Abstract

The utility model discloses a heat exchange device of an air conditioner. By adopting the flow path design of three-path inlet and one-path outlet, the refrigerant can be reasonably shunted and the heat exchange effect and the energy consumption of the entire machine can be balanced. The heat exchange device mainly comprises a group of tube plates and two rows of heat exchange tube paths arranged among the tube plates, wherein every row of heat exchange tube path is provided with a plurality of U-shaped tubes, a plurality of radiating fins on the surfaces of the U-shaped tubes, elbows arranged at the side ends of the U-shaped tubes, an air inlet group and an air outlet group. Three parallel inlets for leading in a refrigerant are totally arranged on a plurality of U-shaped tubes; and an outlet for leading out the refrigerant is arranged on the air outlet group. By adopting the flow path design of the three-path inlet and one-path outlet, the refrigerant is respectively led to the heat exchange device from the three U-shaped tubes through the air inlet group and led out from one outlet on the air outlet group, so that the flow speed of the refrigerant is correspondingly improved; and the flow path resistance of the refrigerant shunted to three paths is effectively reduced, so that the heat exchange effect of the heat exchange device is more remarkable.

Description

The air-conditioner heat-exchanger rig

Technical field

The utility model is the architecture advances at the air-conditioner heat-exchanger rig, takes 3 the tunnel to advance 1 tunnel refrigerant flow project organization that goes out particularly, belongs to air-conditioning HVAC technical field.

Background technology

The cooling cycle system of detachable air conditioner mainly has pipeline assemblies such as indoor heat exchanger, outdoor heat exchanger, compressor assembly and choke valve.Wherein the effect outbalance of outside heat-exchanger rig (being called condenser at large) mainly is to carry out heat exchange efficiently with external environment condition, and the heat exchange efficiency of outside heat-exchanger rig will directly have influence on the complete machine efficiency.

The coolant distribution mode of existing outdoor heat exchanger takes 2 the tunnel to advance 1 the tunnel and go out or 4 the tunnel advance 2 the tunnel and go out or 4 the tunnel advance 1 tunnel flow passage structure design that goes out usually.Main problem and the defective that exists is that if take 2 tunnel shunting modes that advance, though can increase flow velocity to improve the heat exchange effect in the kind of refrigeration cycle process, the resistance that refrigerant runs in the flow process is bigger, so efficiency is lower.If get 4 tunnel shunting modes that advance, cause complete machine heat exchange effect not good enough owing to flow velocity is lower though can lower flow path resistance.

The utility model content

Air-conditioner heat-exchanger rig described in the utility model is to solve above-mentioned existing issue and takes 3 the tunnel to advance 1 tunnel flow path designs that goes out, reasonably to shunt refrigerant, balanced heat exchange effect and complete machine energy consumption.

Purpose of design of the present utility model is by improving flow passage structure with under the prerequisite that guarantees the reasonable flow velocity of refrigerant, to reduce flow path resistance, enhanced heat exchange effect effectively and improve the complete machine efficiency.

For realizing above-mentioned purpose of design, described air-conditioner heat-exchanger rig mainly includes:

One group of tube sheet,

Be arranged on the row of 2 between tube sheet heat exchanging pipe,

Every row's heat exchanging pipe has some radiating fins of several U-shaped pipes, U-shaped tube-surface, the elbow that is connected U-shaped pipe side, air inlet pipe group and escape pipe group.

The difference with the prior art part is, is provided with 3 parallel entries that import refrigerant on several U-shaped pipes altogether, is provided with 1 outlet of deriving refrigerant on the escape pipe group.

As above-mentioned essential characteristic scheme, described heat-exchanger rig adopts 3 the tunnel to advance 1 tunnel flow path designs that goes out, refrigerant is directed to heat-exchanger rig from 3 U-shaped pipes respectively by the air inlet pipe group, and final 1 outlet on the escape pipe group is derived, so refrigerant flow rate is correspondingly improved, but branch to 3 tunnel the suffered flow path resistance of refrigerant and be able to effective reduction, so the heat exchange effect of heat-exchanger rig is comparatively obvious.

For further improving the reasonability of above-mentioned design concept and the control of actual refrigerant flow rate, the corrective measure that can take is:

On same row's heat exchanging pipe, 3 parallel entries that are communicated with the air inlet pipe group and import refrigerant to the U-shaped pipe are set;

On another row's heat exchanging pipe, be provided with 3 and be communicated with collecting pipe group 5 to derive the parallel connection outlet of refrigerant;

Described collecting pipe group, the U-shaped pipe by 1 road or 2 tunnel parallel connections is communicated to the escape pipe group.

Embodiment comparatively preferred and refinement is, every row's heat exchanging pipe has 11 U-shaped pipes, and 3 parallel entries of connection air inlet pipe group are arranged at the 3rd, the 4th, the 7th U-shaped pipe of same row's heat exchanging pipe respectively;

3 outlets in parallel that are communicated with the collecting pipe group are arranged at the 3rd, the 4th, the 7th U-shaped pipe of same row's heat exchanging pipe respectively.

As mentioned above, the advantage that the utility model air-conditioner heat-exchanger rig has is, by taking 3 the tunnel to advance 1 tunnel flow path designs that goes out, can reasonably shunt refrigerant, effectively balanced refrigerant flow rate with reduce flow path resistance, be achieved the enhanced heat exchange effect and improve the complete machine efficiency.
