Abstract
The utility model discloses a multi-channel film which is mainly composed of film bodies and a plurality of channels communicated with the film bodies, wherein the film bodies and the plurality of channels are made of non-metal materials. The plurality of channels are a series of channels which are arranged in parallel, the film bodies and the plurality of channels are integrated in a melted mode and form a sheet shape having different lengths and different widths, or are made into a cylinder, and alternatively, a plurality of layers of film bodies are overlaid and combined into a whole. The multi-channel film can directly serve as a plastic film of agricultural crops, and not only can serve as a greenhouse cover film, but also can absorb solar energy to store heat through the fact that heat adsorption media are led into the multi-channel film. When heat preservation is needed, the low-heat-conduction media are led to the multi-channel film or the multi-channel film is vacuumed to play a role of heat-preservation materials. The multi-channel film can be further used in water ground source pump and energy storage sites and other sites of heat exchange among different fluid, and has the advantages of being large in heat-exchanging area, convenient to install and construct, and the like.
Description
Technical field
The utility model relates to a kind of heat exchanger, especially, relate to a kind of for solar energy heating heat exchanger, the hot equipment of water earth source heat pump cold-storage, humiture independence control field as radiation recuperator, the multichannel film of heat exchange between snow melting equipment and industrial fluids.
Background technology
At present, at high yield and the annual planting plants of agriculture field for the acquisition crops, the general plastic sheeting that adopts is as the covering of crops booth, this film can absorb sunlight by day, but when weather is lowered the temperature at night, because film thermal insulating is poor, can not guarantee the booth uniform temperature, in the temperature difference large period, this kind plastic film shed heat-insulating property is also limited especially, need to realize insulation by other facilities.At sun grace time, booth also needs sunshade or ventilation and heat, can not effectively utilize solar energy simultaneously.Carry out the heat exchange occasion at the water earth-source hot-pump system such as soil source, source of sewage, seawater, river and industrial fluids in addition, adopt such as pipe-polishing heat exchanger, exist floor space large, easy cleaning not, installation difficulty is larger, overhauls the large shortcoming of difficulty.The coil pipe that adopts in soil, the hot field of water cold-storage especially exists the accumulation of energy rate low, the characteristics that cost is high.Snow melt in winter technology mainly adopts the technology such as electrical heating and snow-melting agent to remove the snow at present, has the problem of waste electric power resource and contaminated environment.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of multichannel film is provided.
In order to reach the purpose of above-mentioned utility model, the technical solution of the utility model realizes as follows: a kind of multichannel film, it mainly is comprised of film and a plurality of passages that are attached thereto.
Further, described film and a plurality of passages that are attached thereto adopt nonmetallic materials to make, and nonmetallic materials include but not limited to polymer composite and modification heat-conductive composite material.
Further, described a plurality of passages are a rule passage, and channel cross-section is shaped as circle, ellipse or other shapes, the sectional dimension of passage can also can be meter level by micron order, multichannel is for being arranged in parallel, and spacing is changeable between the passage, also can be mutually adjacent.
Further, described film and a plurality of passages that are attached thereto combine together, and melting the body mode can be for multiple, can be for channel middle, top and the bottom or be whole parcel, and film dimensions is big or small different with connected mode according to multichannel, and different thickness are arranged.
Further, described film and a plurality of passages that are attached thereto form the sheet of a different length and width or are rolled into cylinder, or can which floor film stack be combined into one.
The beneficial effects of the utility model are: adopt this kind multichannel film can realize that on the crops booth plastic sheeting covering and solar energy heating are two-in-one, can effectively regulate greenhouse temperature, simultaneously unnecessary solar energy is stored, with the solar energy maximum using, also realize the automation control temperature action of booth.This multichannel film is used for soil, water and other phase-change material thermal storage equipments, can realizes that the unit volume accumulation of energy is high, simple and reliable characteristics are installed.This multichannel film is used for snow melt road occasion can realizes summer in the soil accumulation of heat, be used for snow melt with the Heat in Soil amount winter, realizes the energy-conserving and environment-protective purpose.This multichannel film is used for other fluid heat exchanger occasions, has the large characteristics of heat exchanger unit mass heat exchange area, and anticorrosion, easy to install, save installing space, more be not subject to damage, this heat exchanger also is convenient to clean.

The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing, it is more obvious that the purpose of this utility model and effect will become.
Multichannel film of the present utility model mainly is comprised of film 2 and several passages 1 that are attached thereto.
Described film 2 and be attached thereto passage 1 all adopt nonmetallic materials to make, nonmetallic materials include but not limited to polymer composite and modification heat-conductive composite material.
Shown in Fig. 1,2,3,4,5, described passage 1 is a rule passage, and passage 1 cross sectional shape can be circular, oval or other shapes; The sectional dimension of passage 1 can be micron order, also can be meter level; Passage 1 is for being arranged in parallel, and spacing is changeable between the passage 1, also can be mutually adjacent.Film 2 combines together with passage 1, and the mode that combines together has multiple, and with passage 1 middle part, upper and lower part or be whole parcel passage 1, film 2 sizes are big or small different with the mode of combining together according to passage 1, and different thickness are arranged.
As shown in Figure 5, described multichannel film can be made into cylinder, and barrel bore is changeable.
As shown in Figure 6, which floor film stack described multichannel film can be combined into one to use.
As shown in Figure 7, described film 2 and be attached thereto different length of formation of passage 1 and the sheet of width.
As shown in Figure 8, described multichannel film can also can be storage heater with the first communicating pipe 3, the second communicating pipe 4, delivery pump 5, heat exchanger 6() form the function that a kind of system wherein realizes solar energy utilization and adjusting.Cover the utility model multichannel film on the crops booth or other sunshines can shine part, and other have than large radiation thermal source part.When the multichannel film needs the transmission thermal source, in multichannel, pass into transparent fluid or form vacuum; When the multichannel film needs the radiation-absorbing thermal source, pass into heat-absorbing medium, when heat-absorbing medium is black, can realize the sunshade effect, circulate; When the multichannel film need to be incubated institute's covering, the multichannel film is evacuated or passes into low heat-conducting medium, realize heat insulation effect; By delivery pump with thermal source by the multichannel film transfer in heat exchanger 6, also heat energy storage can be transferred to and carry out the heat supply function in the multichannel film.Heat exchanger 6 can be multichannel film or other pattern heat exchangers, and it is placed in soil, water body, other fluids or the phase-change material.
