Abstract
The utility model discloses a corrosion resistance fin for a microchannel heat exchanger. A transverse wavelet (111) is formed on a corrugated rib plate (11) of an aluminum alloy foil (1) with a continuous corrugated shape. No incision is formed in the corrosion resistance fin, and the corrosion resistance fin is a whole, so that the corrosion resistance fin has high corrosion resistance and long service life; furthermore, air flow can be baffled among the fins, so that the heat exchange time is prolonged, and the heat exchange effect is improved.
Description
Technical field:
The utility model relates to technical field of heat exchangers, more specifically to the used fin of micro-channel heat exchanger.
Background technology:
The copper pipe aluminum fin heat exchanger is adopted in fields such as present domestic freezing and refrigeration, train air-conditioning, automobile air conditioning system more, uses expanding joint process to fit to reach the purpose of heat exchange by copper pipe and aluminium fin.In order to reach the effect of energy-saving and emission-reduction; People have designed micro-channel heat exchanger; The characteristics of microchannel parallel operation are that its heat exchanger tube is flat-shaped and forms hole, a plurality of microchannel, if on the heat exchanger tube of micro-channel heat exchanger, fix common fin, because there is otch in some fin; So corrosion resistance is relatively poor, also then there is the unfavorable shortcoming of heat exchange effect simultaneously.
The utility model content:
The purpose of the utility model is exactly the deficiency to prior art, and provides a kind of micro-channel heat exchanger corrosion-resistant fin, does not have otch above it; Fin is as a whole, good corrosion resistance, long service life; Air-flow can produce baffling between fin simultaneously, prolongs heat-exchange time, improves the heat exchange effect.
The technological solution of the utility model is following:
The corrosion-resistant fin of a kind of micro-channel heat exchanger forms horizontal ripplet being on the ripple floor of continuous undulatory alloy foil.
Form vertical ripplet on the said ripple floor.
Said is that the center is and is symmetrically distributed with horizontal ripplet and vertical ripplet with ripple floor middle part.
The beneficial effect of the utility model is: do not have otch above it, fin is as a whole, good corrosion resistance, and long service life, air-flow can produce baffling between fin simultaneously, prolongs heat-exchange time, improves the heat exchange effect.

Fig. 3 is the B of Fig. 2---the B cutaway view
Fig. 4 is the C of Fig. 2---the C cutaway view
Fig. 5 is the operation principle sketch map of the utility model
Among the figure: 1, be continuous undulatory alloy foil; 11, ripple floor; 111, horizontal ripplet; 112, vertical ripplet.
The specific embodiment:
Embodiment: see shown in Fig. 1 to 4 that the corrosion-resistant fin of a kind of micro-channel heat exchanger forms horizontal ripplet 111 being on the ripple floor 11 of continuous undulatory alloy foil 1.
Form vertical ripplet 112 on the said ripple floor 11.
Said is that the center is and is symmetrically distributed with horizontal ripplet 111 and vertical ripplet 112 with ripple floor 11 middle parts.
Operation principle: see shown in Figure 5ly, air-flow is when being continuous undulatory alloy foil 1, run into ripplet 111 can produce as shown in Figure 5 in the baffling shown in the arrow, prolong heat-exchange time, improve the heat exchange effect.
Do not have otch above being continuous undulatory alloy foil 1, fin is as a whole, good corrosion resistance, long service life.
