[0041] The utility model provides a door body component, aiming to provide a door body component which can reduce power consumption and avoid condensation on the door frame.

[0042] See also Figure 1 and Figure 2 In one embodiment of the present invention, the door assembly 100 is used for refrigeration equipment, and the door assembly 100 includes a door body 1 and a heat pipe 2. The door body 1 is used to cover the opening of the compartment, and the door body 1 includes a door panel 11 and a door frame 12 arranged around the door panel 11; the heat pipe 2 is installed on the door body 1, and the heat pipe 2 is connected to the refrigerant circulation pipeline of the refrigeration equipment.

[0043] It should be noted that the door assembly 100 is primarily composed of a door body 1 and a heat pipe 2. The door body 1 seals the opening of the compartment. The door panel 11 closes the opening. When the refrigeration equipment is a refrigerator or freezer, the door panel 11 is generally configured as a glass door. The door frame 12 surrounds the door panel 11, providing structural support and ensuring that the door panel 11 can effectively seal the opening. The heat pipe 2 is connected to the refrigerant circulation pipeline of the refrigeration equipment for transmitting refrigerant.

[0044] The heat pipe 2 is installed on the door body 1, and can be installed on the door frame 12, can be installed on the door panel 11, or can be sandwiched between the inner periphery of the door frame 12 and the outer periphery of the door body 1. The specific design can be based on actual conditions, and this specification does not limit this.

[0045] It can be understood that the door body assembly 100 is used for refrigeration equipment, and the door body 1 covers the opening of the compartment. Since the temperature inside the compartment is relatively low, when the external ambient temperature is relatively high, there is an obvious temperature difference between the inside and the outside. When the warm and humid air contacts the surface of the colder objects (such as the glass door of the refrigerator), the water vapor in the air will reach saturation on these colder surfaces and begin to condense into small water droplets. Then the outer surface of the door panel 11 will become a condensation point, forming the so-called "condensation".

[0046] It should be noted that the refrigerant gas cycle in the refrigeration system can be divided into four main stages: evaporation, compression, condensation, and expansion. During the evaporation stage, liquid refrigerant enters the evaporator and evaporates into a gas by absorbing heat from the surrounding environment. During this process, the refrigerant is at low pressure and low temperature. As the refrigerant absorbs heat, it changes from liquid to gas while maintaining a relatively constant temperature (i.e., the evaporation temperature). During the compression stage, the evaporated gaseous refrigerant is drawn into the compressor and compressed into a high-pressure, high-temperature gas. The refrigerant discharge temperature at the compressor can reach 70°C to 90°C or even higher. During the condensation stage, the high-temperature, high-pressure gaseous refrigerant releases heat to the external environment (usually air or water) in the condenser, condensing into a liquid. The condensing temperature at the condenser outlet can range from 30°C to 50°C. During the expansion stage, the liquid refrigerant rapidly depressurizes as it passes through the expansion device, causing some of the liquid to instantly vaporize (flash vaporization), resulting in a sharp drop in the mixture temperature.

[0047] Since the temperature of the refrigerant gas in each stage of the above-mentioned circulation process is different, the heat pipe 2 can be connected to the stage where the refrigerant temperature is higher, such as the compression stage and the condensation stage. Preferably, the heat pipe 2 is connected to the exhaust port of the compressor so that when the refrigerant temperature reaches the highest point, the heat is transferred to the door frame 12 through the heat pipe 2.

[0048] In the technical solution of the present invention, the door body assembly 100 includes a door body 1 and a heat conduction pipe 2, the door body 1 includes a door panel 11, and a door frame 12 arranged around the door panel 11, the heat conduction pipe 2 is installed on the door body 1, and the heat conduction pipe 2 is connected to the refrigerant circulation pipeline of the refrigeration equipment, and the high-temperature refrigerant gas in the refrigerant circulation pipeline is conducted, so that the high-temperature refrigerant can flow in the heat conduction pipe 2 along the circumference of the door body 1, so that the temperature of the door frame 12 can be increased to avoid the generation of condensation. By directly conducting the high-temperature refrigerant gas discharged from the compressor to the door frame 12 through the heat conduction pipe 2, there is no need to consume additional electricity to adopt electric heating, so as to provide a door body assembly 100 that can reduce power consumption while avoiding condensation on the door frame 12.

[0049] For further information, please refer to Figure 1 and Figure 2In this embodiment, the heat pipe 2 is arranged to extend along the circumference of the door frame 12. In this way, the heat pipe 2 is installed on the door frame 12, so that the heat of the heat pipe 2 can be quickly transferred to the door frame 12, thereby improving the anti-condensation efficiency of the door frame 12.

[0050] The heat pipes 2 are arranged along the circumference of the door frame 12 (i.e., the edge of the door frame 12), rather than being concentrated in a certain area or arranged in a straight line. This ensures that the heat pipes 2 can function throughout the entire periphery of the door body 1, thereby achieving a uniform heat conduction effect. The contact area between the heat pipes 2 and the door frame 12 is also increased, thereby improving the anti-condensation efficiency.

[0051] It should be noted that the heat pipe 2 extends along the circumference of the door frame 12, which does not mean that the heat pipe 2 must be bent and wrapped around the door frame 12 in a straight line. The heat pipe 2 can also be S-shaped or Z-shaped, but the overall extension direction can be extended along the circumference of the door frame 12. In this way, more areas can be covered on the width of the door frame 12, and the heat exchange area can also be increased.

[0052] Of course, in addition to increasing the heat exchange area in the above-mentioned manner, the diameter of the heat pipe 2 can also be increased, or the cross-section of the heat pipe 2 can be made into a square tube. Of course, other possible shapes can also be used. The specific shape can be determined according to actual conditions, and the embodiments of this specification do not limit this.

[0053] Further, see Figure 3 and Figure 4 In this embodiment, a limiting groove 12a extending along the circumference of the door frame 12 is opened on the door frame 12; the heat pipe 2 is installed in the limiting groove 12a.

[0054] The limiting groove 12a extends circumferentially and conforms to the contour of the door frame 12, providing a fixed installation position for the heat pipe 2. The limiting groove 12a restricts and secures the position of the heat pipe 2, ensuring that the heat pipe 2 is securely installed within the door frame 12 and preventing it from shifting or loosening during use.

[0055] It is understandable that the limiting groove 12a and the heat conducting pipe 2 can be set to a transition fit or an interference fit, so that the heat conducting pipe 2 can be properly embedded in the limiting groove 12a to form a tight combination.

[0056] By providing the limiting groove 12a on the door frame 12, the installation process of the heat pipe 2 can be simplified, making the installation more convenient and accurate. The limiting groove 12a ensures that the position of the heat pipe 2 on the door frame 12 is optimized, thereby improving the efficiency of heat conduction and ensuring uniformity of the heat conduction effect.

[0057] For further information, please refer to Figure 3 and Figure 4 In this embodiment, the door frame 12 is provided with a mounting channel 12b extending along the circumference of the door frame 12, and a through hole 12c connected to the mounting channel 12b, and the limiting groove 12a is formed on the inner wall of the mounting channel 12b; both ends of the heat pipe 2 extend outward from the through hole 12c.

[0058] The installation channel 12b extends along the periphery of the door frame 12, and the limiting groove 12a is formed on the inner wall of the installation channel 12b. The installation channel 12b is used to accommodate the installation of the heat pipe 2, ensuring that it can be smoothly arranged around the door frame 12. The through hole 12c is connected to the installation channel 12b, allowing the end of the heat pipe 2 to extend from the inside to the outside, conveniently connecting to external equipment or pipelines, ensuring the functionality of the heat pipe 2 and effectively transmitting refrigerant or heat. At the same time, when the heat pipe 2 needs to be replaced or repaired, there is no need to disassemble the entire door frame 12 structure, thereby facilitating the installation, function realization, and maintenance of the heat pipe 2.

[0059] Furthermore, when the door frame 12 is installed, it is mounted on the housing of the refrigerator through a rotating shaft hinge. In order to avoid the interference friction between the heat pipe 2 and the periphery of the through hole 12c and other components during the rotation process, so that the heat pipe 2 is worn and leaks, please continue to refer to Figure 3 and Figure 4 In this embodiment, the door frame 12 includes a plurality of frames 121 connected in sequence, and the plurality of frames include a first frame 1211 for rotationally connecting with the box body, and the end of the first frame 1211 is provided with the through hole 12c; the door body assembly 100 also includes a sleeve 3 installed in the through hole 12c, and the sleeve 3 is sleeved on the periphery of the two ends of the heat pipe 2.

[0060] It should be noted that when the door frame 12 is installed, the rotation axis generally extends along the length of the door frame 12. Accordingly, the through hole 12c is provided at one end of the first side frame 1211 in the length direction, preferably coaxially with the rotation axis. Therefore, when the door body 1 rotates, the two ends of the heat pipe 2 will not undergo significant relative displacement relative to the door frame 12 and the refrigerator housing. This also reduces the possibility of wear on the heat pipe 2.

[0061] By placing the sleeve 3 within the through hole 12c and surrounding the two ends of the heat pipe 2, the inner diameter of the sleeve 3 matches the outer diameter of the heat pipe 2, ensuring a perfect fit. This arrangement not only enhances the fixation of the heat pipe 2, but also provides good support for the ends of the heat pipe 2, enhancing the stability and durability of the overall structure.

[0062] Furthermore, in order to make the best use of the heat of the heat pipe 2, please refer to Figure 3 and Figure 4 In this embodiment, the heat pipe 2 is arranged close to the inner periphery of the door frame 12 .

[0063] It should be noted that, when the heat pipe 2 is close to the inner periphery of the door frame 12, that is, the position of the door frame 12 close to the outer periphery of the door panel 11, the heat pipe 2 can not only prevent condensation at the door frame 12, but also transfer heat as much as possible to the door panel 11 where condensation is more likely to occur, and at the same time, it can also conduct heat to the outer periphery of the door panel 11.

[0064] For further information, please refer to Figure 3 and Figure 4 In this embodiment, the door body 1 has an inner side and an outer side that are arranged opposite to each other, and the inner side of the door body 1 is used to be arranged toward the compartment; the heat pipe 2 is arranged close to the outer side of the door frame 12.

[0065] It should be noted that, because the door body 1 is covered on the opening of the compartment, the outer side of the door body 1 is in direct contact with the outside air, and when the temperature is low, condensation condenses on the outer side of the door body 1. In this way, when the heat pipe 2 is arranged on the outer side close to the door frame 12, the heat of the heat pipe 2 can be better transferred to the outer part of the door body 1, while affecting the temperature close to the compartment as little as possible.

[0066] The present invention also proposes a refrigeration device, which includes a box body, a refrigeration system and a door body assembly 100, wherein the box body has a compartment with an opening on one side; the refrigeration system includes a refrigerant circulation pipeline, the door body assembly 100 is covered on the opening, and the heat pipe 2 is connected to the refrigerant circulation pipeline. The specific structure of the door body assembly 100 refers to the above embodiment. Since this refrigeration device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0067] It is understandable that the refrigeration system generally includes the following important components: compressor, condenser, evaporator, refrigerant, etc. The compressor is the heart of the refrigeration system, responsible for compressing the refrigerant, increasing its pressure and temperature, and sending it to the condenser. The condenser cools the high-temperature and high-pressure gaseous refrigerant and condenses it into a liquid. The heat is discharged through air or water cooling. The evaporator is the cooling component of the refrigeration system, where the low-pressure liquid refrigerant absorbs the surrounding heat, evaporates into a gaseous state, and takes away heat from the environment, thereby achieving a cooling effect. The refrigerant is a circulating working medium responsible for transferring heat in the refrigeration system. The refrigerant constantly changes its state (gaseous and liquid) between different components. These components work together to form a complete refrigeration cycle, realizing the functions of refrigeration and heat transfer.

[0068] Specifically, in this embodiment, the refrigeration system includes a compressor and a condenser, the compressor is provided with an exhaust port; the condenser is provided with an air inlet; wherein one end of the heat pipe 2 is connected to the exhaust port, and the other end is connected to the air inlet.

[0069] In the foregoing, it has been explained that the temperature of the refrigerant gas in each stage of the above-mentioned cycle process is not the same. Because in the compression stage, the exhaust temperature of the compressor is as high as 70°C or above, the heat pipe 2 is connected to the exhaust port of the compressor so that when the refrigerant temperature reaches the highest point, the heat is transferred to the door frame 12 through the heat pipe 2, so that the thermal energy is optimized and the anti-condensation effect is optimized.

[0070] Specifically, in this embodiment, the refrigeration equipment includes a medical refrigerator or a refrigerator.

[0071] A medical refrigerator is a refrigeration device specially designed to store and protect medical items, medicines, vaccines, biological samples, etc., ensuring that critical items are kept at the appropriate temperature.

[0072] The refrigerator is used to store and preserve food, beverages and other items. Of course, the refrigeration equipment is not limited to including the medical refrigerator or refrigerator, and can also be a freezer, or a display cabinet, etc., which will not be described in detail here.

[0073] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
