Abstract
An outdoor wide/narrow sheet and fin-like heat exchanger of an air source heat pump of the utility model relates to the structure of outdoor fin-like heat exchangers, such as cold hot water units which use air as low order heat source, unit type heat pump type air conditioners, roof type heat pump air conditioner units, heat pump type indoor air conditioners, etc. The heat exchanger of the utility model is composed of a heat exchange tube (4) and fins (3). The fins (3) are fixed on the outer wall of the heat exchange tube (4). The distance (2) of the fins (3) at one side of the air outlet of the heat exchanger is smaller than the distance (1) of the fins (3) at one side of the air inlet of the heat exchanger. The utility model increases the distance of the fins at one side of the air inlet of the outdoor fin-like heat exchanger. The outdoor wide/narrow sheet and fin-like heat exchanger of an air source heat pump effectively relieves the blockage between the fins by frost in winter. The interval of defrosting for twice is prolonged. The times for defrosting are decreased. The energy consumption is decreased. The influence for the heat pump heating capacity is decreased. The working efficiency of the heat exchanger is enhanced.
Description
Technical field:
The utility model relates to the air structure of outdoor finned (rib-type) heat exchanger that is (hereinafter to be referred as air source heat pumps) such as the hot and cold water unit (claiming air-cooled heat pump water chiller-heater units again) of low level heat energy, modular heat pump type air conditioner machine, roof type heat pump type air conditioner unit, pump type heat room air conditioners.
Background technology:
The fin pitch of fins of outdoor finned (rib-type) heat exchanger of existing air source heat pump all is unified, and narrow.When operation of heat pump in the winter time, outdoor heat exchanger is because frosting makes the circulation of air section between fin more and more little, even blocked fully, causes by the air mass flow of finned heat exchanger more and more for a short time, even approaches zero; Cause the heating capacity of air source heat pump sharply to descend at last.For this reason, need often outdoor heat exchanger to be defrosted.During Defrost operation, cause not heat supply of air source heat pump or time-out to heat (its influence is relevant with Defrost method).According to actual observation and theory analysis, frost layer major sedimentary is at the front row of finned heat exchanger (1～3 comb that refers to heat exchanger air intake one side, total row's number on heat exchanger is decided), when the fin gap at front row is stopped up by the frost layer, even the frost layer is very thin on back row's (several combs that refer to heat exchanger air-out one side) the fin, the air mass flow by heat exchanger is reduced, even be close to zero, thereby cause the air source heat pump heating capacity to descend, and must defrost.
The utility model content:
The purpose of this utility model is the outdoor width pitch of fins of a kind of air source heat pump of a development finned heat exchanger, it has between the fin of delaying is stopped up by frost winter, prolongs the blanking time of twice defrosting, reduces the defrosting number of times, thereby the minimizing energy consumption reduces the characteristics that defrosting impacts the heat pump heating capacity.Heat exchanger of the present utility model is made up of heat exchanger tube 4, fin 3, and fin 3 is fixed on the outer wall of heat exchanger tube 4, and the spacing 2 of the fin 3 of heat exchanger air outlet slit one side is less than the spacing 1 of the fin 3 of heat exchanger air intlet one side.The utility model has increased the spacing of outdoor finned heat exchanger air intlet one side fin, delayed effectively between fin to be stopped up by frost winter, prolonged the blanking time of twice defrosting, reduced the number of times of defrosting, thereby reduced energy consumption, reduced the influence of defrosting, improved the operating efficiency of heat exchanger the heat pump heating capacity.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, Fig. 2 be the A of Fig. 1 to view, Fig. 3 be the B of Fig. 1 to view, Fig. 4 is that the C of Fig. 1 is to view.
The specific embodiment:
The specific embodiment one: (referring to Fig. 1-Fig. 4) heat exchanger of present embodiment is made up of heat exchanger tube 4, fin 3, fin 3 is fixed on the outer wall of heat exchanger tube 4, and the spacing 2 of the fin 3 of heat exchanger air outlet slit one side is less than the spacing 1 of the fin 3 of heat exchanger air intlet one side.The spacing 1 of the fin 3 of heat exchanger air intlet one side is 2: 0.5～2: 1.5 with the gap ratio of the spacing 2 of the fin 3 of heat exchanger air outlet slit one side.The spacing 1 of the fin 3 of heat exchanger air intlet one side is 2: 1 with the better spacing ratio of the spacing 2 of the fin 3 of heat exchanger air outlet slit one side.
The specific embodiment two: the outdoor width pitch of fins of the air source heat pump finned heat exchanger of (referring to Fig. 1, Fig. 4) present embodiment is formed at the air-flow direction tandem compound apart from part (arrow gauge is apart from heat exchanger) by wide pitch of fins part (wide pitch of fins heat exchanger) and arrow gauge.Wide pitch of fins heat exchanger is positioned at the air intake side, and arrow gauge is positioned at the air outlet slit side apart from heat exchanger.Wide pitch of fins heat exchanger is arranged number at the pipe of air-flow direction row number on the house steward of width pitch of fins finned heat exchanger and is decided, and gets one～three row.
Claims (3)
