The specific embodiment
Referring to figs. 1 through Figure 12, a kind of indoor heating of the present invention comprises with heat-exchange device
Comprise housing 1, heat exchange module group unit 2 and fan 3, fan 3 is arranged at the rear end of housing 1, and to blow auxiliary heat exchange module group unit 2 heat radiations of cold wind, heat exchange module group unit 2 is arranged at the front end of housing 1, and it comprises:
Bend to snakelike snakelike micropore flat tube or be arranged in parallel and form the micropore flat tube group that micropore flat tube 21 that the curved shape of snake is communicated with is formed by some, be provided with fin 22 between adjacent two micropore flat tubes 21 between adjacent two straight lengths in the snakelike micropore flat tube or in the micropore flat tube group, in this specific embodiment, micropore flat tube 21 in described fin 22 and snakelike micropore flat tube or the micropore flat tube group adopts and is welded to connect, certainly also can be one-body molded between fin 22 and the flat tube, namely form fin 22 by cut out blocks of plates on the both sides of flat tube; Be filled with working medium in described snakelike micropore flat tube or the micropore flat tube group;
Coupling assembling, comprise communicating pipe 26 and union elbow 27, described communicating pipe 26, snakelike micropore flat tube and micropore flat tube 21 all are arranged to form multichannel structure by a plurality of micropores, preferably, a plurality of micropores are yi word pattern and arrange, in concrete application process, the equivalent diameter of each micropore and geometry all can be according to the settings that needs of working medium feature and exchange characteristics; Communicating pipes 26, two ends were by the union elbow 27 formation enclosure space that is connected with the two ends of snakelike micropore flat tube or micropore flat tube group, working medium circulates in enclosure space, namely when heat exchange module group unit 2 is snakelike micropore flat tube configuration, snakelike micropore flat tube two ends with communicating pipes 26 two ends be connected by union elbow 27 respectively; When heat exchange module group unit 2 was micropore flat tube group structure, the termination of two micropore flat tubes 21 of micropore flat tube group outermost end was connected by union elbow 27 with pipe joint respectively; And
Preferably, with reference to Figure 10, described fan 3 employing air quantity are big, noise is low, the cross flow fan of compact conformation, for the cold wind that fan 3 is blowed spreads all over heat exchange module group unit 2, cross flow fan is installed on the lower end of housing 1, described housing 1 corresponding fan 3 is provided with air inlet 11, and be provided with the front shroud 12 that is positioned at heat exchange module group unit 2 the place aheads, for preventing child's contact heat-exchanging module group unit 2 and scald, prevent that dust from entering heat exchange module group unit 2 that front shroud 12 is provided with the venthole that heat sheds of being convenient to of a plurality of criss-cross arrangements.In addition, heat exchange module group unit 2 of the present invention not only is defined as one, can be provided with several, each heat exchange module group unit 2 forms an enclosure space, has the ability that works alone, improve heat exchange efficiency with this, it should be noted that the combination of heat exchange module group unit 2 can be according to the tolerance band design alternative of bulk; The working medium characteristic of each heat exchange module group unit 2 and filling rate can be according to selecting with the heat flow rate per unit area Environment Design in space of living in.
Described micropore flat tube group comprises the upper and lower collector 23,24 that be arranged in parallel, each micropore flat tube 21 of micropore flat tube group places between the upper and lower collector 23,24 and its end is connected with upper and lower collector 23,24, upper and lower collector 23, corresponding per two adjacent micropore flat tubes 21 is connected with dividing plate 25 in 24, and the dividing plate 25 in the upper and lower collector 23,24 is staggered, makes the micropore flat tube 21 of micropore flat tube group form the structure that the curved shape of snake is communicated with.
Because heat exchange module group unit 2 is very fast near the one side cooling that cold wind directly cools off, and another side is because wind-warm syndrome has raising, intensity of cooling reduces relatively, so working medium is non-uniform temperature in enclosure space, reduced the heat exchange effect, for addressing this problem, described union elbow 27 is provided with two connection holes 271 that connect, have at least a connection hole 271 to be provided with the catch 272 that the part micropore of connected heat exchange module group unit 2 and/or communicating pipe 26 is blocked to improve uniform temperature in described two union elbows 27, and enclosure space form the closed-loop path all the time.As: when adopting a union elbow 27 to block, with reference to Figure 11, this union elbow 27 blocks the part micropore of connected snakelike micropore flat tube or micropore flat tube 21, part micropore with connected communicating pipe 26 blocks simultaneously, and two connection holes 271 of this union elbow 27 are in the state of perforation all the time, and namely enclosure space forms the closed-loop path all the time; When adopting two union elbows 27 to block, with reference to Figure 12, one of them union elbow 27 blocks connected snakelike micropore flat tube or the part micropore of micropore flat tube 21 or communicating pipe 26, another union elbow 27 blocks connected snakelike micropore flat tube or the part micropore of micropore flat tube 21 or communicating pipe 26 simultaneously, and the two ends of communicating pipe 26 are in the state of perforation all the time with heat exchange module group unit 2, and namely enclosure space forms closed-loop path etc. all the time.The present invention blocks by the passage with the part micropore, make the working medium of clogged passage reflux, and by upper and lower collector 23,24 or union elbow 27 constantly mix, shunt with the working medium in other passages, thereby realize to improve the purpose of uniform temperature and heat exchange efficiency.
Similarly, described upper and lower collector 23,24 also can arrange choke structure, it is the block assembly that some obstruction micropore flat tube 21 part micropores are set in upper header and/or the lower collector pipe, each block assembly places between adjacent two dividing plates 25 on every collector, and comprises first block and/or second block; First block blocks the part micropore of one of them the micropore flat tube 21 between adjacent two dividing plates 25, and second block blocks the part micropore of another micropore flat tube 21 between adjacent two dividing plates 25, and enclosure space forms the closed-loop path all the time.
Preferably, described communicating pipe 26, snakelike micropore flat tube and micropore flat tube 21 adopt the organic material of aluminium alloy or good heat conductivity to make; Such material does not have tangible pin hole in 500 times of high-power microscope downward views, can keep air-tightness and watertightness under high temperature, the high pressure.
The loading of described working medium is 30% ~ 70%, and at this moment, the heat that working medium absorbs electric heater evaporates formation gas and bubble easily in whole enclosure space, and the two-phase pulsating that forms the mixing of gaseous state and liquid two states thus flows.
The loading of described working medium is 100%, at this moment, because volume can not become greatly behind the heat of working medium absorption electric heater, can only form liquid single-phase pulsating and flow.
Preferably, described working medium can be formed by one-component or some combination of components; Some components can form azeotropic point or maintenance boiling point separately.Especially, when working medium was made up of some components and keep separately boiling point, working medium formed turbulent flow in enclosure space, and it is fast to conduct heat, excellent in heat dissipation effect.
