Description

Technical Field

[0001] The utility model relates to the technical field of thermal energy environmental protection machinery, in particular to an energy-saving heat exchange device. Background Technique

[0002] In today's society, with the continuous growth of energy demand and the improvement of environmental protection awareness, energy conservation and emission reduction have become the focus of global attention. Especially in the industrial production process, as an important secondary energy source, the effective utilization of thermal energy is of great significance for reducing production costs, improving energy efficiency and reducing environmental pollution. As a heat energy recovery and conversion device widely used in various industries, the optimization of the performance of the heat exchanger is directly related to the energy utilization efficiency of the entire system.

[0003] Traditional heat exchange devices mostly adopt structures such as shell-and-tube type, plate type or fin type. Although these types of heat exchangers can meet the basic usage requirements in many cases, they generally have problems such as low heat transfer efficiency, large volume, complex installation and maintenance, and high cost. Especially in occasions where rapid and efficient heat exchange is required, such as district heating systems, industrial cooling circulation systems, etc., the performance of traditional heat exchange devices often cannot reach the optimum.

[0004] In addition, a key problem in the heat exchange process is heat loss. In many existing designs, due to insufficient insulation measures, a large amount of heat is dissipated during the transfer process, resulting in a reduction in heat exchange efficiency. At the same time, the flow design of the heat exchange medium also affects the heat exchange effect. An inappropriate flow channel design will increase the fluid resistance, reduce the heat exchange power, and thus affect the overall performance.

[0005] In terms of maintenance, due to the fixed structure of traditional heat exchangers, once a failure occurs or components need to be cleaned or replaced, professional tools and technicians are often required, consuming a lot of time and cost. This undoubtedly increases the operating cost for application occasions that require frequent maintenance or component replacement. Content of the Utility Model

[0039] As shown Figure 1-7 in FIGS.

[0040] The present utility model is an energy-saving heat exchange device, and its working principle is based on the heat exchange principle, that is, heat is transferred from a medium with a higher temperature to a medium with a lower temperature. The outer housing 1 of the present utility model is used to provide the structural support for the entire device. The heat preservation housing 2 is located inside the outer housing 1 and is used to reduce heat dissipation. The inner housing 3 is arranged inside the heat preservation housing 2, and the inside of the inner housing 3 is filled with a heat exchange medium (water or oil), which forms a heat exchange area in combination with the cold water pipe 7. The heat exchange pipe bracket 4 includes two sliding plates 41, and L-shaped bending blocks 42 are symmetrically fixed on each sliding plate 41 to form a groove 6 for supporting and fixing the hot water pipe 5. Both the inner housing 3 and the hot water pipe 5 can be disassembled in a way that can be pulled out, which is convenient for installation and maintenance. The hot water pipe 5 is wound in an S shape, and water circulation is carried out through the hot water inlet 51 and the hot water outlet 52 to transfer heat to the cold water pipe 7. The cold water pipe 7 is in a semi-pipe structure and is spirally wound outside the inner housing 3, and water circulation is carried out through the cold water inlet 71 and the cold water outlet 72 to absorb the heat of the hot water pipe 5, and the absorption efficiency is relatively high. The sealing assembly 8 ensures the sealing performance at the joints of the hot water pipe 5 and the cold water pipe 7 with the inner housing 3 and the outer housing 1 to prevent leakage. The universal wheels 9 are installed at the bottom of the outer housing 1 to facilitate the movement of the device. The armrest bracket 10 and the armrest 11 provide convenience when moving the device.

[0041] Working process:

[0042] Hot water enters the hot water pipe 5 from the hot water inlet 51. Since the hot water pipe 5 is wound in an S shape, the heat exchange area is increased and the heat exchange efficiency is improved. When the hot water flows through the hot water pipe 5, it transfers heat to the cold water pipe 7 in contact with it. Cold water enters the cold water pipe 7 from the cold water inlet 71. The cold water pipe 7 is a semi-pipe and is welded to the outside of the inner housing 3 as a whole. This design enables the cold water to better absorb the heat transferred from the hot water pipe 5. As the hot water and cold water flow in their respective pipes, heat is continuously transferred from the hot water to the cold water to achieve heat exchange. After heat exchange, the hot water flows out from the hot water outlet 52, while the heated cold water flows out from the cold water outlet 72, completing the recovery and utilization of thermal energy. The sealing component 8 ensures that there is no water leakage during the operation of the system, guaranteeing the sealing performance and safety of the system. The user can conveniently move the entire device through the armrest 11 and the armrest bracket 10, while the universal wheels 9 provide flexible mobility.
