The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Example 1
Referring first to fig. 2A and 2B, the heat exchanger of the present invention will be described. Fig. 2A is a perspective view of a heat exchanger according to an embodiment of the present invention, in which one end of the heat exchanger is shown to be closed; fig. 2B is a top view of a heat exchanger according to an embodiment of the present invention, the heat exchanger shown having an opening at one end; fig. 2C is a schematic structural diagram of the heat exchanger in an expanded state according to an embodiment of the present invention.
As shown in fig. 2A and 2B, in order to solve the problem that the heat exchange effect of the heat exchanger of the existing cabinet air conditioner indoor unit is not ideal, the present application provides a heat exchanger, the heat exchanger 4 includes a coil 41, the coil 41 is enclosed into a cylindrical structure, and one end of the cylindrical structure is closed, and the other end has an opening. As a possible example, the heat exchanger comprises a coil 41 and a bottom plate 43, the coil 41 being of cylindrical configuration and the bottom plate being provided at one end of the coil 41 to close one end of the coil 41. Of course, in practical applications, the way of closing one end of the tubular coil 41 is not limited to the above example, and other ways are also possible, for example, the coil may be directly set to be a tubular structure with one closed end and one open end, and a person skilled in the art may set the specific structure of the coil according to practical application scenarios as long as the tubular structure is closed at one end and open at one end.
The advantage of above-mentioned setting lies in: through enclosing coil pipe 41 and establishing tubular structure and seal tubular structure's one end for when the air current flows through the heat exchanger, the air current can not flow in by tubular structure's one end, and directly flows out by the other end, but must flow through tubular structure's lateral part, so, the air current can carry out abundant and even heat exchange with coil pipe 41, thereby has improved the heat transfer effect of heat exchanger.
With continued reference to fig. 2A-2C, in a preferred embodiment, the cylindrical structure includes an upstream end and a downstream end in the airflow direction, wherein the upstream end of the cylindrical structure is closed and the downstream end of the cylindrical structure is formed with an opening. It should be noted that the "airflow flowing direction" in the above description may be understood as the airflow flowing direction at the installation position of the heat exchanger, for example, for the heat exchanger disposed inside the indoor unit of the air conditioner, the "airflow flowing direction" may be understood as the airflow flowing direction from the air inlet to the air outlet of the indoor unit of the air conditioner.
By arranging the tubular structure in a structure that the upstream end is closed and the downstream end is provided with an opening, when the air flow blows to the heat exchanger, the air flow is firstly blocked by the upstream end and is uniformly dispersed to the side part of the tubular structure, enters the interior of the tubular structure from the side part of the tubular structure and finally flows out from the opening of the downstream end of the tubular structure, and the arrangement can be seen that the air flow is more uniformly dispersed to the side part of the tubular structure to be contacted with the coil pipe for heat exchange.
Further, as shown in fig. 2B and 2C, the coil 41 includes a plurality of straight pipe sections 411 connected end to end, and two adjacent straight pipe sections 411 are connected by a bent pipe section 412. The plurality of straight tube sections 411 are distributed at intervals in the circumferential direction of the cylindrical structure, and the axes of the plurality of straight tube sections 411 are parallel to each other. Each straight tube section 411 has a plurality of fins 42 distributed at intervals in the axial direction thereof, wherein the fins 42 extend outwardly in the circumferential direction of the straight tube section 411, and the fins 42 of adjacent straight tube sections 411 are connected to each other in the circumferential direction of the tubular structure to form an annular structure.
By arranging the plurality of straight tube sections 411 of the coil 41 to be distributed at intervals along the axial direction of the tubular structure and the axes of the plurality of straight tube sections 411 to be parallel to each other, the plurality of straight tube sections 411 of the coil 41 are uniformly distributed on the side of the tubular structure, which is helpful for improving the heat exchange efficiency. By connecting the fins 42 of the adjacent straight tube sections 411 to each other in the circumferential direction of the tubular structure to form an annular structure, the heat dissipation area of the fins 42 can be increased, so that the air flow can be in sufficient contact with the fins 42, and the heat exchange effect is improved.
Of course, the above preferred embodiments are only used for illustrating the principles of the present invention, and are not intended to limit the scope of the present invention, and those skilled in the art can adjust the above setting mode so that the present invention can be applied to more specific application scenarios.
For example, in practical applications, the closed end of the cylindrical structure may be an upstream end or a downstream end. The arrangement can be made reasonably by those skilled in the art as long as it ensures that one of the two ends of the tubular structure of the heat exchanger is a closed end and the other end is an open end.
For another example, the coil 41 of the heat exchanger of the present invention may adopt other structural forms besides the structural form that the plurality of straight tube sections 411 are distributed at intervals along the circumferential direction of the tubular structure and the axes of the plurality of tube sections are parallel to each other in the above example, and those skilled in the art can flexibly set the structural form of the coil 41 according to the actual application scenario.
For another example, the arrangement of the fins 42 on each tube segment is not limited to the above example, and other arrangements are possible, and those skilled in the art can reasonably set the arrangement of the fins 42 according to actual needs. As in another alternative embodiment, each straight tube section 411 has a plurality of fins 42 spaced axially therealong, and the fins 42 of adjacent straight tube sections 411 are staggered circumferentially of the tubular structure. Through the arrangement, the heat dissipation area of the fins can be increased, and heat can be conducted in a staggered mode, so that the heat exchange effect is improved.
It is understood that the above alternative embodiments, and the alternative embodiments and the preferred embodiments can be used in a cross-matching manner, so that new embodiments can be combined to be suitable for more specific application scenarios.
