Description

Technical Field

[0001] The present invention relates to the field of heat exchange, and in particular to a heat exchanger assembly and an air conditioner having the same. Background Art

[0002] The heat exchanger area is a key factor affecting the heat transfer performance of the air conditioner. The larger the heat exchanger area, the easier it is to achieve a good heat transfer effect. Achieving a larger heat exchanger area within a limited space is one of the key points in designing an air conditioner.

[0003] The prior art discloses a cabinet air conditioner capable of achieving reversible up and down air outlet, which adopts a V-shaped heat exchanger, and its upper air port can be used as both an air inlet and an air outlet. When the upper air port is an air inlet, air flows in from the upper air port, passes through the V-shaped heat exchanger, and enters the air duct; when the upper air port is an air outlet, air flows out from the air duct, passes through the V-shaped heat exchanger, and is discharged from the upper air port.

[0004] Its V-shaped heat exchanger uses a double-row heat exchanger with a large heat exchange area, but there are the following problems:

[0005] When air is discharged from the upwind vent, the pressure difference between the upper and leeward sides of the heat exchanger is large, while the pressure difference between the lower and leeward sides of the heat exchanger is small, resulting in more airflow passing through the upper part of the heat exchanger than the lower part, causing uneven air intake in the heat exchanger, which in turn affects the heat exchange capacity.

[0006] When air is entering from the upwind vent, there is also the problem of uneven air intake into the heat exchanger: when air is entering from the upwind vent, the pressure difference between the upper and leeward sides of the heat exchanger is small, while the pressure difference between the lower and leeward sides of the heat exchanger is large, resulting in more airflow passing through the lower part of the heat exchanger than the upper part, resulting in uneven air intake into the heat exchanger, affecting the heat exchange capacity.

[0007] It can be seen that the heat exchanger in the prior art has the following defects:

[0008] It is difficult to achieve large-area heat exchange in a limited space.

[0009] The air inlet to the heat exchanger is uneven, resulting in poor heat exchange effect. Summary of the invention

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] The heat exchanger assembly of this embodiment, such as Figures 1 to 5 As shown, it includes: a first heat exchanger 1; a second heat exchanger 2, wherein the first end of the first heat exchanger 1 is connected to the first end of the second heat exchanger 2; a third heat exchanger 3, wherein the third heat exchanger 3 is connected to the second end of the first heat exchanger 1 and / or the second end of the second heat exchanger 2; wherein the first heat exchanger 1, the second heat exchanger 2 and the third heat exchanger 3 are all single-row heat exchangers. The heat exchanger assembly of this embodiment is improved on the basis of the existing V-shaped heat exchanger assembly composed of two heat exchangers, and is provided with a first heat exchanger 1, a second heat exchanger 2 and a third heat exchanger 3, thereby increasing the contact area between the heat exchanger in the heat exchanger assembly and the airflow. At the same time, the heat exchanger is replaced from the original double-row heat exchanger to a single-row heat exchanger, which effectively reduces the wind resistance of the airflow passing through the heat exchanger. The above arrangement improves the uniformity of the air intake of the heat exchanger assembly, reduces the pressure difference between the windward side and the leeward side of the heat exchanger in the heat exchanger assembly, realizes a large heat exchange area of ​​the heat exchanger in a limited space, and solves the problem of poor heat exchange effect of the heat exchanger in the prior art.

[0036] It should be noted that in order to improve the heat exchange performance of the heat exchanger in the prior art, the heat exchange tubes of the heat exchanger are often arranged in double rows. Although this method can improve the heat exchange effect, the airflow passing through the radiator is subject to greater resistance, which will cause poor ventilation of the radiator. The radiator in this embodiment arranges the heat exchange tubes in a single row, so that the airflow through the heat exchanger is smoother, thereby improving the performance of the radiator. The single-row heat exchanger in this embodiment means that the single-row heat exchanger is only provided with one row of heat exchange tubes.

[0037] like Figure 1 , Figure 2 As shown, in the heat exchanger assembly of this embodiment, one end of the third heat exchanger 3 is connected to the second end of the first heat exchanger 1 , and the other end of the third heat exchanger 3 is connected to the second end of the second heat exchanger 2 .

[0038] By adopting the above arrangement, the heat exchanger assembly is formed into a triangular structure, making the heat exchange assembly more solid. In addition, when the heat exchanger is exchanging heat, the airflow passes through the first heat exchanger 1 and the second heat exchanger 2, and then passes through the third heat exchanger 3, thereby performing secondary heat exchange on the airflow, thereby increasing the heat exchange efficiency of the heat exchange assembly.

[0039] In order to increase the performance of the heat exchanger assembly, in the heat exchanger assembly of this embodiment, the first heat exchanger 1, the second heat exchanger 2 and the third heat exchanger 3 constitute a heat exchange body, and there are multiple heat exchange bodies, which are arranged in sequence along a preset direction.

[0040] In order to increase the heat transfer efficiency of the heat exchanger components, such as Figure 2 As shown, in this embodiment, the lengths of the first heat exchanger 1 and the second heat exchanger 2 are both L1, and the length of the third heat exchanger 3 is L2; ​​wherein,

[0041] It should be noted that in this embodiment, the extension direction of the heat exchange tubes arranged inside each heat exchanger in the heat exchanger assembly is consistent, and the lengths L1 and L2 of the heat exchangers here refer to the lengths of the heat exchangers extending along the direction in which the heat exchange tubes arranged inside them are arranged.

[0042] In the heat exchanger assembly of this embodiment, the angle between the first heat exchanger 1 and the second heat exchanger 2 is α, wherein 14°<α≤120°. Through the above arrangement, the heat exchange efficiency of the heat exchanger assembly can be further increased.

[0043] like Figure 3 , Figure 4 As shown, in the heat exchanger assembly of this embodiment, the third heat exchanger 3 is located at an end of the second heat exchanger 2 away from the first heat exchanger 1 , and a first end of the third heat exchanger 3 is connected to the second heat exchanger 2 .

[0044] In the heat exchanger assembly of this embodiment, Figure 3 , Figure 4 As shown, the third heat exchanger 3 is located at one end of the second heat exchanger 2 away from the first heat exchanger 1, and the first end of the third heat exchanger 3 is connected to the second heat exchanger 2. This structure further increases the lateral distribution area of ​​the heat exchanger assembly, so that the effective heat exchange area of ​​the heat exchanger assembly is increased, thereby increasing the heat exchange performance of the heat exchanger assembly.

[0045] In the heat exchanger assembly of this embodiment, Figure 3 , Figure 4 As shown, the heat exchanger assembly also includes: a fourth heat exchanger 4, which is located at an end of the third heat exchanger 3 away from the second heat exchanger 2, and the first end of the fourth heat exchanger 4 is connected to the second end of the third heat exchanger 3; wherein the fourth heat exchanger 4 is a single-row heat exchanger.

[0046] like Figure 3 , Figure 4 As shown, in this embodiment, the heat exchanger assembly further includes: a fourth heat exchanger 4, which is a single-row heat exchanger, and is located at an end of the third heat exchanger 3 away from the second heat exchanger 2, and a first end of the fourth heat exchanger 4 is connected to a second end of the third heat exchanger 3. Through the above arrangement, the heat exchanger assembly is formed into a more stable structure, and the contact area between the heat exchanger assembly and the airflow is increased, thereby increasing the heat exchange performance of the heat exchanger assembly.

[0047] like Figure 3 , Figure 4 As shown, in the heat exchanger assembly of this embodiment, the third heat exchanger 3 is arranged in parallel with the first heat exchanger 1; and / or the fourth heat exchanger 4 is arranged in parallel with the second heat exchanger 2.

[0048] By arranging the third heat exchanger 3 in parallel with the first heat exchanger 1 and the fourth heat exchanger 4 in parallel with the second heat exchanger 2, the contact between the heat exchanger assembly and the airflow is made more uniform, thereby increasing the heat exchange performance of the heat exchanger assembly.

[0049] In the heat exchanger assembly of this embodiment, the heat exchanger assembly also includes: a fifth heat exchanger 5, one end of the fifth heat exchanger 5 is connected to the first heat exchanger 1, and the other end of the fifth heat exchanger 5 is connected to the fourth heat exchanger 4; wherein the fifth heat exchanger 5 is a single-row heat exchanger.

[0050] In order to further increase the heat exchange efficiency of the heat exchanger assembly, in the present embodiment, the heat exchanger assembly further includes: a fifth heat exchanger 5, which is a single-row heat exchanger, one end of the fifth heat exchanger 5 is connected to the first heat exchanger 1, and the other end of the fifth heat exchanger 5 is connected to the fourth heat exchanger 4. In this way, after the airflow passes through the structure composed of the first heat exchanger 1, the second heat exchanger 2, the third heat exchanger 3 and the fourth heat exchanger 4, it passes through the fifth heat exchanger 5 for secondary heat exchange, thereby increasing the heat exchange efficiency of the heat exchanger.

[0051] In the heat exchanger assembly of this embodiment, the first heat exchanger 1, the second heat exchanger 2, the third heat exchanger 3 and the fourth heat exchanger 4 constitute a heat exchange body. There are multiple heat exchange bodies, and the multiple heat exchange bodies are arranged in sequence along a preset direction, thereby increasing the heat exchange capacity of the heat exchanger assembly.

[0052] like Figure 3 , Figure 4 As shown, in the heat exchanger assembly of this embodiment, the length of the first heat exchanger 1 is equal to the length of the fourth heat exchanger 4 ; the length of the second heat exchanger 2 is equal to the length of the third heat exchanger 3 .

[0053] It should be noted that in this embodiment, the extension direction of the heat exchange tubes arranged inside each heat exchanger in the heat exchanger assembly is consistent, and the length of the heat exchanger here refers to the length of the heat exchanger extending along the direction in which the heat exchange tubes arranged inside it are arranged.

[0054] The above arrangement makes the structure of the heat exchanger assembly symmetrical, thereby making the contact between the heat exchanger assembly and the airflow more uniform, thereby increasing the heat exchange efficiency of the heat exchanger assembly.

[0055] In order to further improve the performance of the heat exchanger assembly in this embodiment, the lengths of the first heat exchanger 1 and the fourth heat exchanger 4 are both a, and the lengths of the second heat exchanger 2 and the third heat exchanger 3 are both b; wherein 5:2≤a:b≤1:1.

[0056] In the heat exchanger assembly of this embodiment, the angle between the first heat exchanger 1 and the second heat exchanger 2 is α, 15°≤α≤35°; and / or the angle between the third heat exchanger 3 and the fourth heat exchanger 4 is β, 15°≤β≤35°; and / or the angle between the second heat exchanger 2 and the third heat exchanger 3 is γ, 15°≤γ≤35°.

[0057] In the air conditioner of this embodiment, the air conditioner includes a heat exchanger assembly, and the heat exchanger assembly is the heat exchanger assembly mentioned above.

[0058] It should be noted that the heat exchanger assembly of this embodiment is used in a cabinet air conditioner with reversible up and down air outlet. The reversible up and down air conditioner using this heat exchanger assembly can increase the heat exchange area of ​​the heat exchanger within a limited space, improve the uneven air intake of the heat exchanger, and improve the heat exchange efficiency.

[0059] The specific structure of the heat exchanger assembly of the air conditioner is as follows:

[0060] like Figure 5As shown, the air conditioner of this embodiment includes a housing 10, an upper air outlet 20, a heat exchanger assembly 30 and a water receiving tray 40. The heat exchanger assembly 30 is composed of a first heat exchanger 1, a second heat exchanger 2, a third heat exchanger 3 and a fourth heat exchanger 4. The first heat exchanger 1 and the third heat exchanger 3 have the same length, which is a, and the second heat exchanger 2 and the fourth heat exchanger 4 have the same length, which is b; the first heat exchanger 1 and the second heat exchanger 2 are arranged at an angle α, and the first end face of the first heat exchanger 1 is connected to the first end face of the second heat exchanger 2; the second heat exchanger 2 and the third heat exchanger 3 are arranged at an angle β, and the second end of the second heat exchanger 2 is connected to the first end face of the third heat exchanger 3; the third heat exchanger 3 and the fourth heat exchanger 4 are arranged at an angle γ, and the second end face of the third heat exchanger 3 is connected to the first end face of the fourth heat exchanger 4, and the second end face of the fourth heat exchanger 4 is away from the second end face of the third heat exchanger 3. The range of values ​​of the relevant dimensions is: 5:2≤a:b≤1:1, 15°≤α≤35°, 15°≤β≤35°, 15°≤γ≤35°. In this embodiment, a:b=5:4, α=25°, β=25°, γ=25°. Changing the double-row heat exchanger to a single-row heat exchanger can effectively reduce the wind resistance of the airflow through the heat exchanger. At the same time, in order to achieve a large heat exchange area in a limited space, a W-shaped heat exchanger layout is adopted. Compared with the existing double-row V-shaped heat exchanger, the heat exchanger has a considerable heat exchange area, small wind resistance, large effective heat exchange area, and more uniform heat exchange.

[0061] From the perspective of improving the pressure difference between the windward and leeward sides of the heat exchanger, another embodiment of the heat exchanger assembly is proposed, such as Figure 1 As shown, based on the V-shaped single-row heat exchanger, a horizontal row of heat exchangers is added on the top to form a closed inverted triangle with the V-shape. The heat exchanger assembly 30 consists of a first heat exchanger 1, a second heat exchanger 2, and a third heat exchanger 3. The first heat exchanger 1 and the second heat exchanger 2 have the same length, which is a, and the third heat exchanger 3 has a length b; the first heat exchanger 1 and the second heat exchanger 2 are set at an angle α, and the first end face of the first heat exchanger 1 is connected to the first end face of the second heat exchanger 2; the first end face of the third heat exchanger 3 is connected to the second end face of the first heat exchanger 1, and the second end face of the third heat exchanger 3 is connected to the second end face of the second heat exchanger 2. Among them, the relevant dimensions can take a range of values: 14°<α≤120°, in this embodiment, a:b=2:1, α=14.5°. The heat exchanger with this layout can reduce the static pressure inside the triangular heat exchanger assembly, that is, increase the pressure difference between the windward and leeward sides of the heat exchanger, make it easier for airflow to enter the heat exchanger, and improve the heat exchange efficiency.

[0062] Figure 4It is another embodiment of the radiator assembly of the air conditioner. This embodiment can reduce wind resistance and increase the pressure difference between the windward and leeward sides of the heat exchanger. On the basis of a single-row W-shaped heat exchanger, a horizontal row of heat exchangers is added on the top to form a closed layout with the W-shaped heat exchanger, which has a larger heat exchange area.

[0063] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0064] The heat exchanger assembly of this embodiment includes: a first heat exchanger 1; a second heat exchanger 2, wherein the first end of the first heat exchanger 1 is connected to the first end of the second heat exchanger 2; and a third heat exchanger 3, wherein the third heat exchanger 3 is connected to the second end of the first heat exchanger 1 and / or the second end of the second heat exchanger 2; wherein the first heat exchanger 1, the second heat exchanger 2 and the third heat exchanger 3 are all single-row heat exchangers. The heat exchanger assembly of this embodiment is improved on the basis of the existing V-shaped heat exchanger assembly composed of two heat exchangers, and is provided with the first heat exchanger 1, the second heat exchanger 2 and the third heat exchanger 3, thereby increasing the contact area between the heat exchanger in the heat exchanger assembly and the airflow. At the same time, the heat exchanger is replaced from the original double-row heat exchanger to the single-row heat exchanger, which effectively reduces the wind resistance of the airflow passing through the heat exchanger. The above arrangement improves the uniformity of the air intake of the heat exchanger assembly, reduces the pressure difference between the windward side and the leeward side of the heat exchanger in the heat exchanger assembly, realizes a large heat exchange area of ​​the heat exchanger in a limited space, and solves the problem of poor heat exchange effect of the heat exchanger in the prior art.

For those skilled in the art, the present invention may have various modifications and variations.
