[0004] To solve the above problem, although the related technology provides the condenser with three rows of heat exchange copper pipes, the flow path setting of the three rows of heat exchange copper pipes is simple, which leads to the failure to fully realize the heat exchange effect of the outdoor heat exchanger. SUMMARY

[0005] The technical problem solved by the utility model is that although the related technology provides the condenser with three rows of heat exchange copper pipes, the flow path setting of the three rows of heat exchange copper pipes is simple, which leads to the failure to fully realize the heat exchange effect of the outdoor heat exchanger.

[0006] To solve the above problem, the utility model provides a condenser of air conditioner, which comprises a mounting main body, a plurality of U tubes and a plurality of elbows, and the plurality of U tubes and the plurality of elbows are mounted on the mounting main body; the mounting main body is provided with a windward side and an air outlet side arranged oppositely; the plurality of elbows are connected with the plurality of U tubes respectively to form a plurality of refrigerant flow paths; any refrigerant flow path comprises a first row of pipe groups arranged on the windward side, a second row of pipe groups arranged on the air outlet side and a third row of pipe groups arranged between the windward side and the air outlet side; wherein the refrigerant in the refrigerant inlet header is collected by the first row of pipe groups and output to the refrigerant outlet header through the second row of pipe groups and the third row of pipe groups; the second row of pipe groups are provided with a refrigerant inlet port communicated with the refrigerant inlet header; the first row of pipe groups are provided with a refrigerant outlet port communicated with the refrigerant outlet header; wherein the number of the refrigerant inlet ports is more than the number of the refrigerant outlet ports.

[0007] Compared with the prior art, the technical effects achieved by adopting the technical scheme are as follows: specifically, by arranging the condenser with three rows of heat exchange pipes formed by the first row of pipe groups, the second row of pipe groups and the third row of pipe groups, the height of the condenser is effectively reduced, so that a single outdoor fan can cover the condenser, and the heat exchange efficiency of the condenser is improved; in addition, compared with the related technical scheme in which the number of the refrigerant inlet ports is the same as the number of the refrigerant outlet ports, the number of the refrigerant inlet ports is increased in the present technical scheme, thereby increasing the flow of the refrigerant input from the refrigerant inlet header to the plurality of refrigerant flow paths in a short time, to a certain extent, the flow rate of the refrigerant participating in the refrigeration cycle of the air conditioner is improved, and the heat exchange efficiency of the air conditioner is improved.

[0008] In one example of the present application, in any refrigerant flow path, the setting height of the refrigerant inlet on the installation body is higher than the setting height of the refrigerant outlet on the installation body.

Specifically, when the two are too close to each other, the temperature of the refrigerant output through the refrigerant outlet is likely to rise, thereby affecting the supercooling degree of the refrigerant. In addition, since the setting height of the refrigerant inlet is higher than the setting height of the refrigerant outlet, the liquid refrigerant is easily introduced into the refrigerant outlet header under the action of its own gravity.

[0011] Compared with the prior art, the technical effects achieved by adopting the technical scheme are as follows: the wind speed at the top air outlet position or near the top air outlet position is larger than that at other positions, which means that the heat exchange efficiency between the first refrigerant flow path arranged at the top air outlet position and the surrounding environment is higher than that between the refrigerant flow path not arranged at the top air outlet position and the surrounding environment. Therefore, by adjusting the number of U tubes constituting the first refrigerant flow path and the second refrigerant flow path respectively, the temperature difference of each refrigerant flow path input to the refrigerant outlet header is maintained at a small difference, thereby reducing heat exchange loss.

[0012] In one example of the present application, the number of U tubes constituting the first tube group is 2-4; and / or the number of U tubes constituting the second tube group is 2-4; and / or the number of U tubes constituting the third tube group is 2-4.

[0013] Compared with the prior art, the technical effects achieved by adopting the technical scheme are as follows: by reasonably setting the number of U tubes of the first tube group, the second tube group and the third tube group, the heat exchange efficiency of the condenser is ensured.

[0016] In one example of the utility model, the number of refrigerant flow paths is 9-11; and / or the number of U tubes constituting the refrigerant flow paths is 72-84.

[0017] Compared with the prior art, the technical scheme has the technical effect of further ensuring the heat exchange efficiency of the condenser.

[0018] In one example of the utility model, any refrigerant flow path comprises a first refrigerant branch, a three-way pipe, a second refrigerant branch and a collecting branch connected with each other; one end of the first refrigerant branch and one end of the second refrigerant branch are connected to the refrigerant inlet header through the intake branch pipe group; the other end of the first refrigerant branch is communicated with the first end of the three-way pipe, and the other end of the second refrigerant branch is communicated with the second end of the three-way pipe; the third end of the three-way pipe is communicated with one end of the collecting branch, and the other end of the collecting branch is communicated with the refrigerant outlet header through the liquid outlet branch pipe.

[0019] In one example of the utility model, the first refrigerant branch comprises a first upper branch and a second upper branch communicated at the first end; the first upper branch and the second upper branch are connected between the first end and the first intake branch pipe of the intake branch pipe group; the second refrigerant branch comprises a first lower branch and a second lower branch communicated at the second end; the first lower branch and the second lower branch are connected between the second end and the second intake branch pipe of the intake branch pipe group; wherein the first upper branch and the first lower branch constitute the second pipe group; the second upper branch and the second lower branch constitute the third pipe group; and the collecting branch constitutes the first pipe group.

[0020] In one example of the utility model, any one of the first refrigerant branch, the second refrigerant branch and the collecting branch is composed of at least two U tubes.

[0021] Compared with the prior art, the technical scheme has the technical effect of further improving the heat exchange efficiency of the condenser.

[0022] On the other hand, the utility model also provides a kind of air conditioner, comprising: outdoor unit, outdoor unit for example comprising the condenser in any of the above examples.

[0023] Compared with the prior art, the technical scheme has the technical effect of further ensuring the heat exchange efficiency of the condenser.

[0025] (1) by setting the condenser formed by the first row pipe group, the second row pipe group and the third row pipe group, the height of the condenser is effectively reduced, so that a single outdoor fan can cover the condenser, and the heat exchange efficiency of the condenser is improved;

[0026] (2) The wind speed at the top air outlet position is larger than that at other positions, which means that the heat exchange efficiency between the first refrigerant flow path arranged at the top air outlet position and the surrounding pipe environment is higher than that between the refrigerant flow path not arranged at the top air outlet position and the surrounding pipe environment. Therefore, by adjusting the number of U-shaped pipes respectively constituting the first refrigerant flow path and the second refrigerant flow path, the temperature difference of each refrigerant flow path input to the refrigerant outlet header is maintained at a small difference, thereby reducing heat exchange loss;

[0033] ​In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0034] Referring to Figure 1 , which is a structural schematic view of a condenser 100 of an air conditioner provided by the present application. In combination with Figure 2 , specifically, the condenser 100 comprises a mounting body, a plurality of U-tubes 107 and a plurality of elbows 108, the plurality of U-tubes 107 and the plurality of elbows 108 are all mounted on the mounting body; the mounting body is provided with a windward side 101 and an air outlet side 102 arranged oppositely; the plurality of elbows 108 are respectively connected with the plurality of U-tubes 107 to form a plurality of refrigerant flow paths; any refrigerant flow path comprises a first row pipe group 104 arranged on the windward side 101, a second row pipe group 105 located on the air outlet side 102, and a third row pipe group 106 located between the windward side 101 and the air outlet side 102; wherein the refrigerant in the refrigerant inlet header is respectively collected by the first row pipe group 104 and output to the refrigerant outlet header through the second row pipe group 105 and the third row pipe group 106.

[0035] Preferably, the second row pipe group 105 is provided with a refrigerant inlet port communicated with the refrigerant inlet header; the first row pipe group 104 is provided with a refrigerant outlet port communicated with the refrigerant outlet header; wherein the number of the refrigerant inlet ports is more than the number of the refrigerant outlet ports. Compared with the related technical solution in which the number of the refrigerant inlet ports is set to be the same as the number of the refrigerant outlet ports, the number of the refrigerant inlet ports is increased in the present technical solution, thereby increasing the flow of the refrigerant input from the refrigerant inlet header to the plurality of refrigerant flow paths in a short time, to a certain extent, the flow rate of the refrigerant participating in the refrigeration cycle of the air conditioner is improved, thereby improving the heat exchange efficiency of the air conditioner.

[0036] Preferably, in any refrigerant flow path, the setting height of the refrigerant inlet port on the mounting body is higher than the setting height of the refrigerant outlet port on the mounting body.

[0037] In combination with the actual installation situation of the condenser 100 in the outdoor unit, by setting the setting height of the refrigerant inlet port to be higher than the setting height of the refrigerant outlet port, the refrigerant outlet port and the refrigerant inlet port are presented to be set in a staggered manner on the mounting body, avoiding that they are too close to each other, resulting in heat transfer. Specifically, when they are too close to each other, the temperature of the refrigerant output through the refrigerant outlet port is easily increased, thereby affecting the supercooling degree of the refrigerant. In addition, since the setting height of the refrigerant inlet port is higher than the setting height of the refrigerant outlet port, the liquid refrigerant is easily introduced from the refrigerant outlet port to the refrigerant outlet header under the action of its own gravity.

[0039] The wind speed at the top air outlet position 103 is greater than that at other positions, which means that the heat exchange efficiency between the first refrigerant flow path arranged at the top air outlet position 103 and the surrounding environment outside the tube is higher than that between the refrigerant flow path not arranged at the top air outlet position 103 and the surrounding environment outside the tube. Therefore, by adjusting the number of U-tubes 107 constituting the first refrigerant flow path and the second refrigerant flow path respectively, the temperature difference of each refrigerant flow path input to the refrigerant outlet header is maintained at a small difference, thereby reducing heat exchange loss.

[0040] Further, the heat exchange efficiency between the refrigerant flow path and the surrounding environment outside the tube also relates to the number of U-tubes 107 arranged on the windward side 101. The more U-tubes 107 arranged on the windward side 101, the higher the heat exchange efficiency. Therefore, in combination with the above, in order to reduce the influence of the surrounding environment outside the tube on the first refrigerant flow path and the second refrigerant flow path, resulting in a large difference in heat exchange efficiency, by reasonably adjusting the number of U-tubes 107 of the first refrigerant flow path and the second refrigerant flow path on the windward side 101, the difference in heat exchange efficiency between the first refrigerant flow path and the second refrigerant flow path is reduced, thereby effectively maintaining the heat exchange efficiency between each refrigerant flow path balanced, thereby improving the overall heat exchange efficiency of the air conditioner.
