Description

TECHNICAL FIELD

[0001] The utility model belongs to heat pipe heat exchange equipment technical field, especially relate to a kind of inner eddy current type cold runner vacuum heat pipe and the heat exchanger formed by it. BACKGROUND

[0002] At present, the water side part of heat pipe is generally divided into water tank type or sleeve type. The traditional water tank type water side structure has low pressure resistance, low water speed, poor heat exchange efficiency, low water side temperature, and the like. The water side sleeve structure has many welding points, difficult processing technology, and difficult maintenance after welding problems.

[0003] A patent with the application number CN201921877696.0 discloses a flue gas waste heat recovery device, which comprises a flue connected with a boiler at one end, a dust collector connected with the flue, a vacuum tube installed in the flue, the vacuum tube having a sealed tube shell and being filled with evaporation medium, the lower and upper sections of the vacuum tube being respectively arranged in the flue and a water tank filled with water, the upper part of the water tank being connected with the inlet of a circulating pump through a pipeline provided with an electric control valve I, the outlet of the circulating pump being connected with the inlet of a low-pressure heater through a pipeline, the outlet of the low-pressure heater being connected with the lower part of the water tank through a pipeline provided with an electric control valve III, the top of the water tank being further connected with an expansion tank through a pipeline, liquid level sensors I and II being respectively arranged on the water tank and the expansion tank, the liquid level sensors I and II being electrically connected with a controller, and the electric control valve III being controlled by the controller. The utility model mainly provides a scheme for solving the problem of water pipe leakage of a conventional flue gas-water heat exchanger affecting the safe operation of subsequent equipment. However, the scheme has the following problems: (1) the water tank structure has limited pressure-bearing capacity and cannot be applied to large coal-fired units; (2) the water flow speed of the water tank structure is low, and the heat exchange effect with the heat pipe base pipe is poor. To solve the problems of pressure-bearing and poor heat exchange effect, a patent with the application number CN202121269097.8 discloses a baffle for a pressure-bearing and pressure-resistant heat pipe heat exchanger water tank, which comprises a pressure-bearing and pressure-resistant water tank cylinder and a heat pipe, the cold side of the heat pipe being located in the pressure-bearing and pressure-resistant water tank cylinder, a plurality of baffles being arranged in the pressure-bearing and pressure-resistant water tank cylinder, and the condensate water directly introduced into the pressure-bearing and pressure-resistant water tank cylinder forming a cross-flow or counter-flow heat exchange flow form with the flue gas under the action of the baffles. After using the pressure-resistant water tank, the required equipment of the heat pipe heat exchanger system is reduced, the flue gas flow direction and the condensate water flow direction are designed as a cross-flow or counter-flow type through the further improvement of the baffles in the water tank, the logarithmic mean temperature difference is improved, the heat exchange efficiency of the heat pipe module is improved, the heat exchange area is reduced, the system safety is further improved, and the investment cost is reduced after optimizing the system process, reducing the redundant equipment of the system, and simplifying the system process. Although the scheme improves the heat exchange efficiency to some extent, it has the following problems: too many baffles, large welding workload, and small gap between the baffles and the base pipe, which cannot be handled. In addition, the side cylinder water tank structure and the top tension structure cannot solve the problem of the downward cracking of the welding between the top and bottom plates of the water tank and the cylinder under high water pressure.A patent with the application number CN202021421785.7 discloses a flue gas heat extractor, which comprises a heat exchange module. The heat exchange module comprises multiple rows of heat exchange pipe assemblies. One row of the heat exchange pipe assemblies comprises multiple heat exchange pipes arranged in sequence along a first direction. One heat exchange pipe assembly comprises one heat pipe and one outer sleeve pipe. A part of each heat pipe is inserted into the corresponding outer sleeve pipe. Both ends of the outer sleeve pipe are closed connected with the heat pipe. Cooling water can flow between the inner wall of the outer sleeve pipe and the outer wall of the corresponding heat pipe. In each row of the heat exchange pipe assemblies, multiple outer sleeve pipes are alternately connected in sequence along the first direction. The heat exchange module of the flue gas heat extractor comprises multiple rows of heat exchange pipe assemblies. The outer sleeve pipes of each row of heat exchange pipe assemblies are alternately connected in sequence. Thus, each row of heat exchange pipe assemblies can form a serpentine labyrinth flow channel. The cooling water in the outer sleeve pipes of adjacent heat exchange pipe assemblies flows in opposite directions. Therefore, the heat exchange capacity can be effectively improved. The patent adopts the form of upper and lower connecting pipes to connect each sleeve pipe with each other. However, in application, if welding between the sleeve pipe and the lower connecting pipe fails, especially if the lower weld fails, it is basically impossible to handle the problem, and the entire row of pipes must be isolated, resulting in the loss of part of the heat exchange area. In addition, in some special applications, the patent also finds that it is difficult to discharge the gas in the sleeve pipe during the starting process, which causes the upper water-side heat exchange surface to be occupied by air, and the heat exchange effect is poor.

[0004] Therefore, due to the structural design problem, the current heat pipe heat exchanger still has problems such as water-side gas retention, and the heat exchange effect is poor. Utility model content
