Description

Technical Field

[0001] This utility model relates to the field of thermal energy technology, specifically to a high-efficiency heat exchange mechanism. Background Technology

[0002] A heat exchanger is a core device that uses heat exchange technology to transfer heat between gases. It is widely used in industries, energy, construction, and thermal energy. Its core function is to achieve heat transfer by optimizing thermal energy utilization efficiency.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] In existing equipment, because most of the hot air pipes are flat, cold air passes directly and quickly through the heat exchange channel, resulting in the cold air heat exchange efficiency not being maximized. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency heat exchange mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat exchange mechanism, including a gas collecting hood, a cold air inlet installed on one side of the gas collecting hood, a heat-resistant fan installed on the inner wall of the cold air inlet, a hot air inlet installed on the other side of the gas collecting hood, a hot flue gas inlet installed at one end of the gas collecting hood, a heat-resistant steel inner air duct connected to one side of the hot flue gas inlet, a heat-resistant steel heat sink installed on one side of the heat-resistant steel inner air duct, and a heat-resistant guide fan installed on the inner wall of the heat-resistant steel inner air duct.

[0007] The beneficial effects of this utility model are as follows: By adding heat-resistant steel heat sinks, the heat-resistant steel heat sinks improve the heat exchange efficiency of the cold air through the annular hollow channel between the air collecting hood and the heat-resistant steel inner air duct, thanks to their high thermal conductivity. At the same time, the total heat exchange area is increased by stacking multiple annular plates, and the narrow channel between the annular plates slows down the airflow speed, prolongs the contact time between the gas and the heat-resistant steel heat sinks, and further enhances the heat exchange effect, enabling the heat-resistant steel heat sinks to efficiently heat the passing cold air for heat exchange.

[0008] To achieve the introduction of cold air:

[0009] Further configuration: the central axis of the heat-resistant fan coincides with the horizontal central axis of the air vent.

[0010] By adopting the above technical solution, during heat exchange, the heat-resistant fan rotates to draw in cold air from the cold air inlet and discharge it from the hot air inlet on the other side, so that the cold air can exchange heat.

[0011] To achieve the introduction of hot flue gas:

[0012] Further configuration: the central axis of the heat-resistant guide fan coincides with the transverse central axis of the heat-resistant steel inner air duct.

[0013] By adopting the above technical solution, during heat exchange, the heat-resistant guide fan rotates to draw in hot flue gas from the hot flue gas inlet, so that the hot flue gas enters from one side of the heat-resistant steel inner duct and exits from the other side, thereby heating the heat-resistant steel inner duct and the heat-resistant steel heat sink.

[0014] To achieve rapid heat conduction within the heat-resistant steel inner duct:

[0015] Further configuration: heat-resistant steel heat sinks are evenly arranged along the outer surface of the heat-resistant steel inner air duct.

[0016] By adopting the above technical solution, when hot flue gas flows through the heat-resistant steel inner duct, the heat-resistant steel heat sink uses its high thermal conductivity to conduct the heat of the flue gas to itself, thereby facilitating heat exchange with the cold air.

[0017] To achieve the heat exchange effect of cold airflow:

[0018] Further configuration: The space between the gas collection hood and the heat-resistant steel inner air duct is hollow.

[0019] By adopting the above technical solution, when the heat-resistant fan rotates to draw in air, the cold air will pass through the hollow channel between the air collection shroud and the heat-resistant steel inner air duct, so that the heat-resistant steel heat sink can heat the cold air to exchange heat.

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0028] Please see Figures 1 to 5 A high-efficiency heat exchange mechanism includes a gas collection hood 1, a cold air inlet 2 installed on one side of the gas collection hood 1, a heat-resistant fan 3 installed on the inner wall of the cold air inlet 2, a hot air inlet 4 installed on the other side of the gas collection hood 1, a hot flue gas inlet 5 installed at one end of the gas collection hood 1, a heat-resistant steel inner air duct 6 connected to one side of the hot flue gas inlet 5, a heat-resistant steel heat sink 7 installed on one side of the heat-resistant steel inner air duct 6, and a heat-resistant guide fan 8 installed on the inner wall of the heat-resistant steel inner air duct 6.

[0029] In this embodiment, as Figure 2 As shown, the central axis of the heat-resistant fan 3 coincides with the transverse central axis of the air vent 2.

[0030] In this embodiment, as Figure 4 As shown, the central axis of the heat-resistant guide fan 8 coincides with the transverse central axis of the heat-resistant steel inner air duct 6.

[0031] In this embodiment, as Figure 3 As shown, the heat-resistant steel heat sink 7 is evenly arranged along the outer surface of the heat-resistant steel inner air duct 6.

[0032] In this embodiment, as Figure 5 As shown, the space between the gas collection hood 1 and the heat-resistant steel inner air duct 6 is hollow.

[0033] The working process of this high-efficiency heat exchange mechanism is as follows:

[0034] First, the heat-resistant guide fan 8 rotates to draw in the filtered hot flue gas from the previous process through the hot flue gas inlet 5. This allows the hot flue gas to enter from one side of the heat-resistant steel inner duct 6 and exit from the other side. As the hot flue gas flows through the heat-resistant steel inner duct 6, the heat-resistant steel heat sink 7 uses its high thermal conductivity to transfer the heat from the flue gas to itself, heating both the heat-resistant steel inner duct 6 and the heat-resistant steel heat sink 7. Then, the heat-resistant fan 3 rotates to draw in cold air through the cold air inlet 2. The cold air passes through the annular hollow channel between the air collecting hood 1 and the heat-resistant steel inner duct 6, coming into contact with the heat-resistant steel heat sink 7. This allows the heat-resistant steel heat sink 7 to heat the passing cold air, thus exchanging heat. Finally, the heated hot air exits from the hot air inlet 4 on the other side, allowing the cold air to exchange heat as well.
