Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a V-shaped evaporator and an air conditioner. Background Art

[0002] The V-type evaporator is a type of evaporator in the air conditioning system. The V-type evaporator is named because its shape is similar to the letter "V". It is a heat exchange component and is usually used in conjunction with a fan. The V-type evaporator is made up of two adjacent evaporators, one of which is close to the air outlet of the fan, so that the angle formed by the two evaporators is toward the air outlet of the fan, and the gas blown out by the fan can pass through the two evaporators, so that the two evaporators can cool the gas blown out by the fan.

[0003] In the prior art, due to installation errors or the fan itself, the flow direction of part of the gas blown out by the fan is parallel to the width direction of one of the evaporators, resulting in a flow blind area, i.e., a low wind speed area, on one of the evaporators. The existence of a low wind speed area on the evaporator means that the air volume flowing through this area is small, so that the evaporator cannot be fully utilized, thereby reducing the heat exchange efficiency of the V-shaped evaporator. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a V-shaped evaporator, which is conducive to improving the heat exchange efficiency of the V-shaped evaporator.

[0005] The utility model also provides an air conditioner with the V-shaped evaporator.

[0006] The V-shaped evaporator according to the first embodiment of the utility model comprises:

[0007] a first evaporator and a second evaporator, wherein the first evaporator is used to be close to an air outlet of a fan, and the second evaporator is connected to the first evaporator in an angled manner so that an angle formed by the first evaporator and the second evaporator is toward the air outlet of the fan;

[0008] A first air guide plate, wherein the length direction of the first air guide plate is parallel to the length direction of the first evaporator, the first air guide plate is arranged between the first evaporator and the second evaporator, the first air guide plate is connected to the first evaporator, and the first air guide plate is arranged at the middle and upper part of the first evaporator in the width direction.

[0009] At least the following beneficial effects:

[0010] The first air guide plate is arranged on the first evaporator, and the first air guide plate is arranged between the first evaporator and the second evaporator, so that part of the gas blown out from the fan with a flow direction parallel to the width direction of the first evaporator can be blown on the first air guide plate, that is, the parallel airflow can be blown to the first air guide plate. The first air guide plate has a guiding function, and the first air guide plate changes the flow direction of the parallel airflow and flows to the first evaporator, so that the first evaporator can cool the parallel airflow after the direction is changed, so that the first evaporator can be fully utilized, which is conducive to improving the heat exchange efficiency of the V-type evaporator. On the other hand, under the action of the first air guide plate, the low wind speed area on the first evaporator disappears, because the first air guide plate can not only change the flow direction of the parallel airflow, but also reduce the wind speed of the low parallel airflow, which reduces the intensity of the Bernoulli principle effect caused by the parallel airflow, that is, the parallel airflow will not produce a low pressure area in the local part of the first evaporator, so that the low wind speed area will not appear in the local part of the first evaporator, and then the air volume flowing through the first evaporator will not be reduced, ensuring that the first evaporator can be fully utilized, which is conducive to improving the heat exchange efficiency of the V-type evaporator.

[0011] The V-shaped evaporator according to the first aspect of the embodiment of the utility model also includes two mounting seats, and the two ends of the first evaporator and the second evaporator in the length direction are respectively connected to the two mounting seats, and the two ends of the first air guide plate in the length direction are respectively connected to the first evaporator through the two mounting seats.

[0012] According to the V-shaped evaporator of the first embodiment of the utility model, mounting parts are provided on both ends of the first air guide plate in the length direction, and the two ends of the first air guide plate in the length direction are respectively connected to the two mounting seats through the mounting parts.

[0013] According to the V-shaped evaporator of the first embodiment of the utility model, the first air guide plate is provided with reinforcing ribs, and the extending direction of the reinforcing ribs is parallel to the length direction of the first air guide plate.

[0014] According to the V-shaped evaporator of the first embodiment of the utility model, the reinforcing rib faces the first evaporator.

[0015] According to the V-shaped evaporator of the first aspect of the utility model embodiment, a second air guide plate is provided on the end of the first air guide plate close to the first evaporator, the length direction of the second air guide plate is parallel to the length direction of the first air guide plate, the second air guide plate faces the second evaporator, and the gap between the second air guide plate and the first evaporator is used for gas to flow through.

[0016] According to the V-shaped evaporator of the first embodiment of the utility model, the length direction of the second air guide plate is parallel to the length direction of the first evaporator.

[0017] According to the V-shaped evaporator of the first embodiment of the utility model, the width of the first air guide plate is 20 to 40 mm.

[0018] According to the V-shaped evaporator of the first embodiment of the utility model, the width of the first air guide plate is 30 mm.

[0019] The air conditioner according to the second embodiment of the utility model includes the V-shaped evaporator.

[0020] At least the following beneficial effects are achieved: the heat exchange efficiency of the air conditioner having the V-shaped evaporator is significantly improved.

[0021] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0035] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0036] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0037] refer to Figure 1 and Figure 2 , Figure 2 In the figure, L is the length direction of the first evaporator 100 , S is the width direction of the first evaporator 100 , and H is the height direction of the first evaporator 100 . Figure 2 The arrow direction in the figure is the portion of gas whose flow direction is parallel to the width direction of the first evaporator 100. For the convenience of explanation, in the present utility model, the portion of gas whose flow direction is parallel to the width direction of the first evaporator 100 is referred to as parallel airflow.

[0038] refer to Figure 1 It is necessary to explain here that the difference between the conventional V-shaped evaporator and the V-shaped evaporator of the embodiment of the utility model is that the conventional V-shaped evaporator does not have the first air guide plate 110, and the conventional V-shaped evaporator also includes the first evaporator 100 and the second evaporator 200. Figure 1 , Figure 1 The shaded area in the figure is the local low wind speed area on the first evaporator 100. Figure 1The direction of the arrow in is the part of the gas whose flow direction is parallel to the width direction of the first evaporator. Because the first evaporator 100 is close to the air outlet of the fan, the velocity of the parallel airflow is faster. According to Bernoulli's principle, a low-pressure area will appear in the vicinity of the parallel airflow with a higher velocity, that is, a low-pressure area will be generated locally in the first evaporator 100. The low-pressure area will greatly reduce the gas flow velocity in or near the area, resulting in a low wind speed area in the first evaporator 100. The presence of a low wind speed area in the first evaporator 100 means that the gas flow velocity in this area is low, which means that the air volume flowing through this area is small, so that the first evaporator 100 cannot be fully utilized, thereby reducing the heat exchange efficiency of the V-type evaporator.

[0039] refer to Figures 3 to 6 The V-shaped evaporator according to the embodiment of the utility model comprises:

[0040] A first evaporator 100 and a second evaporator 200, wherein the first evaporator 100 is used to be close to the air outlet of the fan, and the second evaporator 200 is connected to the first evaporator 100 in an angled manner so that the angle formed by the first evaporator 100 and the second evaporator 200 faces the air outlet of the fan;

[0041] The first air guide plate 110, the length direction of the first air guide plate 110 is parallel to the length direction of the first evaporator 100, the first air guide plate 110 is arranged between the first evaporator 100 and the second evaporator 200, the first air guide plate 110 is connected to the first evaporator 100, and the first air guide plate 110 is arranged in the middle and upper part of the first evaporator 100 in the width direction.

[0042] It is understandable that the first air guide plate 110 is disposed on the first evaporator 100, and the first air guide plate 110 is disposed between the first evaporator 100 and the second evaporator 200, so that part of the gas blown out from the fan and whose flow direction is parallel to the width direction of the first evaporator 100 can be blown onto the first air guide plate 110, that is, the parallel airflow can be blown onto the first air guide plate 110. The first air guide plate 110 has a guiding function. The first air guide plate 110 changes the flow direction of the parallel airflow and flows to the first evaporator 100, so that the first evaporator 100 can cool the parallel airflow after the direction is changed, thereby making the first evaporator 100 fully utilized, which is beneficial to improving the heat exchange efficiency of the V-shaped evaporator. On the other hand, referring to Figure 6Under the action of the first air guide plate 110, the low wind speed area on the first evaporator 100 disappears. This is because the first air guide plate 110 can not only change the flow direction of the parallel airflow, but also reduce the wind speed of the low parallel airflow, which reduces the intensity of the Bernoulli principle effect caused by the parallel airflow, that is, the parallel airflow will not produce a low-pressure area in the local part of the first evaporator 100, so that the low wind speed area will not appear in the local part of the first evaporator 100, and then the air volume flowing through the first evaporator 100 will not be reduced, ensuring that the first evaporator 100 can be fully utilized, which is beneficial to improving the heat exchange efficiency of the V-type evaporator.

[0043] Specifically, the first air guide plate 110 can guide part of the gas whose flow direction is parallel to the width direction of the first evaporator 100 , so that part of the gas can flow toward the first evaporator 100 . Figure 6 The direction of the arrow in is the flow direction of part of the gas parallel to the width direction of the first evaporator.

[0044] refer to Figure 3 The V-shaped evaporator further includes two mounting seats 300, and the two ends of the first evaporator 100 and the second evaporator 200 in the length direction are respectively connected to the two mounting seats 300, and the two ends of the first air guide plate 110 in the length direction are respectively connected to the first evaporator 100 through the two mounting seats 300. It can be understood that the two ends of the first evaporator 100 and the second evaporator 200 in the length direction are respectively connected to the two mounting seats 300, and the length direction of the first evaporator 100 and the length direction of the second evaporator 200 are parallel to each other. In the present utility model, the two mounting seats 300 are used to connect to the corresponding structure of the air conditioner, so that the first evaporator 100 and the second evaporator 200 can be connected to the air conditioner through the two mounting seats 300, and the two mounting seats 300 play a role of support and installation.

[0045] refer to Figure 3 , Figure 4 and Figure 5 , both ends of the first air guide plate 110 in the length direction are provided with mounting parts 111, and both ends of the first air guide plate 110 in the length direction are connected to the two mounting seats 300 through the mounting parts 111. Specifically, threaded holes are provided on the two mounting seats 300, and mounting holes are provided on the two mounting parts 111. The V-shaped evaporator also includes a plurality of connecting parts. The connecting parts are inserted into the mounting holes on the mounting parts 111 and the threaded holes on the mounting seats 300, and the connecting parts are threadedly connected to the inner walls of the threaded holes and pressed against the mounting parts 111, so that the two mounting parts 111 are respectively connected to the two mounting seats 300, and further, the two ends of the first air guide plate 110 in the length direction are respectively connected to the two mounting seats 300 through the mounting parts 111.

[0046] refer to Figure 4 and Figure 7 , the first air guide plate 110 is provided with a reinforcing rib 112, and the extension direction of the reinforcing rib 112 is parallel to the length direction of the first air guide plate 110. It can be understood that the reinforcing rib 112 can improve the structural strength of the first air guide plate 110 and prevent the first air guide plate 110 from shaking. As an embodiment of the utility model, the reinforcing rib 112 faces the first evaporator 100. In the utility model, the reinforcing rib 112 is convex, and the reinforcing rib 112 facing the first evaporator 100 can also guide the parallel airflow after the direction is changed, and can hinder the parallel airflow after the direction is changed from flowing toward the fan to a certain extent, so that the parallel airflow after the direction is changed can flow to the first evaporator 100 as much as possible.

[0047] refer to Figure 4 and Figure 7 A second air guide plate 113 is disposed on one end of the first air guide plate 110 close to the first evaporator 100, the length direction of the second air guide plate 113 is parallel to the length direction of the first air guide plate 110, the length direction of the second air guide plate 113 is parallel to the length direction of the first evaporator 100, the second air guide plate 113 faces the second evaporator 200, and the gap between the second air guide plate 113 and the first evaporator 100 is used for gas to flow through. As an embodiment of the utility model, the two sides of the second air guide plate 113 opposite to the first evaporator 100 are parallel to each other. It can be understood that the gap between the end of the first air guide plate 110 close to the first evaporator 100 and the first evaporator 100 is used for gas to flow through, and the second air guide plate 113 is arranged on the end of the first air guide plate 110 close to the first evaporator 100, and the gap between the second air guide plate 113 and the first evaporator 100 is used for gas to flow through. The second air guide plate 113 can guide the gas flowing between the first air guide plate 110 and the first evaporator 100 to prevent the gas blown out from between the second air guide plate 113 and the first evaporator 100 from affecting the flow direction of gas in other areas.

[0048] As an embodiment of the utility model, the width of the first air guide plate 110 is 20 to 40 mm. Preferably, the width of the first air guide plate 110 is 30 mm. When the width of the first air guide plate 110 is 30 mm, the first air guide plate 110 can not only prevent the first evaporator 100 from having a low wind speed area, but also prevent the first air guide plate 110 from causing a large wind resistance to the gas blown out by the fan.

[0049] As an embodiment of the utility model, the angle between the first air guide plate 110 and the horizontal plane is -10° to 10°. When it is necessary to explain, when the angle between the first guide plate and the horizontal plane is a negative number, it means that the first guide plate is in a downward swing toward one end of the fan, and when the angle between the first guide plate and the horizontal plane is a positive number, it means that the first guide plate is in an upward swing toward one end of the fan.

[0050] In the embodiment of the present utility model, reference Figure 5 and Figure 6 In the up-down direction, the first air guide plate 110 is located in the middle and upper part of the first evaporator 100 , that is, the first air guide plate 110 is arranged in the middle and upper part of the first evaporator 100 in the width direction.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
