Detailed Description

The technical solution of the present application is further described in detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, a heat exchanger disclosed in an embodiment of the present application is composed of a main body 11, heat exchange plates 12, an inflow tank 13, an outflow tank 14, an inflow pipe 15, an outflow pipe 16, a fan 17, and the like, specifically, the number of the heat exchange plates 12 is plural, the heat exchange plates 12 are arranged in the main body 11 at intervals, and a gap is formed between adjacent heat exchange plates 12, and the gap is used for providing air flow. The external air flows into the gaps between the heat exchange plates 12 and then contacts the heat exchange plates 12 at both sides, thereby performing heat exchange.

The inflow box 13 is arranged on the main body 11 and is positioned below the heat exchange plates 12, the outflow box 14 is arranged on the main body 11 and is positioned above the heat exchange plates 12, the inflow box 13 is arranged on the main body 11 and is positioned below the heat exchange plates 12, the inflow box 13 and the outflow box 14 are used for connecting the heat exchange plates 12 into a circulation loop, after entering the inflow box 13, a heat exchange medium respectively flows into the channel 121 in each heat exchange plate 12, then flows into the outflow box 14, then flows out of the outflow box 14 and enters subsequent heat exchange equipment, the collected heat is transferred to liquid water in the heat exchange equipment, and then flows back into the inflow box 13, and the circulation process is continuously carried out.

The fan 17 is disposed on the main body 11 and above the heat exchange plates 12, and functions to drive air to rapidly flow through the gaps between the heat exchange plates 12, so as to accelerate the heat exchange.

On the whole, the heat exchanger that this application embodiment provided uses the mode of plate heat transfer to improve the exchange efficiency of closed heat source tower heat exchange, and plate heat transfer can provide bigger heat transfer area, effectively improves the area of contact of heat transfer medium and air. In addition, the working surface of the heat exchange plate 12 is flat, so that defrosting is convenient to perform in a low-temperature environment, and the heat exchange efficiency in a low-temperature operation environment can be improved to a certain extent.

Referring to fig. 3 and 4, as a specific embodiment of the heat exchanger provided by the application, the heat exchange fins 2 are uniformly distributed on the side walls of the two sides of the heat exchange plate 12, and the heat exchange fins 2 can further increase the contact area between the heat exchange plate 12 and air, that is, the heat exchange area, and can further improve the heat exchange efficiency.

Referring to fig. 3 and 4, as an embodiment of the heat exchanger provided by the application, the heat exchange fin 2 is arc-shaped, and the higher end of the heat exchange fin 2 is located below the fan 17, and the lower end of the heat exchange fin faces the space outside the main body 11. The heat exchange fins 2 of this shape are capable of guiding the air between the two heat exchange plates 12 to follow a set route.

It will be appreciated that without the heat exchange fins 2, the air blown by the fan 17 would first move in a direction close to the bottom surface of the main body 11, and then flow to both sides after contacting the bottom surface of the main body 11 or the inflow tank 13, which obviously reduces the flow velocity of the air. After being guided by the heat exchange fins 2, the air blown by the fan 17 can flow along a predetermined path, and can flow out of the main body 11 more quickly.

Referring to fig. 5, as a specific embodiment of the heat exchanger provided by the application, the heat exchange fins 2 on two adjacent heat exchange plates 12 are arranged in a staggered manner, so that air circulation channels partitioned by the heat exchange fins 2 are communicated, distribution of air pressure is relatively uniform, and in addition, the heights of the heat exchange fins 2 can be appropriately increased, which is beneficial to further increasing the heat exchange area.

Referring to fig. 5, in an embodiment of the heat exchanger provided by the application, the heat exchange fins 2 are inclined toward the bottom surface of the main body 11 in a direction away from the heat exchange plates 12, so that the air blown by the fan 17 can be guided to flow toward the bottom surface of the main body 11 quickly, which helps to increase the flow speed of the air in the main body 11.

Referring to fig. 6, as a specific embodiment of the heat exchanger provided by the application, in the flowing direction of the heat exchange medium, the flow area of the channel 121 in the heat exchange plate 12 tends to increase, it should be understood that the volume of the heat exchange medium in the channel 121 increases after absorbing heat, and a proper increase of the flow area of the channel 121 can play a role in reducing pressure, which is helpful to improve safety during use.

The embodiment of the application also discloses a closed heat source tower, which comprises any one of the heat exchangers recorded in the content.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
