Summary of the invention
The object of the present invention is to provide one can effectively promote heat exchange uniformity, prevent the concave V-type heat-exchanger rig forming dead band bottom heat-exchanger rig.
For reaching this object, the present invention by the following technical solutions:
A kind of heat-exchanger rig with water conservancy diversion projection, comprise heat exchange casing and be arranged on the air exhausting device at described heat exchange casing top, described heat exchange casing comprises front heat exchanger plates and rear heat exchanger plates, and the base plate be arranged between described front heat exchanger plates and rear heat exchanger plates, described base plate is concaved with water conservancy diversion projection.
Wherein, described water conservancy diversion projection is that the inverted V-shape that Open Side Down is protruding.
Wherein, described water conservancy diversion projection is chevron shaped projection.
Wherein, described water conservancy diversion is protruding adopts metal plate material integrated punching shaping with described base plate.
Wherein, the angle between described front heat exchanger plates and rear heat exchanger plates is set to acute angle.
Wherein, be provided with top board between described front heat exchanger plates and the top of rear heat exchanger plates, described top board and described base plate be arranged in parallel, and described top board runs through and is provided with exhaust outlet, and described exhaust outlet internal frame is provided with exhaust fan.
Wherein, the two ends, left and right of described front heat exchanger plates and rear heat exchanger plates are respectively arranged with left deep bead and right deep bead, and described left deep bead is connected with the left end of described top board with described base plate, and described right deep bead is connected with the right-hand member of described top board with described base plate.
Beneficial effect of the present invention: the present invention includes heat exchange casing and be arranged on the air exhausting device at described heat exchange casing top, described heat exchange casing comprises front heat exchanger plates and rear heat exchanger plates, and the base plate be arranged between described front heat exchanger plates and rear heat exchanger plates, described base plate is concaved with water conservancy diversion projection.The setting of water conservancy diversion projection, can make air-flow in the localized hyperthermia flow dead that formed bottom heat-exchanger rig by the convex role of water conservancy diversion, effectively get rid of, and then heat exchange uniformity and heat exchange efficiency are effectively promoted.

Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing 2 to accompanying drawing 4.
A kind of heat-exchanger rig with water conservancy diversion projection, comprise heat exchange casing and be arranged on the air exhausting device at heat exchange casing top, heat exchange casing comprises front heat exchanger plates 3 and rear heat exchanger plates 4, and is arranged at the base plate 5 between front heat exchanger plates 3 and rear heat exchanger plates 4, and base plate 5 is concaved with water conservancy diversion projection.
Preferred further, water conservancy diversion projection is the inverted V-shape projection 1 that Open Side Down.
Preferred further, water conservancy diversion projection is chevron shaped protruding 2.
Preferred further, water conservancy diversion is protruding adopts metal plate material integrated punching shaping with base plate 5.
Preferred further, angle between front heat exchanger plates 3 and rear heat exchanger plates 4 is set to acute angle, top board 6 is provided with between front heat exchanger plates 3 and the top of rear heat exchanger plates 4, top board 6 and base plate 5 be arranged in parallel, and top board 6 runs through and is provided with exhaust outlet, exhaust outlet internal frame is provided with exhaust fan 7, and the two ends, left and right of front heat exchanger plates 3 and rear heat exchanger plates 4 are respectively arranged with left deep bead 8 and right deep bead, and left deep bead 8 and right deep bead are connected with base plate 5 with top board 6 respectively.
The present invention, angle between front heat exchanger plates 3 and rear heat exchanger plates 4 is reduced, horizontal range is suitably pulled open simultaneously, the volume of the cavity that V-type heat exchanger is formed increases, be conducive to the circulation of air, especially the air passage rates of V-type exchanger base becomes large, and the heat exchange efficiency of V-type exchanger base is improved; The setting of water conservancy diversion projection, will be conducive to the hot-air of V-type exchanger base by among fan fast pumping to environment, avoids hot-air to form the swirl flow dead band of localized hyperthermia in the bottom in V-type heat exchanger space.Make flowing more unobstructed; In addition, V-type heat exchanger structure will make heat exchanger bulk convection fan even, thus heat exchange is comparatively even.Avoid the localized heat stress caused because of the heat exchange uneven generation refrigerant exit temperature difference.Extend the working life of equipment; V-type heat exchanger structure makes the heat exchanger structure of bottom be fully utilized, and effectively improves the feature that traditional V-type exchanger base operating efficiency is low.V-type heat exchanger structure is when air-conditioning work load increases, and the mode by increasing fan flow makes the overall steadily rising of efficiency of heat exchanger, avoids the problem that top and bottom heat exchange efficiency gap increase further when large load operation.
Below know-why of the present invention is described in conjunction with specific embodiments.These describe just in order to explain principle of the present invention, and can not be interpreted as limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present invention, and these modes all will fall within protection scope of the present invention.
