Abstract
The utility model discloses a flat-plate heat collector with internal screw threads, copper pipes and flow passages, which comprises a box body, wherein a water distribution pipe and a water collection pipe are arranged in the box body, and the inner walls of the water distribution pipe and the water collection pipe are provided with helical diversion trenches. The utility model adopts pipes of which the inner walls are provided with the helical diversion trenches as the water collection pipe and the water distribution pipe. By the helical diversion trenches, water in the pipes forms vortex flow so as to quicken the heat exchange of the water at an outer layer and the center, so that the temperature of the water in the pipes is uniform, the heat capacity of the water is fully utilized, and the heat-exchange efficiency is enhanced. In addition, the probability of scaling in the pipes is also reduced by the vortex flow simultaneously.
Description
Technical field
The utility model relates to a kind of solar water heater, especially a kind of dull and stereotyped inner screw thread copper pipe runner heat collector.
Background technology
Solar water heater solar energy heat-obtaining, environmental protection and energy saving can bring social benefit for country, can bring economic benefit for the user again.Along with the maturation of solar heat absorption techniques, solar water heater is popularized gradually.Dull and stereotyped inner screw thread copper pipe runner heat collector because have advantages such as elegant in appearance, is loved by the people.Be provided with branch, collector pipe in the casing of dull and stereotyped inner screw thread copper pipe runner heat collector, the branch of existing dull and stereotyped inner screw thread copper pipe runner heat collector, the inwall of collector pipe all are smooth, though this water pipe has advantage convenient for production, but water flows therein and during with the outer medium heat exchange of pipe, because water is smooth flow, therefore higher near the coolant-temperature gage of tube wall, lower near the coolant-temperature gage of tube hub, cause the thermal capacitance of water not to be fully utilized, efficient is low.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, can make full use of the thermal capacitance of water, the dull and stereotyped inner screw thread copper pipe runner heat collector that heat exchange efficiency is high.
In order to solve the problems of the technologies described above, the utility model provides a kind of dull and stereotyped inner screw thread copper pipe runner heat collector, comprises casing, is provided with branch, collector pipe in the described casing, and the inwall of described branch, collector pipe is provided with the helical form guiding gutter.
Further, the direction of described guiding gutter is a left-hand screw.
Further, the direction of described guiding gutter is a right-hand screw.
Further, the gradient of described guiding gutter is 5～30 degree.
Further, the gradient of described guiding gutter is 15 degree.
Further, described guiding gutter spacing is 1～10mm.
The utility model adopts inwall the pipe of helical form guiding gutter to be arranged as collection, distributive pipe, the helical form guiding gutter makes the water in the pipe form eddy current, quickens the heat exchange at outer water and center, makes the even water temperature in the pipe, make full use of the thermal capacitance of water, improved heat exchange efficiency.In addition, eddy current also reduces the possibility of in-tube fouling simultaneously.
Description of drawings
Fig. 1 is the cutaway view of the employed pipe of dull and stereotyped inner screw thread copper pipe runner heat collector of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and being implemented, but illustrated embodiment is not as to qualification of the present utility model.
Dull and stereotyped inner screw thread copper pipe runner heat collector of the present utility model comprises casing, is provided with branch, collector pipe in the described casing.Wherein, divide, the structure of collector pipe as shown in Figure 1, minute, be provided with helical form guiding gutter 2 on the inwall of collector pipe 1.The direction of guiding gutter 2 can be to left-hand screw, also can be to right-hand screw.The gradient of guiding gutter 2 (be that the axial angle of the water conservancy diversion direction of guiding gutter and water pipe a) is advisable with 5～30 degree, with 15 degree for good.Distance between the adjacent guiding gutter is advisable with 1～10mm.The helical form guiding gutter makes the water in the pipe form eddy current, quickens the heat exchange at outer water and center, makes the even water temperature in the pipe, has made full use of the thermal capacitance of water, has improved heat exchange efficiency.In addition, eddy current also reduces the possibility of in-tube fouling simultaneously.
The above embodiment is the preferred embodiment that proves absolutely that the utility model is lifted, and protection domain of the present utility model is not limited thereto.Being equal to that those skilled in the art are done on the utility model basis substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
