Description

Technical Field

[0001] This utility model relates to the field of heat exchange technology, specifically to an isolated rapid heat exchange device. Background Technology

[0002] The industrial sector is one of the main application areas for heat recovery. Heat exchange technology can recover various types of waste heat generated during production processes, converting waste heat that might otherwise be lost into usable thermal energy, thereby improving energy efficiency and reducing energy waste. This process typically relies on highly efficient heat exchange devices that effectively facilitate the transfer of heat from the heat source to the cold source (or the heat-absorbing medium).

[0003] In traditional heat recovery methods, heat sources and cold sources (or endothermic media) often exchange heat through direct contact. While this direct contact method is simple and straightforward, it presents significant problems in certain situations. Particularly in some chemical industries, heat sources are often corrosive, such as waste liquids containing acidic or alkaline substances. When these corrosive heat sources come into direct contact with the cold source or endothermic media, they can cause corrosion of the heat exchange equipment, leading to serious consequences such as leaks, performance degradation, and even equipment failure. Therefore, in heat recovery processes involving corrosive heat sources, additional protective measures must be taken, such as using corrosion-resistant materials and adding anti-corrosion coatings, to ensure the stability and safety of the system. However, these solutions often come with high manufacturing costs and complexity. Therefore, developing a new type of heat exchange device that can effectively recover heat from corrosive heat sources while maintaining system stability and economy has become a pressing technical challenge in the field of heat management and energy utilization. Summary of the Invention

[0004] In view of the problems existing in the prior art, this utility model provides an isolated rapid heat exchange device. By adopting physical isolation, direct contact between the heat source and the heat-absorbing working medium is avoided, thereby effectively solving the problem of corrosion of heat exchange equipment by corrosive heat sources.

[0005] The technical solution adopted by this utility model is as follows: an isolated rapid heat exchange device includes a heat exchange pipe for flowing heat-absorbing working fluid, and multiple slender heat-conducting pipes are evenly spaced in the axial direction of the heat exchange pipe. The heat-conducting pipe is a closed pipe with an inner cavity. A heat-conducting medium is provided in the inner cavity of the heat-conducting pipe. The heat-conducting pipe is sealed to the heat exchange pipe, and one end extends into the heat exchange pipe to contact the heat-absorbing working fluid flowing therein, while the other end is inserted into a heat source.

[0006] Furthermore, the heat-conducting pipe and the heat exchange pipe are connected by a detachable sealed connection.

[0007] Furthermore, the heat exchange pipeline includes a main liquid supply pipeline and a main liquid return pipeline, which are connected by multiple branch pipes, and each branch pipe is equipped with a heat-conducting pipe.

[0008] This utility model's isolated rapid heat exchange device uses multiple heat-conducting pipes for heat conduction, transferring heat from the heat source to the heat-absorbing medium within the heat exchange pipes, thereby achieving rapid heat exchange. It achieves physical isolation between the heat exchange pipes and the heat source, avoiding direct contact between the heat source and the heat-absorbing medium, thus effectively solving the corrosion problem of corrosive heat sources on the heat exchange equipment. The layout of the main liquid supply pipe, main liquid return pipe, and multiple branch pipes, combined with the heat-conducting pipes, improves the efficiency of heat exchange. The heat-conducting pipes and the heat exchange pipes are connected by a detachable sealed connection, facilitating replacement or maintenance of the heat-conducting pipes when needed.

The heat-conducting pipes 200 can be made of corrosion-resistant materials with high thermal conductivity to improve heat transfer efficiency. A suitable heat-conducting medium, such as a phase change material, nanofluid, or high thermal conductivity oil, is selected based on the properties of the heat source and the working fluid. The heat-conducting pipes 200 are sealed to the heat exchange pipe, with one end extending into the heat exchange pipe to contact the heat-absorbing working fluid flowing through it, and the other end inserted into the heat source for efficient heat transfer.

[0013] To facilitate the replacement and maintenance of the heat pipe 200, a detachable sealed connection is adopted between the heat pipe 200 and the heat exchange pipeline.

[0014] To improve heat exchange efficiency, the heat exchange pipeline includes a main liquid supply pipeline 101 and a main liquid return pipeline 102.
