Description

Technical Field

[0001] This utility model belongs to the field of refrigeration unit technology, specifically relating to wire tube integrated refrigeration unit. Background Technology

[0002] The operation of refrigeration equipment relies on refrigeration units. In order to ensure that the refrigeration equipment can cool down quickly, maintain a constant temperature, and work efficiently and energy-savingly, the structure and system of the refrigeration unit need to be designed.

[0003] In the design of traditional wire-tube refrigeration units, the condensate inlet and outlet pipes are often located in different positions within the unit. This not only increases the complexity of piping connections but may also lead to spatial conflicts and an increased error rate during installation. Furthermore, the arrangement of the condensate pipes directly affects the distribution and collection efficiency of the condensate, thereby impacting the overall performance of the condensation system and equipment maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a wire-tube integrated refrigeration unit to solve the problems of condenser tube arrangement and heat dissipation in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wire-tube integrated refrigeration unit includes a base on which a compressor, an evaporator, and a condenser are mounted. The condenser includes a heat dissipation shell with side wing sheet metal on both sides. Several openings are penetrated through the surface of the side wing sheet metal, and condenser tubes are installed on the openings.

[0007] The condenser tube has a condenser inlet pipe and a condenser outlet pipe distributed at its upper and lower ends, and a collection device is connected to the condenser inlet pipe and the condenser outlet pipe.

[0008] Furthermore, the evaporator is located in the Y-axis direction of the compressor, and the condenser is located in the X-axis direction of the compressor; the condenser tubes inside the condenser are filled with refrigerant.

[0009] Furthermore, the openings are staggered and equidistant. The openings are arranged in a group with the front and back staggered, and then arranged equidistantly in sequence; at the same time, each group of openings is distributed upwards at equal intervals. The staggered arrangement allows the airflow or cooling medium to flow more smoothly through the condenser tube, thereby improving heat dissipation efficiency and ensuring that the heat inside the condenser tube can be quickly removed; the openings and the condenser tubes inside can be installed more compactly in a limited space, improving space utilization.

[0010] Furthermore, independent condenser tubes are installed on the staggered openings, and the condenser tubes are installed in a serpentine pattern inside the openings. On the same row of openings, the condenser tubes are laid out in a serpentine pattern from the uppermost opening to the lowermost opening, so that the condenser tubes are fully distributed inside the condenser.

[0011] Furthermore, both the condensate inlet pipe and the condensate outlet pipe extend to the same side wing sheet metal, with the condensate inlet pipe on top and the condensate outlet pipe on the bottom. The condensate inlet pipe and the condensate outlet pipe are bent perpendicularly to each other, and the bent parts of the condensate inlet pipe and the condensate outlet pipe are inserted into the collecting device.

[0012] Furthermore, the collection device includes a liquid collection tube and a drainage tube, with each independent condenser tube inserted into the liquid collection tube at equal intervals, and the drainage tube connecting to the inside of the liquid collection tube.

[0013] Furthermore, heat dissipation cores are equidistantly distributed on both sides of the condenser tube. These heat dissipation cores increase the heat exchange area between the condenser tube and the surrounding environment, thereby improving condensation efficiency.

[0014] Furthermore, the heat dissipation core has a cylindrical structure.

[0015] Furthermore, the heat sink is made of metal materials, preferably iron, copper, and aluminum. The specific materials used will be chosen based on the customer's actual usage requirements.

[0016] Furthermore, a rear sheet metal is installed behind the heat dissipation shell, a mesh frame is installed on the rear sheet metal, and a variable speed condenser fan is installed on the mesh frame.

[0017] The technical solution of this utility model has the following beneficial effects:

[0018] 1. Both the condensate inlet and outlet pipes are designed on the same side wing sheet metal, which greatly simplifies the layout of the condensation system. This design makes pipe connections more intuitive and convenient, reducing the complexity and error rate during installation.

[0019] 2. Each condenser tube is inserted into the collection tube at equal intervals, ensuring that the condensate is evenly distributed in the collection tube and avoiding uneven distribution caused by condensate accumulation in a certain area. The equidistant insertion of the condenser tubes and the connected drainage pipe make the maintenance and cleaning of the entire condensation system easier. It improves condensation efficiency and ensures that the condensate can be collected quickly and effectively. At the same time, the drainage pipe can evenly transport the condensate into each condenser tube, improving the circulation of the condensate in the condenser tubes.

[0020] 3. The cylindrical heat sink is in close contact with the outer wall of the condenser tube, effectively increasing the heat exchange area and promoting uniform heat distribution. This avoids localized overheating or uneven cooling, allowing heat from the condenser tube to be transferred to the surrounding environment more quickly. Compared to finned heat dissipation methods, the cylindrical heat sink significantly reduces dust accumulation on the condenser, and reduced dust improves the overall heat dissipation performance of the condenser.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] Example 1:

[0032] For ease of location description, the X-axis and Y-axis coordinates in the figure are used for generalization.

[0033] refer to Figures 1-4A wire tube type integrated refrigeration unit includes a base 10, on which a compressor 11, an evaporator 12 and a condenser 20 are installed. The condenser 20 includes a heat dissipation shell 201, and the heat dissipation shell 201 has side wing sheet metal 21 on both sides. Several openings 202 are penetrating the surface of the side wing sheet metal 21, and condenser pipes 203 are installed on the openings 202.

[0034] With compressor 11 as a reference position, evaporator 12 is located in the Y-axis direction of compressor 11, and condenser 20 is located in the X-axis direction of compressor 11; the condenser tube 203 inside condenser 20 is filled with refrigerant.

[0035] Compressor 11 compresses the refrigerant, raising its temperature to approximately 80–100°C and its pressure to 15–30 bar. The high-temperature, high-pressure gas then enters condenser 20. In condenser 20, the high-temperature gas exchanges heat with the outside air (or water), gradually cooling into a high-pressure liquid (phase change releases heat). Through a throttling device (such as an expansion valve), the high-pressure liquid is depressurized into a low-temperature, low-pressure liquid-gas mixture (the sudden pressure drop causes partial liquid evaporation, absorbing heat). This low-temperature, low-pressure two-phase refrigerant enters evaporator 12. In evaporator 12, the low-pressure liquid refrigerant absorbs heat from the surrounding environment (such as indoor air), completely evaporating into a low-temperature, low-pressure gas. This heat absorption causes a decrease in the surface temperature of evaporator 12, which is then delivered to the target space by a fan. It should be noted that this working principle is a conventionally used technique in existing technology. For a detailed description of the working principle, please refer to the collaborative working principle between compressor 11, evaporator 12, and condenser 20. This invention will not provide a detailed description here.

[0036] Further reference Figure 4 and Figure 7 The openings 202 are staggered and arranged at equal intervals.

[0037] The openings 202 are staggered in a group and arranged at equal intervals. At the same time, each group of openings 202 is distributed upward at equal intervals. The staggered arrangement allows the airflow or cooling medium to flow more smoothly through the condenser tube 203, thereby improving heat dissipation efficiency and ensuring that the heat inside the condenser tube 203 can be quickly removed. The openings 202 and the condenser tube 203 inside can be installed more compactly in a limited space, improving space utilization.

[0038] In a preferred embodiment, independent condenser tubes 203 are installed on the staggered openings 202, and the condenser tubes 203 are installed in a serpentine pattern inside the openings 202. On the openings 202 in the same row, the condenser tubes 203 are laid out in a serpentine pattern from the uppermost opening 202 to the lowermost opening 202, so that the condenser tubes 203 are fully distributed inside the condenser 20.

[0039] refer to Figures 1-7The condenser tube 203 has a condenser inlet pipe 204 and a condenser outlet pipe 205 distributed at its upper and lower ends, and a collection device is connected to the condenser inlet pipe 204 and the condenser outlet pipe 205.

[0040] The condensate inlet pipe 204 and the condensate outlet pipe 205 both extend to the same side wing sheet metal 21, with the condensate inlet pipe 204 on top and the condensate outlet pipe 205 on the bottom. The condensate inlet pipe 204 and the condensate outlet pipe 205 are bent perpendicularly to each other, and the bent parts of the condensate inlet pipe 204 and the condensate outlet pipe 205 are inserted into the collecting device.

[0041] In the above design, both the condensate inlet pipe 204 and the condensate outlet pipe 205 are designed on the same side wing sheet metal 21, which greatly simplifies the layout of the condensation system. This design makes pipe connections more intuitive and convenient, reducing the complexity and error rate during installation. It also reduces the increase in fluid resistance and energy loss that may result from pipe crossings or excessive length; further improving space utilization and facilitating the installation and connection of collection devices on the condensate inlet pipe 204 and the condensate outlet pipe 205.

[0042] Further reference Figure 3 and Figure 4 The collection device includes a liquid collection tube 206 and a drainage tube 207. Each independent condenser tube 203 is inserted into the liquid collection tube 206 at equal intervals, and the drainage tube 207 is connected to the inside of the liquid collection tube 206.

[0043] In a further implementation, each condenser tube 203 is inserted equidistantly into the collection tube 206, ensuring that the condensate is evenly distributed within the collection tube 206 and avoiding uneven distribution caused by condensate accumulation in a certain area. The equidistant insertion of the condenser tubes 203 and the connected drain pipe 207 make maintenance and cleaning of the entire condensation system easier. Maintenance personnel can easily access each condenser tube 203 and drain pipe 207 to perform necessary inspections and cleaning operations, ensuring the long-term stable operation of the system. This design improves condensation efficiency, ensuring that the condensate can be collected quickly and effectively; at the same time, the drain pipe 207 can evenly deliver the condensate into each condenser tube 203, improving the circulation of the condensate within the condenser tubes 203.

[0044] Preferred Solution Reference Figure 5 and Figure 6 Heat dissipation cores 210 are equidistantly distributed on both sides of the condenser tube 203.

[0045] The heat sink 210 has a cylindrical structure;

[0046] In a preferred embodiment, the heat dissipation cores 210 on both sides of the condenser tube 203 can increase the heat exchange area between the condenser tube 203 and the surrounding environment, thereby improving the condensation efficiency. During the condensation process, the heat released by the gaseous substance is rapidly transferred to the surrounding environment through the heat dissipation cores 210, allowing the gaseous substance to condense into a liquid state more quickly.

[0047] The cylindrical heat sink 210 is in close contact with the outer wall of the condenser tube 203, effectively increasing the heat exchange area and promoting uniform heat distribution. This avoids problems such as localized overheating or uneven cooling, allowing the heat inside the condenser tube 203 to be transferred to the surrounding environment more quickly. Compared to finned heat dissipation methods, the cylindrical heat sink 210 significantly reduces dust accumulation on the condenser 20, and reduced dust improves the overall heat dissipation performance of the condenser 20.

[0048] The heat sink 210 is made of metal materials, preferably iron, copper, and aluminum. The configuration is based on the customer's actual usage requirements.

[0049] Example 2:

[0050] refer to Figures 1-7 A rear sheet metal 22 is installed behind the heat dissipation shell 201, a mesh frame 208 is installed on the rear sheet metal 22, and a variable speed condenser fan 209 is installed on the mesh frame 208.

[0051] The variable speed condenser fan 209 is an EGB5220B motor with adjustable speed and variable direction, which is available on the market.

[0052] This invention allows for precise adjustment of motor speed according to actual refrigeration needs, resulting in high efficiency and energy saving. The motor in the variable speed condenser fan 209 has precise speed adjustment capabilities, enabling rapid and accurate adjustments based on the real-time operating conditions of the refrigeration system. It also boasts a wide speed adjustment range, allowing for flexible adjustment of motor speed across a broad spectrum. Furthermore, its variable direction function allows for high-speed backflushing for 60 seconds after power restoration to remove dust from the condenser fins. After 60 seconds, it automatically adjusts to forward rotation. When the condensing pressure exceeds the system setting P1 kg, the fan operates at a high speed of V1. When the condensing pressure is between the system setting P1 and P2, the fan operates at a speed of V2. When the condensing pressure falls below P2 kg, the fan speed drops to V3. After refrigeration is complete, the compressor 11 stops, and the variable speed condenser fan 209 stops after a 60-second delay (the specific control method here represents a working process; the actual control is achieved through a circuit program combined with sensor coordination, which can be understood as a computer control program).

[0053] The specific implementation process of this utility model is as follows:

[0054] The compressor 11 compresses the refrigerant, raising its temperature to approximately 80–100°C and its pressure to 15–30 bar. The high-temperature, high-pressure gas then enters the condenser 20. In the condenser 20, the high-temperature gas exchanges heat with the outside air (or water) and gradually cools into a high-pressure liquid (phase change releases heat). Through a throttling device (such as an expansion valve), the high-pressure liquid is depressurized into a low-temperature, low-pressure liquid-gas mixture (the sudden pressure drop causes some liquid to evaporate and absorb heat). The low-temperature, low-pressure two-phase refrigerant enters the evaporator 12. The low-pressure liquid refrigerant absorbs heat from the surrounding environment (such as indoor air) in the evaporator 12 and completely evaporates into a low-temperature, low-pressure gas. The heat absorption causes the surface temperature of the evaporator 12 to decrease, and the cold air is then delivered to the target space by a fan.

[0055] Each condenser tube 203 is inserted into the liquid collection tube 206 at equal intervals, ensuring that the condensate can be evenly distributed in the liquid collection tube 206; at the same time, the condensate can be evenly transported into each condenser tube 203 through the drainage tube 207, improving the circulation of the condensate in the condenser tube 203.

The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions can be made to this utility model within its substance and scope of protection.
