Description

Technical Field

[0001] The utility model relates to the technical field of refrigerating machine heat dissipation, in particular to a refrigerator heat dissipation device. Background Technique

[0002] A refrigerating machine is a device used for refrigeration or cooling, usually used in industrial, commercial and household applications. The application of refrigerating machines is very extensive, including household refrigerators, commercial refrigerated cabinets, air conditioning systems, cold storage warehouses, chemical processes, medical equipment and other fields. Currently, household refrigerators are one of the most extensive fields in the popular application of refrigerating machines. In some ice cream wholesale markets, in order to delay the melting speed of ice cream, refrigerators are usually placed in a relatively unventilated indoor environment, or an environment with only a single ventilation door and no windows. The heat dissipation of existing refrigerators is usually from both sides of the refrigerator. In a high-temperature environment in summer, due to the large amount of heat dissipation air volume discharged from the air inlet end of the heat dissipation plates on both sides of the refrigerator, it may cause the surrounding air temperature to rise, resulting in poor indoor air circulation, increasing the discomfort of users, and may exacerbate the heat feeling indoors. Especially in an enclosed space or a space with poor ventilation, this situation may be more obvious.

[0003] The implementation of the utility model aims to provide a refrigerator heat dissipation device to solve the problems put forward in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art put forward in the background technique, and to propose a refrigerator heat dissipation device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A refrigerator heat dissipation device is arranged inside the refrigerator main body, including a heat dissipation mechanism and a guide air pipe. A heat dissipation fan is arranged inside the heat dissipation mechanism, and an air inlet is penetrated through the surface of the heat dissipation mechanism. A plurality of air inlets are provided on the surface of the heat dissipation mechanism, and the plurality of air inlets are symmetrically arranged on both sides of the surface of the heat dissipation mechanism.

[0007] Preferably, a ventilation groove is arranged on the other side of the air inlet, and a connection groove is penetrated through the other side of the ventilation groove. The other side of the connection groove is fixedly connected with the air inlet end of the heat dissipation plate.

[0008] Preferably, a protection plate is fixedly connected to one side of the heat dissipation fan, and an air outlet is penetrated through the other side of the protection plate. The other end of the air outlet is penetrated with a shunt air pipe, and the other end of the shunt air pipe is connected with the guide air pipe.

[0009] Preferably, two groups of heat dissipation mechanisms are provided, and fixing grooves are fixedly connected to the surfaces of the two groups of heat dissipation mechanisms.

[0010] Preferably, the ventilation slot is integrally composed of upper and lower parts, and the two parts of the ventilation slot respectively correspond to a set of heat dissipation mechanisms.

[0011] Preferably, both parts of the ventilation slot are in an inverted U shape, and the U can be regarded as three mutually connected rectangles.

[0012] Preferably, a compressor is provided at the lower end inside the refrigerator main body, a condenser is connected to the upper end of the compressor, and a refrigerator is provided outside the condenser.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, by providing a gas guide pipe and a shunt gas pipe, when the heat dissipation mechanism of the device operates, the gas guide pipe can lead cold air from the refrigerator to the outside of the heat dissipation fan. When the heat dissipation fan rotates, the heat dissipation fan will dissipate heat and cool the inside of the device by blowing the air mixed with cold air, thereby improving the heat dissipation efficiency of the device. At the same time, the temperature of the air discharged from the heat dissipation plate is also reduced. Even in a poorly ventilated or small room, the device can reduce the heat sensation inside the room and avoid the discomfort caused by the influence of high-temperature hot air when the user approaches the refrigerator.

[0015] 2. By providing a ventilation slot and a connection slot, the air circulation space between the air inlet end of the heat dissipation plate and the heat dissipation fan becomes an air circulation channel. When the heat dissipation fan operates, it can accelerate the air circulation speed, thereby guiding the air flow at the air inlet end of the heat dissipation plate towards the inside of the refrigerator main body, effectively guiding the introduced cold air, and avoiding the waste of cold air caused by the cold air flowing towards one side of the air inlet end of the heat dissipation plate.

[0027] Embodiment

[0028] Refer to Figures 1-6, A refrigerator heat dissipation device is arranged inside the refrigerator main body 1, including a heat dissipation mechanism 6 and a gas guide pipe 7. The refrigerator main body 1 includes a refrigerating chamber and a freezing chamber inside the refrigerator, and a door is provided on the outer sides of the refrigerating chamber and the freezing chamber. At the same time, a compressor 5 is provided at the lower end inside the refrigerator main body 1, and a condenser 3 is connected to the upper end of the compressor 5. A cooler 4 is provided outside the condenser 3. When the device performs refrigeration operations, usually the compressor 5 compresses the refrigerant into a high-pressure gas, and then the condenser 3 dissipates heat and cools the refrigerant through a metal pipe in contact with the surrounding environment, so it becomes a liquid. Then, after the refrigerant enters the cooler 4, it absorbs the heat in the air by contacting the surrounding air and evaporates into a gaseous state. During this process, the temperature inside the cooler 4 will drop significantly, thereby achieving the refrigeration effect.

[0029] A heat dissipation mechanism 6 is provided inside the refrigerator main body 1, and a gas guide pipe 7 penetrates through the surface of the heat dissipation mechanism 6. One end of the gas guide pipe 7 is connected to the cooler 4 in a through manner, and the other end is connected to a shunt gas pipe 13 in a through manner. A throttle valve is provided inside the gas guide pipe 7. The throttle valve can limit the amount of cold air flowing from the cooler 4 into the gas guide pipe 7, avoiding the overall cooling effect of the device being affected by too much cold air flowing from the cooler 4 into the gas guide pipe 7. A heat dissipation fan 10 is provided inside the heat dissipation mechanism 6, and an air inlet 8 penetrates through the surface of the heat dissipation mechanism 6. A plurality of air inlets 8 are provided on the surface of the heat dissipation mechanism 6, and the plurality of air inlets 8 are symmetrically arranged on both sides of the surface of the heat dissipation mechanism 6. The other side of the air inlet 8 is provided with a ventilation groove 14, and the other side of the ventilation groove 14 penetrates through a connection groove 15. The other side of the connection groove 15 is fixedly connected to the air inlet end 2 of the heat dissipation plate. Through this setting, the air entering through the air inlet end 2 of the heat dissipation plate can be introduced into the air inlet 8 through the connection groove 15, and then the air inlet 8 can more evenly introduce the air to both sides of the heat dissipation fan 10, avoiding the reduction of the working efficiency of the heat dissipation fan 10 caused by a large difference in the air intake on both sides during the operation of the heat dissipation fan 10.

[0030] A protection plate 12 is fixedly connected to one side of the heat dissipation fan 10, and an air outlet 11 penetrates through the other side of the protection plate 12. The other end of the air outlet 11 penetrates through a shunt gas pipe 13, and the other end of the shunt gas pipe 13 is connected to the gas guide pipe 7. Through this design, the cold air output through the gas guide pipe 7 can be shunted into each heat dissipation fan 10 through the shunt gas pipe 13. A small motor is provided inside the heat dissipation fan 10. When the heat dissipation fan 10 rotates, the cold air input from the air outlet 11 can reduce the temperature of the air output by the heat dissipation fan 10, enabling the device to reduce the temperature of the condenser 3 inside the refrigerator main body 1 through a lower temperature gas.

[0031] There are two sets of heat dissipation mechanisms 6 in total. Fixed slots 9 are fixedly connected to the surfaces of the two sets of heat dissipation mechanisms 6. The ventilation slot 14 is composed of two upper and lower parts as a whole, and the two parts of the ventilation slot 14 respectively correspond to one set of heat dissipation mechanisms 6. Both parts of the ventilation slot 14 are in an inverted U shape, and the U can be regarded as three interconnected rectangles. The side of the ventilation slot 14 close to the connection slot 15 is a single hollow rectangular slot, and both sides of the rectangular slot are of an open design. One side of the two openings is connected to the connection slot 15 in a through manner, and the other side is connected to the two open rectangles of the other part. When the ventilation slot 14 is installed, it can be inserted into the inner side of the fixed slot 9, which simplifies the installation process. At the same time, the insertion design of the ventilation slot 14 also enhances the sealing performance between the ventilation slot 14 and the fixed slot 9.

[0032] Working principle: When the heat dissipation fan 10 inside the heat dissipation mechanism 6 of the present device is running, the air duct 7 can export the cold air from the cooler 4 to the outside of the heat dissipation fan 10. When the heat dissipation fan 10 rotates, it will dissipate heat and cool down the inside of the device by blowing the air mixed with cold air. At the same time, through the ventilation slot 14 and the connection slot 15, the air circulation space between the air inlet end 2 of the heat dissipation plate and the heat dissipation fan 10 becomes an air circulation channel. When the heat dissipation fan 10 is running, it can accelerate the air circulation speed, so as to direct the air flow at the air inlet end 2 of the heat dissipation plate towards the inside of the refrigerator main body, effectively guide the introduced cold air, and avoid the cold air flowing towards one side of the air inlet end 2 of the heat dissipation plate. At the same time, the air entering through the air inlet end 2 of the heat dissipation plate can be introduced into the air inlet 8 through the connection slot 15. Subsequently, the air inlet 8 can introduce the air more evenly into both sides of the heat dissipation fan 10, avoiding the reduction of the working efficiency of the heat dissipation fan 10 caused by the large difference in the air intake on both sides during the operation of the heat dissipation fan 10.

Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and shall all be included in the protection scope of the present invention.

[0034] In the description of the present invention, it should be understood that the terms indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
