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.

Through adopting digital turbine motor as air supply fan 3 for the wind-force of air conditioner is powerful, and the air output is big, satisfies the demand that the user refrigerates fast and heats.

Referring to fig. 1, 3A and 3B, a specific embodiment of the annular air outlet structure will be described. Fig. 3A is a cross-sectional view of the annular air outlet structure of the present invention in a first air outlet manner; fig. 3B is a cross-sectional view of the annular air outlet structure in the second air outlet mode.

As shown in fig. 1, fig. 3A and fig. 3B, the annular air outlet structure 12 includes an inner annular surface 121 and an outer annular surface 122, the outer annular surface 122 is disposed outside the inner annular surface 121 and surrounds the inner annular surface 121 to form an air outlet cavity, a first air outlet 123 is formed at a front end of the outer annular surface 122 (i.e., at a right end of the outer annular surface 122 in fig. 3A) and a front end of the inner annular surface 121 (i.e., at a right end of the inner annular surface 121 in fig. 3A), a second air outlet 124 is formed at a side surface of the outer annular surface 122, and a rear end of the outer annular surface 122 is connected to a rear end of the inner. The first outlet 123 is configured with a first flap mechanism 125, and the first flap mechanism 125 can selectively open or close the first outlet 123. Similarly, a second blocking mechanism 126 is disposed at the second air outlet 124, and the second blocking mechanism 126 can selectively open or close the second air outlet 124. The bottom end of the outer annular surface 122 is further provided with a vent hole (not shown in the figure), and after the annular air outlet structure 12 is fixedly connected to the cylindrical shell 11, the air outlet cavity is communicated with the cylindrical shell 11 through the vent hole. The humidifier 2 includes a water tank 21 and an atomizer 22 disposed in the water tank 21, the atomizer 22 may be an ultrasonic atomizer or an air compression atomizer, and the water tank 21 is fixedly connected to the bottom of the inner annular surface 121, and the atomizer 22 can atomize the liquid in the water tank 21 into water mist.

It can be understood by those skilled in the art that although not specifically shown in the drawings of the present embodiment, the first flap mechanism 125 and the second flap mechanism 126 may be implemented in various forms as long as the arrangement is effective to control the opening and closing of the first outlet port 123 and the second outlet port 124. For example, the first flap mechanism 125 and/or the second flap mechanism 126 may be implemented by controlling an annular collar with a linear motor, and the linear motor drives the annular collar to move back and forth in the air outlet cavity to implement opening and closing control of the first air outlet 123 and/or the second air outlet 124; or the linear motor can be replaced by a combination of a rotary motor, a gear rack, a chain and the like. For another example, the first flap mechanism 125 and/or the second flap mechanism 126 may control the opening and closing of the second air outlet 124 through electromagnetic absorption, that is, the retainer ring is made of a metal material, an electromagnetic coil is disposed in the air outlet cavity, an elastic element is disposed between the retainer ring and the inner annular surface 121 or the outer annular surface 122, when the electromagnetic coil is powered on, the electromagnetic coil generates magnetic force to attract the retainer ring, and the elastic element stores elastic potential energy, so as to open the first air outlet 123 or the second air outlet 124; when the electromagnetic coil is powered off, the retainer ring returns to the initial position under the action of the elastic piece to close the first air outlet 123 or the second air outlet 124. For another example, one of the first flap mechanism 125 and the second flap mechanism 126 may be omitted, and selective opening of any one of the first air outlet 123 and the second air outlet 124 may be achieved only by controlling movement of the one flap mechanism.

Further preferably, an air guiding structure is further disposed on the inner annular surface 121 and/or the outer annular surface 122, and the air guiding structure is configured to gradually reduce the air outlet width at the air outlet. For example, the wind guiding structure adopts two arc plates as shown in fig. 3A or 3B, and the arrangement of the two arc plates gradually narrows the outlet widths of the first air outlet 123 and the second air outlet 124, so that when the air flow passes through the air outlet, a venturi effect is generated to accelerate the flow velocity, thereby realizing the spraying effect. When the air is sprayed, negative pressure is generated near the annular air outlet, and the negative pressure can attract air near the annular air outlet to flow together, so that the circulation of indoor air is realized, and the air supply quantity is effectively improved. Of course, the air guiding structure may also be any other arrangement manner as long as the arrangement manner can gradually narrow the air outlet width of the first air outlet 123 and/or the second air outlet 124, and details are not repeated herein.

The spraying mode can realize the spraying air-out effect, the spraying range is far, and the air outlet quantity is larger; the diffusion mode is that the second air outlet 124 supplies air to two sides, the air supply area is wide, airflow can be formed indoors in an encircling mode, and circulation of indoor air is enhanced. In addition, the arrangement of the annular air outlet enables the air conditioner to be novel in structure, the iterative sealing idea of the traditional cabinet type air conditioner product is subverted, and the development change of the air conditioner is promoted. Through the bottom with water tank 21 fixed connection at interior annular surface 121 for the water smoke behind the atomizer 22 atomizing can be directly sent to indoor each corner with the air current mixture of air outlet exhaust, guarantees the humidification effect.
