The combined-type gas-liquid heat tube heat exchanger provided by the utility model has a reasonable structure, adopts the high-intensity characteristic of the outwards-protruding ellipsoidal end surface at the upper end of the casing to enable water flowing in the secondary exchange cavity to have higher pressure and meet the technological requirement, has high heat exchange efficiency because of full contact between water in the secondary exchange cavity and the condensation sections of the heat tubes, and is convenient to assemble and disassemble and convenient for installation and maintenance of the heat tubes as the upper and the lower parts of the casing are mutually fixed through a flange. Therefore, the combined-type gas-liquid heat tube heat exchanger is a practical product convenient for use, installation and maintenance, low in cost and high in heat exchange efficiency.

Description

Combined type solution-air heat exchange of heat pipe

Technical field:

The utility model relates to the exchange heat apparatus field, especially a kind of combined type solution-air heat exchange of heat pipe.

Background technology:

Hot pipe technique is the heat transfer element of a kind of being called " heat pipe " of George Ge Luofo (George Grover) invention of U.S. Los Alamos (Los Alamos) National Laboratory in 1963; It has made full use of the Rapid Thermal hereditary property of heat-conduction principle and refrigeration filling; Be delivered to rapidly outside the thermal source through the heat of heat pipe with thermal objects, its capacity of heat transmission surpasses the capacity of heat transmission of any known metal.Hot pipe technique has been widely used in carrying out the heat energy in recuperation of heat and the comprehensive utilization process process in the industries such as metallurgy, chemical industry, oil refining, boiler, pottery, traffic, light textile, machinery, has obtained remarkable economic efficiency.

Common combined type solution-air heat exchange of heat pipe; As shown in Figure 1; Comprise shell 2, sleeve pipe 3, heat pipe 9 and dividing plate 8, dividing plate is divided into an isolated each other superposed secondary inverting chamber 5 and an inverting chamber 7 that is positioned at the bottom with enclosure, and a plurality of heat pipes are uniformly distributed with and are inlaid on the dividing plate; The evaporator section of heat pipe all is positioned at inverting chamber and the equal coaxial welding of outer surface has fin 10; Treat that recuperated gas gets into from the left side, carry out the exchange successively of heat then with the evaporator section of heat pipe, gas is discharged from the right side after the heat exchange.The condensation segment 4 of heat pipe is positioned at the secondary inverting chamber and outer surface all is set with sleeve pipe 3; Sleeve pipe on each heat pipe condenser section is interconnected and whole two ends are communicated with water inlet and the delivery port that secondary inverting chamber both sides are provided with respectively; Cold water gets into from the lower water inlet of right positions; Through the Gap Flow between sleeve pipe and the condensation segment, take away heat simultaneously, discharge from the higher delivery port of leftward position at last.

In the said structure; Because the water side needs pressure-bearing 0.2～1.6MPa, water must be flowing in the requirement of just satisfying pressure-bearing between sleeve pipe and the condensation segment, but the increase of material certainly will cause the increase of cost; And shell is a welding fabrication; When incrustation scale appears in the condensation segment of heat pipe, can't in time clear up, the long-term use can influence the heat exchange effect.

The utility model content:

The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of rational in infrastructure, heat exchange efficiency is high, be convenient to a kind of combined type solution-air heat exchange of heat pipe of installation and maintenance.

The technical scheme that the utility model is taked is:

A kind of combined type solution-air heat exchange of heat pipe; Comprise shell, heat pipe and dividing plate; Dividing plate is divided into an each other isolated superposed secondary inverting chamber and an inverting chamber that is positioned at the bottom with enclosure, and a plurality of heat pipes are uniformly distributed with and are inlaid in the dividing plate, and the evaporator section of heat pipe all is positioned at inverting chamber and the equal coaxial package of outer surface has fin; It is characterized in that: the columniform condensation segment on said heat pipe top all stretches in the secondary inverting chamber, and the shell upper end is the ellipse head of an outside protrusion.

And said shell is made up of the mutual spiral-lock of upper and lower two parts, interfixes through flange between the two, and the upper surface of said dividing plate is crimped on the lower surface of flange and two parts are isolated each other up and down.

The advantage and the good effect of the utility model are:

The utility model is rational in infrastructure, utilizes the outwards pressure-bearing property characteristics of the ellipsoidal head self of protrusion of shell upper end, makes the glassware for drinking water that passes through in the secondary inverting chamber that higher pressure arranged; Satisfy the requirement of technology, the water in the secondary inverting chamber fully contacts with the condensation segment of heat pipe, and heat exchange efficiency is high; And shell upper and bottom interfix through flange; When opening cleaning during fouling on the heat pipe, be convenient to mounting or dismounting, also be convenient to installation, the maintenance of heat pipe; In sum, this heat exchanger be a kind of easy to use, cost is low, be convenient to installation and maintenance, heat exchange efficiency is high is suitable for practical product.

Fig. 2 is the structural representation of the utility model.

The specific embodiment:

Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit the protection domain of the utility model with following embodiment.

A kind of combined type solution-air heat exchange of heat pipe; As shown in Figure 2; Comprise shell 2, heat pipe 9 and dividing plate 8; Dividing plate is divided into an each other isolated superposed secondary inverting chamber and an inverting chamber that is positioned at the bottom with enclosure, and a plurality of heat pipes are uniformly distributed with and are welded in the dividing plate, and the evaporator section of heat pipe all is positioned at inverting chamber and the equal coaxial package of outer surface has fin 10; The innovation of the utility model is: the columniform condensation segment 4 on said heat pipe top all stretches in the secondary inverting chamber, and the shell upper end is the elliposoidal end face 12 of an outside protrusion.

Because the condensation segment on heat pipe top has been cancelled sleeve pipe, all adopts columniform profile, fully contact with the cold water that gets into from water inlet 6 like this, heat exchange efficiency is high, and has saved 13% material, has reduced production cost.

In the present embodiment, shell is made up of top 2 and the bottom mutual spiral-lock of 15 two parts, interfixes through flange 14 between the two, and the upper surface of dividing plate 8 is welded on the lower surface of flange and an inverting chamber is completely cut off with the secondary inverting chamber each other.

When the utility model uses:

Treat that recuperated gas gets into from an inverting chamber left side; Carry out the exchange of heat for the first time with heat pipe evaporator section; Discharge thus from an inverting chamber then, the medium evaporation back in the heat pipe gets into the condensation segment heat release that is positioned at the secondary inverting chamber simultaneously, and these heats are absorbed by the water that flows that is full of the secondary inverting chamber; Hot water is discharged from the delivery port 1 in secondary inverting chamber left side, can be used for other effect.
