The heat exchange for water heater 100 of embodiment according to a first aspect of the present invention is described with reference to figure 1- Fig. 3 first below
Device.Firstly the need of explanation, the water heater 100 according to the present invention can be heat pump water heater 100, and heat exchanger is used as this
The condenser of water heater 100.
As shown in Figure 1-Figure 3, the heat exchanger for water heater 100 according to embodiments of the present invention includes flat pipe heat exchanger
10, wherein water heater 100 includes the water tank 20 of tubular, the accommodating chamber for holding water is limited in water tank 20, heat exchanger is wrapped in
The outside of water tank 20 to the water in water tank 20 to play a part of heating, so as to which water tank 20 can be as the water container of hot water.
Alternatively, the shape of water tank 20 can be various, such as can be square tube, circular cylinder, oval cylinder etc., specifically, water
The length dimension of case 20 is more than the size of its width or radial direction, it is possible thereby to make the structure of water tank 20 simply easily realize.
The length direction of wherein water tank 20 is properly termed as the axial direction of water tank 20.
In an embodiment of the present invention, flat pipe heat exchanger 10 is twist wrapped in the outside of water tank 20, flat pipe heat exchanger
10 include multiple flat segments 1, and axial direction of multiple flat segments 1 along water tank 20 is arranged at intervals, led between two neighboring flat segments 1
Tilting section 2 is crossed to be connected.
Wherein the bearing of trend of flat segments 1 is vertical with the axial direction of water tank 20, that is to say, that parallel to water tank 20
In the plane of axial direction, the orthographic projection of flat segments 1 is horizontal；Because water tank 20 is cylindrical in shape, therefore the outer wall of water tank 20 is arc
Face, arcwall face when flat segments 1 are wrapped in the outside of water tank 20 also with the outer wall of water tank 20 are bent, that is to say, that perpendicular to water
In the axial plane of case 20, the projection of flat segments 1 is curved.
The axial direction of the bearing of trend of tilting section 2 and water tank 20 is at an acute angle, that is to say, that in the axle parallel to water tank 20
To plane on, the orthographic projection of tilting section 2 is oblique；Because water tank 20 is cylindrical in shape, therefore the outer wall of water tank 20 is arcwall face,
Arcwall face when tilting section 2 is wrapped in the outside of water tank 20 also with the outer wall of water tank 20 is bent, that is to say, that perpendicular to water tank
In 20 axial plane, the projection of tilting section 2 is curved.
Heat exchanger for water heater 100 according to embodiments of the present invention, it is straight by the way that flat pipe heat exchanger 10 is separated into
The multi-segment structure of section 1 and tilting section 2, from regardless of whether the flat pipe heat exchanger 10 of flat segments 1 or tilting section 2 can be with water tank 20
Outside wall surface fully contact, the outside wall surface for reducing flat pipe heat exchanger 10 and water tank 20 produces contact gap, so as to influence heat exchange effect
Fruit.By making flat segments 1 and tilting section 2 are straggly to be each other connected, so as to easily and efficiently realize that flat pipe heat exchanger 10 exists
Spiral winding arrangement outside water tank 20, the space shared by flat pipe heat exchanger 10 thus can be not only greatly reduced,
And arrangement of the flat pipe heat exchanger 10 on water tank 20 is more flexible, pacify when the outside of water tank 20 is provided with interference flat pipe heat exchanger 10
, can be neatly due to this arrangement of water tank 20 during the part of dress, such as during the structure such as connecting bolt, rivet, support
Avoid above-mentioned part.
The heat exchanger for water heater 100 according to embodiments of the present invention is described in detail below with reference to Fig. 1-Fig. 3.
As shown in Figure 1-Figure 3, the heat exchanger for water heater 100 according to embodiments of the present invention, including flat pipe heat exchanger
10.Flat pipe heat exchanger 10 is twist wrapped in the outside of water tank 20.
In an embodiment of the present invention, water tank 20 is formed as cylindrical shape, it is possible thereby to be more prone to the shaping of water tank 20.
Alternatively, multiple flat segments 1 are divided into multigroup, alternatively, a flat segments 1 can be included in every group, can also
Including multiple flat segments 1.Flat segments 1 in every group are relative on the axial direction of water tank 20, that is to say, that in the axle of water tank 20
Corresponding one or more flat segments 1 are divided into one group on to direction, i.e. every group of one or more flat segments 1 are located at same circle
On element cylinder.Flat segments 1 in different groups are staggered on the axial direction of water tank 20 and are staggered in radial directions, that is,
Say, the flat segments 1 in different groups are located on different cylinder buses in the axial direction of water tank 20, each straight in different groups
Section 1 is not relative each other in the radial direction of water tank 20.In other words, flat pipe heat exchanger 10 is wrapped in a circumference side on water tank 20
To multiple flat segments 1 can be included, such as can be two flat segments, 1, three 1 even more flat segments of flat segments.By
This, makes multiple flat segments 1 in the outer scattered of water tank 20 and is uniformly distributed, and is advantageous to improve heat exchange uniformity, and then improve
Heat transfer effect.
Certainly the present invention is not limited thereto, and multiple flat segments 1 can also be formed as one group, and this group of flat segments 1 are in water tank
Relative on 20 axial direction, in other words, flat pipe heat exchanger 10 is wrapped in a circumferencial direction on water tank 20, can include one
Individual flat segments 1, the both ends of the flat segments 1 are connected by tilting section 2.
Wherein, the example as described in Fig. 1-Fig. 3, arc transition between tilting section 2 and flat segments 1, it is possible thereby to ensure flat
The more smooth-going of the arrangement of heat exchange of heat pipe 10, it can flow the refrigerant in flat pipe heat exchanger 10 and more smooth out, reduce refrigerant stream
Dynamic resistance.
As shown in Figure 1-Figure 3, the both ends open of flat pipe heat exchanger 10 is respectively adjacent to the axial both ends of water tank 20, in the present invention
Also include header 30 in the water heater 100 of embodiment, header 30 is connected with the end of flat pipe heat exchanger 10, so as to right
Refrigerant plays afflux effect, facilitates the connection of flat pipe heat exchanger 10 in refrigeration systems.In an embodiment of the present invention, neighbouring water
The flat pipe heat exchanger 10 at the axial both ends of case 20 is flat segments 1, and thus, the both ends of flat pipe heat exchanger 10 can be extend horizontally away
It is connected after going with header 30, attachment structure is simple.
As shown in Figure 3, it is preferable that header 30 can be with water tank 20 in being arranged side by side, i.e. the axis extension of header 30
Direction can be with parallel with the axis bearing of trend of water tank 20, and thus the both ends of flat pipe heat exchanger 10 can be with horizontally extending
Afterwards, it is directly inserted into the tube wall of header 30, space arrangement is more flexible, and the flowing smooth-going and distribution of refrigerant are more uniform,
Good effect of heat exchange.
As shown in Figures 2 and 3, the opening direction of two flat segments 1 at the axial both ends of neighbouring water tank 20 is on the contrary, i.e. flat tube
The direction of two ports of heat exchanger 10 away from one another, it is possible thereby to which two headers 30 are arranged in into water tank 20
The left and right sides, it can further improve the convenience that flat pipe heat exchanger 10 is connected with header 30.
Below with reference to Fig. 1-Fig. 3, a specific example according to the present invention is described.As illustrated, in the reality of the present invention
