Abstract

The utility model provides a heat-transferring pipe for a highly effective heat exchanger. The heat-transferring pipe for a highly effective heat exchanger is composed of an outer heat-transferring fin, a heat-transferring pipe, an inner heat-transferring fin and a supporting pipe. Compared with other types of heat-transferring pipes, under the condition of the same cross-sectional area, the heat-absorbing area (or heat-dissipating area) of the heat-transferring pipe made through the invention can be increased by times. Therefore, the heat exchanger made through the heat-transferring pipe not only has high heat-transferring efficiency but also has small volume. The technique can be extensively used in various aspects, such as the chemical industry, electric power, machinery, domestic appliances, such as instantaneous water heaters, air conditioners, etc.

Description

The efficient heat exchanger heat-transfer pipe

The present invention relates to a kind of heat exchanger heat-transfer pipe.

Existing heat exchanger generally all is to make with metal with heat-transfer pipe, there are many thermofins the outside, to increase heat transfer area, in order to strengthen heat-transfer effect, improve heat transfer efficiency, method commonly used utilize exactly increase heat-transfer pipe length or increase the heat-transfer pipe diameter or and fin is processed into corrugated, zigzag or other type shape, to strengthen heat transfer area, though can improving heat transfer efficiency, this method can cause equipment benzene heavy, waste many raw material, effect still is not ideal enough, and another method is to change heat transfer medium, reach the quickening heat transfer rate, improve the heat transfer efficiency purpose, but this method is difficult for being used in as this field, aspect of high-temperature high-pressure boiler with as air-conditioner these small diameter pipeline aspects such as fast water heater and car coolers." 10 years achievement exhibitions of Chinese patent " the 251st page of this this book and other pages have just introduced the various designs of enhanced heat transfer component and the efficient heat exchanger that utilizes the superconduction hot material to make, and " Chinese patent newspaper " introduced on August 21st, 96 the 4th edition and utilized the method that changes medium to improve the method for heat transfer rate and efficient, but these methods all have certain limitation, and utilize this patent just can overcome above-mentioned weak point, if utilize the present invention not only can improve heat exchanger effectiveness as Chinese patent ZL95202122.6 and Chinese patent ZL95201816.0, the shower volume is reduced, and can make hair-dryer, the hot blast temperature of outlets such as baker also can improve greatly.

The purpose of this invention is to provide the heat-transfer pipe that a kind of efficient heat exchanger is used, it is the heat conduction efficiency height not only, and volume is little, and can be used in various heat exchanger occasions.

The present invention is achieved like this: increased stay pipe and interior thermofin in the middle of known heat-transfer pipe, interior thermofin can be processed into different shape according to the appointed condition of producer, and outer heat transfer fin can be processed into known corrugated, zigzag or concavo-convex different shape such as planar are to strengthen heat transfer area, if manufacturer has grasped outer heat transfer fin and the integrated production technology of heat-transfer pipe, must reduce the thermal resistance between outer heat-transfer pipe and the outer heat transfer fin, if manufacturer does not also grasp this technology, also available traditional production technology production, it is big that but thermal resistance is wanted, and reach design and conduct heat and require the fin will be more.Stay pipe and interior thermofin are owing to be in heat-transfer pipe, it is little to bear relative pressure, therefore can make of the material such as the aluminum of easy calendering, just interior stay pipe and interior thermofin are integrated, to reduce thermal resistance, improve heat conduction efficiency, certainly also can produce respectively and be squeezed into one then, though thermal resistance can be big, also do not hinder use, and this back kind method material selects face big.Optimal method is outer heat transfer fin, heat-transfer pipe, and interior thermofin, stay pipe is produced once, and once-forming is in the hope of reaching best heat-transfer effect.

The present invention had been because just increasing interior thermofin in original heat exchanger tube the inside, and stay pipe is therefore simple in structure, very easily puts into production.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is front view of the present utility model and left view.

Describe in detail according to details and the working condition that the utility model proposes according to Fig. 1 below.

Thermofin 4. stay pipes in 1. outer heat transfer fin 2. heat-transfer pipes 3. among the figure

The purpose of this utility model is achieved like this: that establishes that heat-transfer pipe (2) outside flows from left to right is liquid and is thermophore, what flowed from right to left in the inside is gas, so when liquid flows from left to right, the heat that liquid itself carries passes to the inboard of heat-transfer pipe (2) by the outside of outer heat transfer fin (1) and heat-transfer pipe (2), again because interior thermofin (3) and heat-transfer pipe (2) pressure very tight, the heat of heat-transfer pipe (2) just passes to interior thermofin (3) and passes on the stay pipe (4), this moment, gas flowed from right to left, in flow process, GAS ABSORPTION behind the heat of interior thermofin (3) and stay pipe (4) temperature rise, reach the purpose of heat exchange, because it is a lot of and be two-sided heat absorption that the sheet number of interior thermofin (3) can be done, therefore interior thermofin (3) is arranged and do not have interior thermofin (3) heat-transfer effect just to make a world of difference, as calculating by legend and by 1 to 1 size, interior thermofin (3) is arranged and do not have its endotherm area of interior thermofin (3) just to differ 5 times, therefore utilize its effect of the utility model just very obvious.

Along with progress of science and technology, that can further improve heat transfer area again if be reprocessed into thermofin in stay pipe the inside, or and clear-cut without stay pipe but interior thermofin directly be processed into intermesh and the surface be different shape integral body efficient is just higher so.

Claims

1. one by known enhanced type heat-transfer pipe (2), outer heat transfer fin (1), the efficient heat exchanger heat-transfer pipe that interior thermofin (3) and stay pipe (4) are formed is characterized in that: interior thermofin (3) and stay pipe (4) are arranged in the inside of known heat-transfer pipe (2).

2. device according to claim 1 is characterized in that interior thermofin (3) both can link to each other with stay pipe (4), also can not want stay pipe, and by being connected to each other between the interior thermofin (3).

3. device according to claim 1, it is characterized in that can being made of one between heat-transfer pipe (2) and the interior thermofin (3) also can be by tightly being pressed in heat-transfer pipe (2) on the interior thermofin (3) by external force, to reduce resistance to heat.
