Detailed Description
The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
Referring to fig. 1, the heat exchange aluminum pipe comprises an aluminum pipe body 1 and a heating cavity 2 fixed in the aluminum pipe body 1 and arranged coaxially with the aluminum pipe body 1, wherein the heating cavity 2 is positioned at one end of the aluminum pipe body 1, and the length of the heating cavity 2 is smaller than that of the aluminum pipe body 1.
As shown in fig. 1, a water inlet 22 is formed at an end of the heating chamber 2, a supporting circular plate 3 is fixedly connected to the end of the heating chamber 2, which is far away from the water inlet 22, coaxially, and the outer circumference of the supporting circular plate 3 is fixed to the inner side wall of the aluminum pipe body 1, water discharge holes 31 (see fig. 2) are arranged in the circumferential direction of the supporting circular plate 3, and a plurality of water discharge holes 21 are formed in the outer side wall of the heating chamber 2. The heating chamber 2 is internally welded with a support plate 9, one end of the support plate 9 is welded with an electric heating element 4, the electric heating element 4 is close to the water inlet hole 22, and the electric heating element 4 can be a heating wire or an electric heating rod. When the heating cavity 2 works, water enters the heating cavity 2 from the water inlet hole 22, the water in the heating cavity 2 is heated by the electric heating element 4, and the heated water is firstly discharged into a cavity formed by the supporting circular plate 3 and the outer side wall of the heating cavity 2 from the water outlet hole 21 and then uniformly discharged into the aluminum pipe body 1 from each water discharge hole 31. The heating cavity 2 is provided, so that part of water can be preheated, and the heating speed of the water can be increased. The drain holes 31 equalize the amount of hot water entering the aluminum pipe body 1, so that the heated water is conveniently filled in the entire passage, thereby improving heat exchange performance and improving the efficiency of the entire aluminum heating pipe.
As shown in fig. 1, the supporting circular plate 3 is coated with the heat conducting layer 6, and during the process of discharging the heated water from the water discharging hole 31, the heat of the water is transferred to the aluminum pipe body 1 through the heat conducting layer 6, thereby further improving the heat exchange performance.
As shown in fig. 1, the wave groove 5 is formed in the inner side wall of the aluminum pipe body 1 along the length direction, and the wave groove 5 not only increases the contact area between water flow and the aluminum pipe body 1, but also reduces the wall thickness of the aluminum pipe body 1, facilitates heat transfer of the aluminum pipe body 1, and improves heat exchange performance.
As shown in fig. 1, a first thermal insulation layer 7 is disposed on the outer side wall of the heating chamber 2, and the first thermal insulation layer 7 is made of polystyrene foam. When the electric heating element 4 stops working, the first heat preservation layer 7 makes the heat energy not easy to radiate to the outside, and has the advantage of low consumption of the external heat energy.
