Embodiment：
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or more
The presence or addition of individual other elements or its combination.
The utility model provides a kind of tube-in-tube heat exchanger as shown in figures 1 to 6, and it includes more heat exchanger tubes 1, described
Heat exchanger tube includes oval outer tube 101 and circular inner pipe 102, short axle and the circular inner pipe 102 in the oval section of outer tube 101
Diameter of section is equal, and the circular inner pipe 102 is welded in oval outer 101 pipes；Fin 2, the fin 2 are arranged on described
On the outer wall of heat exchanger tube 1；First water box 4 of heat exchanger tube one end are arranged on, first water box 4 connect with each oval outer tube 101
Logical, first water box 4 are provided with U-tube 3, and the U-tube 3 connects each circular inner pipe 102, first water box 4
It is provided with the first water inlet pipe 401 and the first outlet pipe 402 directly connected with the circular inner pipe 102；It is another to be arranged on heat exchanger tube
Second water box of one end, second water box include two disconnected first independent 51 and second independent water box 52 of water box, institute
State the first independent 51 and second independent water box of water box and be provided with U-tube 52, the first independent water box 51 and the oval outer tube
101 water inlet connection, the second independent water box 52 are connected with stating the delivery port that oval outer tube 102 connects, and described first is only
Vertical water box are provided with the second water inlet pipe 501, and the second independent water box are provided with the second outlet pipe 502.
When water heater is started working, the water inlet pipe of the first water box starts to intake, and the water inlet pipe of the first independent water box starts
Water inlet, because the first water box with the second water box connect each heat exchanger tube ellipse outer tube, therefore water can fill all water box and respectively change
Heat pipe ellipse outer tube, due to there is each circular inner pipe of series connection in U-tube, therefore water can fill circular inner pipe, and now fin will absorb
The heat transfer arrived gives heat exchange pipe outer wall, while the water in oval outer tube is heated for heating water, and hot water is again by heat transfer
To the cold water of circular inner pipe, it is heated for domestic water.By the short axle and circular inner pipe diameter of section of tube section outside ellipse
Equal, circular inner pipe is welded in oval outer tube so that can be not easy to have tied incrustation scale in a long time in heat exchanger, while this is tied
Structure can ensure that heat exchanger tube can bear 18 kilograms~22 kilograms of hydraulic pressure.

Water inlet pipe of the 11 liang of branch roads of shape pipe respectively with first water box and the circular inner pipe is connected, on the main road of Y tube 11
Provided with valve 7, when heat exchanger usage time is longer, incrustation scale can be generated in each pipe, it is one very numb such as to be cleaned
, it is necessary to take whole water heater apart cleaning, and due to this structure, it need to open valve by scale remover ascending pipe for tired thing
It is interior, washed away after it is by incrustation scale reaction dissolving, it is convenient and swift.
As in above-mentioned technical scheme, being randomly provided hemispherical projections 10 on the circular inner pipe wall, its raised hemisphere 10
Current can be become turbulent flow from laminar flow pressure, so as to increase heat exchange efficiency.
As in above-mentioned technical scheme, the fin through outer wall extend into the oval outer tube and the circular inner pipe it
Between, such a structure can increase heat exchange area, improve heat exchange efficiency.
As in above-mentioned technical scheme, the more heat exchanger tubes are arranged in parallel, and so arrangement can reduce heat exchanger volume.
As in above-mentioned technical scheme, the fin equidistant arrangement, the spacing between two fins is no more than 2 centimetres, this design
Heat exchanger can be made heated more balanced, such heat exchanger will not be deformed because long-term uneven heating weighing apparatus or leak.
As in above-mentioned technical scheme, the fin edges waviness, such a design can increase the heat suction of overall heat exchange device
Produce effects rate.
Number of devices and treatment scale described herein are for simplifying explanation of the present utility model.To the utility model
The application of tube-in-tube heat exchanger, modifications and variations will be readily apparent to persons skilled in the art.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality
