Abstract

The utility model provides a condenser of an outdoor air-conditioner, which can solve some problems existing in the prior art, such as the unequal distribution of flowing capacity of coolant, and the low condensate depression or the like. The technical proposal is that an air-inlet pipe is divided into an upper air-inlet pipe and a lower air-inlet pipe, a liquid-outlet pipe is divided into a first liquid-outlet pipe, a second liquid-outlet pipe, a third liquid-outlet pipe, and a forth liquid-outlet pipe, coolant coming from the upper air-inlet pipe flows into the first chief liquid-outlet pipe through the first liquid-outlet pipe and the second liquid-outlet pipe, coolant coming from the lower air-inlet pipe flows into the second chief liquid-outlet pipe through the third liquid-outlet pipe and the forth liquid-outlet pipe, and coolant coming from the first chief liquid-outlet pipe and the second chief liquid-outlet pipe respectively flows into a first subcooling inlet hole and a second subcooling inlet hole of the subcooling segment. The air-inlet pipe and the liquid-outlet pipe are changed into two inlets and four outlets from the original four inlets and four outlets, which greatly improve the heat exchanging ability, the condensation ability and the energy efficiency ratio of the whole air-conditioner.

Description

Condenser for outdoor unit of air conditioner

Technical field

The utility model relates to air conditioner, relates in particular to condenser for outdoor unit of air conditioner.

Background technology

Existing condenser for outdoor unit of air conditioner has adopted the R410A cold-producing medium, because R410A has high efficiencies of heat transfer, and low pressure loss, the low temperature drift, less characteristics such as charging amount, the R410A cold-producing medium is widely used in the refrigeration system.But the flow scheme design according to the R410A cold-producing medium in condenser also lacks specific aim, causes bringing into play the R410A self-characteristic fully effectively.For example cold-producing medium enters condenser and adopts four to advance four and go out, and four drain pipes are aggregated into one the tunnel and enter super cooled sect.Because along separate routes too much, it is inhomogeneous to make this flow scheme design flow into the refrigerant flow on every road, and especially nethermost one road refrigerant flow is less, and the distribution of bottom super cooled sect has only four U type pipes, degree of supercooling is little, thereby has influenced the refrigerating capacity and the Energy Efficiency Ratio of the integral body of air-conditioner.

How solving the technical problem of above-mentioned existence, then is the design problem that the utility model faced.

Summary of the invention

The utility model provides a kind of condenser for outdoor unit of air conditioner, and it can solve problems such as the flow distribution of refrigerant that prior art exists is inhomogeneous, degree of supercooling is little.

In order to reach the purpose that solves the problems of the technologies described above, the technical solution of the utility model is a kind of condenser for outdoor unit of air conditioner, it comprises condenser, comprise air inlet pipe, drain pipe in the condenser, it is characterized in that described air inlet pipe is two, last air inlet pipe and lower inlet duct; Described drain pipe is four, drain pipe one, drain pipe two, drain pipe three and drain pipe four, and the cold-producing medium that enters from last air inlet pipe flows out remittance main drain pipe one by drain pipe one, drain pipe two; The cold-producing medium that enters from lower inlet duct flows out remittance main drain pipe two by drain pipe three, drain pipe four; Flow into the cold import one of mistake, the cold import two excessively of super cooled sect respectively from the cold-producing medium of main drain pipe one and main drain pipe two outflows.

In the utility model, also have following technical characterictic: the U type pipe in the described super cooled sect is for more than at least 6.

The utility model compared with prior art has the following advantages and good effect: 1. air inlet pipe and drain pipe advance four by original four and go out, changing two into advances four and goes out, rationally change the distribution of refrigerant flow, increased exchange capability of heat greatly, improved the refrigerating capacity and the Energy Efficiency Ratio of air-conditioner integral body.2. increase degree of supercooling, the energy consumption of reduction unit heat exchange amount.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1 is the utility model condenser for outdoor unit of air conditioner structural representation.

1. condenser; 2.U type pipe; 3. capillary; 4. go up air inlet pipe; 5. lower inlet duct; 6. drain pipe one; 7. drain pipe two; 8. drain pipe three; 9. drain pipe four; 10. cross cold import one; 11. cross cold import two; 12. cross cold outlet one; 13. cross cold outlet two; 14. main drain pipe one; 15. main drain pipe two; 16. super cooled sect.

The specific embodiment

Referring to Fig. 1, in order to improve problems such as the flow distribution of refrigerant that prior art exists is inhomogeneous, degree of supercooling is little, design concept of the present utility model is that air inlet pipe is two, last air inlet pipe 4 and lower inlet duct 5; Drain pipe is four, drain pipe 1, drain pipe 27, drain pipe 38 and drain pipe 49, and the cold-producing medium that enters from last air inlet pipe 4 flows out remittance main drain pipe 1 by drain pipe 1, drain pipe 27; The cold-producing medium that enters from lower inlet duct 5 flows out remittance main drain pipe 2 15 by drain pipe 38, drain pipe 49; Flow into the cold import 1 of mistake, the cold import 2 11 excessively of super cooled sect respectively from the cold-producing medium of main drain pipe 1 and main drain pipe 2 15 outflows.

Crossing cold import 1, crossing cold import 2 11 is super cooled sect 16 with the lower part, and in the present embodiment, the U type pipe in the super cooled sect 16 is 8.

Condenser 1 adopts the perpendicular arrangement of inserting of 28 U type pipes, two rows, the temperature field inversion is arranged, to obtain maximum heat exchange driving force; Adopt two to advance four flow scheme design that go out, strengthen exchange capability of heat greatly, enter the super cooled sect of four U type pipes after every two-way converges respectively, take all factors into consideration the rerum natura of R410A, walked 8 super cooled sects altogether, increased degree of supercooling, reduce unit heat exchange energy consumption, improved the heat exchange efficiency of condenser.

The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
