Example Embodiment

[0039] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0040] The uniformity of the wind speed (air volume) distribution on the surface of the heat exchange device has a significant impact on the heat exchange performance of the heat exchange device. Traditionally, for a generally inverted V-shaped heat exchange device, an air guiding component is arranged inside the heat exchange device so that the wind speed is evenly distributed on the heat exchange device. However, the inventor of the present application found that, due to the different heat transfer coefficients of the refrigerant in different regions of the heat exchanger, the heat exchange capabilities of the refrigerant in different regions of the heat exchanger are different. Therefore, the air volume is evenly distributed on the heat exchange device, which will result in insufficient air volume matching in areas with strong heat exchange capacity, and excessive air volume in areas with weak heat exchange capacity, which affects the heat exchange capacity of the heat exchange device. Based on the above findings, the applicant proposes a heat exchange device whose heat exchange capacity is improved.

[0041] Reference below Figure 1-Figure 16 The heat exchange device 1 according to the embodiment of the present invention is described.

[0042] Such as Figure 1-Figure 16 As shown, the heat exchange device 1 according to the embodiment of the present invention includes a first heat exchanger 100, a second heat exchanger 200, and a wind guide member 300.

[0043] The upper end of the first heat exchanger 100 is connected to the upper end of the second heat exchanger 200, the lower end of the first heat exchanger 100 and the lower end of the second heat exchanger 200 are spaced apart in the longitudinal direction X, and the first heat exchanger 100 and The second heat exchanger 200 forms a predetermined included angle θ, where 0

[0044] The inner surface of the first heat exchanger 100 ( figure 1 The right side surface of the first heat exchanger 100) and the inner surface of the second heat exchanger 200 ( figure 1 The left side surface of the second heat exchanger 200) are opposite to each other. The lower end of the first heat exchanger 100 is provided with a refrigerant inlet 110, and the lower end of the second heat exchanger 200 is provided with a refrigerant outlet 210. The space defined by the first heat exchanger 100 and the second heat exchanger 200 and the plane defined by the lower ends of the first heat exchanger 100 and the second heat exchanger 200 may be referred to as the inner cavity of the heat exchange device.

[0045] The first heat exchanger 100 and the second heat exchanger 200 may be formed by bending a single flat heat exchanger, or may be formed by connecting two independent flat heat exchangers.

[0046] When the first heat exchanger 100 and the second heat exchanger 200 are two independent flat plate heat exchangers, the upper end of the first heat exchanger 100 is connected to the upper end of the second heat exchanger 200, and the connection should be broadly defined here. It is understood that as long as the upper ends of the first heat exchanger 100 and the second heat exchanger 200 are adjacent and communicate with each other and form a substantially inverted V-shaped heat exchange device. For example, the upper end of the first heat exchanger 100 can be directly connected with the upper end of the second heat exchanger 200 or connected by a connecting piece. As another example, the upper end of the first heat exchanger 100 and the upper end of the second heat exchanger 200 can be shared A collector.

[0047] The air guide member 300 is located between the first heat exchanger 100 and the second heat exchanger 200 and is closer to the second heat exchanger 200 than to the first heat exchanger 100. In other words, the wind guide member 300 may be arranged between the inner surface of the first heat exchanger 100 and the inner surface of the second heat exchanger 200 (that is, arranged in the inner cavity of the heat exchange device 1), and the wind guide member 300 is opposite to The inner surface of the first heat exchanger 100 is closer to the inner surface of the second heat exchanger 200. For a better understanding, for example, the opening of the heat exchange device 1 is set downwards. In a horizontal plane, the area where the projection of the wind guide member 300 overlaps with the projection of the second heat exchanger 200 is larger than the projection of the wind guide member 300 and the second heat exchanger 200. An area where the projections of the heat exchanger 100 overlap.

[0048] By arranging the air guide member 300 as described above, the distribution of the air volume on the first heat exchanger 100 and the second heat exchanger 200 can be adjusted, and the air volume and wind speed reaching the area where the heat transfer coefficient of the heat exchange device is large are large, and The air volume and wind speed in the area where the heat exchange coefficient of the heat exchange device is small is small, thereby improving the heat exchange capacity of the heat exchange device and improving the heat exchange efficiency. In other words, the air volume is matched with the heat exchange capacity of the refrigerant, so that more wind passes through areas with strong heat exchange capacity faster, and less wind passes through areas with weak heat exchange capacity slower, which can greatly increase the exchange rate. The heat exchange capacity of the heat device 1.

[0049] Figure 4 Shows a curve comparison between the wind speed change through the heat exchange device 1 according to the embodiment of the present invention and the wind speed change through two traditional heat exchange devices, of which two traditional heat exchange devices, one is not provided with wind guide components The heat exchange device is another type of heat exchange device with symmetrically arranged air guiding components. From Figure 4 It can be seen that the wind speed in the middle of the heat exchange device (the top of the inner cavity of the inverted V-shaped heat exchange device) is the highest in the heat exchange device without the air guide component. The heat exchange device with symmetrical air guiding parts, the wind speed at both ends of the heat exchange device is small, and the wind speed in the middle part is uniform and large. According to the heat exchange device 1 of the embodiment of the present invention, the wind guide member 300 is arranged off-center and close to the second heat exchanger 200. In the direction from the refrigerant inlet to the refrigerant outlet, the upstream area of the heat exchange device (close to the refrigerant The wind speed in the area of the inlet 110 is uniform and large, and the wind speed in the downstream area (the area close to the refrigerant outlet 210) is small, so the wind speed can be exchanged with each area of the first heat exchanger 100 and the second heat exchanger 200 The matching of the thermal capacity improves the overall heat exchange capacity of the heat exchange device 1.

[0050] Figure 5 A columnar comparison diagram of the heat exchange capacity and wind pressure of the wind field between the heat exchange device 1 according to the embodiment of the present invention and two conventional heat exchange devices is shown. Among them, there are two kinds of traditional heat exchange devices, one is a heat exchange device without air guiding parts, and the other is a heat exchange device with symmetrical air guiding parts. From Figure 5 It can be seen that according to the heat exchange device 1 of the embodiment of the present invention, the air guide member 300 is arranged off-center and close to the second heat exchanger 200, which can make the main heat exchange area of the heat exchange device fully carry out heat exchange, which greatly improves The heat exchange capacity Q of the heat exchange device 1. At the same time, placing the wind guide member 300 at an off-center position of the heat exchange device has less disturbance to the airflow than the wind guide member of the traditional heat exchange device. Therefore, the generated wind field pressure drop ΔP is small.

[0051] It is understandable that the heat exchange device 1 according to the embodiment of the present invention may be composed of a first heat exchanger 100 and a second heat exchanger 200 to form a substantially inverted V shape, and may also be composed of multiple flat plate heat exchangers or one flat plate heat exchanger. The heat exchanger is bent multiple times to form other shapes including an inverted V shape. For example, the heat exchange device 1 according to the embodiment of the present invention may be connected by three flat heat exchangers or a flat heat exchanger can be bent twice to form a general N shape. For another example, the heat exchange device 1 may consist of four flat heat exchangers. The heat exchanger is connected or a flat plate heat exchanger is bent three times to form a general M or W shape.

[0052] In some embodiments of the present invention, the lower end of the first heat exchanger 100 and the lower end of the second heat exchanger 200 are flush. For example, the first heat exchanger 100 and the second heat exchanger 200 may be symmetrical with respect to the angular bisecting plane between the first heat exchanger 100 and the second heat exchanger 200.

[0053] In some embodiments of the present invention, the wind guide member 300 may be disposed in a predetermined area adjacent to the refrigerant outlet 210. For example, in the horizontal plane, the projection of the wind guide member 300 may be completely located within the projection of the second heat exchanger 200. That is to say, taking the angular bisector of the included angle θ between the first heat exchanger 100 and the second heat exchanger 200 as the dividing line, the air guide member 300 may be arranged on the angular bisector adjacent to the second heat exchanger 200 Side. In this way, the wind guide member 300 can be used to block the air volume at the refrigerant outlet 210, so that the air volume is blown to other areas more.

[0054] The heat exchange device 1 according to specific embodiments of the present invention will be described below with reference to the drawings.

[0055] In the description of the following embodiments, for ease of description, the first heat exchanger 100 is divided into two sections, where the one adjacent to the refrigerant inlet 110 is the first lower heat exchange section I, and the other section is the first upper heat exchange section II. . Similarly, the second heat exchanger 200 is divided into two sections, where the second lower heat exchange section IV is adjacent to the refrigerant outlet 210, and the other section is the second upper heat exchange section III.

[0056] Such as figure 1 As shown, the heat exchange device 1 according to this embodiment of the present invention includes a first heat exchanger 100, a second heat exchanger 200, and a wind guide member 300. The wind guide member 300 is a flat plate and is arranged obliquely with respect to the horizontal direction. The first heat exchanger 100 and the second heat exchanger 200 are formed by bending a flat plate heat exchanger. The lower end of the first heat exchanger 100 is provided with a refrigerant inlet 110, and the lower end of the second heat exchanger 200 is provided with refrigeration 剂 Exit 210.

[0057] Such as figure 1 As shown, the angle between the wind guide member 300 and the horizontal direction is β, the vertical distance between the upper end of the wind guide member 300 and the lower end of the wind guide member 300 is H2, and the lower end of the wind guide member 300 and The distance between the lower end of the second heat exchanger 200 in the horizontal direction is L1, and the connection line between the lower end of the first heat exchanger 100 and the lower end of the second heat exchanger 200 and the lower end of the wind guide member 300 are in the vertical direction The distance above is H1, where 0.2≤(H1+H2)/H <1, 0≤L1/L <0.5, 0°≤β≤90°-θ/2.

[0058] Such as Figure 7 As shown, optionally, the wind guide member 300 is a corrugated plate, that is, the cross section of the wind guide member 300 is composed of multiple arcs. The wind guide member 300 is arranged obliquely between the first heat exchanger 100 and the second heat exchanger 200 and is closer to the second heat exchanger 200, that is, the lower end of the wind guide member 300 is closer to the second heat exchanger than the upper end of the wind guide member 300 Heat exchanger 200. The wind guide member 300 adopts a corrugated plate, which can guide the air flow to the first heat exchanger 100 multiple times.

[0059] Such as Figure 8 As shown, in an optional example, the wind guide member 300 is an arc-shaped plate and is arranged obliquely adjacent to the second heat exchanger 200, and the middle of the wind guide member 300 may protrude toward the first heat exchanger 100. In this embodiment, the windward area of the arc-shaped wind guide member 300 is small, so that the generated wind field pressure drop can be reduced.

[0060] Such as Image 6 As shown, in another specific implementation of the present invention, the wind guide member 300 may be a flat plate arranged obliquely and connected to the lower end of the second heat exchanger 200. Specifically, the lower end of the wind guide member 300 may be connected to a collecting pipe forming the refrigerant outlet 210. The distance in the horizontal direction between the lower end of the first heat exchanger 100 and the lower end of the second heat exchanger 200 is L, the length of the air guide member 300 is L2, and the distance between the air guide member 300 and the second heat exchanger 200 The included angle is γ, where 0

[0061] In this example, since the wind guide member 300 is connected to the second heat exchanger 200 at the refrigerant outlet 210, the generated wind field pressure drop can be reduced. In addition, the fins in the area of the second lower heat exchange section IV are usually dense, and more condensed water is formed on the fins in this area. The air guiding member 300 is arranged in this area to prevent the condensation water from falling into the air duct.

[0062] In some specific embodiments of the present invention, the wind guide member 300 may also be a V-shaped plate, such as figure 2 with Figure 9-16 As shown, the flat plate heat exchanger is bent to form the first heat exchanger 100 and the second heat exchanger 200. The angle between the first heat exchanger 100 and the second heat exchanger 200 is an acute angle, and the first heat exchanger The lower end of the second heat exchanger 200 is provided with a refrigerant inlet 110, and the lower end of the second heat exchanger 200 is provided with a refrigerant outlet 210. The wind guide member 300 is arranged between the first heat exchanger 100 and the second heat exchanger 200 and is adjacent to the second heat exchanger. Heat exchanger 200.

[0063] The air guide member 300 includes a first plate leg 310 and a second plate leg 320. The lower end of the first plate leg 310 and the lower end of the second plate leg 320 are connected to each other, that is, the opening of the V-shaped plate faces upward, and the second plate leg 320 is more The first leg 310 is closer to the second heat exchanger 200. As a result, the air volume will be divided into two air streams from the bottom of the V-shaped plate, and flow upwards along both sides of the V-shaped plate.

[0064] The angle between the first leg 310 and the second leg 320 is α, the angle between the first leg 310 and the horizontal direction is β, the upper end of the second leg 320 and the lower end of the second leg 320 The distance between the vertical direction is H2, the horizontal distance between the lower end of the first plate leg 310 and the second plate leg 320 and the lower end of the second heat exchanger 200 is L1, the first heat exchanger The vertical distance between the connecting line between the lower end of 100 and the lower end of the second heat exchanger 200 and the lower ends of the first plate leg 310 and the second plate leg 320 is H1. Among them, 0.2≤[H1+H2]/H <1, 0 <0.5, 0° <90°.

[0065] Such as figure 2 As shown, the air guide member 300 can be formed by bending a flat plate, or by connecting the lower ends of two separate flat plates, that is, the first plate leg 310 and the second plate leg 320 are both flat plates, and the second plate leg 320 is formed along the Extending in the vertical direction, the first leg 310 is inclined with respect to the horizontal direction. Specifically, the first plate leg 310 may extend upward and toward the first heat exchanger 100 from the lower end of the second plate leg 320. Such as figure 2 As shown, the wind passing from the left side of the air guiding member 300 will blow to the first lower heat exchange section I and the first upper heat exchange section II, and the wind passing from the right side of the air guiding member 300 will blow to the second upper heat exchange section. Hot section III.

[0066] In another embodiment of the present invention, such as Picture 9 As shown, the wind guide member 300 is formed by bending a flat plate, and the first plate leg 310 and the second plate leg 320 are both flat plates and are inclined relative to the horizontal direction. For example, to Picture 9 The left and right directions in the middle are subject, the lower end of the second leg 320 is inclined to the right compared to the upper end of the second leg 320, and the first leg 310 extends from the lower end of the second leg 320 to the left and upward. In this way, the air volume will be more concentratedly blown to the three areas of the first lower heat exchange section I, the first upper heat exchange section II and the second upper heat exchange section III under the guidance of the air guide member 300, which is beneficial to improve the heat exchange device 1. The heat transfer capacity.

[0067] In some embodiments of the present invention, the first limb 310 and the second limb 320 may also be curved plates. For example, such as Picture 10 As shown, the first leg 310 is an arc-shaped plate, the second leg 320 is a flat plate and extends in a vertical direction, and the first leg 310 is inclined with respect to the horizontal direction and protrudes toward the direction of the second leg 320. While the air guiding component 300 directs the air volume to the first lower heat exchange section I, the first upper heat exchange section II and the second upper heat exchange section III, the air volume in these three areas will be more concentrated in the heat transfer capacity The first lower heat exchange section I.

[0068] Of course, the first plate limb 310 may also protrude toward the direction of the first heat exchanger 100, such as Picture 11 As shown, on the one hand, the wind guide member 300 can guide the wind to the first lower heat exchange section I, the first upper heat exchange section II and the second upper heat exchange section III, and on the other hand, the arc structure of the first plate leg 310 is similar to The streamlines of the air flow are close, so the pressure drop of the wind field is smaller.

[0069] The first limb 310 and the second limb 320 can also be curved plates, such as Picture 12 As shown, the first plate leg 310 and the second plate leg 320 both protrude toward the direction of the second heat exchanger 200, the first plate leg 310 can guide the airflow to the first lower heat exchange section I, and the second plate leg The structure of 320 is close to the streamline of the airflow, which can make the wind field produce a smaller wind field pressure drop.

[0070] Such as Figure 13 As shown, the first plate leg 310 and the second plate leg 320 can also protrude toward the direction of the first heat exchanger 100, the second plate leg 320 can direct the airflow to the second upper heat exchange section III, and the first plate leg The limb 310 can guide the airflow to the first lower heat exchange section I and the first upper heat exchange section II, and the generated wind field pressure drop is small.

[0071] One of the first leg 310 and the second leg 320 may be an arc-shaped plate, and the other may be an arc-shaped plate composed of multiple arcs. For example, such as Figure 14 As shown, the second leg 320 may be an arc-shaped plate, and the first leg 310 may be composed of a first arc-shaped section 311 and a second arc-shaped section 312, the first arc-shaped section 311 and the second arc-shaped section 312 The projection direction is opposite. Specifically, the middle portion of the second plate leg 320 protrudes toward the second heat exchanger 200, the lower end of the second arc section 312 is connected to the lower end of the second plate leg 320, and the second arc section 312 faces the second plate leg 320 protrudes, the lower end of the first arc-shaped section 311 is connected with the upper end of the second arc-shaped section 312 and has a curve transition, and the second arc-shaped section 312 protrudes toward the first heat exchanger 100.

[0072] In some specific embodiments of the present invention, such as Figure 15 with Figure 16 As shown, the heat exchange device 1 includes a first heat exchanger 100, a second heat exchanger 200, and a wind guide member 300. The first heat exchanger 100 and the second heat exchanger 200 are bent by flat plate heat exchangers to form an opening. In the downward-facing inverted V shape, the lower end of the first heat exchanger 100 is provided with a refrigerant inlet 110, the lower end of the second heat exchanger 200 is provided with a refrigerant outlet 210, and the air guide member 300 is provided on the first heat exchanger 100 Between the second heat exchanger 200 and closer to the second heat exchanger 200, the air guide member 300 is composed of a first plate leg 310 and a second plate leg 320 connected at the lower end.

[0073] Such as Figure 15 As shown, the second plate leg 320 is a flat plate extending in a vertical direction. The first plate leg 310 includes a first plate section 313 and a second plate section 314. The lower end of the second plate section 314 and the lower end of the second plate leg 320 Connected, the lower end of the first plate section 313 is connected with the upper end of the second plate section 314 and bent toward the second plate leg 320, the angle between the first plate section 313 and the second plate section 314 is δ, 90°≤ δ <180°.

[0074] Optionally, the first leg 310 and the second leg 320 may also be bent flat plates. For example, such as Figure 16 As shown, each of the first plate leg 310 and the second plate leg 320 includes a first plate section 313 and a second plate section 314. The first plate section 313 of the second plate leg 320 extends in a vertical direction. The first plate section 313 of the second plate leg 320 is bent upward from the second plate section 314 of the second plate leg 320 toward the first plate leg 310, and the second plate section 314 of the first plate leg 310 is bent from the second plate leg 320 The second plate section 314 of the first plate leg 310 extends upward and toward the first heat exchanger 100, and the first plate section 313 of the first plate leg 310 is bent upward and toward the second plate leg 320 from the second plate section 314 of the first plate leg 310 . In other words, the first plate section 313 of the first plate leg 310 and the first plate section 313 of the second plate leg 320 are relatively bent.

[0075] Reference below Figure 1-Figure 16 The heat exchange device 1 according to another embodiment of the present invention is described.

[0076] Such as Figure 1-Figure 16 As shown, the heat exchange device 1 according to the embodiment of the present invention includes a first heat exchanger 100, a second heat exchanger 200, and a wind guide member 300.

[0077] The upper end of the first heat exchanger 100 is connected to the upper end of the second heat exchanger 200, the lower end of the first heat exchanger 100 and the lower end of the second heat exchanger 200 are spaced apart in the longitudinal direction X, and the first heat exchanger 100 and The second heat exchanger 200 forms a predetermined included angle θ, where 0

[0078] The inner surface of the first heat exchanger 100 ( figure 1 The right side surface of the first heat exchanger 100) and the inner surface of the second heat exchanger 200 ( figure 1 The left side surface of the second heat exchanger 200) are opposite to each other. The lower end of the first heat exchanger 100 is provided with a refrigerant inlet 110, and the lower end of the second heat exchanger 200 is provided with a refrigerant outlet 210. The space defined by the first heat exchanger 100 and the second heat exchanger 200 and the plane passing through the lower ends of the first heat exchanger 100 and the second heat exchanger 200 may be referred to as the inner cavity of the heat exchange device.

[0079] The air guide member 300 is located between the first heat exchanger 100 and the second heat exchanger 200, and the air flow guided by the air guide member 300 to the second heat exchanger 200 in a predetermined area adjacent to the refrigerant outlet 210 is less than that of the air guide member The air volume 300 guided to other areas on the second heat exchanger 200 and the air volume guided to the first heat exchanger 100 by the air guiding component 300. In other words, the wind guide member 300 can guide the flow direction of the wind to improve the distribution of the air volume in each area of the first heat exchanger 100 and the second heat exchanger 200. Specifically, after the wind is guided by the wind guide member 300, the air volume in the predetermined area adjacent to the refrigerant outlet 210 on the second heat exchanger 200 is less than the air volume in other areas on the second heat exchanger 200, and the second heat exchanger 200 The air volume in a predetermined area on the 200 adjacent to the refrigerant outlet 210 is smaller than the air volume on the first heat exchanger 100.

[0080] Since the refrigerant flows from the refrigerant inlet 110 through the first heat exchanger 100 and the second heat exchanger 200 to the refrigerant outlet 210, the temperature will gradually change, so that the heat exchange capacity of the refrigerant at the refrigerant outlet 210 is relatively weak . By providing the air guiding component 300, the air guiding component 300 is used to improve the distribution of the air volume on the first heat exchanger 100 and the second heat exchanger 200, so that the air volume at the refrigerant outlet 210 of the second heat exchanger 200 is smaller than that of the second heat exchanger 200. The air volume of other areas on the heat exchanger 200 and the air volume of the first heat exchanger 100 can match the air volume with the heat exchange capacity of the refrigerant, thereby improving the heat exchange capacity of the heat exchange device 1.

[0081] In a specific embodiment of the present invention, such as figure 1 As shown, the wind guide member 300 is a flat plate arranged obliquely with respect to the horizontal direction, and the wind guide member 300 is closer to the second heat exchanger 200 than the first heat exchanger 100.

[0082] The air flow F1 guided by the air guiding component 300 to the first lower heat exchange section I, the air flow F2 guided by the air guiding component 300 to the first upper heat exchange section II, and the air guiding component 300 to the second upper heat exchange section The air volume F3 on section III is greater than the air volume F4 guided by the air guiding component 300 to the second lower heat exchange section IV, that is, the air volume F1 at the first lower heat exchange section I and the air volume at the first upper heat exchange section II. F2, the air volume F3 at the second upper heat exchange section III is greater than the air volume F4 at the second lower heat exchange section IV. Because the heat exchange capacity of the refrigerant in the first lower heat exchange section I, the heat exchange capacity of the refrigerant in the first upper heat exchange section II, and the heat exchange capacity of the refrigerant in the second upper heat exchange section III are greater than those of the refrigerant The heat transfer capacity of the second lower heat exchange section IV, so that the air volume can be directed as far as possible to the first lower heat exchange section I, the first upper heat exchange section II and the second upper heat exchange section III three areas with strong heat exchange capacity , Which is beneficial to improve the heat exchange capacity of the heat exchange device 1.

[0083] According to the embodiment of the present invention, the air guide member 300 is placed in the area of the inverted V-shaped heat exchange device that is off-center and close to the refrigerant outlet 210 to guide the airflow blowing to the inverted V-shaped heat exchange device to make the first lower heat exchange section Ⅰ. The first upper heat exchange section II and the second upper heat exchange section III obtain larger wind speeds.

[0084] According to the substantially inverted V-shaped heat exchange device 1 of the embodiment of the present invention, an off-center position is set between the first heat exchanger 100 and the second heat exchanger 200 (for example, offset from the first heat exchanger 100 and the second heat exchanger). The angle bisecting plane between the heat exchanger 200) is arranged with the wind guide member 300, the wind guide member 300 can guide the wind to the area of the first heat exchanger 100 and the second heat exchanger 200 with strong heat exchange capacity, which improves the air volume The distribution makes the distribution of air volume match the change of refrigerant heat exchange parameters, and improves the heat exchange capacity.
