The fins are arranged in a spiral or serpentine shape to increase the heat exchange area and improve the heat exchange effect to achieve the efficiency that occurs within a fixed range.

Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange generators, and in particular to a heat exchanger with a countercurrent structure generator having an excellent structure and suitable for vehicle and ship exhaust refrigeration and ice making scenarios. Background Art

[0002] As a common waste heat source, vehicle and ship exhaust has the characteristics of high temperature, high pressure and complex composition. With the increasing awareness of environmental protection, how to use this waste heat for refrigeration and ice making to achieve energy reuse has become a research hotspot. However, in the process of using vehicle and ship exhaust for refrigeration and ice making, traditional heat exchangers often face a series of challenges.

[0003] First, the high temperature and high pressure characteristics of vehicle and ship exhaust put forward extremely high requirements on the structural strength of the heat exchanger. High temperature will cause the material performance to deteriorate, making the heat exchanger vulnerable to damage; while high pressure will easily cause the heat exchanger shell and internal components to deform or even damage, thus affecting the normal operation and service life of the heat exchanger. In extreme cases, it may also cause safety accidents.

[0004] Secondly, the complexity of the operating environment of vehicles and ships also puts a severe test on the performance of heat exchangers. Under long-term turbulence, vibration and harsh weather conditions, traditional heat exchangers are difficult to maintain high-efficiency heat exchange performance in a long-term and stable manner. This not only reduces the efficiency of refrigeration and ice making, but may also have a negative impact on the overall operating performance of vehicles and ships.

[0005] Therefore, it is particularly important to invent a countercurrent structure generator suitable for vehicle and ship exhaust refrigeration and ice making scenarios, which has excellent structural pressure resistance and high temperature resistance. Summary of the invention

[0006] The present invention proposes a novel countercurrent structure generator for refrigerating and making ice from vehicle and ship exhaust gas, aiming to provide a generator with high structural strength, high temperature resistance, corrosion resistance and high heat exchange efficiency to meet the special needs of refrigerating and making ice from vehicle and ship exhaust gas.

[0013] Preferably, the guide plate of the countercurrent structure generator is arranged at the inlet and outlet of the heat exchange tube, and is used to guide the flow direction of the exhaust gas and the coolant of the vehicle or ship, so as to realize countercurrent heat exchange.

[0014] Furthermore, the shell is made of a nickel-based alloy with a temperature resistance range of over 400 degrees Celsius and a compressive strength of over 15 MPa, so as to ensure structural stability under high temperature and high pressure environments.

[0015] In addition, flow control valves are provided at the coolant inlet and outlet to adjust the flow of the coolant to meet different refrigeration and ice-making requirements.

[0016] The present invention also includes a method of using the novel countercurrent structure generator for refrigerating and making ice from vehicle and vessel exhaust gas, and the specific steps are as follows:

[0017] S1: Introduce the exhaust gas of vehicles and ships into the shell through the air inlet;

[0018] S2: The exhaust gas of vehicles and ships conducts countercurrent heat exchange with the coolant in the countercurrent heat exchange component to achieve heat transfer;

[0019] S3: The exhaust gas of the vehicle or ship after heat exchange is discharged from the outer shell through the outlet;

[0020] S4: After the coolant absorbs the heat, it is discharged through the coolant outlet and used for refrigeration and ice making;

[0021] S5: Adjust the flow control valve as needed to control the flow of coolant and the cooling effect.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. High structural strength: The shell and countercurrent heat exchange components are made of high-strength, high-temperature resistant nickel welding materials and nickel alloy materials, ensuring the structural stability of the heat exchanger under high temperature and high pressure environment.

[0028] 6. Easy maintenance: Nickel welding materials have good formability, the welding process is simple and fast, suitable for mass production, reducing manufacturing costs and maintenance difficulties.
