Technical Field

[0001] This utility model relates to the technical field of heat pump units, specifically to a cold air duct for a heat pump unit. Background Technology

[0002] A heat pump unit is an energy-saving device that utilizes heat from a low-grade heat source and, driven by a small amount of high-grade energy, raises the temperature to a higher level. Depending on the heat source, they can be divided into air-source, water-source, and ground-source heat pumps, and are widely used for heating, cooling, and hot water supply in residential, commercial, and industrial settings. The cold air duct is one of the key components of a heat pump unit, primarily used to dissipate indoor heat to the outdoors during summer cooling.

[0003] According to Chinese Patent No. CN222278929U, a cold air channel for a combined multi-heat pump unit includes a cavity, one end of which is closed and the other end is open to form an exhaust port; support sides are provided on both sides of the cavity, and the bottom of the support sides contacts the top side edge of the heat pump unit; multiple connection openings are provided at equal intervals along the length direction at the bottom of the cavity, and the connection openings are used to connect to the cold air exhaust port on the top of the heat pump unit.

[0004] The above scheme uses a single cold air duct to connect multiple heat pump units, which results in the following drawbacks: the cold air duct is a single unit and cannot be divided, so the number of heat pump units corresponding to one cold air duct is fixed, making it unsuitable for various environments and reducing the applicability of the heat pump units. Utility Model Content

[0005] The purpose of this invention is to provide a cold air channel for a heat pump unit, so as to solve the problem that the number of heat pump units corresponding to one cold air channel is fixed, which cannot be applied to various environments and reduces the applicability of heat pump units.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a cold air channel for a heat pump unit, comprising two cold air channel bodies, the two cold air channel bodies being respectively disposed on the top surfaces of two heat pump unit bodies, connecting plates being fixed on both sides of the cold air channel bodies, positioning plates being fixed on both sides of the cold air channel bodies, a threaded hole being provided on one side of the positioning plate, a fixing bolt being rotatably inserted into the connecting plate, and one end of the fixing bolt passing through the connecting plate and being threadedly connected to the threaded hole.

[0007] Preferably, the top surface of the heat pump unit body is provided with a cold air hole, and the bottom surface of the cold air duct body is provided with a ventilation hole, and the central axis of the cold air hole and the ventilation hole are on the same straight line.

[0008] Preferably, a mounting plate is detachably provided at the left end of the leftmost cold air duct body, and a mounting hole is provided on one side of the mounting plate, and an exhaust fan is installed inside the mounting hole.

[0009] Preferably, fixing plates are fixed on both sides of the mounting plate, the fixing plates and fixing bolts are rotatably inserted, and one end of the fixing bolt passes through the fixing plate and is threadedly connected to the threaded hole.

[0010] Preferably, a sealing groove is provided on the left side of the cold air duct body, and a sealing frame is fixed on the right side of the cold air duct body. The sealing frame on the right side of the left cold air duct body and the sealing groove on the left side of the right cold air duct body are slidably configured.

[0011] Preferably, a fixing ring is fixed to one side of the mounting plate, and a filter screen is fixed inside the fixing ring.

[0012] Compared with existing technologies, the cold air duct of a heat pump unit that adopts the above technical solution has the following beneficial effects:

[0013] 1. When installing the heat pump unit, the staff will splice and install the corresponding number of cold air duct bodies according to the number of heat pump unit bodies. When two cold air duct bodies are spliced ​​together, the connecting plate will approach the positioning plate. Then, the staff will pass the fixing bolt through the connecting plate and screw it into the threaded hole. As the fixing bolt is screwed into the threaded hole, it will drive the connecting plate to move closer to the positioning plate, thereby completing the splicing and installation of the cold air duct body. The staff will install the corresponding number of cold air duct bodies according to the number of heat pump unit bodies required, which increases the applicability of the heat pump unit's cold air duct.

[0014] Second, the staff will install the mounting plate on the left side of the leftmost cold air duct body, and use the exhaust fan to increase the airflow inside the cold air duct body, thus accelerating the flow of cold air inside the cold air duct body.

[0015] Third, when two cold air duct bodies are spliced ​​together, the sealing frame will fill the interior of the sealing groove. Since the surface of the sealing frame will fit tightly against the inner wall of the sealing groove, the sealing between the two cold air duct bodies can be increased. The filter screen can effectively prevent insects and animals from entering the interior of the cold air duct body, thus improving the hygiene and safety of the interior of the cold air duct body.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown, a cold air duct for a heat pump unit includes two cold air duct bodies 1, both of which have an arched top. The two cold air duct bodies 1 are respectively installed on the top surfaces of two heat pump unit bodies 6. Connecting plates 2 are fixed on both sides of the cold air duct body 1, and positioning plates 3 are fixed on both sides of the cold air duct body 1. A threaded hole 4 is provided on one side of the positioning plate 3. A fixing bolt 5 is rotatably inserted into the connecting plate 2. One end of the fixing bolt 5 passes through the connecting plate 2 and is threadedly connected to the threaded hole 4. A cold air hole 7 is provided on the top surface of the heat pump unit body 6, and a ventilation hole 8 is provided on the bottom surface inside the cold air duct body 1. The central axes of the cold air hole 7 and the ventilation hole 8 are on the same straight line.

[0023] During use, when installing the heat pump unit body 6, the staff will splice and install the corresponding number of cold air duct bodies 1 together according to the number of heat pump unit bodies 6. When two cold air duct bodies 1 are spliced ​​together, the connecting plate 2 will approach the positioning plate 3. Then, the staff will pass the fixing bolt 5 through the connecting plate 2 and screw it into the threaded hole 4. As the fixing bolt 5 is screwed into the threaded hole 4, it will drive the connecting plate 2 to move closer to the positioning plate 3, thereby completing the splicing and installation of the cold air duct body 1. The staff will install the corresponding number of cold air duct bodies 1 according to the number of heat pump unit bodies 6 required, which increases the applicability of the heat pump unit's cold air duct.

[0024] like Figure 2 and Figure 4 As shown, a mounting plate 9 is detachably installed on the left end of the leftmost cold air duct body 1. A mounting hole 10 is opened on one side of the mounting plate 9. An exhaust fan 11 is installed inside the mounting hole 10. Fixing plates 12 are fixed on both sides of the mounting plate 9. The fixing plates 12 and fixing bolts 5 are rotatably inserted. One end of the fixing bolts 5 passes through the fixing plate 12 and is threadedly connected to the threaded hole 4.

[0025] During use, the staff will install the mounting plate 9 on the left side of the leftmost cold air duct body 1, and use the exhaust fan 11 to increase the airflow inside the cold air duct body 1, thereby accelerating the flow speed of the cold air inside the cold air duct body 1.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, a sealing groove 13 is provided on the left side of the cold air duct body 1, and a sealing frame 14 is fixed on the right side of the cold air duct body 1. The sealing frame 14 on the right side of the left cold air duct body 1 and the sealing groove 13 on the left side of the right cold air duct body 1 are slidably arranged. A fixing ring 15 is detachably fixed on one side of the mounting plate 9, and a filter screen 16 is fixed inside the fixing ring 15.

[0027] In use, when the two cold air duct bodies 1 are spliced ​​together, the sealing frame 14 will fill the interior of the sealing groove 13. Since the surface of the sealing frame 14 will be tightly attached to the inner wall of the sealing groove 13, the sealing between the two cold air duct bodies 1 can be increased. The filter screen 16 can effectively prevent insects and animals from entering the interior of the cold air duct body 1, thus improving the hygiene and safety of the interior of the cold air duct body 1.
