Abstract
The utility model relates to a small-diameter copper tube heat exchanger for separation air conditioner outdoor units, which is composed of a copper tube 1 and an additional fin 2. The copper tube 1 is a high efficient heat exchanging tube whose outer diameter is between 6.5 mm to 7.5 mm. The inner wall of the high efficient heat exchanging tube is screw shaped. Under the condition that the size of the diameter of an ordinary tube is equal to the size of the diameter of the high efficient heat exchanging tube, the inner surface area of the high efficient heat exchanging tube is bigger than the inner surface area of the ordinary tube, so the heat conducting property is improved. Although the outer diameter of the copper tube 1 is diminished and is between 6.5 mm and 7.5 mm, the copper tube 1 can meet the need of heat exchange for air conditioners. As the diameter of the copper tube 1 is diminished, the additional fin 2 which is matched with the copper tube 2 is diminished. Accordingly, the size and weight of a heat exchanger are decreased. Therefore, the cost is reduced, and an air conditioner outdoor unit can be more easily installed.
Description
The utility model is the air-conditioner parts, particularly the heat exchanger of outdoor machine of body-separated air-conditioner group.
Copper pipe on the existing outdoor machine of body-separated air-conditioner group heat exchanger all is that employing copper pipe inwall is the common tube of light face, and medium flowing in common tube is laminar flow, and laminar flow is unfavorable for heat exchange, and heat conductivility is poor.Because the heat conductivility of common tube is poor, must increase copper pipe internal surface area (promptly increase caliber or increase pipeline), could satisfy the needs of air-conditioner heat exchange.All adopt the big caliber copper pipe of external diameter on the outdoor machine of body-separated air-conditioner group heat exchanger now greater than 9mm.Because heat exchanger adopts big caliber copper pipe, with supporting the adding fin and also will increase of copper pipe, the volume and weight of heat exchanger is increased on the copper pipe, like this, not only cost improves, and makes troubles to the installation of outdoor machine of body-separated air-conditioner group.
The purpose of this utility model is: provide a kind of and can make the tubule footpath copper pipe heat exchanger that outdoor machine of body-separated air-conditioner group volume and weight reduces, cost reduces.
For achieving the above object, solution of the present utility model is: it by copper pipe, add fin and form, copper pipe is that external diameter is 6.5 to 7.5mm efficient heat-exchange tube.
Owing to adopted the efficient heat-exchange tube of good heat conductivity, and the inwall of efficient heat-exchange tube is a screw-like, under equal caliber condition, the internal surface area of efficient heat-exchange tube is greatly greater than the internal surface area of common tube, and heat conductivility improves greatly.When the copper pipe caliber is reduced into 7mm, also can satisfy the needs of air-conditioner heat exchange.Because the copper pipe caliber dwindles, the volume that add fin supporting with copper pipe also and then dwindles, and heat exchanger volume and weight are reduced, and like this, both reduced cost, can make the installation of air-conditioner outdoor unit group more convenient again.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is the utility model structural representation.
Fig. 2 is the cutaway view of high-efficiency heat conduction copper pipe.
High-efficiency heat conduction copper pipe as shown in Figure 2, the inwall of copper pipe 1 are screw-like, and it not only makes the internal surface area of copper pipe 1 increase, and also can make the medium that flows in the copper pipe 1 produce turbulent flow, more help heat exchange.
Heat exchanger as shown in Figure 1, it is the high-efficiency heat conduction copper pipe 1 of 7mm by external diameter and adds fin 2 and form, because the caliber of copper pipe 1 narrows down to 7mm, the volume that add fin 2 supporting with copper pipe 1 also can reduce greatly, and equal conditions can make the volume of outdoor machine of body-separated air-conditioner group have only about 60% of original volume down.
In addition, because caliber dwindles, the flow velocity of medium can increase in the pipe, and the heat transfer efficiency of heat exchanger is improved, and at this moment, can consider to increase the rotating speed of outdoor unit exhaust fan, strengthens the ability of the outside exhaust of outdoor unit.
