Abstract
The utility model discloses an internal thread heat exchange pipe, including the heat transfer body, be provided with the thread on the inner tube face of heat transfer body there is at least one side thread the both sides of thread interval shaping respectively, are close to be formed with screw thread form slot between the side thread of thread and the thread and between two adjacent side threads. The utility model has the advantages of the heat transfer area of the inner tube face of heat exchange tube has been increased effectively for the heat exchange coefficient of evaporation and condensation obtains great promotion, has increased single -funnel heat transfer ability, thereby has makeed heat exchanger and indirect heating equipment's the corresponding reduction of volume, and the consumptive material is corresponding reduction also, has realized energy saving and consumption reduction's target.
Description
Technical field
The utility model relates to heat exchanger parts technical field, particularly relates to a kind of internal thread heat exchanger tube.
Background technology
The refrigeration air-conditioner such as domestic air conditioning, air conditioning for automobiles carries out work mainly through heat exchanger, and heat exchanger tube is the critical piece of heat exchanger.The heat exchanger tube of prior art has light pipe and finned tube etc., finned tube by increasing fin in heat exchange tube or outside pipe, the contact area of heat exchanger tube and heat transferring medium is increased with this, improve the heat exchange efficiency of heat exchanger tube to a certain extent, but fin is generally connected on heat exchanger tube by welding or rolling mode, produce heating comparatively to bother, cost is higher.In addition, also having extrudedly on the inner tube surface of heat exchanger tube has internal thread, and increase the contact area of heat exchanger tube and heat transferring medium and heat transferring medium with this, this also makes heat exchanger tube improve heat exchange efficiency to a certain extent, but the intraductal heat exchange effect of existing internal thread heat exchanger tube is still not enough.For this reason, applicant carried out useful exploration and trial, have found result of the above problems, technical scheme described below produces under this background.
Utility model content
Technical problem to be solved in the utility model: there is the undesirable problem of intraductal heat exchange effect for existing internal thread heat exchanger tube and the internal thread heat exchanger tube that a kind of intraductal heat exchange is effective, effectively can improve single tube exchange capability of heat is provided.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of internal thread heat exchanger tube, comprise heat exchange tube body, the inner tube surface of described heat exchange tube body is provided with thread, it is characterized in that, in the both sides of described thread, interval forms at least side thread respectively, is formed with a screw-like channels near between the side thread and thread of described thread and between two adjacent side threads.
In a preferred embodiment of the present utility model, the head of described thread and the head of every side thread are wedge angle, and the bottom of each screw-like channels is for falling wedge angle.
In a preferred embodiment of the present utility model, the head of described thread and the head of every side thread are arc surface, and the bottom of each screw-like channels is arc surface.
Owing to have employed technical scheme as above, the beneficial effects of the utility model are: form at least side thread in interval respectively by the both sides at thread, and be formed with a screw-like channels near between the side thread and thread of thread and between two adjacent side threads, effectively increase the heat exchange area of the inner tube surface of heat exchanger tube, the coefficient of heat transfer of evaporation and condensation is highly improved, add the exchange capability of heat of single tube, thus make the corresponding minimizing of the volume of heat exchanger and heat transmission equipment, consumptive material is corresponding minimizing also, achieve energy-saving and cost-reducing target.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of embodiment of the present utility model.
Fig. 2 is the structural representation of another kind of embodiment of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1, what provide in figure is a kind of internal thread heat exchanger tube, comprise heat exchange tube body 100, the inner tube surface of heat exchange tube body 100 is provided with thread 110, form side thread 120a, 120b in the both sides of thread 110 respectively, between side thread 120a, 120b and thread 110, form a screw-like channels 130a, 130b.Certainly, the both sides of thread 110 can form multiple sides thread in interval respectively, and except being formed except screw-like channels between the side thread and thread of thread, also screw-like channels is formed between two adjacent side threads, so the quantity of side thread 120a, 120b of thread 100 both sides is not limited to the data in this enforcement, it should require according to the heat transfer effect of heat exchanger tube and processes and determine.
The head 111 of thread 110 and head 121a, 121b of side thread 120a, 120b are wedge angle, the bottom of side thread 120a, 120b for falling wedge angle, as shown in Figure 1.In addition, the head 111 of thread 110 and the head 121a, 121 of side thread 120a, 120b are arc surface, and the bottom of side thread 120a, 120b is arc surface, as shown in Figure 2.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
