Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a condenser for a refrigerated vehicle. Background Art

[0002] ‌Refrigerated trucks are closed van transport vehicles used to transport frozen or fresh goods. They are refrigerated transport vehicles equipped with a refrigeration unit and a polyurethane insulated compartment. Small refrigerated vans are often used in urban logistics to transport frozen foods (refrigerated trucks), dairy products (dairy trucks), vegetables and fruits (fresh goods trucks), vaccines and medicines (vaccine trucks), etc. The air-conditioning system of refrigerated trucks uses a refrigeration device to reduce the temperature in the vehicle compartment. The refrigeration device mainly consists of three major components: a compressor, a condenser assembly, and an evaporator assembly, as well as the connecting pipes between the three major components. The compressor compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas and then transports it to the condenser assembly. The condenser assembly releases heat from the high-temperature and high-pressure refrigerant to the air, condensing it into The high-pressure, medium-temperature liquid flows to the expansion valve; the expansion valve reduces the pressure of the liquid refrigerant, turning it into a low-pressure, low-temperature gas-liquid mixture, which enters the evaporator; the low-pressure, low-temperature gas-liquid mixed refrigerant evaporates in the evaporator assembly, absorbs heat from the air, and thus reduces the temperature; and the refrigerated trucks in the prior art still mostly use a tube-and-fin condenser, the structure of which includes multiple tubes and multiple stacked flat fins. However, the tube-and-fin condenser with this structure has a poor layout of tubes and fins, resulting in poor ventilation and poor heat exchange effect of the entire core. In addition, the area of ​​the fins is excessively increased, making the ventilation gap inside the condenser assembly smaller, and then the actual heat exchange effect of the fins is not significantly improved due to poor ventilation, but the production cost is increased.

[0019] In this embodiment, the fluid that needs to dissipate heat in the refrigeration system of the refrigerated truck flows into the collecting pipe 6 on one side of the fixed frame 1 through the infusion pipe, and the fluid in the collecting pipe 6 on this side of the fixed frame 1 will flow into the corresponding collecting pipe 6 on the other side of the fixed frame 1 through the connected inner condenser pipe 2 and outer condenser pipe 3 and flow out through the corresponding infusion pipe. When the fluid flows inside the inner condenser pipe 2 and the outer condenser pipe 3, the fluid will rotate in a spiral shape under the influence of the guide groove 10 opened on the inner side of the heat conduction pipe 9, which can then help enhance the uniformity of the fluid heat dissipation. When the external airflow flows through the inside of the fixed frame 1, the airflow will first contact the outer condenser pipe 3, and then contact the inner condenser pipe 2 and the heat dissipation plate 5. Moreover, the heat dissipation ring 4 arranged on the surface of the inner condenser pipe 2 and the outer condenser pipe 3 can effectively increase the area of ​​the outer surface of the inner condenser pipe 2 and the outer condenser pipe 3, and increase the effective contact area between the heat dissipation components inside the condenser and the airflow, thereby helping to enhance the heat dissipation effect of the condenser and ensuring that the refrigerated truck has a good cooling effect.

[0020] As a preferred embodiment, the fixing frame 1 is in a U-shaped structure, and a group of protective nets 7 are fixedly connected to the openings on both sides of the fixing frame 1, and three groups of collecting pipes 6 are fixedly connected to the outer side surfaces on both sides of the fixing frame 1.

[0021] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 The setting of the fixed frame 1 and the protective net 7 can effectively enhance the protection effect of the condenser on the inner condenser tube 2 and the outer condenser tube 3, and reduce the probability of the inner condenser tube 2 and the outer condenser tube 3 being damaged due to accidents.

At the same time, the inner cavities of the inner condenser tube 2 and the outer condenser tube 3 are movably connected to the heat transfer tube 9.

[0023] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 The structural arrangement of the inner condenser tube 2 and the outer condenser tube 3 can not only increase the contact area with the airflow, but also effectively reduce the obstruction effect on the airflow flow, ensure the smoothness of the airflow when flowing inside the condenser, and assist in enhancing the heat dissipation effect of the condenser.

At the same time, the setting of the heat pipe 9 makes the inner condenser tube 2 and the outer condenser tube 3 both have a double-layer structure, which can reduce the probability of fluid leakage due to damage to the condenser structure.

[0026] As a preferred embodiment, the two ends of multiple groups of inner condenser tubes 2 and multiple groups of outer condenser tubes 3 in the same vertical plane in the fixed frame 1 are respectively connected to corresponding collecting pipes 6, and adjacent inner condenser tubes 2 and outer condenser tubes 3 are staggered.

[0027] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 The corresponding collecting pipe 6 enables the inner condenser tube 2 or the outer condenser tube 3 in the same vertical plane in the fixed frame 1 to flow in and out of the fluid synchronously, thereby realizing the diversion and heat dissipation of the fluid to be cooled in the refrigeration system of the refrigerated truck and enhancing the heat dissipation effect of the condenser.

[0028] As a preferred embodiment, the outer surfaces of the inner condenser tube 2 and the outer condenser tube 3 are fixedly connected with multiple groups of heat dissipation rings 4 in parallel and equidistantly along the length direction, and the heat dissipation rings 4 are annular in structure, and the axial cross-section of the heat dissipation rings 4 is a semicircular structure.

[0029] In this embodiment, if Figure 2 、 Figure 3 and Figure 4 The setting of the heat dissipation ring 4 can effectively increase the effective area of ​​the inner condenser tube 2 and the outer condenser tube 3 in contact with the airflow, thereby enhancing the heat dissipation effect of the condenser.

[0030] As a preferred embodiment, the inner cavity of the fixed frame 1 is fixedly connected with multiple groups of fixed rods 8 in parallel and at equal intervals, and the fixed rods 8 are of a rectangular structure, and the surface of the fixed rods 8 is fixedly connected with multiple groups of heat dissipation plates 5 at equal intervals along the length direction, and the heat dissipation plates 5 are of a rectangular structure as a whole, and the heat dissipation plates 5 and adjacent heat dissipation rings 4 are staggered.

[0031] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 The setting of the fixing rod 8 allows the surface of the heat sink 5 to fit the surfaces of the inner condenser tube 2 and the outer condenser tube 3 respectively through the corresponding grooves, so that the inner condenser tube 2 and the outer condenser tube 3 can form a whole, increasing the effective area of ​​the internal heat dissipation structure of the condenser, thereby ensuring the heat dissipation effect inside the condenser, and the inner condenser tube 2 and the outer condenser tube 3 are staggered with the heat dissipation ring 4 and the heat sink 5, so that a ventilation gap of appropriate size can be left inside the condenser to ensure the circulation effect of airflow.
