Abstract

This utility model discloses a novel heat exchanger and a heat dissipation unit and a novel cabin containing the heat exchanger, belonging to the field of refrigeration technology. It includes a fan and a heat exchange component. The fan has an air inlet at its bottom and an air outlet on its side wall. The heat exchange component includes a heat exchange tube disposed at the bottom of the fan, aligned with the air inlet. A cooling medium flows through the heat exchange tube, allowing heat exchange between the air and the cooling medium. Correspondingly, a heat dissipation unit and a novel cabin are also disclosed.

Description

Technical Field

[0001] This utility model belongs to the field of refrigeration technology, specifically relating to a novel heat exchanger and a heat dissipation unit and a novel compartment containing it. Background Technology

[0002] As people's living standards improve, home-use cabins are becoming increasingly popular, with various types of cabins, including hyperbaric oxygen chambers, atmospheric oxygen chambers, and safety cabins, attracting widespread attention.

[0003] Currently, due to limitations imposed by the home environment, the size of the cabin structure itself is also limited, and its internal space is also limited, making it impossible to install various large equipment. Alternatively, these large equipment may occupy most of the cabin space, severely compressing the internal activity space and bringing a poor user experience. Cooling equipment is a key focus among these large equipment.

[0004] Existing cooling equipment often uses integrated air conditioners, which can reduce the overall space occupied, but for ease of installation, they are often placed at the bottom of the cabin, and their cooling effect is not good. On the other hand, split cooling systems have heat exchangers that occupy a large amount of top space, which seriously affects the living space of people inside the cabin.

[0005] Therefore, there is an urgent need for a heat exchanger that occupies less space and can be used in cabin structures. Utility Model Content

[0006] In view of one or more of the above-mentioned defects or improvement needs of the prior art, this utility model provides a new type of heat exchanger and a heat dissipation unit and a new type of cabin containing the heat exchanger. The new heat exchanger with lower installation height requirements can be installed in various cabin structures, saving cabin space.

[0007] To achieve the above objectives, this utility model provides a novel heat exchanger, which includes a fan and a heat exchange assembly. The fan has an air inlet at its bottom and an air outlet on either side of its wall. The heat exchange assembly includes a fixed base and a heat exchange tube disposed on the fixed base. The fixed base is connected to the bottom of the fan, and the heat exchange tube is aligned with the air inlet. One end of the heat exchange tube is the inlet end, and the other end is the outlet end, used to inlet and outlet the cooling medium, so that air can exchange heat with the cooling medium in the heat exchange tube and be discharged through the air outlet.

[0008] As a further improvement of this utility model, the fan includes a fan housing, a rotating shaft, an impeller, and a drive motor. The rotating shaft is disposed inside the fan housing, and both ends of the rotating shaft are rotatably connected to the fan housing. One end of the rotating shaft is the driving end and is connected to the driving motor. The impeller is sleeved on the outer peripheral wall of the rotating shaft. The air inlet and the air outlet are respectively positioned facing the outer peripheral wall of the rotating shaft.

[0009] As a further improvement of this utility model, the rotating shaft extends along a first direction, and the lengths of the air inlet and the air outlet in the first direction are the same as the length of the rotating shaft.

[0010] As a further improvement of this utility model, the heat exchange tube includes a plurality of heat exchange units arranged in series, the heat exchange units extending along the first direction, and each heat exchange unit being arranged at intervals along the second direction.

[0011] As a further improvement of this utility model, the fixing base includes two end plates and a connector connecting the two end plates. The two end plates are respectively connected to the two ends of the fan, and multiple through holes are provided on the end plates. The two ends of the heat exchange unit are respectively inserted into the through holes of the two end plates, so that the end of the heat exchange unit is located on the side of the end plate away from the other end plate, and the ends of two adjacent heat exchange units are connected by a bent pipe.

[0012] As a further improvement of this utility model, a water receiving tray is provided at the bottom of the heat exchange component for receiving condensate. And / or, A guide pipe is provided corresponding to the air outlet to guide the cold air discharged by the fan.

[0013] As a further improvement of this utility model, the height of the heat exchange component is 10~15mm, and the height of the fan is 40~45mm.

[0014] Another aspect of this utility model provides a heat dissipation unit, including at least one of the novel heat exchangers described above. It also includes a heat dissipation unit, which is connected to the heat exchange component through a cooling medium pipeline, so that the cooling medium can absorb ambient heat in the new heat exchanger, flow back into the heat dissipation unit, and release heat through the heat dissipation unit.

[0015] Another aspect of this utility model is to provide a novel cabin, including the aforementioned heat dissipation unit. It also includes the cabin; A partition is provided on the top of the cabin to divide the interior space into a first space and a second space. The novel heat exchanger is installed in the first space, and a guide pipe is provided corresponding to the air outlet. One end of the guide pipe is connected to the air outlet, and the other end is connected to the second space. The heat dissipation unit is installed in the second space, and a heat exhaust pipe is provided corresponding to the heat dissipation unit. The heat exhaust pipe connects the inside and outside of the chamber to exhaust the waste heat released by the heat dissipation unit.

[0016] As a further improvement of this utility model, a grid is provided at the end of the guide pipe away from the air outlet. The above-mentioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0017] In summary, the technical solutions conceived by this utility model have the following beneficial effects compared with the prior art: (1) The novel heat exchanger of this utility model sets the air inlet at the bottom of the fan and sets a heat exchange component corresponding to the air inlet. The cross section of the air inlet is perpendicular to the height direction, and the heat exchange component is set directly opposite the air inlet. This makes the length and width of the heat exchange component and the air inlet match each other on the horizontal plane. The height (i.e. the heat exchange path of the air in the heat exchange component) is not affected by the size of the fan. The height only needs to meet the heat exchange requirements of the air in the heat exchange component, thereby reducing the height requirement of the heat exchange component. Consequently, the installation height requirement of the entire heat exchanger is also reduced. This allows the novel heat exchanger to be set in the top space of the cabin, so that the heat exchanger can discharge cold air from the top down into the personnel activity space to bring a comfortable experience to the personnel. (2) The novel heat exchanger of this utility model extends the shaft in the fan along the first direction, and sets the overall structure of the fan and the heat exchange components to match it, thereby increasing the air volume per unit time and improving the cooling efficiency of the heat exchanger. (3) The novel heat exchanger of this utility model has a heat exchange tube comprising multiple heat exchange units. The length and width of the air inlet are respectively related to the length and number of heat exchange units. It is further clarified that the height of the heat exchange component is related to the number of rows of heat exchange units in the height direction and the diameter of the heat exchange unit. This ensures that when multiple heat exchange units and longer heat exchange units are arranged, the overall height of the heat exchange tube will not be affected, so as to improve the cooling efficiency of the heat exchanger while maintaining a constant height of the heat exchange component. (4) The novel heat exchanger of this utility model sets the heat exchange units in two rows spaced apart along the height direction, and the projections of the heat exchange units in the first row and the second row on the bottom surface of the fan housing are staggered, thereby ensuring that the air entering the air inlet undergoes heat exchange and is cooled down. The arrangement of the two rows of heat exchange units allows the height of the heat exchange components to be 10~15mm, and further compresses the height of the heat exchange components. (5) The heat dissipation unit of this utility model can be installed in the cabin by setting a new type of heat exchanger, which meets the miniaturization requirements of the heat dissipation unit inside the cabin. (6) The novel cabin of this utility model divides the internal space of the cabin into two spaces by a partition. The top space (i.e., the first space) can accommodate the novel heat exchanger, while the personnel activity space (i.e., the second space) is equipped with a heat dissipation host. Since the height requirement of the novel heat exchanger is low, the height of the first space is also reduced. Then, while keeping the overall internal space of the cabin constant, the height of the second space is increased, thereby increasing the personnel activity space and increasing the comfort of the personnel.

[0024] Example: The novel heat exchanger and the heat dissipation unit and novel compartment included therein, as described in the preferred embodiment of this utility model, are as follows: Figures 1-6 As shown, the novel heat exchanger 1 includes a fan 101 and a heat exchange component 102 corresponding to the fan 101. The fan 101 includes an air inlet 1012 and an air outlet 1013. The air inlet 1012 is located at the bottom of the fan 101, while the air outlet 1013 is located on either side wall of the fan 101. The heat exchange component 102 is provided corresponding to the air inlet 1012 of the fan 101. The heat exchange component 102 includes a fixed base and a heat exchange tube disposed on the fixed base. The fixed base is connected to the bottom of the fan 101, so that the heat exchange tube can be aligned with the air inlet 1012. One end of the heat exchange tube is the inlet end, which is used to receive the cooling medium, and the other end is the outlet end, which is used to discharge the cooling medium. This allows the air to come into contact with the heat exchange tube when it enters the fan 101, and then exchange heat with the cooling medium in the heat exchange tube.

[0025] Specifically, the fan 101 includes a fan housing 1011, a rotating shaft 1014, an impeller, and a drive motor 1015. The rotating shaft 1014 is disposed inside the fan housing 1011, and its two ends are rotatably connected to the fan housing 1011. The two ends of the rotating shaft 1014 are the driven end and the driving end, respectively. Its driving end is connected to the drive motor 1015 so that it rotates under the drive of the drive motor 1015. Correspondingly, the impeller is sleeved on the outer peripheral wall of the rotating shaft 1014, and the operation of the fan 101 is realized by the rotation of the rotating shaft 1014. Furthermore, the air inlet 1012 is located at the bottom of the fan housing 1011, and the air outlet 1013 is located on the side wall of the fan housing 1011. The air inlet 1012 and the air outlet 1013 are respectively arranged facing the outer peripheral wall of the rotating shaft 1014, so that when the fan 101 is performing gas conveying operation, the air comes into contact with the heat exchange tube, thereby realizing the heat exchange between the air and the cooling medium in the heat exchange tube.

[0026] Furthermore, a first through hole and a second through hole are respectively provided on the fan housing 1011, which are aligned with each other. The driven end of the rotating shaft 1014 passes through the first through hole, while the driving end passes through the second through hole. Both the driven end and the driving end are rotatably connected to the fan housing 1011 through bearings. More preferably, the drive motor 1015 is disposed on the side wall of the fan housing 1011. The drive motor 1015 includes a driving part and a movable part. The driving part is fixedly connected to the fan housing 1011, while the movable part is fixedly connected to the driving end.

[0027] Furthermore, the rotating shaft 1014 extends along a first direction, which is the axial direction of the rotating shaft 1014, making the rotating shaft 1014 a long shaft type. Correspondingly, the air inlet 1012 and the air outlet 1013 also extend along the first direction, so that the length of the air inlet 1012 and the air outlet 1013 in the first direction is the same as the length of the rotating shaft 1014, thereby achieving that the air inlet 1012 and the air outlet 1013 are respectively matched with the rotating shaft 1014.

[0028] In a preferred embodiment, the fan housing 1011 is a cuboid structure with a hollow interior for mounting the rotating shaft 1014. The fan housing 1011 has two mounting plates at both ends in the first direction for mounting the rotating shaft 1014. Between the two mounting plates, there is a bottom plate, a first plate with an air outlet 1013, and a second plate located away from the first plate. An air inlet 1012 is formed at the bottom of the fan housing 1011.

[0029] Furthermore, the heat exchange tube includes multiple heat exchange units arranged in series. Each heat exchange unit has a tubular structure to allow the cooling medium to pass through. More preferably, the heat exchange units are arranged at intervals along a first direction or a second direction, with the second direction perpendicular to the first direction, and both the first and second directions perpendicular to the height direction. Further explanation is needed, as the height of the heat exchange tube is related to the diameter of the heat exchange units and the number of rows of heat exchange units, but not to the length of the heat exchange units or the number of heat exchange units in the second direction. Therefore, increasing the length and number of heat exchange units in the second direction does not affect the overall height of the heat exchange assembly 102.

[0030] In a preferred embodiment, multiple heat exchange units are spaced apart along a second direction, and the heat exchange units extend along a first direction such that the length of the heat exchange units in the first direction is the same as the length of the rotating shaft 1014, allowing the air to form good contact with the heat exchange units before entering the air inlet 1012. Further, the heat exchange units can be arranged in two rows spaced apart in the height direction, with the projections of the first row and the second row of heat exchange units on the bottom surface of the fan housing 1011 staggered, and the projections of each heat exchange unit on the air inlet 1012 covering the air inlet 1012, thereby ensuring that the air entering the air inlet 1012 undergoes heat exchange and is cooled.

[0031] Furthermore, the heat exchange tube is fixedly connected to the fan 101 via a mounting base. The mounting base includes two end plates, which are respectively connected to both ends of the fan housing 1011 and are aligned. Multiple through holes are provided on the end plates to allow the heat exchange unit to pass through, thereby achieving a fixed connection between the heat exchange unit and the mounting base, and subsequently, a fixed connection between the heat exchange unit and the fan 101. More preferably, the end plate is an "L"-shaped plate structure, and its horizontal plate is fixedly connected to the fan housing 1011 by bolts.

[0032] Furthermore, with both ends of the heat exchange unit passing through the through holes in the end plates, the ends of the heat exchange units are located on the outer side of the end plates (i.e., the side of the end plate facing away from the other end plate), and adjacent heat exchange units are connected by bent pipes to achieve series connection between the heat exchange units. More preferably, as shown... Figure 1 , 2 As shown, in the two rows of heat exchange units spaced apart along the height direction, the bent pipes located on the outer side of one end plate are connected to two adjacent heat exchange units in the height direction, while the bent pipes located on the outer side of the other end plate are connected to two adjacent heat exchange units in the second direction, so that the cooling medium flow path of the heat exchange tubes is staggered vertically.

[0033] Furthermore, a connector is provided between the two end plates, with each end of the connector fixedly connected to one of the end plates. More preferably, two connectors are spaced apart along the second direction, with each end of the connector fixedly connected to the end of the end plate, so that the mounting base forms a duct structure, ensuring that all air entering the fan 101 passes through the heat exchange tubes located inside the mounting base. Additionally, heat dissipation fins are provided on the outer peripheral wall of the heat exchange unit to promote heat exchange between the heat exchange unit and the air.

[0034] Furthermore, a water receiving tray 103 is provided at the bottom of the heat exchange component 102 to receive condensate. A condensate outlet is provided on the side wall of the water receiving tray 103 to discharge condensate. A support column is provided on the bottom surface of the water receiving tray 103, and a screw hole is provided at the top of the support column. A support plate is also provided on the outer wall of the end plate, and a through hole is provided on the support plate. The support plate and the support column are connected by screws, so that the water receiving tray 103 is fixedly connected to the heat exchange component 102, thereby realizing the fixed connection of the fan 101, the heat exchange component 102 and the water receiving tray 103.

[0035] Furthermore, a guide pipe 104 is provided at the air outlet 1013 of the fan 101 to change the direction of the cold air discharged from the air outlet 1013.

[0036] In a preferred embodiment, the height of the fan housing 1011 is 40~45mm, while the heat exchange assembly 102 only needs to be provided with two rows of heat exchange units, and its height can be compressed to 10~15mm. The height of the water receiving tray 103 is only 10mm, and its overall height can be compressed to within 70mm, so that the required height of the heat exchanger is low, making it suitable for low-ceiling spaces.

[0037] Furthermore, this utility model also proposes a heat dissipation unit, which includes at least one novel heat exchanger 1 and a heat dissipation host 2. The heat dissipation host 2 is connected to the heat exchange component 102 through a cooling medium pipe. The cooling medium pipe is connected to the inlet end and outlet end of the heat exchange tube respectively to realize the flow of the cooling medium. The cooling medium enters the heat exchange tube from the heat dissipation host 2 to absorb ambient heat, and then flows back into the heat dissipation host 2 to release heat.

[0038] Furthermore, this utility model also proposes a novel cabin, including a heat dissipation unit and a cabin body 3. The cabin body 3 is internally equipped with a partition 4 to divide it into two spaces, a first space and a second space. A novel heat exchanger 1 is disposed in the first space, and correspondingly, a heat dissipation unit 2 is disposed in the second space. The partition 4 has through holes connecting the first and second spaces, allowing gas from the second space to enter the first space. A guide pipe 104, L-shaped, is disposed at the air outlet 1013, with one end connected to the air outlet 1013 and the other end connected to the second space to introduce cooled air into the second space, thereby enhancing cooling efficiency. More preferably, a grid 105 is disposed at the end of the guide pipe 104 furthest from the fan 101.

[0039] Furthermore, a heat exhaust pipe is provided corresponding to the heat dissipation host 2 to exhaust the waste heat released by the heat dissipation host 2 and prevent heat from accumulating inside the chamber 3. One end of the heat exhaust pipe is connected to the heat dissipation host 2, and the other end is connected to the outside of the chamber 3. A heat exhaust fan 101 is provided corresponding to the heat exhaust pipe to exhaust the hot air.

[0040] Furthermore, the new cabin is an oxygen chamber with a built-in oxygen supply device for daily use, and its interior is cooled by a cooling unit. More preferably, the new cabin can also be a safety cabin, with its body 3 possessing fireproof and heat-insulating capabilities. Smoke sensors or temperature sensors are installed on the outer wall of the body 3 so that, in the event of an emergency, the cooling unit can pre-cool the interior of the body 3. After personnel enter the body 3, and to ensure the body 3 is sealed inside and out, the cooling unit can be shut down, along with the corresponding heat exhaust pipes, to achieve pre-cooling of the interior of the body 3.

[0041] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
