According to the condenser of the embodiment of the first aspect of the present invention, the heat exchange is performed by using the refrigerant, which includes the inlet header 100, one end of which is provided with the inlet 101, and the area of the cross section of the inlet header 100 is gradually reduced along the first direction of the refrigerant flowing in the inlet header 100; a plurality of flat pipes 200, a plurality of flat pipes 200 follow the first direction and communicate with entry pressure manifold 100 in proper order, are equipped with microchannel 203 in the flat pipe 200, along the second direction that the refrigerant flowed in microchannel 203, are equipped with the protruding 202 of multiunit on microchannel 203's the inside wall 201, and the interval of adjacent protruding 202 of group reduces gradually.
For example, as shown in fig. 1, the condenser in the present embodiment includes an inlet header 100, a flat tube 200, fins 300, an outlet header 400, and a mounting plate 500. An inlet 101 is disposed at one end (e.g., the top end in fig. 1) of the inlet header 100, the inlet 101 is used for allowing external refrigerant to enter the inlet header 100, the inlet 101 may be a hole directly formed on the sidewall of the top end of the inlet header 1, or as shown in fig. 1, a connecting pipe extends from the sidewall of the top end of the inlet header 1, and a pipe orifice of the connecting pipe is used as the inlet 101. Locating the inlet 101 at the top of the inlet manifold 100 facilitates automatic flow of refrigerant under the influence of gravity.
One end (e.g., the bottom end in fig. 1) of the outlet header 400 is provided with an outlet 401, the outlet 401 is used for allowing the refrigerant to flow out of the outlet header 400, the outlet 401 may also be a hole formed on the sidewall of the bottom end of the outlet header 400, or as shown in fig. 1, a connecting pipe extends from the sidewall of the bottom end of the outlet header 400, and a pipe orifice of the connecting pipe serves as the outlet 401. Providing the outlet 401 at the bottom end of the outlet header 400 may facilitate gravity settled refrigerant to flow out of the outlet header 400.
The inlet header 100 and the outlet header 400 are connected with two mounting plates 500, and the two mounting plates 500 are respectively located at the top end and the bottom end of the inlet header 100 (or the outlet header 400). Be connected with flat pipe 200 and fin 300 between entry pressure manifold 100, export pressure manifold 400 and the mounting panel 500, it is concrete, the condenser of this embodiment includes a plurality of flat pipes 200, a plurality of flat pipes 200 along the first direction (for example the vertical direction in fig. 1) that the refrigerant flows in entry pressure manifold 100 communicate with entry pressure manifold 100 in proper order, that is, single flat pipe 200 extends along the horizontal direction in fig. 1, many flat pipes 200 stack along the vertical direction in fig. 1. Fins are arranged between adjacent flat tubes 200, and when the refrigerant flows in the flat tubes 200, heat exchange with the outside can be performed through the fins.
The area of the cross section of inlet header 100 (taking fig. 1 as an example, the cross section referred to herein is a cross section of inlet header 100 taken by a horizontal plane) is gradually reduced along a first direction, and since the flow rate of the fluid is inversely proportional to the cross section of the flow channel, the fluid flow rate farther from inlet 101 is larger, flat tube 200 farther from inlet 101 can obtain more refrigerant, and the problem of uneven heat exchange performance caused by uneven refrigerant supply is solved.
Referring to fig. 2, a protrusion 202 is arranged on an inner side wall 201 of the flat pipe 200, and the protrusion 202 occupies a part of an inner cavity of the flat pipe 200, so that a sectional area of the inner cavity at the protrusion 202 is reduced, thereby increasing a flow rate of a fluid flowing through the protrusion 202, and when the fluid is a refrigerant, increasing the flow rate can increase the heat exchange efficiency of the refrigerant. On the other hand, both sides of the protrusion 202 may be swirled to further enhance the heat exchange efficiency.
Referring to fig. 3, a plurality of sets of protrusions 202 are disposed on an inner sidewall 201 of the flat tube 200 along a second direction (e.g., a horizontal direction in fig. 1 and 3) in which the refrigerant flows in the micro channel 203, and a distance between adjacent sets of protrusions 202 is gradually reduced along the second direction. Wherein each set of protrusions 202 may comprise only one protrusion 202 (e.g., fig. 3), i.e., the distance between adjacent protrusions 202 decreases along the second direction. Each set of protrusions 202 may also include more than two protrusions 202, and the spacing between adjacent protrusions 202 within the same set may be equal. Each set of protrusions 202 may or may not include an equal number of protrusions 202, i.e., the protrusions 202 may have a tendency to gradually encrypt in the second direction. On the whole, being closer to outlet header 400, the region that can accelerate the fluid velocity on flat pipe 200 is denser, and the heat exchange efficiency of flat pipe 200 rear end can be promoted to this embodiment promptly. The number of protrusions 202 is not limited, and for example, as shown in fig. 3, protrusions 202 may be distributed substantially from the front end of flat tube 200 to the rear end of flat tube 200, or protrusions 202 may be provided only at the rear end of flat tube 200 or at the middle section and the rear end of flat tube 200.
In this embodiment, the area of the cross section of the inlet header 100 is gradually reduced along the first direction, so that the flow velocity of the refrigerant in the inlet header 100, which is farther from the inlet 101, is higher, and the flow rate of each flat tube 200 is relatively uniform. Meanwhile, the inner side wall 201 of the flat pipe 200 is provided with the plurality of groups of protrusions 201, and the distance between the adjacent groups of protrusions 202 is gradually reduced along the second direction, so that the flow speed of the rear end of the refrigerant in the single flat pipe 200 can be improved, and the heat exchange capacity of the rear end of the flat pipe is improved. Reflect the wholeness ability to the condenser, this embodiment can improve the inhomogeneous problem of each flat tub of 200 heat exchanges of condenser to a certain extent, can promote single flat tub of 200's heat transfer performance simultaneously to promote holistic heat transfer performance. In addition, the structure of the inlet collecting pipe can be simplified, and the production and machining difficulty of the inlet collecting pipe is reduced.

The second sidewall 103 is located on the opposite side of the first sidewall 102 and is inclined relative to the first sidewall 102 such that the distance between the second sidewall 103 and the first sidewall 102 is gradually reduced along the first direction, thereby achieving the effect that the cross-sectional area of the inlet header 100 is gradually reduced along the first direction.
In this embodiment, the sectional area of the inlet header 100 can be gradually reduced without changing the width of the first sidewall 102, and therefore, the flat pipe 200 connected to the first sidewall 102 does not need to be adjusted, so that the structure can be simplified, and the difficulty in production and processing can be reduced.

Referring to fig. 3 and 4, the width of the cross section of the inlet header 100 gradually increases along the second direction, and the arrangement is such that: in order to ensure the flow velocity of the refrigerant during injection, the area of the inlet 101 cannot be too large, so that most of the widths of the flat tubes 200 exceed the diameter of the inlet 101, so that the distances between the microchannels 203 which are distributed in parallel in the width direction and the inlet 101 are inconsistent, the microchannels 203 which are close to the inlet 101 obtain more refrigerant, the microchannels 203 which are far away from the inlet 101 obtain less refrigerant, so that the refrigerant is unevenly distributed in the microchannels 203 of a single flat tube 200, in this embodiment, the flow velocity of the refrigerant in the inlet collecting pipe 100 along the two sides in the width direction can be increased, so that the microchannels 203 which are far away from the inlet 101 can obtain more refrigerant, and the problem of uneven distribution of the refrigerant in the microchannels 203 of a single flat tube 200 is solved.
