Embodiment 1

[0017] Embodiment one, such as Figure 1-Figure 3 As shown, the condenser of the present invention includes a front row condenser 1 and a rear row condenser 2, and the height h2 of the rear row condenser 2 is half of the height h1 of the front row condenser 1, and is arranged on the upper half of the rear row, refrigerating The agent inlet is located in the middle of the back row condenser 2, the outlet is located at the lower end of the front row, and the front and rear rows are connected by a pipeline 3.

[0018] from figure 2 It can be seen that the front row is on the windward side, and the outdoor air is blown in from the outside of the front row, and first exchanges heat with the front row condenser. Since only a part of the rear row condenser is reserved, when the air passes through the rear row condenser, the airflow will flow again. The resistance is reduced, and greater air can be obtained under the same fan operation, which improves the heat exchange efficiency. A...

Embodiment 2

[0019] Embodiment two, such as Figure 4 As shown, the difference from Embodiment 1 is that the rear row condenser 2 of this embodiment is located in the lower half of the rear row, and this design can also achieve the effects of reducing wind resistance and increasing heat exchange capacity.

[0020] Of course, the position of the rear condensers can also be arranged up and down, which is not shown in the figure, that is, the rear condensers are arranged at the upper and lower ends, and the height of each part is 1 / 4 of the height of the front condensers. The entrance of the car is divided into two ways, which are respectively located at the upper end of the upper and lower parts, and the exit is located at the lower end of the front row. Similarly, since only a part of the rear condenser is reserved, when the air passes through the rear condenser, the flow resistance of the air flow is reduced, and the heat exchange efficiency is improved.

Embodiment 3

[0021] Embodiment three, will Figure 1-3 The shown condenser is used in an air conditioner. The condenser includes a front row condenser 1 and a rear row condenser 2. The height of the rear row condenser 2 is half the height of the front row condenser 1 and is located in the upper half of the rear row , the refrigerant inlet is located in the middle of the rear row of condensers 2, the outlet is located at the lower end of the front row, and the front and rear rows are connected by a pipeline 3. In this way, the entire condenser becomes partly single-row design and partly double-row design, which effectively reduces the wind resistance caused by the rear condenser and improves the heat exchange efficiency.

Abstract

The invention relates to a high-efficient condenser and an air conditioner with the condenser, belonging to the technical field of air conditioner. The condenser comprises a front row condenser and a back row condenser, wherein the height of the back row condenser is (1 / 6)-(3 / 4) of the height of the front row condenser. The invention reduces the number of the back row condenser that has reduced heat exchange efficiency as much as possible, thus, part of the entire condenser has single-row design, so as to increase heat exchange air speed, further reinforce the heat exchange at the supercooling zone of the condenser, and improve heat exchange efficiency. Meanwhile, the weight of the inventive condenser is much smaller than the weight of the existing condenser, so as to remarkably reduce the production cost.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a condenser in an air conditioner. Background technique [0002] The outdoor heat exchanger of the traditional split air conditioner generally adopts a double-row design, and the front and rear rows are about the same size. Among them, the heat exchange of the rear row only accounts for 10% to 25% of the total heat exchange, and the heat exchange of the front row accounts for 75% to 90% of the total heat exchange. There is a huge difference in the heat exchange of the front and rear rows. , leading to a low overall heat transfer capacity of the condenser. The reason is that during the heat exchange process, when the outside air flows through the front row and exchanges heat with the fins, the temperature in the condenser will rise, and when such airflow enters the rear row to exchange heat with the copper tubes and fins, The temperature difference between t...
