube flows into a plurality of outlets by distributor, described distributor comprises: entrance channel, and the liquid phase refrigerant and the vapor phase refrigerant that flow into from inlet tube flow this entrance channel; Distribute runner, its reception flow into liquid phase refrigerant and the vapor phase refrigerant of entrance channel, and liquid phase refrigerant and the vapor phase refrigerant that receives is assigned to a plurality of outlets; And distribution projection, it makes cold-producing medium be assigned to equably outlet via allocation units.The structure of this distributor is too complicated, and manufacture difficulty is large.
Chinese invention patent application discloses 200910132009.7 and discloses a kind of refrigerant distributor for heat exchanger, this refrigerant distributor comprises: the pipe that is used for the assignment system cryogen, described pipe has the passage that is used for flow of refrigerant in described pipe, and wherein said passage has the part that at least one cross-sectional area dwindles.The volume of this distributor is larger, and the pressure drop that cold-producing medium causes in assigning process is excessive.
Summary of the invention
The present invention mainly is the technical problem that solves the existing insufficiency of function of prior art, thereby a kind of simple in structure, distributed uniform and the little refrigerant distributing device of pressure drop are provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of refrigerant distributing device, comprise the first chamber, the second chamber and the 3rd chamber, described the first chamber comprises one and is used for the entrance that liquid refrigerant flows into, the second described chamber comprises one and distributes guiding device, and described the 3rd chamber comprises the outlet of some refrigeration.
As preferably, described distribution guiding device comprises one first deflector and one second deflector, the central authorities of described the first deflector are provided with a pod apertures, and described the second deflector central authorities are provided with a deflection cone, and the size of described pod apertures and the size of described deflection cone adapt.
As preferably, described outlet is arranged on described the second deflector.
As preferably, the diameter of described the first chamber is less than the second chamber, and the diameter of described the second chamber is less than the 3rd chamber.
Therefore, by technique scheme, refrigerant distributing device of the present invention utilizes the distribution guiding device of the taper in the cold-producing medium distribution cavity, so that cold-producing medium obtains distributing fast and pressure drop is minimum, structure is small and exquisite simple.
