Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, specifically a heat dissipation structure for a luggage refrigerator. Background Technology

[0002] Chinese Patent Application No. CN202411523098.9 discloses a lightweight refrigerator for outdoor use, with its refrigeration components housed within a cavity, including an evaporator, compressor, condenser, and cooling fan. The cavity is located within a bottom shell, with an air inlet and outlet on the bottom surface. Corresponding to the air inlet and outlet on the bottom surface of the outer skin layer, air inlets and outlets are also located on the bottom surface of the outer skin layer. During refrigeration, the cooling fan dissipates heat from the condenser. Outside air enters the cavity through the air inlets in the outer skin layer and the bottom shell, is driven by the cooling fan to pass through the compressor and condenser, and then exits the cavity through the air outlets in the bottom shell and the outer skin layer, thus achieving heat dissipation for the compressor and condenser. However, since the air inlets / outlets on the outer skin, bottom shell, and outer skin are all located at the bottom, dust and foreign objects on the ground can easily be drawn into the housing cavity through the air inlets on the outer skin and bottom shell. This results in a large amount of dust and foreign objects adhering to the inside of the housing cavity and the surface of the cooling components. At the same time, the air exhausted through the air outlets on the bottom shell and outer skin blows up the dust and foreign objects on the ground, causing them to fly around and affecting the user experience. Therefore, further improvements are necessary. Utility Model Content

[0003] The present invention aims to provide a heat dissipation structure for a bag refrigerator to overcome the shortcomings of the prior art.

[0004] A heat dissipation structure for a bag refrigerator designed for this purpose includes a bag and a refrigerator body housed inside the bag. The refrigerator body has an inner liner and an electrical cavity. The electrical cavity has an electrical cavity opening on its side and contains electrical components. The electrical components include at least a cooling fan. A side air vent is provided on the electrical cavity opening. The side of the bag corresponds to the electrical cavity opening, and the side air vent has a bag side opening. A cover is provided on the side air vent, and an air inlet and an air outlet are separated by the cover. A baffle is provided on the cooling fan. The air inlet of the cooling fan is connected to the air inlet through the baffle, and the air outlet of the cooling fan faces the electrical cavity, which is connected to the air outlet.

[0005] The side air vent is provided with a number of air holes. The cover plate is located inside the electrical cavity and covers some of the air holes. The air holes covered by the cover plate form the air inlets, and the air holes not covered by the cover plate form the air outlets.

[0006] The electrical cavity is divided into a flow guiding area and an air outlet area by the flow divider plate. The end of the cover plate is provided with an opening, and an end air outlet is formed between the opening and the side air plate. The end air outlet is connected to the flow guiding area, and the air outlet hole is connected to the air outlet area.

[0007] The electrical cavity or the flow divider is provided with a flow guiding section corresponding to the flow guiding area.

[0008] The diverter plate and the cover plate have a receiving part, and they are connected end to end through the receiving part.

[0009] The flow divider plate and the cover plate are fitted at a certain angle.

[0010] The flow divider is fixed inside the electrical cavity on one side and has a flow divider opening. The cooling fan is fixedly mounted on the flow divider opening, with the air inlet of the cooling fan facing the flow guide area and the air outlet of the cooling fan facing the air outlet area.

[0011] The electrical components also include an evaporator, a condenser, and a compressor. The evaporator is in contact with the inner liner. The condenser is located in front of the air outlet of the cooling fan. The two ends of the condenser are respectively connected to one end of the evaporator and the output end of the compressor. The compressor is located between the condenser and the air outlet, and its input end is connected to the other end of the evaporator.

[0012] The refrigerator body is also provided with a cover plate, which opens and closes the inner liner.

[0013] The bag is also equipped with a carrying strap.

[0014] This utility model, through structural improvements, provides an electrical cavity opening on the side of the electrical cavity, and a side air vent on the opening. A cover plate is also provided on the side air vent, dividing it into an air inlet and an air outlet. This ensures that the air inlet and outlet are located on the same side of the refrigerator body, avoiding the problem of multiple air vents at different locations on the bag / refrigerator body, which would result in poor overall appearance. Furthermore, because the air inlet and outlet are side-mounted, air is only drawn in and expelled from the side of the bag / refrigerator body, effectively preventing dust and foreign objects from being drawn into the electrical cavity or blown outwards, thus improving the user experience. Additionally, a diverter plate is provided on the cooling fan. This diverter plate allows the cooling fan to draw external air into the electrical cavity through the air inlet, dissipating heat from the electrical components, and then expelling the air from inside the electrical cavity through the air outlet. This more orderly airflow improves the heat dissipation effect of the electrical components, making it highly practical. Attached Figure Description

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] See Figures 1-3 The heat dissipation structure of this bag refrigerator includes a bag 1 and a refrigerator body 2 housed inside the bag 1. The refrigerator body 2 has an inner liner 3 and an electrical cavity 4. The electrical cavity 4 has an electrical cavity opening 5 on its side and contains electrical components. The electrical components include at least a cooling fan 6. A side air plate 8 is provided on the electrical cavity opening 5. The side of the bag 1 has a bag side opening 7 corresponding to the electrical cavity opening 5 and the side air plate 8. A cover plate 9 is provided on the side air plate 8, and an air inlet 10 and an air outlet 11 are separated by the cover plate 9. A diverter plate 12 is provided on the cooling fan 6. The air inlet end of the cooling fan 6 is connected to the air inlet 10 through the diverter plate 12. The air outlet end of the cooling fan 6 faces the electrical cavity 4, and the electrical cavity 4 is connected to the air outlet 11.

[0021] In this embodiment, an electrical cavity opening 5 is provided on the side of the electrical cavity 4, and a side air vent 8 is provided on the electrical cavity opening 5. A cover plate 9 is also provided on the side air vent 8, dividing the side air vent 8 into an air inlet 10 and an air outlet 11. This ensures that the air inlet 10 and air outlet 11 are located on the same side of the refrigerator body 2. This not only avoids the problem of having multiple air vents at different locations on the bag 1 and the refrigerator body 2, resulting in poor overall appearance of the bag 1 and the refrigerator body 2, but also ensures that air only enters from the side of the bag 1 and the refrigerator body 2, since the air inlet 10 and air outlet 11 are located on the side. The air intake and exhaust system effectively prevents the refrigerator from sucking dust and foreign objects from the placement area into the electrical cavity 4 and blowing them outwards, thus improving the user experience. In addition, the cooling fan 6 is equipped with a diverter plate 12. By utilizing the diverter plate 12, the cooling fan 6 can draw external air into the electrical cavity 4 through the air inlet 10 to dissipate heat from the electrical components, and finally exhaust the air inside the electrical cavity 4 through the air outlet 11. This makes the airflow more orderly and improves the heat dissipation effect of the electrical components, making it highly practical.

[0022] The side air panel 8 is provided with several air holes. The cover plate 9 is located inside the electrical cavity 4 and covers some of the air holes. The air holes covered by the cover plate 9 form air inlets 10, and the air holes not covered by the cover plate 9 form air outlets 11.

[0023] In this embodiment, the side air plate 8 is fixed to the electrical cavity opening 5 by fasteners and has a number of air holes spaced apart. The cover plate 9 is fixed to the back of the side air plate 8 by fasteners and covers some of the air holes, so that the air holes covered by the cover plate 9 form air inlets 10 and the air holes not covered by the cover plate 9 form air outlets 11.

[0024] The electrical cavity 4 is divided into a flow guide area A and an air outlet area B by a flow divider plate 12. The end of the cover plate 9 is provided with an opening 13, and an end air outlet 14 is formed between the opening 13 and the side air plate 8. The end air outlet 14 is connected to the flow guide area A, and the air outlet 11 is connected to the air outlet area B.

[0025] In this embodiment, an air flow channel is formed between the cover plate 9 and the side air plate 8. The air flow channel is connected to the guide zone A through the end air outlet 14, so that air enters the air flow channel through the air inlet 10 and then enters the guide zone A through the end air outlet 14. In addition, the air located in the air outlet zone B is discharged through the air outlet 11.

[0026] The electrical cavity 4 or the diverter plate 12 is provided with a diverter section 15 corresponding to the diverter zone A.

[0027] In this embodiment, the airflow guide 15 is arc-shaped and disposed on the inner wall of the electrical cavity 4. The air in the airflow channel is guided into the airflow guide area A through the airflow guide 15 to improve the airflow.

[0028] There is a receiving part 16 between the diverter plate 12 and the cover plate 9, and they are connected end to end through the receiving part 16.

[0029] The manifold 12 and the cover plate 9 are fitted at a certain angle.

[0030] In this embodiment, the receiving part 16 is provided at the end of the diverter plate 12, and the cover plate 9 is supported on the receiving part 16 and the two are perpendicularly matched, thereby ensuring that the air in the air flow channel can enter the guide zone A.

[0031] The diversion plate 12 is fixed inside the electrical cavity 4 on one side and has a diversion opening 17. The cooling fan 6 is fixed on the diversion opening 17. The air inlet of the cooling fan 6 faces the diversion area A and the air outlet of the cooling fan 6 faces the air outlet area B.

[0032] In this embodiment, the cooling fan 6 is vertically fixed on the diversion opening 17. When the cooling fan 6 is working, its air inlet end draws the air in the guide zone A into the air outlet zone B.

[0033] The electrical components also include an evaporator, a condenser 18, and a compressor 19. The evaporator is in contact with the inner liner 3. The condenser 18 is located in front of the air outlet of the cooling fan 6. The two ends of the condenser 18 are connected to one end of the evaporator and the output end of the compressor 19, respectively. The compressor 19 is located between the condenser 18 and the air outlet 11, and its input end is connected to the other end of the evaporator.

[0034] In this embodiment, the evaporator, condenser 18 and compressor 19 are all located in the air outlet zone B. The air drawn into the air outlet zone B by the cooling fan 6 can dissipate heat from the evaporator, condenser 18 and compressor 19, and the dissipated air is discharged through the air outlet 11.

[0035] Among them, the direction of air flow is as follows Figure 2 As indicated by the arrow.

[0036] The refrigerator body 2 is also equipped with a cover 20, which opens and closes inside the inner liner 3, so that users can easily take out and put in items that need to be refrigerated inside the inner liner 3.

[0037] The bag 1 is also equipped with a shoulder strap 21, which allows the user to carry the refrigerator body 2 on their back, making it convenient to use.
