Description

Technical Field

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] Figure 1 This is a structural schematic diagram of an embodiment of the heat exchanger of the utility model; Figure 2 A cross-sectional schematic diagram of an embodiment of the heat exchanger of the utility model; Figure 3 It is a cross-sectional schematic diagram of another embodiment of the heat exchanger of the utility model; Figure 4 The schematic diagram of the structure of the airflow driving member of an embodiment of the heat exchanger of the utility model is shown in FIG. In the embodiment of the utility model, the heat exchanger 100 has a first surface 101 and a second surface 102 which are located on the circumference of the heat exchanger 100 and are arranged opposite to each other, and the plane where the first surface 101 is located and the plane where the second surface 102 is located have an angle.

[0042] The heat exchanger 100 includes a first fin assembly 110, a second fin assembly 120, and at least one airflow driving member 130. The first fin assembly 110 and the second fin assembly 120 are respectively arranged on the first surface 101 and the second surface 102, and the distance between the first fin assembly 110 and the second fin assembly 120 gradually decreases from the top of the heat exchanger 100 to the direction away from the heat exchanger 100. The airflow driving member 130 is arranged on the top of the heat exchanger 100 and can drive the external airflow to flow from the top of the heat exchanger 100 into the space between the first fin assembly 110 and the second fin assembly 120, and then flow out from the fin gap of the first fin assembly 110 and the fin gap of the second fin assembly 120.

[0043] In this embodiment, the first fin assembly 110 is installed on the first surface 101, and the second fin assembly 120 is installed on the second surface 102. The first fin assembly 110 and the second fin assembly 120 have a plurality of fins arranged at intervals, so that the inside and the outside of the heat exchanger 100 are connected. After the airflow flows into the top of the heat exchanger 100, it can flow out from the first fin assembly 110 and the second fin assembly 120 on both sides to achieve heat exchange.

[0044] The heat pump 200 in the prior art needs to be arranged with a pipe 220 to guide the external airflow into the heat exchanger 100, which causes the heat pump 200 to occupy a large space during installation and cannot be smoothly installed when the building has a low floor height. The heat exchanger 100 of the present application installs the airflow driving component 130 on the top of the heat exchanger 100, so that the airflow driving component 130 can drive the airflow to flow directly into the heat exchanger 100, and there is no need to install a pipe 220 to guide the airflow, which reduces the floor height requirement of the heat exchanger 100 and improves the compatibility of the heat exchanger 100 with buildings of different floor heights. Among them, the airflow driving component 130 can be a device such as a blower or a fan that can drive the airflow to flow.

[0045] In this embodiment, the first surface 101 and the second surface 102 are inclined relative to the vertical direction, so that the spacing between the first fin assembly 110 and the second fin assembly 120 gradually decreases from close to the top of the heat exchanger 100 to the direction away from the heat exchanger 100, and the windward surface of the first fin assembly 110 and the windward surface of the second fin assembly 120 face the top of the heat exchanger 100, so that the airflow flowing into the heat exchanger 100 from the top of the heat exchanger 100 can flow out smoothly from the first fin assembly 110 and the second fin assembly 120.

[0046] The heat exchanger 100 of the embodiment of the utility model sets the fan at the top of the heat exchanger 100, so that the external airflow can flow into the heat exchanger 100 from the top of the heat exchanger 100, and then flow out evenly from the first fin assembly 110 and the second fin assembly 120 on both sides of the heat exchanger 100. Compared with the air intake method in which the fan directly blows the external airflow to the windward surface of the first fin assembly 110 and the second fin assembly 120, after the external airflow flows into the heat exchanger 100 from the top, it can flow out evenly from the first fin assembly 110 and the second fin assembly 120 on both sides, thereby improving the heat exchange efficiency of the heat exchanger 100 and reducing the wind noise generated by the fins. In addition, by setting the fan at the top of the heat exchanger 100, the fan can be kept away from the crowd activity area, further reducing the impact of noise on people's lives.

[0047] In some embodiments, the airflow driving member 130 includes a plurality of blades 131, and the ratio of the distance between the first fin assembly 110 and the second fin assembly 120 away from the top side of the heat exchanger 100 to the diameter of the circular surface formed when the blades 131 rotate is 0.05 to 0.35.

[0048] In this embodiment, the distance between the first fin assembly 110 and the second fin assembly 120 away from the top side of the heat exchanger 100 is L, and the diameter of the circular surface formed when the fan blade 131 rotates is M, that is, the ratio of L to M is 0.05 to 0.35. When the ratio of L to M is within the range of 0.05 to 0.35, the airflow flowing into the heat exchanger 100 can be guided to the outside of the heat exchanger 100 by the first fin assembly 110 and the second fin assembly 120 to the greatest extent, so as to improve the airflow uniformity on the windward surface of the first fin assembly 110 and the second fin assembly 120.

[0049] In some embodiments, Figure 4 As shown, at least a portion of the edge of the blade 131 has an uneven serrated structure.

[0050] When the fan blade 131 rotates, the serrated structure at the edge of the fan blade 131 can form a shear layer, so that the air and the surface of the fan blade 131 generate more friction, increase the resistance of the blade surface, and thus increase the momentum transferred between the fan blade 131 and the air. In addition, the serrated structure generates vortices when the fan blade 131 rotates, which is conducive to reducing the flow rate of the airflow, making the airflow flowing into the heat exchanger 100 more uniform, thereby improving the heat exchange efficiency of the heat exchanger 100.

[0051] Furthermore, the serrated structure of the edge of the blade 131 can also reduce noise and vibration. Since the serrated structure can generate eddy currents when the blade 131 rotates, the airflow flowing into the heat exchanger 100 is more uniform, thereby reducing the wind noise generated by the blade 131, thereby reducing the generation of noise and vibration.

[0052] In some embodiments, the angle between the plane where the first surface 101 is located and the plane where the second surface 102 is located is an acute angle.

[0053] In this embodiment, since the first fin assembly 110 is installed on the first surface 101 and the second fin assembly 120 is installed on the second surface 102 , the angle between the plane where the first fin assembly 110 is located and the plane where the second fin assembly 120 is located is also an acute angle.

[0054] When the angle between the plane where the first fin assembly 110 is located and the plane where the second fin assembly 120 is located is an obtuse angle, since the inclination angle of the first fin assembly 110 and the second fin assembly 120 is too large, the airflow flowing into the interior of the heat exchanger 100 from the top of the heat exchanger 100 cannot pass through some fins of the first fin assembly 110 and the second fin assembly 120, resulting in insufficient uniformity of the windward surfaces of the first fin assembly 110 and the second fin assembly 120.

[0055] When the angle between the plane where the first fin assembly 110 is located and the plane where the second fin assembly 120 is located is an acute angle, each position of the windward surface of the first fin assembly 110 and the second fin assembly 120 can receive the airflow flowing from the top of the heat exchanger 100 into the interior of the heat exchanger 100, and the airflow uniformity on the windward surface of the first fin assembly 110 and the second fin assembly 120 is greatly improved compared to when the angle is an obtuse angle.

[0056] Preferably, the angle between the plane where the first surface 101 is located and the plane where the second surface 102 is located is 20° to 80°.

[0057] In this embodiment, when the angle between the plane where the first surface 101 is located and the plane where the second surface 102 is located is 20° to 80°, the airflow on the windward surface of the first fin assembly 110 and the second fin assembly 120 is most uniform, the wind noise generated by the fins is minimal, and the heat exchange efficiency of the heat exchanger 100 is highest.

[0058] like Figure 3 As shown, in some embodiments, the heat exchanger 100 further includes a third surface 103 and a fourth surface 104 vertical to the ground. The third surface 103 and the fourth surface 104 are arranged opposite to each other, one side of the third surface 103 is connected to the first surface 101, and the other side is connected to the top of the heat exchanger 100, and one side of the fourth surface 104 is connected to the second surface 102, and the other side is connected to the top of the heat exchanger 100, so that an air duct A1 is formed between the top of the heat exchanger 100 and the first surface 101 and the second surface 102.

[0059] In this embodiment, after the airflow driving member 130 drives the external airflow to flow into the heat exchanger 100, the airflow first passes through the air duct A1 and then flows to the windward surface of the first fin assembly 110 and the second fin assembly 120. After the airflow flows into the heat exchanger 100, the air duct A1 can play a role in buffering the airflow, preventing the airflow with too fast flow rate from directly blowing to the windward surface of the first fin assembly 110 and the second fin assembly 120, resulting in excessive fin noise. At the same time, by setting the air duct A1 between the first fin assembly 110, the second fin assembly 120 and the top of the heat exchanger 100, the airflow can be guided to flow evenly to the windward surface of the first fin assembly 110 and the second fin assembly 120 to improve the heat exchange efficiency of the heat exchanger 100.

[0060] In some embodiments, the length of the air duct A1 extending in a direction perpendicular to the ground is 20 mm to 230 mm.

[0061] In this embodiment, the length of the air duct A1 can be selected according to the wind force generated by the airflow driving component 130. The larger the range of the airflow generated by the airflow driving component 130 and the faster the airflow velocity, the longer the length of the air duct A1. Conversely, the shorter the length of the air duct A1.

[0062] In some embodiments, the first fin assembly 110 and the second fin assembly 120 have the same length from a side close to the top of the heat exchanger 100 to a side far from the top of the heat exchanger 100 .

[0063] The length of the air duct A1 is set to be selected based on the length of the first fin assembly 110, the second fin assembly 120, and the angle between the plane where the first surface 101 is located and the plane where the second surface 102 is located.

[0064] In this embodiment, the length of the air duct A1 is obtained based on the following formula: D = HH × cos (α / 2) - 62.6. Wherein, D is the length of the air duct A1, H is the length of the first fin assembly 110 and the second fin assembly 120 from the side close to the top of the heat exchanger 100 to the side away from the top of the heat exchanger 100, α is the angle between the windward surface of the first fin assembly 110 and the windward surface of the second fin assembly 120, and the size of D is in the range of 20 mm to 230 mm.

[0065] Figure 5 This is a schematic structural diagram of a flow guide member of an embodiment of a heat exchanger of the utility model; Figure 6 This is a schematic structural diagram of a flow guide member of another embodiment of a heat exchanger of the utility model.

[0066] In some embodiments, the heat exchanger 100 also includes a guide member 140, which extends in a direction vertical to the top of the heat exchanger 100, and the two surfaces of the guide member 140 are respectively arranged opposite to the third surface 103 and the fourth surface 104; the air duct A1 is divided into two parts by the guide member 140, and the airflow generated by the airflow driving member 130 flows to the first fin assembly 110 and the second fin assembly 120 through the two parts of the air duct A1.

[0067] In this embodiment, one end of the guide member 140 is connected to the top of the heat exchanger 100. Since the guide member 140 is located in the middle position of the top of the heat exchanger 100, the air duct A1 is divided into two parts by the guide member 140. The airflow generated by the airflow driving member 130 is respectively guided to the windward surface of the first fin assembly 110 and the windward surface of the second fin assembly 120 through the two divided air ducts A1 to improve the heat exchange efficiency of the heat exchanger 100.

[0068] In some embodiments, one end of the guide member 140 is connected to the top of the heat exchanger 100, and the other end is connected to the bottom of the heat exchanger 100, and the guide member 140 is located between the first fin assembly 110 and the second fin assembly 120, a portion of the airflow generated by the airflow driving member 130 is directed to the surface of the first fin assembly 110, and another portion of the airflow is directed to the surface of the second fin assembly 120.

[0069] In this embodiment, the guide member 140 completely divides the interior of the heat exchanger 100 into two parts, so that the airflow generated by the airflow driving member 130 is evenly divided, half of which flows to the windward surface of the first fin assembly 110, and the other half flows to the windward surface of the second fin assembly 120. The guide member 140 can prevent the airflow from flowing back and forth inside the heat exchanger 100 to generate disturbances or eddies, and the guide member 140 can improve the heat exchange efficiency of the heat exchanger 100 by smoothly guiding the airflow to the first fin assembly 110 and the second fin assembly 120.

[0070] Figure 7 This is a schematic structural diagram of an embodiment of the heat pump machine of the utility model; Figure 8 The utility model further provides a heat pump 200, which comprises: a heat exchanger 100 of any of the above embodiments of the utility model, a compressor 210, a plurality of pipes 220 and a controller 230.

[0071] The compressor 210 can compress the refrigerant medium and drive the refrigerant medium to circulate. The pipeline 220 is used to transport gaseous medium, liquid medium or refrigerant medium. The controller 230 is electrically connected to the airflow driving component 130 and the compressor 210. The controller 230 is configured to control the start and stop of the airflow driving component 130 and the compressor 210.

[0072] The heat exchanger 100 has a first surface 101 and a second surface 102 which are located on the circumference of the heat exchanger 100 and are arranged opposite to each other. The plane where the first surface 101 is located and the plane where the second surface 102 is located have an angle.

[0073] The heat exchanger 100 includes a first fin assembly 110, a second fin assembly 120 and at least one airflow driving member 130. The first fin assembly 110 and the second fin assembly 120 are respectively arranged on the first surface 101 and the second surface 102, so that the distance between the first fin assembly 110 and the second fin assembly 120 gradually increases or decreases from one side to the other side. The airflow driving member 130 is arranged on the top of the heat exchanger 100 and can drive the external airflow to flow from the top of the heat exchanger 100 into the space between the first fin assembly 110 and the second fin assembly 120, and then flow out from the gap between the first fin assembly 110 and the second fin assembly 120.

[0074] In this embodiment, the compressor 210 can control the refrigerant medium to change from low temperature and low pressure to high temperature and high pressure, and circulate the refrigerant medium through the pipeline 220 to achieve heat release. The airflow driving member 130 can drive the external airflow to flow into the heat exchanger 100 from the top of the heat exchanger 100, and then flow out from the first fin assembly 110 and the second fin assembly 120 on both sides of the heat exchanger 100 to achieve cold and heat exchange.

[0075] The controller 230 can control the start and stop of the airflow driving element 130 and the compressor 210 and the power level, thereby controlling the power, air intake volume and other parameters of the heat pump 200 .

[0076] The heat pump 200 of the embodiment of the utility model includes a heat exchanger 100. The heat exchanger 100 sets a fan at the top of the heat exchanger 100, so that the external airflow can flow into the heat exchanger 100 from the top of the heat exchanger 100, and then flow out evenly from the first fin assembly 110 and the second fin assembly 120 on both sides of the heat exchanger 100. Compared with the air intake method in which the fan directly blows the external airflow to the windward surface of the first fin assembly 110 and the second fin assembly 120, after the external airflow flows into the heat exchanger 100 from the top, it can flow out evenly from the first fin assembly 110 and the second fin assembly 120 on both sides, thereby improving the heat exchange efficiency of the heat exchanger 100 and reducing the wind noise generated by the fins. In addition, by setting the fan at the top of the heat exchanger 100, the fan can be far away from the crowd activity area, further reducing the impact of noise on people's lives, so that the heat pump 200 can reduce the impact of noise on people while improving the uniformity of the fin air intake.

[0077] In some embodiments, the heat pump machine 200 further includes a support frame 240. The heat exchanger 100, the compressor 210, the pipeline 220 and the controller 230 are arranged on the support frame 240, and the support frame 240 includes a plurality of connecting beams 241 and a plurality of connecting columns 242, and the connecting beams 241 and the connecting columns 242 are connected to each other through a tongue-and-groove structure to form the support frame 240.

[0078] Specifically, the connecting beam 241 and the connecting column 242 are hollow, and the two ends of the connecting beam 241 are provided with openings for connecting the connecting column 242. The two ends of the connecting column 242 are provided with limiting structures matching the openings. The two ends of the connecting column 242 can extend into the openings of the connecting beam 241 and be clamped with the connecting beam 241 through the limiting structure, so that the connecting beam 241 and the connecting column 242 can be detachably connected to form a tongue and groove structure.

[0079] In this embodiment, the connecting beam 241 and the connecting column 242 have a tongue-and-groove structure that matches each other, and the connecting beam 241 and the connecting column 242 can be detachably connected through the tongue-and-groove structure. A plurality of connecting beams 241 and connecting columns 242 are connected and assembled through the tongue-and-groove structure, so that the supporting frame 240 can be formed between the connecting beams 241 and the connecting columns 242 without welding, thereby greatly speeding up the assembly speed of the supporting frame 240, improving production efficiency, and facilitating disassembly and maintenance.
