Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
It should be noted that, when element is called as " being fixed on " or " being arranged at " another element, it can directly on another element or may there is centering elements simultaneously.When an element is known as " being connected to " another element, it can be directly connected to another element or may there is centering elements simultaneously.
Also it should be noted that, the orientation term such as left and right, upper and lower in the present embodiment, is only relative concept or be reference with the normal operating condition of product each other, and should not be regarded as have restrictive.
With reference to Fig. 1, the heat exchanger that the utility model embodiment provides, be applied to air conditioner room unit, it comprises horizontally disposed upper header 100, lower header 200, some fins 400 being connected to the flat tube 300 between header 100 and lower header 200 and being located on each flat tube 300.Composition graphs 2, above-mentioned heat exchanger has windward side 500 and leeward side 600, and wherein, windward side 500 is positioned on rear side of heat exchanger, and leeward side 600 is positioned on front side of heat exchanger, and wind flows out by front side of heat exchanger after flat tube 300 and fin 400 bottom horizontal flow sheet by rear side of heat exchanger.In the present embodiment, flat tube 300 is obliquely installed, and has angle, and upper header 100 is connected with a noise reduction fluid reservoir 700 between itself and the distinguished and admirable air intake direction of windward side 500.
In the present embodiment, because flat tube 300 is obliquely installed relative to air intake direction, therefore increase the area of flat tube 300 windward side, improve heat exchange efficiency, avoid wind directly to blow fin 400 simultaneously, reduce wind noise; This heat exchanger has noise reduction fluid reservoir 700 simultaneously, and the sound deadening of noise reduction fluid reservoir 700 reduces refrigerant flowing and vaporization sound greatly, improves the tonequality of the air conditioner room unit using this heat exchanger; And when heating refrigerant some be stored in noise reduction fluid reservoir 700, realize the circulating refrigerant amount in adjustment refrigeration system, improve the heat exchange efficiency of heat exchanger, effective heating effect improving complete machine refrigeration system, the heat exchanger therefore in the present embodiment has compact conformation, cost is low, recovery is convenient, draining is smooth and easy and heat exchange efficiency advantages of higher.
With reference to Fig. 2, if the scope that angle is α, α meets: 0 ° of < α < 90 °.When α is 0 °, flat tube 300 is consistent with windward side 500 air intake direction, and the front face area now on flat tube 300 is minimum; When α is 90 °, flat tube 300 is vertical with windward side 500 air intake direction, although now the front face area of flat tube 300 is maximum, when arranging like this, together adjacent between adjacent flat tube 300, stops wind flow.Therefore in the present embodiment, preferably, the scope of angle α meets: 0 ° of < α < 45 °, reduces windage again like this while guarantee heat exchanger improves front face area.Within the scope of this, α can adjust according to the air conditioner room unit actual demand air quantity and heat exchange area using this heat exchanger.
With reference to Fig. 3, in the present embodiment, noise reduction fluid reservoir 700 comprises tank body 710 and by the lower tube connector 720 stretched out bottom tank body 710, the end of upper header 100 is stretched in tank body 710 by the top of tank body 710, and upper header 100 tube wall stretched in tank body 710 is provided with some bloops 110.Like this, the two ends of flat tube 300 are communicated with upper header 100, lower header 200 respectively, and upper header 100 is communicated with noise reduction fluid reservoir 700, then connect into an entirety through lower tube connector 720.
During kind of refrigeration cycle, refrigerant enters flat tube 300 by lower header 200, flows out after pervaporation from upper header 100, and through tank body 710, is then flowed out by lower tube connector 720; Heat circulation time, refrigerant enters tank body 710 first at the refrigerant of its bottom storage certain capacity by upper header 100, and then enter flat tube 300 and carry out heat exchange, whole process effectively reduces refrigerant circulation, improve heat exchange efficiency and refrigeration system pressure, further increase refrigeration system Energy Efficiency Ratio.Refrigeration with heat in circulation, bloop 110 can absorb noise that in header 100, refrigerant produces with tube wall because of flow velocity and refrigerant and to vaporize noise, thus comfortableness when improve air conditioner room unit use.
Certainly, also directly upper tube connector (not shown) can be set in noise reduction fluid reservoir 700 top, the top of upper tube connector is stretched out tank body 710 and is connected with the end of upper header 100, the bottom of upper tube connector is positioned at tank body 710, and above-mentioned bloop 110 is positioned at the bottom of tube connector.Adopt this structure, the object of noise reduction and liquid storage can be reached too.
The utility model additionally provides a kind of air conditioner room unit, and it includes above-mentioned heat exchanger.Above-mentioned heat exchanger structure is compact, cost is low, recovery is convenient, is applied to air conditioner room unit, effectively reduces system running pressure, improve refrigeration system Energy Efficiency Ratio, meanwhile, flowing and the vaporization sound of refrigerant have also been obtained obvious improvement, improve comfortableness and the Consumer's Experience of air-conditioning.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
