Description

Technical Field

[0001] The utility model belongs to the technical field of heat pump units, and particularly relates to a heat pump unit. Background Art

[0002] A heat pump unit is a heat energy conversion device based on a compressor and a heat exchange structure. Through the heat pump unit, the temperature of the medium can be raised or lowered, and then cold and warm airflows can be generated. During the operation of the heat pump unit, the cooled refrigerant is pumped into the air-cooling device, and after heat exchange between the air-cooling device and the refrigerant, a cooling airflow is generated to cool the environment. Similarly, through the heat exchange between the heat medium pumped by the heat pump unit and a heating element such as a heating panel, the heating panel is heated to raise the temperature of the environment.

[0003] Since the heat pump unit is not only energy-saving and environmentally friendly, but also highly sensitive to environmental temperature regulation, its application in the industry has been gradually popularized. However, during the operation of the current heat pump unit, when the heat medium (such as water) exchanges heat with the heating panel, the heat exchange efficiency is low. The specific reason is that the path of the refrigerant through the heating panel is too short, resulting in the refrigerant being unable to quickly exchange heat with the heating panel. And due to the inability to quickly exchange heat, the heat exchange efficiency between the heating panel and the ambient air is low, resulting in an unsatisfactory heating effect of the heat pump unit on the environment during actual use. During the actual operation process, in order to quickly raise the environmental temperature, the heat pump unit operates at a high load in a short time, which not only consumes a large amount of energy but also generates a lot of noise.

[0004] During the cooling process, since the air-cooling device can adjust the wind speed, the cooling effect is relatively good. Therefore, due to the above-mentioned defects of the heat pump unit, the heating efficiency and effectiveness of the heat pump unit on the environment are not high. Summary of the Utility Model

[0005] Based on the above background, the purpose of the utility model is to provide a heat pump unit.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A heat pump unit includes a heat pump unit body, and a water outlet pipe and a water return pipe are respectively arranged on the heat pump unit body;

[0008] The water outlet end of the water outlet pipe is communicated with an air-cooling mechanism and a heat dissipation fin mechanism;

[0009] The water outlet ends of the air-cooling mechanism and the heat dissipation fin mechanism are respectively communicated with the water return pipe;

[0010] The heat dissipation fin mechanism includes a plurality of heat dissipation fin plates, and a heat dissipation flow channel with a folded structure is arranged in the heat dissipation fin plate;

[0011] The heat sink plates are connected through a series connection pipe, and the series connection pipe is connected to the heat dissipation channel;

[0012] The heat sink plate includes a first plate portion and a second plate portion hermetically integrated with the first plate portion;

[0013] On the side walls of the first plate portion and the second plate portion facing each other, folded flow grooves are respectively provided. When the first plate portion and the second plate portion are combined into one body, a heat dissipation channel is formed between the folded flow grooves.

[0014] Preferably, the water outlet end of the water outlet pipe is connected to a first pipe, and the first pipe has two water outlet ends, namely an upper water outlet end and a lower water outlet end;

[0015] The upper water outlet end is connected to the water inlet end of the heat sink plate, and the lower water outlet end is connected to the water inlet end of the air cooling mechanism.

[0016] Preferably, the water inlet end of the return pipe is connected to a second pipe, and the second pipe has two water inlet ends, namely an upper water inlet end and a lower water inlet end;

[0017] The upper water inlet end is connected to the water outlet end of the heat sink plate, and the lower water inlet end is connected to the water outlet end of the air cooling structure.

[0018] Preferably, a first valve for controlling the water outlet of the upper water outlet end is assembled and connected to the first pipe, and a second valve for controlling the water outlet of the lower water outlet end is assembled and connected to the first pipe.

[0019] Preferably, a third valve for controlling the water inlet of the upper water inlet end and a fourth valve for controlling the water inlet of the lower water inlet end are assembled and connected to the second pipe.

[0020] Preferably, a water replenishing tank is assembled and connected to the return pipe;

[0021] The water outlet end of the water replenishing tank is assembled and connected to a water replenishing pipe, and the water replenishing pipe is assembled and connected to the return pipe.

[0022] Preferably, the heat dissipation channel includes a plurality of vertically arranged vertical flow channel portions;

[0023] The vertical flow channel portions are sequentially connected through a plurality of arc-shaped flow channel portions arranged vertically and alternately;

[0024] The water outlet end and the water inlet end of the heat dissipation channels of different heat sink plates are connected through a series connection pipe.

[0025] Preferably, heat dissipation rib plates with a folded structure are fixedly connected to the side walls on both sides of the heat sink plate.

[0026] Preferably, the shape of the heat dissipation rib plate is the same as the shape of the heat dissipation channel;

[0027] The heat dissipation rib plate coincides with the projection of the heat dissipation flow channel on the vertical plane.

[0028] The utility model has the following beneficial effects:

[0029] 1. By providing folded flow grooves on the side walls of the first plate part and the second plate part of the heat dissipation fin plate facing each other, when the first plate part and the second plate part are combined into one body, heat dissipation flow channels are formed between the folded flow grooves. Specifically, the heat dissipation flow channels include a plurality of vertically arranged vertical flow channel parts; the vertical flow channel parts are sequentially connected through a plurality of arc-shaped flow channel parts arranged up and down in a staggered manner, so as to increase the coverage area of the heat dissipation flow channels on the heat dissipation fin plate through the heat dissipation flow channels designed in this shape, and further increase the total heat exchange area. At the same time, the time for the heat medium to pass through is increased. Under the action of connecting a plurality of heat dissipation fin plates in series, the total length of the heat dissipation flow channels is relatively large, so the heat exchange efficiency is very high.

[0030] 2. Since the heat dissipation rib plate (also in a folded shape) greatly increases the contact surface with air and has excellent heat conduction performance, during the working process, heat exchange with air is accelerated through the heat dissipation rib plate. Because the installation position of the heat dissipation rib plate corresponds to the position of the heat dissipation flow channel, during the heat exchange process, the heat dissipation efficiency between the heat dissipation flow channel with a high temperature and the heat dissipation rib plate is further accelerated.

[0040] Embodiment 1

[0041] As Figures 1-4 shown, a heat pump unit includes a heat pump unit body 2 (installed on a movable box body 1 in a conventional manner disclosed in the prior art to facilitate movement). The heat pump unit body 2 is a conventional heat pump unit disclosed in the prior art, and its main structure includes components such as a compressor, a heat exchanger, and a controller. Similar to the existing heat pump unit body 2, during the operation of the heat pump unit body 2, a refrigerant with a reduced temperature or a heat medium with an increased temperature is generated. To pump the refrigerant or the heat medium with an increased temperature, in the same way as the existing method, a water outlet pipe 61 is respectively provided on the heat pump unit body 2. At the same time, the circulating medium passes through a return water pipe 62 assembled and connected on the heat pump unit body 2 and circulates back to the heat pump unit body 2.

[0042] The water outlet end of the above-mentioned water outlet pipe 61 is connected to an air-cooling mechanism and a heat sink mechanism.

[0043] Specifically, in order to increase the heat exchange efficiency between the heat medium pumped out by the heat pump unit body 2 and the heat sink mechanism and raise the ambient temperature in a short time, the specific structure of the above-mentioned heat sink mechanism is as follows:

[0044] The heat sink mechanism includes several heat sink plates 3, and a folded heat dissipation channel A is formed inside the heat sink plate 3.

[0045] Specifically, the heat sink plates 3 are connected through a series connection pipe 34, and the series connection pipe 34 is connected to the heat dissipation channel A.

[0046] Meanwhile, the forming method of the heat dissipation channel A is as follows: the heat sink plate 3 includes a first plate portion and a second plate portion hermetically integrated with the first plate portion (the first plate portion and the second plate portion have the same shape, and after combination, they form the heat sink plate 3. Specifically, after industrial production, the first plate portion and the second plate portion are hermetically welded).

[0047] On the side walls of the first plate portion and the second plate portion facing each other, folded flow grooves are respectively formed. When the first plate portion and the second plate portion are combined into one body, the heat dissipation channel A is formed between the folded flow grooves.

[0048] Specifically, the heat dissipation channel A includes several vertically arranged vertical channel portions; the vertical channel portions are sequentially connected through several arc-shaped channel portions arranged vertically and alternately.

[0049] Through the heat dissipation channel A designed in this shape, the coverage area of the heat dissipation channel A on the heat sink plate 3 is increased, thereby increasing the total heat exchange area. At the same time, the time for the heat medium to pass through is increased. Under the action of the series connection mode of multiple heat sink plates 3, the total length of the heat dissipation channel A is relatively large, so the heat exchange efficiency is very high.

[0050] Specifically, the water outlet end and the water inlet end of the heat dissipation channel A of different heat sink plates 3 are connected through the series connection pipe 34. The connection mode is: the series connection pipe 34 connects the water outlet end and the water inlet end of the heat dissipation channel A on adjacent heat sink plates 3.

[0051] Meanwhile, an inlet pipe 31 connecting the water inlet end of the heat dissipation channel A is connected to the first heat sink plate 3, and an outlet pipe 32 connecting the water outlet end of the heat dissipation channel A is connected to the last heat sink plate 3.

[0052] Meanwhile, the upper and lower ends of the heat sink plate 3 are connected in series through an installation cross beam 33, and both ends of the installation cross beam 33 are fastened to an installation frame through bolts 331.

[0053] Embodiment 2

[0054] As Figures 1-4 shown, on the basis of the structure of Embodiment 1 in this embodiment, the water outlet end of the water outlet pipe 61 is connected to a first pipe 63, and the first pipe 63 has two water outlet ends, namely an upper water outlet end and a lower water outlet end;

[0055] The upper water outlet end is connected to the water inlet end of the heat sink plate 3 (i.e., on the inlet pipe 31), and the lower water outlet end is connected to the water inlet end of the air cooling mechanism.

[0056] Through, a second pipe 65 is connected to the water inlet end of the return pipe 62. The second pipe 65 has two water inlet ends, namely an upper water inlet end and a lower water inlet end.

[0057] The upper water inlet end is connected to the water outlet end of the heat sink plate 3 (i.e., on the outlet pipe 32), and the lower water inlet end is connected to the water outlet end of the air cooling structure.

[0058] Meanwhile, a first valve 74 for controlling the water outlet of the upper water outlet end is assembled and connected to the first pipe 63, and a second valve 71 for controlling the water outlet of the lower water outlet end is assembled and connected to the first pipe 63.

[0059] A third valve 73 for controlling the water inlet of the upper water inlet end and a fourth valve 72 for controlling the water inlet of the lower water inlet end are assembled and connected to the second pipe 65.

[0060] During the working process, when it is necessary to raise the temperature of the environment, at this time, the third valve 73 and the fourth valve 72 are closed, and the first valve 74 and the second valve 71 are opened. The heat medium pumped out by the heat pump unit body 2 passes between the heat sink plates 3 in the above-mentioned manner and quickly exchanges heat with the heat sink plates 3, and the quickly heated heat sink plates 3 exchange heat with the air in the environment to achieve rapid heating.

[0061] Similarly, during the cooling process, the first valve 74 and the second valve 71 are closed, and the third valve 73 and the fourth valve 72 are opened. The refrigerant pumped out by the heat pump unit body 2 enters the air cooling mechanism 4. Among them, the air cooling mechanism 4 is a conventional air cooling device disclosed in the prior art, and its main structure includes a coil (the coil is installed in the fan housing). The refrigerant enters the coil (not shown in the figure), and the air flow is driven by a fan (not shown in the figure) installed on the fan housing to exchange heat with the low-temperature coil.

[0062] Finally, both the refrigerant or the heat medium circulate back to the heat pump unit body 2 through the return pipe 62.

[0063] During the actual working process, in order to supplement the medium, a water replenishing tank 5 is assembled and connected to the above-mentioned return pipe 62; the water outlet end of the water replenishing tank 5 is assembled and connected to a water replenishing pipe 64 (similarly, a valve is installed on the water replenishing pipe 64), and the water replenishing pipe 64 is assembled and connected to the return pipe 62.

[0064] Embodiment 3

[0065] Such as Figures 1-4As shown in the figure, on the basis of the structure of Embodiment 1, folded heat dissipation rib plates 35 are fixedly connected to the side walls on both sides of the heat sink plate 3. The shape of the heat dissipation rib plate 35 is the same as that of the heat dissipation channel A; the projection of the heat dissipation rib plate 35 on the vertical plane coincides with that of the heat dissipation channel A. The heat dissipation rib plate 35 is made of copper with excellent thermal conductivity.

[0066] Since the heat dissipation rib plate 35 (also in a folded shape) greatly increases the contact surface with the air and has excellent thermal conductivity, during the working process, heat exchange with the air is accelerated through the heat dissipation rib plate 35. Because the installation position of the heat dissipation rib plate 35 corresponds to that of the heat dissipation channel A, during the heat exchange process, the heat dissipation efficiency of the heat dissipation channel A at the position with a higher temperature is further accelerated with the heat dissipation rib plate 35.

[0067] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
