Description

Outdoor unit, heat pump water heater and air conditioner

Technical Field

The utility model relates to the technical field of electrical apparatus, especially, relate to an outdoor unit, heat pump water heater and air conditioner.

Background

Each of the heat pump water heater and the air conditioner includes an outdoor unit, as shown in fig. 1 and 2, including a casing 1', a compressor 2', a heat exchanger 3', and a fan 4'. Typically, the housing 1' generally includes a first chamber 61' and a second chamber 62'. The heat exchanger 3 'is embedded in the housing 1' and forms a side wall of the first chamber 61', the fan 4' is arranged in the first chamber 61', when the fan 4' rotates, negative pressure is generated in the first chamber 61', and external low-temperature air enters the first chamber 61' through the heat exchanger 3 'and is discharged after passing through the fan 4'. The external low-temperature air continuously passes through the heat exchanger 3 'to exchange heat with the heat exchanger 3', and the fan 4 'is the power for the low-temperature air to continuously flow through the heat exchanger 3'. The compressor 2' is arranged in the second chamber 62', the side of the heat exchanger 3' close to the second chamber 62' is provided with an end plate 8', a partition plate 7' is also arranged in the shell 1', and the partition plate 7' and the end plate 8' jointly realize the separation of the first chamber 61' and the second chamber 62'.

In some cases, for example, a heat pump water heater, because the size of the main control board is large, a large electronic control box 9 'needs to be configured and integrated in the casing 1' of the outdoor unit. In the prior art, as shown in fig. 1, the electronic control box 9 'is disposed above the partition 7', and in order to facilitate heat dissipation of the electronic control box 9', the heat dissipation portion of the electronic control box 9' is located in the first chamber 61', and the rest is located in the second chamber 62'. At this time, as shown in fig. 2, a gap 5' is formed between the end plate 8' of the heat exchanger 3' and the outer wall of the electrical control box 9' above the partition 7 '. When the fan 4 'is operated and generates suction force, a part of air enters the first chamber 61' from the second chamber 62 'through the gap 5', and under the condition that the power of the fan 4 'is constant, the existence of the gap 5' can reduce the total amount of low-temperature air flowing through the heat exchanger 3', thereby affecting the heat exchange efficiency of the heat exchanger 3'.

Since the partition plate 7' is generally made of a sheet metal, if the partition plate is directly extended upward to close the gap 5', the manufacturing blank of the partition plate 7' is greatly increased, and the cost is increased; further, since the portion to be extended is elongated, the manufacturing accuracy is difficult to ensure.

Therefore, an outdoor unit, a heat pump water heater and an air conditioner are needed to solve the above technical problems.

The embodiment provides an outdoor unit, a heat pump water heater and an air conditioner. The air conditioner comprises the outdoor unit. The heat pump water heater also comprises the outdoor unit. In the present embodiment, the outdoor unit is used as an example of a heat pump water heater.

As shown in fig. 3-5. The outdoor unit includes a casing 1, and the casing 1 has a rectangular parallelepiped structure and includes an upper casing 12, a lower casing 16, a left casing 14, a right casing 15, a front casing 13, and a rear casing 11. Preferably, the housing 1 is machined from sheet metal. In other embodiments, the housing 1 may be made of plastic. Further, the outdoor unit further includes a heat exchanger 2, and the heat exchanger 2 is embedded in the casing 1. Specifically, the heat exchanger 2 may be an evaporator, and the heat exchanger 2 is generally in a plate-like structure. In the present embodiment, the heat exchanger 2 is substantially L-shaped, and a part of the L-shape is embedded in the rear shell 11 of the housing 1, and a part of the L-shape is located inside the housing 1 and is disposed opposite to the left shell 14. The heat exchanger 2 has a multi-fin structure (not shown), so that the outside of the casing 1 is communicated with the inside of the casing 1, the outside air can pass through the heat exchanger 2 from the outside to enter the inside of the casing 1, and the outside air exchanges heat with the heat exchanger 2 in the process of passing through the heat exchanger 2 (mainly, the outside low-temperature air takes away heat of the heat exchanger 2).

Specifically, as shown in fig. 5, the rear case 11 includes a side portion 112 and a top portion 111, and the heat exchanger 2 is embedded in the rear case 11 below the top portion 111 on the side of the side portion 112. Preferably, as shown in fig. 5, a plurality of through holes are formed in the left case 14 so that the external low-temperature air can enter the inside of the case 1 through the through holes and exchange heat through the left portion of the heat exchanger 2.

As shown in fig. 4, the heat exchanger 2 has a certain thickness, so the heat exchanger 2 further includes an end plate 21 vertically disposed, the end plate 21 is located inside the outer shell 1 and is perpendicular to the rear shell 11, and the end plate 21 is used for connecting the heat exchanger 2 with the side portion 112 of the rear shell 11.

Further, as shown in fig. 4 and 5, the outdoor unit further includes a partition plate 3, a blower 6, an electric control box 5, and a compressor 7. The partition plate 3 is arranged in the shell 1, the partition plate 3 and the end plate 21 are butted along the front and back direction, and the partition plate 3 and the end plate 21 divide the shell 1 into a first chamber 41 and a second chamber 42. The heat exchanger 2 is located in the first chamber 41, and a part of the heat exchanger 2 constitutes a side wall of the rear side of the first chamber 41. The fan 6 is disposed in the first chamber 41, and the compressor 7 is disposed in the second chamber 42. An air opening 131 is provided at a position of the front case 13 opposite to the first chamber 41, and the air opening 131 is used for exhausting air. The electronic control box 5 is arranged above the partition plate 3, and is partially positioned in the first chamber 41 and partially positioned in the second chamber 42.

When the outdoor unit is operated, the heat exchanger 2 generates heat and needs to be cooled. At this time, the fan 6 rotates, the rotation of the fan 6 causes a negative pressure to be formed at a part of one side of the fan facing the heat exchanger 2 (i.e., the rear side of the first chamber 41), and under the action of the negative pressure, external low-temperature air continuously passes through the heat exchanger 2 (or passes through the left shell 14 and then passes through the heat exchange gas 2) to enter the first chamber 41, the low-temperature air fully exchanges heat with the heat exchanger 2 when passing through the heat exchanger 2, and then, the air flow after heat exchange is discharged out of the first chamber 41 from the air port 131 of the front shell 13 through the fan 6.

As shown in fig. 5 and 6, the side of the electrical control box 5 facing the heat exchanger 2 is a first side wall 51 of the electrical control box 5, and a gap is formed between the first side wall 51 and the heat exchanger 2, which gap is similar to an aisle and is used for air flow to pass through. Specifically, after heat exchange is performed on a portion of the heat exchanger 2 opposite to the first side wall 51, the external air flow enters the gap, and flows to the fan 6 from the gap, so that the external air flow can be discharged out of the first chamber 41 by the fan 6.

Because the first side wall 51 of the electronic control box 5 cannot abut against the end plate 21 of the heat exchanger 2 due to the arrangement of the gap, an opening is formed above the partition plate 3 and between the end plate 21 of the heat exchanger 2 and the first side wall 51 of the electronic control box 5, the opening enables the first chamber 41 and the second chamber 42 to be communicated, and if the opening is reserved, airflow enters the first chamber 41 from the second chamber 42 during the operation of the fan, so that the airflow passing through the heat exchanger is reduced, and the heat exchange efficiency of the heat exchanger 2 is reduced.

To solve this problem, as shown in fig. 6 to 8, the outdoor unit further includes a wind shielding assembly 8, the wind shielding assembly 8 is configured on the electric control box 5, and the wind shielding assembly 8 is used for blocking the air flow from the gap into the first chamber 41 from the second chamber 42. That is, by providing the wind shielding assembly 8, after the fan 6 generates negative pressure in the first chamber 41, the airflow in the second chamber 42 cannot flow into the first chamber 41 from the gap, and therefore, the external low-temperature air can only (or more) enter the first chamber 41 through the path passing through the heat exchanger 2, so that the total amount of the low-temperature air flowing through the heat exchanger 2 is increased, and the heat exchange efficiency of the heat exchanger 2 is further improved.

Preferably, as shown in fig. 7 and 8, the wind-shielding assembly 8 includes a plurality of baffles 81 arranged at intervals, the baffles 81 extending from the first side wall 51 toward a side adjacent to the heat exchanger 2. The baffle 81 provides a closure of the opening formed between the end plate 21 and the first side wall 51 above the partition 3, so that the flow of air from the second chamber 42 into the first chamber 41 can be prevented or greatly reduced.

Specifically, in this embodiment, the baffle 81 is disposed perpendicular to the first side wall 51, so that the wind shielding effect is better. Of course, in other embodiments, the baffle 81 may be disposed at an acute angle or an obtuse angle with respect to the first sidewall 51 according to actual needs, and is not limited herein.

Preferably, as shown in fig. 7, the lowest point of the at least one baffle 81 in the vertical direction is not higher than the upper end of the partition plate 3, so that the baffle 81 can completely cover the above opening size in the vertical direction, thereby better blocking the airflow from entering the first chamber 41 from the second chamber 42, and improving the heat exchange efficiency of the heat exchanger 2.

Further, as shown in fig. 8, the length of the plurality of baffles 81 along the vertical direction is arranged in a ladder manner, that is, the length of each baffle 81 along the vertical direction tends to gradually increase or gradually decrease. Preferably, the length of the baffle plate 81 close to the first chamber 41 in the vertical direction is greater than the length of the baffle plate 81 close to the second chamber 42 in the vertical direction, and the baffle plates 81 arranged in a step shape form a layer-by-layer blocking effect, so that the resistance of the wind blocking assembly 8 to the airflow is greater, and the airflow in the second chamber 42 is less likely to enter the second chamber 42.

Specifically, in the present embodiment, as shown in fig. 8, the wind shielding assembly 8 includes two baffles 81. As shown in fig. 7, the lowest point of the long baffle 81 in the vertical direction is flush with the upper end of the partition plate 3, and the baffle 81 is disposed so as to cover the opening. In other embodiments, the number of the baffles 81 may be increased appropriately, and the length of the baffles 81 in the vertical direction may also be increased.

Preferably, in this embodiment, the electronic control box 5 is made of a plastic material, and the wind shielding assembly 8 and the whole electronic control box 5 are integrally injection-molded, so that the processing and manufacturing are more convenient. Of course, in other embodiments, the electronic control box 5 may be made of a metal material, and the wind shielding assembly 8 is connected to the first side wall 51 by welding, which is not limited in this respect.

Preferably, as shown in fig. 7, the portion of the electronic control box 5 located in the first chamber 41 includes a heat dissipation fin 53, and the heat dissipation fin 53 is connected with a circuit board inside the electronic control box 5. Since the first chamber 41 contains air flowing at a high speed, the arrangement of the heat dissipation fins 53 in the first chamber 41 is beneficial to dissipating heat from the circuit board in the electrical control box 5.

Preferably, as shown in fig. 5, a first flange 1111 is disposed at the top 111 of the rear casing 11, the upper end of the electronic control box 5 further includes a lug part 52, the lug part 52 overlaps the first flange 1111 and is fixed to the first flange 1111 by a fastener, and the upper casing 12 covers the first flange 1111 and the lug part 52, so that the electronic control box 5 is fixedly installed, and the appearance of the outdoor unit is more beautiful. In other embodiments, two or more lugs 52 may be provided and are not limited thereto. It should be noted that the side wall of the electronic control box 5 opposite to the front shell 13 of the housing 1 abuts against the front shell 13, so as to ensure good sealing between the electronic control box 5 and the front shell 13, and prevent the airflow from flowing into the first chamber 41 from the second chamber 42.

Further, as shown in fig. 7 and 8, a second flange 31 is provided at the upper end of the partition plate 3, and the bottom of the electronic control box 5 abuts against the second flange 31. On one hand, the second flanging 31 can play a role in supporting the electric control box 5, and the installation reliability of the electric control box 5 is ensured. On the other hand, the second flange 31 abuts against the bottom of the electronic control box 5, so that the sealing performance between the first cavity 41 and the second cavity 42 is improved, that is, when the fan 6 works, the air flow is prevented from flowing from the position of the partition plate 3 and the bottom of the electronic control box 5 to the first cavity 41 from the second cavity 42, and the heat exchange efficiency of the heat exchanger 2 is further improved.

Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and for those skilled in the art, there may be variations on the specific embodiments and the application range according to the ideas of the present invention, and the contents of the present specification should not be construed as limitations to the present invention.
