Description

Technical Field

[0001] The utility model relates to the technical field of heat pump units, in particular to a cold air channel of a combined multi-heat pump unit. Background Art

[0002] The air-cooled heat pump unit is a circulation system composed of a compressor, a heat exchanger, a throttle, a heat absorber and a compressor. The refrigerant circulates in the system under the action of the compressor. The continuous circulation of the refrigerant realizes the process of converting the low-temperature heat in the air into high-temperature heat and heating the cold water.

[0003] When multiple heat pump units are used in large-scale seed processing systems, corresponding exhaust ducts are set for each heat pump unit. In this case, multiple openings need to be opened on the wall structure, and the duct structure is relatively fixed, which requires more exhaust air ducts for the heat pump units.

[0004] At the same time, most of the existing channels are made of metal. When the heat pump unit is working, the surface in contact with the external environment is prone to condensation water flowing to the surface of the heat pump unit. Therefore, in actual production, it is inconvenient to design a cooling air outlet for each heat pump unit separately.

[0005] In summary, the existing cold air discharge problem for multiple heat pump units has the problem that most of the exhaust vents are independently set, which makes the construction complicated and the condensed water easily flows back into the heat pump unit. Summary of the invention

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1 , Figure 2 As shown, the utility model provides a cold air channel of a combined multi-heat pump unit, comprising:

[0031] The cavity 10 has one end that is closed and the other end that is open to form an exhaust port;

[0032] Support side surfaces 20 are provided on both sides of the cavity 10, and the bottom of the support side surfaces 20 contacts the top side edge of the heat pump unit 30;

[0033] The bottom of the cavity 10 is provided with a plurality of connection openings 40 at equal intervals along the length direction. The connection openings 40 are used to connect to the cold air outlet at the top of the heat pump unit 30 .

[0034] The utility model connects the cooling air outlets of multiple heat pump units through a cavity 10, thereby connecting the cooling air outlets of multiple heat pump units and exhausting the air through an exhaust port. A single cooling air outlet can reduce the construction requirements for the wall. Even if condensed water is formed on the inner wall of the cavity 10, it will be discharged through the connecting opening 40 under the action of the unidirectional airflow of the cavity 10.

[0035] Furthermore, the cavity 10 in the utility model includes an arc-shaped upper cover 11, a bottom wall 12 is arranged below the arc-shaped upper cover 11, the bottom wall 12 includes a horizontal bottom surface 13, both sides of the horizontal bottom surface 13 are connected with first inclined surfaces 14, and the side of the first inclined surface 14 away from the horizontal bottom surface 13 is connected to the bottom side of the arc-shaped upper cover 11.

[0036] Among them, multiple connecting openings 40 are arranged at equal intervals on the horizontal bottom surface 13. The purpose is that when the interior of the arc-shaped upper cover 11 is in operation of the heat pump unit 30, the first inclined surface 14 can slide the generated condensed water along its surface under the action of gravity, thereby collecting the condensed water.

[0037] To further illustrate, the arc-shaped upper cover 11 of the utility model includes an outer cover body 111 and an inner cover body 112, the bottom edge of the inner cover body 112 is connected to the top side of the first inclined surface 14, and the bottom side of the outer cover body 111 is connected to the horizontal bottom surface 13 and the first inclined surface 14 through the second inclined surface 15.

[0038] Among them, the outer cover body 111, the second inclined surface 15 on both sides of the outer cover body 111, the inner cover body 112 and the first inclined surface 14 on both sides of the inner cover body 112 form an isolation cavity 113. The purpose of the isolation cavity 113 is to enable the cavity 10 formed in the inner cover body 112 to isolate the external environment, thereby preventing condensation water from forming on the outer surface of the arc-shaped upper cover 11.

[0039] One side of the first inclined surface 14 is connected to the side of the horizontal bottom surface 13 through a hollow mesh segment 114 , and the other side of the first inclined surface 14 is connected to the bottom side of the inner cover body 112 through a hollow mesh segment 114 .

[0040] Therein, at least one portion of the isolation cavity 113 is provided with a connecting pipe hole 115 , and one end of the isolation cavity 113 is provided with an air inlet.

[0041] Furthermore, when the utility model specifically constructs the cavity 10, an inner cover body 112 is formed by a plurality of arc-shaped supports 50 arranged in parallel and a first skin 60 covering the plurality of arc-shaped supports 50, wherein the first skin 60 can specifically be made of nylon cloth, and the first skin 60 can cover the interior of the arc-shaped supports 50.

[0042] Vertical support rods 70 are disposed at the bottom of both sides of the arc-shaped bracket 50 , and the side edges of the first skin 60 extend to the bottom of the vertical support rods 70 to form a supporting side surface 20 .

[0043] A second skin 80 is disposed above the first skin 60 , and the second skin 80 is used to form an outer cover body 111 .

[0044] Of course, in the present invention, the outer cover 111 and the supporting side 20 can also be formed by covering the second skin 80 on the arc-shaped bracket 50 and the vertical support rod 70. That is, the first skin 60 does not construct its arc shape through the metal frame or the arc-shaped bracket 50. When the cold air discharged from the heat pump unit 30 enters the cavity 10, it will support the shape of the inner cover 112.

[0045] Of course, the purpose of the utility model is to achieve isolation of the cold air in the cavity 10 from the external environment by injecting an airflow with a temperature higher than that discharged by the heat pump unit 30 into the isolation cavity 113, so that condensation water will be formed on the inner wall of the inner cover body 112 or the isolation cavity 113, and the condensation water will be enriched on the inner wall of the isolation cavity 113 and then aggregated to form droplets, which will fall into the space between the first inclined surface 14 and the second inclined surface 15 under the action of gravity, and the condensation water formed on the first inclined surface 14 or the inner wall surface of the inner cover body 112 will enter the space formed between the first inclined surface 14 and the second inclined surface 15 through the hollow mesh segment 114.

[0046] Furthermore, the cavity formed between the first inclined surface 14 and the second inclined surface 15 in the utility model is tilted as a whole, and is tilted toward the end where the connecting pipe hole 115 is located. The condensed water in the cavity formed between the first inclined surface 14 and the second inclined surface 15 can be more easily discharged through the connecting pipe hole 115, and the connecting pipe hole 115 is connected to the pipeline.

[0047] Furthermore, since the cavity formed between the first inclined surface 14 and the second inclined surface 15 is provided with an air inlet at the end away from the connecting pipe hole 115, the condensed water in the cavity between the first inclined surface 14 and the second inclined surface 15 is blown toward the end where the connecting pipe hole 115 is located, thereby facilitating the discharge of the condensed water.

[0048] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
