Abstract
The utility model relates to a connecting tube of an air conditioner. Hole expanding structures are correspondingly designed on connecting tube holes of a copper tube and an aluminum tube, so as to ensure that the inner diameter of the connecting tube hole is not less than the inner diameter of the copper tube and the inner diameter of the aluminum tube, and thus, a cooling medium has no any hindrances when the cooling medium flows across the connecting tube hole and the energy consumption of the complete conditioner of the air conditioner can not raise. The connecting tube of the air conditioner comprises the aluminum tube which is inserted between copper tubes which are arranged on both sides, the copper tubes of both of the sides are respectively inserted into an aluminum tube section and the inserting section can be directly welded. The copper tube has a hole expanding structure and a hole necking structure which are adjacently arranged at the tube hole point which is formed by inserting the copper tubes and the aluminum tube, and correspondingly, both side ends of the aluminum tube are respectively has a hole expanding structure, the hole necking structure of the copper tube is directly inserted into the hole expanding structure of the aluminum tube and the inserting point can be directly welded in a resistance mode.
Description
Technical field
The utility model relates to the novel connecting tube that is used to transmit refrigerant between a kind of air conditioner indoor machine, the outdoor unit.
Background technique
Connecting pipeline between original indoor machine of air-conditioner, the outdoor unit adopts the copper pipe material.When connecting, the copper pipe two side ends is connected with the valve (or joint) of indoor set, outdoor unit by copper nut.Owing to select for use the cost of copper pipe higher, the existing improvement structure that connects the machine pipe is to adopt the welding connection structure of copper pipe and aluminum pipe.
As disclosed existing copper pipe of Fig. 1 and Al pipe butt welding structure, wherein dwindle, conveniently to be inserted into aluminum pipe 2 inside at the mouth of pipe place of copper pipe 1 internal diameter.Thereby flow to aluminum pipe 2 or when aluminum pipe 2 flows to copper pipe 1 from copper pipe 1 when refrigerant, in the mouth of pipe of the copper pipe 1 that contracts directly have influence on the flow velocity of refrigerant.Particularly work as air conditioner and be under the high load running state, the reduction of refrigerant flow rate has considerable influence for complete machine refrigeration or heating efficiency, and air conditioner prolongation working time, energy consumption raise.
The model utility content
Air conditioner described in the utility model connects the machine pipe, its purpose is to address the above problem with not enough and designed the enlarging structure accordingly at the mouth of pipe that is connected of copper pipe and aluminum pipe, thereby the internal diameter that guarantee to connect the mouth of pipe is not less than the internal diameter of copper pipe and aluminum pipe separately, thus refrigerant flow through can not be subjected to any obstruction when connecting the mouth of pipe, air conditioner complete machine energy consumption can not raise yet.
Described air conditioner connects the machine pipe, is included in the aluminum pipe of pegging graft between the copper pipe of both sides.The both sides copper pipe is inserted into the aluminum pipe intersegmental part respectively, and directly welds at splicing position.
Mouth of pipe place in described copper pipe and aluminum pipe grafting, copper pipe has an enlarging structure and a throat structure of adjacent setting, correspondingly the aluminum pipe two side ends has an enlarging structure respectively, and the throat structure of copper pipe directly is inserted into the enlarging inside configuration of aluminum pipe, and directly carries out resistance welding at splicing position.
The throat structure internal diameter of copper pipe and copper pipe internal diameter, aluminum pipe internal diameter are identical, thereby flow to aluminum pipe or when aluminum pipe flows to copper pipe from copper pipe when refrigerant, and refrigerant can't be hindered connecting mouth of pipe place.
For realizing the antisepsis of copper, Al pipe butt welding point, can apply one deck insulating corrosion protective layer at the surface or the connection mouth of pipe place of whole connecting tube.Or be used as anticorrosive coat connecting the sheathed heat-shrink tube in mouth of pipe place.
As above content, air conditioner described in the utility model connects the machine pipe and has the following advantages:
1, the internal diameter at connection mouth of pipe place is little unlike the internal diameter of copper pipe or aluminum pipe, and under the prerequisite that adopts the copper aluminum pipe to peg graft, refrigerant flow rate can not reduce, the air conditioner energy consumption can not raise;
2, described simple for structure, the good seal performance of machine pipe enlarging that connects also has the insulating corrosion performance simultaneously.
Description of drawings
Fig. 1 is the connection mouth of pipe place structural representation that existing air conditioner connects the machine pipe;
Fig. 2 is the connection mouth of pipe place structural representation that connects the machine pipe described in the utility model.
Wherein, as shown in Figure 1, copper pipe 1, aluminum pipe 2, copper pipe throat structure 3, copper pipe spout diameter R1 and copper pipe internal diameter R2.
As shown in Figure 2, copper pipe 4, aluminum pipe 5, copper pipe throat structure 41, enlarging structure 42, aluminum pipe enlarging structure 51, plastic-blasting protective layer 52, and copper pipe internal diameter R3, copper pipe enlarging structure internal diameter R4, copper pipe throat structure internal diameter R5 and aluminum pipe internal diameter R6.
Embodiment
As shown in Figure 1, existing air conditioner connects the machine pipe, and the copper pipe throat structure 3 of its copper pipe 1 is inserted into aluminum pipe 2 inside.
Wherein, copper pipe spout diameter R1 is less than copper pipe internal diameter R2, thereby flows to aluminum pipe 2 or when aluminum pipe 2 flowed to copper pipe 1, copper pipe throat structure 3 directly had influence on the flow velocity of refrigerant from copper pipe 1 when refrigerant.
Embodiment 1, and as shown in Figure 2, described air conditioner connects the machine pipe, the aluminum pipe 5 of pegging graft between both sides copper pipe 4.
At described copper pipe 4 and aluminum pipe 5 splicing positions, copper pipe 4 has adjacent copper pipe throat structure 41 and enlarging structure 42, and aluminum pipe 5 has aluminum pipe enlarging structure 51, and copper pipe throat structure 41 directly is inserted into the inside of aluminum pipe enlarging structure 51.
Structure as shown in Figure 2, copper pipe internal diameter R3 is all identical with copper pipe throat structure internal diameter R5, aluminum pipe internal diameter R6, and copper pipe enlarging structure internal diameter R4 is greater than copper pipe throat structure internal diameter R5.
The place also is coated with a plastic-blasting protective layer 52 at the connection mouth of pipe.
Claims (4)
