Description

Technical Field

[0001] This utility model relates to the field of water chillers, and in particular to a structure for a small water chiller used in outdoor activities. Background Technology

[0002] A chiller unit (also known as a refrigeration unit, chiller, ice water unit, or cooling equipment) is a refrigeration device. Because chiller units are widely used across various industries, the requirements for them vary. In the refrigeration industry, they are divided into air-cooled and water-cooled chiller units, and based on the compressor, they are further classified as screw chiller units, scroll chiller units, centrifugal chiller units, etc.

[0003] In the existing technology, chillers used for outdoor activities (such as camping outdoors, where some food needs to be cooled to improve its taste) are often large and heavy due to the limitations of traditional structures, requiring multiple people to carry them. They use traditional liquid cooling circulation pipes and radiators, which are not only complex to manufacture but also further increase the weight. Air cooling systems use multiple fans for air cooling, which are not only noisy during operation but also affected by the surrounding airflow, resulting in poor cooling effect.

[0004] In view of this, this technical solution proposes a small chiller structure for outdoor activities, which uses a semiconductor cooling chip in conjunction with heat exchangers on both sides to form a micro-refrigeration cycle system inside the shell. It not only has a simple internal structure, light overall weight and low noise, but also has the characteristics of easy assembly and manufacturing, convenient use and easy portability. Utility Model Content

[0005] The present invention aims to at least partially solve one of the technical problems in the related art. Therefore, the main objective of this invention is to provide a small chiller structure for outdoor activities, addressing the problems of existing chiller equipment lacking portability, having poor cooling performance, and being noisy during operation.

[0006] To achieve the above objectives, this utility model provides a small chiller structure for outdoor activities, comprising a chiller body consisting of an outer casing and a refrigeration circulation assembly disposed within the outer casing.

[0007] The outer casing has water inlets and air outlets on its top and sides, respectively. The back of the outer casing has a water outlet and a water return outlet, and air inlets are located on both sides. A switch socket is located at the top.

One side of the radiator is connected to the water outlet, and the other side of the water tank is equipped with a condenser with a fan. One end of the condenser is connected to the other side of the radiator, and the other end of the condenser is connected to a semiconductor refrigeration chip equipped with a heat exchanger. The heat exchanger is also connected to the water outlet of the water tank. The fan, condenser and air outlet are positioned corresponding to each other.

[0009] As a further embodiment of this invention, the number of the fan and the condenser is at least two, and they are respectively connected to both sides of the semiconductor cooling chip and the radiator.

[0010] As a further embodiment of this utility model, the water outlet is connected to the water tank and the water inlet via a three-way connector.

[0011] As a further improvement of this utility model, the three-way connector is provided with a temperature sensor for sensing water temperature.

[0012] As a further improvement of this invention, a flow meter is also connected between the water tank and the heat exchanger.

[0013] As a further embodiment of this utility model, the outer shell is a laterally inverted triangular truncated cone structure, with a display screen on the top, handles on the top of the two sloping sides for easy handling, and rubber pads at the bottom to increase placement stability.

[0014] As a further embodiment of this utility model, the fan, condenser, heat exchanger and semiconductor cooling chip are connected and arranged in a configuration consistent with the outline of the apex of the triangular pyramid, and the radiator is located opposite the apex structure.

[0015] As a further embodiment of this utility model, the outer shell is an integrally bent plastic-coated aluminum shell structure.

[0016] The beneficial effects of this utility model are as follows:

It does not require complex multi-fan and heat exchange structures; it only uses a single cooling chip to connect the heat exchanger and condenser. The internal structure is simple, and when assembled in the casing, it has a light weight and small size, making it particularly suitable for portable outdoor use. Attached Figure Description

[0024] as follows:

[0025] Please see the appendix Figure 1-4 ,

[0026] The main structure includes a chiller body 1 consisting of an outer casing 10 and a refrigeration circulation assembly 11 disposed within the outer casing 10. The outer casing 10 has a water inlet 11 and an air outlet 14 on its top and sides, a water outlet 16 and a water return 17 on its back, and air inlets 18 on both sides. A switch socket 15 is also located at the top. The refrigeration circulation assembly 11 includes a water tank 110 connected to the water inlet 11 and the water return 17, and a... A radiator 116 is located on one side of the water tank 110. One side of the radiator 116 is connected to the water outlet 16. On the other side of the water tank 110, a condenser 1140 equipped with a fan 114 is provided. One end of the condenser 1140 is connected to the other side of the radiator 116, and the other end of the condenser 1140 is connected to a semiconductor cooling chip 1150 equipped with a heat exchanger 115. The heat exchanger 115 is also connected to the water outlet of the water tank 110. The fan 114, the condenser 1140 and the air outlet 14 are positioned correspondingly.

[0027] The working principle is as follows:

[0028] During operation, water is injected into the water tank 110 through the water inlet 11. After passing through the pump, the water in the water tank 110 flows through its outlet to a heat exchanger 115 equipped with a semiconductor cooling chip 1150 for cooling and heat exchange. Then, the cold water is discharged to an external water storage device through the radiator 116 and the outlet 16. When the water in the external water storage device approaches room temperature, it is returned to the water storage device through the return inlet 17. Specifically, water enters through the return inlet 17, flows to the water tank 110, and the water tank 110 sends the room temperature water back to the heat exchanger 115 for cooling and heat exchange. The cold water is then discharged to the external water storage device again through the radiator 116 and the outlet 16, and the cycle continues. The chiller's ability to circulate within a small volume is thanks to the combination of the semiconductor refrigeration chip 1150 and the heat exchanger 115. The semiconductor refrigeration chip is a thin-film refrigeration chip, which is compact in size and has high cooling efficiency. After being assembled with the heat exchanger 115, the thickness is relatively thin. Furthermore, the structure of connecting the condenser 1140 and the fan 114 on both sides avoids the bulkiness caused by the stacked structure.

[0029] The heat exchanger 115 in this solution adopts a semiconductor water flow channel heat exchanger, which allows the semiconductor cooling chip 1150 and the circulating water to exchange heat alternately, maximizing the heat exchange area, improving the heat exchange efficiency of the refrigeration system, reducing the volume of the heat exchanger 115, and having an actual power of 300W. It ensures full heat conversion and significantly improves the refrigeration efficiency of the system. At the same time, the internal structure of the equipment is compact, thus achieving the characteristics of small size, light weight, and sufficient cooling capacity.

[0030] In a preferred embodiment of this utility model, at least two fans 114 and condensers 1140 are provided, and are respectively connected to both sides of the semiconductor cooling chip 1150 and the radiator 116.

[0031] The fan 114 and condenser 1140, which adopt a double-blade structure, allow for more complete airflow for cooling, achieving rapid cooling.

[0032] In a preferred embodiment of this invention, the water outlet 16 is connected to the water tank 110 and the water inlet 11 via a T-joint 113. The T-joint 113 is equipped with a temperature sensor 112 for sensing the water temperature.

[0033] Various sensors can be installed on the tee connector 113, such as the temperature sensor 112 preferred in this scheme. Using the tee connector 113 can also further reduce the number of pipelines, further reduce the volume and weight.

[0034] In a preferred embodiment of this utility model, a flow meter 111 is also connected between the water tank 110 and the heat exchanger 115.

[0035] The flow meter 111 can be used in conjunction with the main controller and display screen 12 to monitor the water injection volume.

[0036] In a preferred embodiment of this invention, the outer casing 10 is a laterally inverted triangular pyramid structure, with a display screen 12 on the top, handles 13 on the top of the two sloping sides for easy handling, and rubber pads 19 on the bottom to increase placement stability. The fan 114, condenser 1140, heat exchanger 115, and semiconductor cooling chip 1150 are connected and arranged in a configuration consistent with the outline of the apex of the triangular pyramid, with the radiator 116 positioned opposite the apex.

[0037] The entire outer shell 10 has a triangular frustum structure and is inverted to one side, which ensures that a large area on the back can serve as an air inlet 18. The sloping exhaust surfaces on both sides (air outlets 14) have minimal impact on the airflow temperature and are also easy to move and carry.

[0038] In a preferred embodiment of this utility model, the outer shell 10 is an integrally bent plastic-coated aluminum shell structure.

[0039] The one-piece plastic-coated aluminum structure has high strength, is easy to process and manufacture, and is not easily damaged, making it particularly suitable for outdoor use, such as camping, exploration, rescue and scientific research activities.

[0040] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. Any equivalent structural transformations made using the contents of the present utility model specification and drawings under the concept of the present utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
