Abstract

The utility model discloses a novel coolant split-flow tee joint, which comprises a liquid inlet pipe and two liquid outlet pipes. A turbulent flow generator is arranged at the position of an inlet of the liquid inlet pipe; the turbulent flow generator is a cylinder; a spiral groove is arranged on the outer circumferential surface of the cylinder; an inlet of the spiral groove is communicated with the inlet of the liquid inlet pipe; an outlet of the spiral groove is respectively communicated with the liquid outlet pipes. When coolants flowing into the tee joint from the liquid inlet pipe flow through the turbulent flow generator, turbulent flow is generated as the coolants need to spirally enter the tee joint, and liquid-state and steam-state coolants are sufficiently mixed, thereby avoiding uneven split flow that the liquid content of downflow outlet branching coolants is comparatively large while the gas content of upflow outlet branching coolants is comparatively large because of gravity. Moreover, the novel coolant split-flow tee joint improves heat exchange efficiency, decreases material consumption, has simple structure and reduces manufacturing cost.

Description

Novel coolant distribution threeway

Technical field

The utility model relates to a kind of threeway, particularly relates to a kind of novel coolant distribution threeway.

Background technology

At present, air-conditioner more and more is applied in family life and the routine office work.Raising along with the efficiency standard, the area of heat exchanger is also increasing, and heat exchange area has produced the uneven along separate routes problem that causes the heat exchange efficiency variation on the contrary thereupon after increasing, though promptly increased heat exchange area, but unreasonable owing to designing along separate routes, cause heat exchange property not obtain due raising.Traditional three-port structure as shown in Figure 1, the flow schematic diagram of refrigerant as shown in Figure 2 during use, the laminar flow phenomenon has appearred in the refrigerant that flows into threeway, be that steam state refrigerant 11 has occurred separating with liquid refrigerants 12, and owing to the gravity reason, make bigger liquid refrigerants 12 major parts of density flow to time outlet along separate routes, and less steam state refrigerant 11 major parts of density have flowed to upper outlet along separate routes, like this then cause the shunting inequality of refrigerant.

As seen, at large tracts of land, many heat exchangers along separate routes, refrigerant uniformity has along separate routes become a technical barrier on the Air-conditioner design.

The utility model content

Technical problem to be solved in the utility model is to solve the uneven along separate routes problem of heat exchanger refrigerant.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of novel coolant distribution threeway, comprises a feed tube and two drain pipes, and the import department of described feed tube is provided with turbulator.

In the such scheme, described turbulator is that a cylinder and this cylindrical external peripheral surface are provided with spiral groove, and the inlet of this spiral groove communicates with the import of feed tube, and the outlet of spiral groove communicates with drain pipe respectively.

The utility model, flow into the refrigerant of threeway from feed tube, when flowing through turbulator,, therefore produced turbulent flow owing to enter with needing spirality, liquid and steam state refrigerant fully mixes, thereby avoided flowing out the bigger shunting uneven phenomenon of cold media gas content along separate routes and go up, improved heat exchange efficiency, reduced consumptive material because the following outflow shunt cooling medium liquid body burden that gravity causes is bigger, simple in structure, reduced manufacturing cost.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is made detailed explanation.

As shown in Figure 3, the utility model comprises a feed tube 1 and two drain pipes 2, the import department of feed tube 1 is provided with turbulator 3, turbulator 3 is that a cylinder and this cylindrical external peripheral surface are provided with spiral groove 4 (referring to Fig. 5), the inlet of this spiral groove 4 communicates with the import of feed tube, and the outlet of spiral groove communicates with drain pipe respectively.

The utility model in use, flow into the refrigerant of threeway from feed tube 1, when flowing through turbulator 3, owing to enter with needing spirality, therefore produced turbulent flow, liquid refrigerants 22 and steam state refrigerant 21 fully mix, thereby have avoided because the following outflow shunt cooling medium liquid body burden that gravity causes is bigger, flow out the bigger shunting uneven phenomenon of cold media gas content along separate routes and go up, the flow schematic diagram of its refrigerant as shown in Figure 4.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
