[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0026] like Figure 1 and Figure 2As shown, a plate-tube heat exchanger for a slaughter scalding tank includes an input pipe 1 for introducing a heat medium, an input pipe 1 connected to a heat exchange tube 2 via an input end 5, and an output pipe 3 connected to the other end of the heat exchange tube 2 via an output end 6.
[0027] The heat medium is input into the heat exchange tube 2 through the input end 5 and then output from the output tube 3 through the output end 6. The heat exchange tube 2 is provided with fins 4 to increase the heat transfer area, which can effectively increase the heat transfer area and improve the heat exchange efficiency.
[0028] Specifically, the heat exchange tubes 2 are arranged in a multi-passage, S-shaped configuration, which allows the heat medium to flow within the heat exchange tubes 2. This extends the path of the heat medium, increases the contact time and distance between the medium and the inner wall of the heat exchange tubes, and ensures sufficient contact between the medium and the heat exchange tubes 2, thereby improving the adequacy of heat transfer. This arrangement helps to break the laminar boundary layer of the fluid flow, allowing the fluid to form a more complex flow state within the heat exchange tubes 2, increasing the degree of turbulence and improving the heat transfer coefficient.
[0029] Meanwhile, the extended path of the S-shaped heat exchange tube 2 allows for full contact with the water in the scalding tank, increasing the contact area and achieving efficient heat transfer. Its inlet pipe 1 and outlet pipe 3 are located on the same side of the heat exchange tube 2, facilitating pipe connection and smooth flow of the medium.
[0030] Furthermore, the lower end of heat exchange tube 2 is connected to the input end 5, and the upper end is connected to the output end 6, so that the heat medium can flow through the heat exchange tube 2 from bottom to top, thereby further improving the heat exchange efficiency.
[0031] like Figure 4 and Figure 5 As shown, the heat exchange tubes 2 are set in two groups and arranged in parallel on the sides of the inlet pipe 1 and the outlet pipe 3 to increase the heat exchange area and meet the hot water requirements of slaughtering scalding tanks of different sizes.
[0032] In addition, the heat exchange tubes 2 are set in at least two sets and are arranged in a staggered manner on the side of the inlet pipe 1 and the outlet pipe 3. The heat exchange tubes 2 can also be set in three or more sets, arranged in parallel or staggered arrangement, to meet the hot water requirements of slaughtering scalding tanks of different sizes.
[0033] Further, such as Figure 1 and Figure 4 As shown, fins 4 are radially connected to the outer ring of heat exchange tube 2, increasing the heat dissipation area on the outside of the heat exchange tube and effectively improving the heat exchange efficiency between the heat exchange tube and the external fluid. Figure 3 As shown, the number of fins 4 can be adjusted according to the actual situation, either densely or sparsely.
[0034] At the same time, the fins 4 of the adjacent heat exchange tubes 2 arranged in an S-shape are connected to each other, so that the fins of the entire heat exchanger form a continuous whole, which enhances the stability and rigidity of the structure, and also reduces the heat loss during the transfer process, forming a compact heat exchange structure and enhancing the overall heat exchange effect.
[0035] In this embodiment, the number of input terminals 5 and output terminals 6 can be set according to the number of heat exchange tubes 2, ensuring that each heat exchange tube 2 can be independently and evenly connected to the input tube 1 and the output tube 3, so that the flow distribution of the heat medium in each heat exchange tube 2 is more uniform, avoiding the difference in heat exchange efficiency caused by uneven flow, ensuring that all heat exchange tubes 2 can play a full role, and improving the heat exchange effect and performance stability of the entire heat exchanger 2.
[0036] Furthermore, the heat exchange tube 2 is installed inside the fixed frame 7, while the inlet pipe 1 and outlet pipe 3 are located on the side of the fixed frame 7. This layout makes the overall structure of the heat exchanger more regular and facilitates connection and installation with other piping systems. At the same time, it also provides more convenient operating space when maintenance and repair of the heat exchange tube 2 or the piping system are required.
[0037] Its input end 5 is located on the lower side of the fixed frame 7, and its output end 6 is located on the upper side of the fixed frame 7, so that the heat medium can flow through each heat exchange tube 2 from bottom to top, further improving the heat exchange efficiency. The support feet 8 on the lower side of the fixed frame 7 provide stable support for the entire heat exchanger, and the hanging lug structure 9 on the upper side facilitates the installation and fixation of the heat exchanger, so that it can be placed stably in a suitable position in the slaughtering scalding tank.
[0038] In this embodiment, both the input pipe 1 and the output pipe 3 are connected to an air-source heat pump system. The heat medium is a refrigerant, which is a crucial heat medium in the air-source heat pump system, such as R134a or R410A. The refrigerant circulates within the heat pump system, transferring and upgrading heat through absorption and release. In the plate-tube heat exchanger, the high-temperature, high-pressure refrigerant gas transfers heat to water or other heat media, thereby heating the scalding tank.
[0039] In the heating process of the air source heat pump system in this embodiment, the heat pump does not directly convert electrical energy into heat energy through resistance heating. Instead, it uses a small amount of electricity to drive the compressor to "transfer" the existing heat energy in the air to the water in the hot tub. In this process, the heat pump only needs 1 kWh of electricity to bring back 4 kWh of heat energy. Therefore, its energy-saving efficiency can reach about 75%. In addition, compared with boilers, using air source heat pumps can also eliminate various related fees, such as environmental protection and safety testing fees, operator training fees, qualification certificate annual inspection fees, and operator labor costs.
[0040] In this embodiment, the heat exchange tube 2 of the plate-tube heat exchanger used in the scalding tank is made of metal pipes with good thermal conductivity and corrosion resistance, and is tightly fitted with heat exchange fins 4 to effectively increase the heat exchange area, thus forming a plate-tube heat exchanger suitable for installation in the scalding tank. High-temperature refrigerant or other working fluids (mediums) are introduced through external equipment such as a heat pump and continuously circulate within the heat exchanger to exchange heat with the water in the scalding tank, thereby raising the water temperature in the scalding tank to a suitable temperature for scalding and maintaining a constant temperature to ensure the smooth progress of the slaughtering process. The plate-tube heat exchanger consists of three parts: a high-temperature (high-pressure) working fluid input pipe 1, a plate-tube heat exchange tube 2 body, and a low-temperature (low-pressure) working fluid output pipe 3.
[0041] This plate-tube heat exchanger significantly increases the heat exchange area, greatly improves heat exchange efficiency, and shortens water heating time by more than 20%. It significantly improves the energy efficiency of the equipment; at the same time, it reduces the operating pressure of the heat pump compressor, effectively protecting the compressor and significantly extending its service life.
[0042] This utility model features a rationally designed plate-tube heat exchanger. Through the multi-pass S-shaped arrangement of heat exchange tubes 2 and fins 4, it significantly improves heat exchange efficiency, rapidly transferring heat from the heat medium to the water in the scalding tank, raising the water temperature and maintaining a constant temperature within the slaughtering scalding tank. Furthermore, it is easy to install and maintain. The structural design of the fixing frame 7, support feet 8, and hanging lug structure 9 ensures stable installation in the slaughtering scalding tank environment and facilitates daily maintenance. It possesses excellent practicality and reliability, making it suitable for scalding tank heating applications in the slaughtering industry.
[0043] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
