Technical field
The present invention relates to technical field of central air, particularly relate to the board-like V-type heat-exchanger rig of a kind of grid.
Background technology
Air conditioner refrigerating technology has indispensable effect in people's daily life and business application aspect.Along with the consumption of the energy and in short supply, energy-saving and emission-reduction become the importance in China's process of economic development.The room refrigeration being mainly used in summer in daily life of air conditioner refrigerating technology, Partial Food processing enterprise also needs freezer to carry out food fresh keeping.The energy that China's air-conditioning consumes is comparatively large, effectively can alleviate energy shortage, reach the object of energy-saving and emission-reduction by the refrigerating efficiency improving air-conditioning.The V-type heat exchanger of central air-conditioning is the vitals that air-conditioning and outdoor environment carry out heat exchange, and its heat exchange efficiency will directly have influence on the operational efficiency of air-conditioning entirety.As shown in Figure 1, current V-type heat exchanger angle is generally 50 ~ 60 degree, carries out withdrawing air heat convection by the fan at top.Find with emulated data by experiment, the convection velocity at the top of V-type heat exchanger is comparatively large, and the semiconvection wind speed of bottom is less, and heat exchange efficiency is very low, or even works hardly.In order to optimize the flow field of V-type heat exchanger, realizing the object that heat exchange efficiency improves, therefore needing to explore novel V-type heat exchanger structure.
Summary of the invention
The object of the present invention is to provide a kind of heat exchange efficiency high, the board-like V-type heat-exchanger rig of the uniform grid of heat exchange.
For reaching this object, the present invention by the following technical solutions:
Beneficial effect of the present invention: the present invention includes
The board-like V-type heat-exchanger rig of a kind of grid, comprise V-type heat exchange casing, be arranged on the air exhausting device at described V-type heat exchange casing top, and the Turbogrid plates be arranged in described V-type heat exchange casing, described Turbogrid plates are arranged at the below of described air exhausting device, and described Turbogrid plates and described V-type heat exchange casing top fastening.
Wherein, described Turbogrid plates comprise front Turbogrid plates and rear Turbogrid plates, are provided with angle between described front Turbogrid plates and described rear Turbogrid plates.
Wherein, the angle arranged between described front Turbogrid plates and described rear Turbogrid plates is set to acute angle.
Wherein, described front Turbogrid plates are disposed adjacent with the front heat exchanger plates being arranged on V-type heat exchange casing, and described rear Turbogrid plates are disposed adjacent with the rear heat exchanger plates being arranged on V-type heat exchange casing.
Wherein, described front Turbogrid plates are identical with described rear Turbogrid plates structure and length is equal.
Wherein, the length of described front Turbogrid plates and described rear Turbogrid plates is all less than the length of described front heat exchanger plates and described rear heat exchanger plates.
Wherein, described front Turbogrid plates and described rear Turbogrid plates run through respectively and are provided with airflow hole.
Beneficial effect of the present invention: the present invention includes V-type heat exchange casing, be arranged on the air exhausting device at described V-type heat exchange casing top, and the Turbogrid plates be arranged in described V-type heat exchange casing, described Turbogrid plates are arranged at the below of described air exhausting device, and described Turbogrid plates and described V-type heat exchange casing top fastening.By the setting of Turbogrid plates, can, in the flow blockage effect of Turbogrid plates, the convection velocity at heat-exchanger rig top suitably be reduced, and the convection velocity of bottom increase.And then the negative pressure formed under the effect of air exhausting device is uniformly distributed on V-type heat exchange casing, improve the operating efficiency of V-type heat exchange casing bottom, thus achieve the homogenising of Convective wind speed, and then the heat exchange efficiency everywhere realizing V-type heat exchange casing is comparatively even.

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.
As shown in Figures 2 to 4, the board-like V-type heat-exchanger rig of a kind of grid, comprise V-type heat exchange casing 1, be arranged on the air exhausting device 3 at described V-type heat exchange casing top, and the Turbogrid plates 2 be arranged in described V-type heat exchange casing, described Turbogrid plates are arranged at the below of described air exhausting device 3, and described Turbogrid plates and described V-type heat exchange casing top fastening.Preferably, air exhausting device 3 is set to fan.
Preferred further, described Turbogrid plates comprise front grid 21 plate and rear Turbogrid plates 22, are provided with angle between described front grid 21 plate and described rear Turbogrid plates 22, and the angle arranged between described front grid 21 plate and described rear Turbogrid plates 22 is set to acute angle.
Preferred further, described front grid 21 plate is disposed adjacent with the front heat exchanger plates 11 being arranged on V-type heat exchange casing 1, and described rear Turbogrid plates 22 are disposed adjacent with the rear heat exchanger plates 12 being arranged on V-type heat exchange casing 1.
Preferred further, described front grid 21 plate is identical with described rear Turbogrid plates 22 structure and length is equal.The length of described front grid 21 plate and described rear Turbogrid plates 22 is all less than the length of described front heat exchanger plates 11 and described rear heat exchanger plates 12, and described front grid 21 plate and described rear Turbogrid plates 22 run through respectively and are provided with airflow hole.
Adopt the V-type heat exchanger of said structure design to be made up of two panels heat exchanger plates, arrange in inverted triangle V-type, air is by entering inner chamber after forward and backward heat exchanger plates heat exchange, and the hot-air after heat exchange is discharged in environment by the fan at top again.The difference of V-type heat exchanger and traditional structure is: the angle between front heat exchanger plates 11 and 12 is comparatively large, and inner space is larger.Turbogrid plates are the thin plates with through-flow grid, are arranged on the suitable seat of V-type heat exchanger inside.In running, the air in environment enters into the inside of heat exchanger cavity by front heat exchanger plates 21 and rear heat exchanger plates 22.For traditional V-type heat exchanger, its top wind speed is large and bottom wind speed is little.For this kind of board-like V heat exchanger of novel grid, due to the flow blockage effect of Turbogrid plates, the convection velocity at heat exchanger top is suitably reduced, and the convection velocity of bottom increase.By the regulating action of Turbogrid plates, the negative pressure that fan is formed is uniformly distributed on heat exchanger, improves the operating efficiency of heat exchanger bottom, thus achieves the homogenising of Convective wind speed, and then the heat exchange efficiency everywhere realizing heat exchanger is comparatively even.By above form, the board-like V heat exchanger of novel grid can make heat exchange efficiency integrally be promoted.
