The specific embodiment

Fig. 1 is the utility model overall structure schematic diagram, mainly comprises the person in charge 1, fin, pipe 4, fixed mount 5 and drip tray 6.The person in charge 1 inner wall surface adopts smooth design, has not only improved the coefficient of refrigeration and heat exchange, also meets thermodynamic (al) conduction principle more.The caliber of being responsible for not only can be used for the fluorine system and also can be used for ammonia system, thereby has improved the service efficiency in space greatly.In addition, the thickness that tube wall is responsible in suitable increase has not only further strengthened the circumference stress of pipe itself, and has improved and be responsible for 1 safety coefficient.Fin mainly is divided into upside fin 2 and downside fin 3, and an end of upside fin 2 and downside fin 3 is arranged at respectively is responsible for 1 upside and downside.Upside fin 2 is connected in vertical direction with the center line of being responsible for 1, and downside fin 3 is the horizontal tangent direction with the person in charge 1 and is connected.Downside fin 3 is relative formula structural design, and the surface of downside fin also is provided with the perforate 7 of blinds chip, and this perforate 7 is structural design mode longitudinally, thereby increases the flow area of air.In addition, in heat transfer process, adopt longitudinal folding louvre blade perforate mode also to meet thermodynamic (al) conduction principle more, can fully play the heat exchange efficiency of fin surface unit area, make fin integral body reach best heat exchange effect.Be responsible for 1 surface and also be provided with pipe 4, the inside of pipe 4 is equipped with electric heating wire (describing among the figure), and the power of electric heating wire is between 20 watts/m～60 watt/m, and is connected with an end of upside fin and downside fin respectively.When the frosting on upside fin and downside fin surface reaches certain thickness, electric heating wire in the pipe 4 can conduct heat according to the instruction of defrosting controller (not describing among the figure), the order of its heat conduction heating still is the pipe-person in charge-fin, thereby the frosting on fin surface can be melted in heat transfer process, further reach the purpose of reasonable defrosting.Because fin adopts the circular-arc main transient mode that is designed to the junction on person in charge surface, thereby strengthen fin and be responsible for surperficial physical dimension, also met the heat exchange principle of fin more; In addition, because the spacing of being separated by between the fin is bigger, its spacing also can be adjusted as required again.If the very thin thickness of fin surface frosting can also adopt manual mode that fin is carried out defrost operation by defrosting tool, thereby reach heat economizing effect.The other end at downside fin 3 also is provided with fixed mount 5 and drip tray 6 successively, and drip tray 6 is connected with the other end of downside fin 3 by fixed mount 5.These drip tray 6 integral body structure that is in the shape of the letter V, the inside of drip tray also are provided with heater wire (describing among the figure).Heater wire can carry out heat treated to the surface of drip tray, make the temperature value on drip tray surface can be greater than the wet value of cool house internal cold air, thereby carry out in the defrosting process on the fin surface, make frosting gradate water under the conduction of heat into liquid state, and during along the surface landing downwards of fin, because the cold air temperature value greater than the temperature value of heat, still can avoid water regelation when also not arriving the drip tray bottom to become white phenomenon to take place.

Fig. 2 is the overall structure schematic diagram after a plurality of evaporimeters are arranged in parallel, and mainly comprises evaporator body, fixed bar 11, catheter 8 and gathers water pond 9.Fixedlying connected with fixed bar 11 in the upper end of upside fin 2, is responsible for 1 and is arranged in the surface of catheter 8, thereby make vaporiser body be fixed in catheter 8 and fixed bar 11 surfaces.Catheter inside is provided with cold-producing medium, and the global shape of catheter is serpentine bend shape comb (not describing among the figure).The downside of drip tray 6 also is provided with and gathers water pond 9, and after the water in the drip tray reached the heap(ed) capacity of water pond, water can be flowed out by the dual-side of drip tray, falls into gathering in the water pond of drip tray downside then, thereby the water after the defrosting is derived through gathering water pond inside.

Fig. 3 is the another kind of connected mode structural representation of the utility model fixed mount and drip tray, mainly comprises fixed mount 5, drip tray 6 and rotating shaft 10.Rotating shaft 10 is arranged at an end of fixed mount 5, and be connected with an end of drip tray 6, one end of drip tray 6 is a centre point with rotating shaft 10, can do maximum angle and be 90 ° left rotation and right rotation, thereby increase the exchange of the inboard hot and cold air of downside fin, also further improved the flow area of fin inner body air.

Fig. 4 is the another kind of example structure schematic diagram of the utility model, mainly comprises the person in charge 1, left side fin 12 and right side fin 13.Left side fin 12 is arranged at respectively with right side fin 13 and is responsible for 1 the left and right sides, and the fin surface still is provided with vertical open-celled structure of blinds chip.Can also increase the quantity of fin as required in the both sides of being responsible for, when improving chill surface, can also improve the coefficient of refrigerating performance of being responsible for outside unit length greatly, and play energy efficient and the effect of saving material.

In sum, the straight muscle cross rib evaporimeter that the utility model provides not only can at utmost increase the heat exchange area of equipment, has reduced the waste of the energy, has improved the refrigerating speed and the refrigerating efficiency of equipment integral body greatly.Because of global design structure and manufacturing process advantages of simple, with short production cycle, cost is low again, the efficient height also is fit to large batch of production, not only can improve refrigeration and thermal conduction effect, can also realize defrosting effect preferably, thereby increase the cleanliness factor of entire system.In addition, the whole employing of the utility model aluminium is main material manufacturing, compares with existing steel cold type pipe, and the thermal conductivity factor of aluminium is 2.9 times of steel, and heat transfer coefficient also is 1.43 times of steel comb; Secondly, when reaching identical heat exchange amount, the weight of aluminum wrapped calandria integral body only is 1/6 of steel comb overall weight, therefore is convenient to more install, and has also increased the safety coefficient when using.In addition, the cold-storage ability of aluminium matter comb and whole cleanliness factor also are better than the steel comb, but also are convenient to regular maintenance and maintenance more, thereby can further improve the service life of aluminum wrapped calandria integral body.

More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
