It applies in example, the underface for being set to air outlet 13 of several 41 parallel intervals of radiant panel, by the center of through-hole 171 on wind deflector 17
Line (namely opening direction of through-hole 171) and the angle of air-out direction are set as 30 °~80 °, and being conducive to will be by through-hole 171
Wind is oriented to radiant panel component 40, and wind is made to be blown down along the air duct 42 that two neighboring radiant panel 41 is formed, is conducive to wind in radiant panel
41 surfaces carry out the quantity of heat convection.It should be understood that as shown in figure 4, in the present embodiment, 17 closing air outlet 13 of wind deflector
When, the center line and the angle of vertical direction that define through-hole 171 are α 2,2≤6 ° of -6 °≤α, it is preferred that angle α 2 is -6 °, -
5 °, -4 °, -3 °, -2 °, -1 °, 0 °, 1 °, 2 °, 3 °, 4 °, 5 ° or 6 °.The angle of the center line of through-hole 171 and vertical direction is set
- 6 °~6 ° are set to, is conducive to, by by the wind of through-hole 171, when being oriented to radiant panel component 40, make wind along two neighboring radiant panel
41 air ducts 42 formed also generate a power forward or backward while blow down, be conducive to will by 41 surface of radiant panel into
The wind of row the quantity of heat convection is sent to room everywhere.As the preferred embodiment of the present embodiment, the thickness range of wind deflector 17
For 1~5mm, it is preferred that the thickness of wind deflector 17 is 2.5mm.
It should be understood that the arrangement form of through-hole 171 can be arbitrary.As the preferred embodiment of the present embodiment,
As shown in Figures 1 to 4, in the present embodiment, each 171 and one air duct 42 of through-hole is correspondingly arranged or each through-hole 171
With each 41 stagger setting of radiant panel.Air-flow is not directly blown onto after the blowout of through-hole 171 on the thickness direction of radiant panel 41, and
It is that the air duct 42 formed along radiant panel 41 is flowed, air-flow is made all to act on the surface of 41 both sides of radiant panel, it is possible to reduce gas
The loss of stream energy, reducing blocking makes air-flow blow farther along air duct 42, increases heat convection.
