Background Art

[0002] A heat exchange device transfers heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the temperature of the fluid reaches the specified index of the process to meet the requirements of process conditions. It is also one of the main devices for improving energy utilization efficiency. However, the currently used heat exchange devices still have the following problems: First, two heat flows cannot be heat-exchanged simultaneously. For example, when heat-exchanging gas-liquid two-phase flows, two sets of heat exchange equipment are required, increasing the cost of heat exchange equipment; Second, it is difficult to control the heat exchange temperature of two heat flows. For example, when heat-exchanging gas-liquid two-phase flows as mentioned in the first problem, due to the different physical properties of gas and liquid in two forms of fluid, it is not easy to make the temperatures of gas-liquid two-phase flows the same after heat exchange through two sets of heat exchange equipment, which will affect the use effect of some special equipment; Third, the vibration during operation is likely to damage the heat exchange equipment.

[0077] In the present invention, the three-way cold flow mixing and temperature equalizing device realizes the mixing and temperature equalizing of three cold flows, that is, the cold flows in the front and rear regions of the hot flow tube 3 and the cold flow inside the cold flow tube 14 are mixed through the mixing flow tube 4 in the three-way cold flow mixing and temperature equalizing device. These three cold flows exchange heat with each other during the mixing process, and then flow out of the mixing flow tube 4 in a uniform and isothermal state, and perform isothermal heat exchange with the hot flows in the front and rear regions of the subsequent hot flow tube 3, ensuring synchronous and isothermal heat exchange of the hot flows in the two regions.

[0078] In the present invention, a chamfered surface is provided on the outer end surface of the mixing flow tube 4.

Through this design, the cold flow flowing in through the connecting tube 16 and the cold flow flowing in through the round hole 21 of the cold flow tube 14 are mixed, and flow through the gap between the spoiler F26 and the mixing flow tube 4 to the region between the spoiler F26 and the baffle B27, so that the cold flows can be fully mixed and heat exchanged.

Through this design, it can not only guide the mixed cold flow between the baffle A24 and the spoiler E22, but also play a role in disturbing the mixed cold flow, making the cold flow form a vortex flow, promoting full heat exchange between the cold flows, and flowing out in an isothermal form.
