Description

Technical Field

[0001] The utility model relates to the field of heat pumps, in particular to a vertical air source heat pump outdoor unit. Background Art

[0002] An air source heat pump is a new energy device that uses the reverse Carnot principle to convert low-grade heat energy in the atmosphere into high-grade heat energy for use while consuming less electricity. This makes it more energy-efficient than traditional heating equipment, and can be used, for example, for heating. The four core components of an air source heat pump are: an evaporator, a compressor, a condenser, and a throttle. The four are connected in sequence to form a loop for the circulation of refrigerant. The evaporator is placed outdoors to absorb heat energy from the atmosphere, while the condenser is placed indoors to release heat energy. For household air source heat pumps, the four components are usually divided into two modules, namely an outdoor unit and an indoor unit. The outdoor unit includes: an evaporator, a compressor, and a throttle. The indoor unit includes: a condenser. Usually, in order to promote the heat exchange efficiency between the equipment and the air in the environment, fans are installed in both the outdoor unit and the indoor unit.

[0003] The airflow design of the traditional air source heat pump outdoor unit is generally to set the air inlet on the back and one side of the outdoor unit (the other side is used to install the compressor, throttle, and control panel, etc., which needs to be sealed from the outside), and the air outlet is set on the front of the outdoor unit. The fan is set at the air outlet, and the air inside the outdoor unit is discharged to the outside by the fan, so that negative pressure is generated inside the outdoor unit, forcing the outside air to enter the outdoor unit from the back and side of the outdoor unit to exchange heat with the evaporator. The disadvantage of this traditional design is that most of the current household air source heat pump outdoor units are generally mounted on the outer wall, which means that the back of the air source heat pump outdoor unit is usually close to the wall. This installation method greatly reduces the air intake efficiency of the air inlet on the back of the air source heat pump outdoor unit, so that the outside air mainly relies on the side air inlet to enter, resulting in the thermal efficiency of the air source heat pump being weakened. Utility Model Content

[0004] Based on this, the utility model provides a vertical air source heat pump outdoor unit, adjusts the installation layout of the compressor, evaporator, and throttle, improves the air path, so that external air can enter from the bottom and both sides, improves the air intake efficiency, and achieves the purpose of improving the thermal efficiency of the air source heat pump.

[0007] An inner frame is arranged around the outer periphery of the evaporator; the inner frame is arranged in a vertical direction;

[0008] The outer shell is mounted on the periphery of the inner frame; the outer shell includes: a middle frame, a front cover, a back cover, and a top cover; the middle frame is arranged in a vertical direction and surrounds the periphery of the inner frame, and the periphery of the middle frame is provided with ventilation holes; the front cover is located on the front of the middle frame and has mesh holes; the back cover is located on the back of the middle frame and is a sealing plate structure; the top cover is an inverted U-shaped groove structure and is located on the top of the middle frame; a storage cavity is formed between the top cover and the middle frame;

During operation, the fan runs to generate negative pressure at the center of the U-shaped opening of the evaporator, forcing the external air to form an airflow from the sides and bottom of the middle frame from the outside to the inside. The airflow contacts the evaporator during circulation to achieve heat exchange, and is discharged from the mesh holes of the cover after the heat exchange. At the same time, since there are also air vents on the top of the middle frame, the heat generated by the control panel during operation will also be brought into the middle frame and quickly discharged with the help of airflow. Through the above design, the installation layout of the compressor, evaporator, and throttle is adjusted, and the air path is improved so that external air can enter from the bottom and both sides, thereby improving the air intake efficiency and achieving the purpose of improving the thermal efficiency of the air source heat pump.

[0040] like Figures 1 to 6 As shown, it is a vertical air source heat pump outdoor unit 100 according to an embodiment of the present invention.

[0041] like Figures 1 to 4 As shown, the vertical air source heat pump outdoor unit 100 includes: an evaporator 10, an inner frame 20 arranged around the outer periphery of the evaporator 10, an outer shell 30 arranged on the outer periphery of the inner frame 20, a fan 40 installed on the inner frame 20, a compressor (not shown) installed on the top of the outer shell 30, a throttle (not shown) connected to the compressor, and a control panel (not shown), and the control panel is respectively connected to the fan 40, the compressor, and the throttle. The inner frame 20 is used to provide rigid support. The outer shell 30 is used to protect the evaporator 10, the fan 40, the compressor, and the throttle. The evaporator 10, the compressor, and the throttle are part of the heat exchange circuit. The fan 40 is used to improve the heat exchange efficiency.

[0042] Below, combined Figures 1 to 6 , the above-mentioned vertical air source heat pump outdoor unit 100 is further explained.

[0043] like Figure 3 、 Figure 5 ,as well as Figure 6 The evaporator 10 is a U-shaped structure with the opening facing upward. Figure 6 As shown, the evaporator 10 includes: a plurality of heat dissipation fins 11 distributed in an array and heat pipes 12 passing through each heat dissipation fin 11. The heat dissipation fins 11 are arranged in a vertical direction.

[0044] like Figure 4 and Figure 5 As shown, the inner frame 20 is arranged in the vertical direction. Figure 4 As shown, in this embodiment, the inner frame 20 includes: a plurality of spaced-apart U-shaped frames 21 and bridge plates 22 connecting two adjacent frames 21. The combination of frames 21 and bridge plates 22 can reduce material usage, lower costs and overall equipment weight, while providing more channels for air circulation.

[0045] Considering that the frame is located between the evaporator 10 and the middle frame 31, it has a certain obstruction effect on the flow of air. Figure 4 As shown, in this embodiment, air guide holes 221 can be provided on both sides of the inner frame 20. The air guide holes 221 can also reduce airflow obstruction between the inner frame 20 and the evaporator 10 and the middle frame 31, thereby improving air intake efficiency. For example, in this embodiment, the air guide holes 221 are provided on the bridging plate 22.

[0046] like Figure 3 and Figure 4 As shown, the outer shell 30 includes a middle frame 31, a front cover 32, a back cover 33, and a top cover 34. The middle frame 31 is arranged vertically and surrounds the inner frame 20. Ventilation holes 311 are provided on each side of the middle frame 31. The front cover 32 is located on the front of the middle frame 31 and is provided with mesh holes 321. The back cover 33 is located on the back of the middle frame 31 and is a sealed plate structure. The top cover 34 is an inverted U-shaped groove structure and is located on top of the middle frame 31. A storage cavity 35 is formed between the top cover 34 and the middle frame 31.

[0047] To facilitate assembly and disassembly, in this embodiment, the front cover 32, back cover 33, and top cover 34 are all snap-connected to the middle frame 31. The snap-connection method facilitates assembly and disassembly. In other embodiments, to further enhance the stability of the connection, screws can also be used.

[0048] like Figure 3 and Figure 5 As shown, the fan 40 is located at the center of the opening area of ​​the evaporator 10 and is arranged opposite the mesh 321 , and the axial direction of the fan 40 is perpendicular to the placement direction of the heat dissipation fins 11 .

[0049] Here, you can combine Figure 4 As shown, in this embodiment, the compressor is located in the receiving chamber 35 and is connected to the heat pipe 12. The throttle and the control board are also located in the receiving chamber 35.

[0050] Considering that the compressor generates significant noise when in operation, in this embodiment, the outside of the compressor is wrapped with sound insulation cotton, which can reduce noise and vibration of the compressor.

[0051] In addition, in some embodiments, the control board is provided with a radiator (e.g., a heat dissipation fin group), and the radiator extends through the top of the middle frame 31 and then extends downward. The radiator can be used to quickly introduce the heat generated by the control board into the working area of ​​the evaporator 10.

[0052] In order to facilitate users to install the device on the wall, Figure 2 As shown, in this embodiment, the vertical air source heat pump outdoor unit 100 may further include a stand 50 connected to the housing 30. The stand 50 is an L-shaped structure and is disposed close to the bottom and back of the housing 30. The stand 50 facilitates mounting the device on a wall.

[0053] Furthermore, the tripod 50 can be detachably connected to the housing 30 by screws. The screw connection method has good stability and is easy to assemble and disassemble.

[0054] Brief description of working principle:

[0055] like Figure 3 As shown, the compressor and the throttle are installed above the evaporator 10. During operation, the fan 40 runs to generate negative pressure at the center of the U-shaped opening of the evaporator 10, forcing the external air to form an airflow from the sides and bottom of the middle frame 31 from the outside to the inside into the middle frame 31. The airflow flows through the gaps between the heat dissipation fins 11 of the evaporator 10, quickly taking away the heat, thereby achieving heat exchange, and after the heat exchange, it is discharged from the mesh 321 of the cover 32. At the same time, since the top of the middle frame 31 is also provided with an air vent 311, the heat generated by the control panel during operation will also be brought into the middle frame 31 and quickly discharged with the help of the airflow. This design abandons the traditional air inlet on the back, makes full use of the sides and bottom, and also makes full use of the heat generated by the control panel during operation, thereby improving the thermal efficiency of the equipment.

[0056] Furthermore, considering that the compressor is moved to the top position of the equipment, an inner frame 20 is introduced to ensure structural stability.

[0057] The above-mentioned vertical air source heat pump outdoor unit 100 adjusts the installation layout of the compressor, evaporator 10, and throttle, and improves the air path so that external air can enter from the bottom and both sides, thereby improving the air intake efficiency and achieving the purpose of improving the thermal efficiency of the air source heat pump.

[0058] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above 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.

[0059] The above embodiments merely represent preferred implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
