Detailed Description

The technical solutions of the present utility model will be clearly and completely described in connection with the embodiments, and it is obvious that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, a fire tube with high heat exchange rate includes a fire tube body 1, wherein the inside of the fire tube body 1 is in a through arrangement, a plurality of small heat exchange tubes 2 are connected to the side wall of the fire tube body 1 from top to bottom in a through manner, and projections of two adjacent small heat exchange tubes 2 are in a cross shape.

As a technical optimization scheme of the utility model, the small heat exchange tube 2 is arranged along the diameter direction of the fire tube body 1. So that the plurality of small heat exchange tubes 2 are uniformly distributed on the fire tube body 1 and can not be staggered with each other, and the installation of the fire tube body 1 in use can not be disturbed.

As a technical optimization scheme of the utility model, both ends of the small heat exchange tube 2 extend to the outside of the side wall of the fire tube body 1. The small heat exchange tube 2 can be connected with a preset refrigerant tube, so that the refrigerant in the small heat exchange tube 2 can normally flow, and heat can be efficiently absorbed.

As a technical optimization scheme of the utility model, the outer diameter of the small heat exchange tube 2 is smaller than the inner diameter of the fire tube body 1. After the small heat exchange tube 2 passes through the fire tube body 1, a gap is reserved between the outer wall of the small heat exchange tube 2 and the inner wall of the fire tube body 1, so that the circulation of hot fluid is facilitated.

As a technical optimization scheme of the utility model, a plurality of small heat exchange tubes 2 are uniformly distributed on the fire tube body 1. The plurality of small heat exchange tubes 2 are evenly arranged at intervals, so that the upper and lower adjacent small heat exchange tubes are arranged in a cross staggered mode, and the effect of heat exchange between the fluid heat in the fire tube body 1 and the refrigerant in the small heat exchange tubes 2 is better.

The hot fluid in the fire tube body 1 flows, when the fluid passes through a narrow place, the flow speed can be increased, a Venturi effect can be generated, and the fire tube can be understood as a funnel effect. The space occupied by the molecules with high energy in the thermal fluid is larger than that of the molecules with relatively low energy, the molecules with low energy pass through the narrow place, the molecules with high energy are relatively lagged, and the lagged high energy molecules transfer the heat energy into the refrigerant in the small heat exchange tube 2 through the metal fire tube body 1, so that the heat exchange effect of the fire tube is realized. By designing a plurality of small heat exchange tubes 2 which are crossed at 90 degrees, a series of continuous funnels are formed, the heat fluid passes through each stage, venturi effect is generated, the heat conversion efficiency is improved, and the heat exchange efficiency is higher as the flow speed is faster. Compared with the traditional direct heat exchange fire tube, the heat exchange efficiency is much higher under the same heat exchange area. The hot fluid flows in the pipe, a venturi funnel effect is generated, meanwhile, vortex flow does not generate to increase wind resistance, and the venturi effect can convert part of fluid kinetic energy into heat energy.

The preferred embodiments of the utility model disclosed above are intended only to assist in the explanation of the utility model. The preferred embodiments are not exhaustive or to limit the utility model to the precise form disclosed. Obviously, many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the utility model and the practical application, to thereby enable others skilled in the art to best understand and utilize the utility model.
