The utility model relates to a fan heater technical field, concretely relates to fan heater thermal radiation protection and air current guiding device.

Background

When fuel in the combustion heat exchanger burns, the temperature in the combustion heat exchanger combustion chamber is very high, and combustion chamber internal face temperature is very high, and the combustion chamber internal wall produces great radiant heat, except the combustion chamber terminal surface, the radiant heat of other faces of combustion chamber can't directly radiate to the body shell, and the radiant heat of combustion chamber terminal surface directly acts on the electric fan heater terminal panel, causes the terminal panel temperature very high, causes calorific loss and people and middle-aged person to scald. In view of the above drawbacks, there is a need for a device for preventing heat radiation and guiding airflow of a fan heater.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a fan heater solar heat protection radiation and air current guiding device have reduced the temperature of fan heater terminal surface board, and have improved the heat transfer effect.

In order to achieve the above object, the utility model provides a following technical scheme: the warm air blower heat radiation prevention and airflow guide device comprises a case, a circulating fan, an end plate and a combustion heat exchanger, wherein the inner wall of the end plate is provided with a heat radiation prevention plate through a fixing piece, the heat radiation prevention plate is not attached to the end plate through the fixing piece, the upper end of the heat radiation prevention plate is provided with a guide plate, and the guide plate faces towards the air outlet of the circulating fan.

Through setting up the thermal radiation protection board, greatly reduced the temperature of electric fan heater end panel, the heat is absorbed by the thermal radiation protection board, and does not contact with the end panel, through the guide plate, has promoted the amount of wind, has reduced the windage.

Preferably, the middle part and the upper part of the heat radiation prevention plate are fixed on the inner wall of the end plate through fixing pieces and are parallel to the inner wall of the end plate, the fixing effect is good, and heat insulation is uniform.

Preferably, the mounting includes the multiunit registration arm, the registration arm is fixed at the end panel inner wall, the thermal radiation protection board passes through the bolt fastening at the registration arm end, and is fixed stable.

Preferably, the positioning pipe is perpendicular to the end plate, and the bolt is conveniently positioned.

Preferably, the thermal radiation protection plate lower extreme is buckled, is the arc form towards combustion heat exchanger direction, and thermal radiation protection plate lower extreme arc sets up, and with the guide plate cooperation, effectively reduces the windage, improves the amount of wind, promotes the heat transfer effect.

Compared with the prior art, the utility model discloses increase registration arm and heat-proof radiation board on the end panel, can prevent that the heat of combustion chamber high temperature terminal surface from directly radiating to the end panel on, not conducting the heat to the end panel as far as.

The arc-shaped lower end of the heat-proof radiation plate is matched with the guide plate, so that the wind resistance is effectively reduced, the wind quantity is increased, and the heat exchange effect is improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the warm air blower heat radiation preventing and airflow guiding device includes casing 1, circulating fan 2, chimney heat exchanger 3, end plate 5 and burning heat exchanger 8. The combustion heat exchanger 8 generates hot gas through work, hot flue gas enters the chimney heat exchanger 3, circulating air is formed in the case 1 through the circulating fan 2, and the hot flue gas is discharged from the chimney heat exchanger 3.

Burning heat exchanger 8 can produce the high fever at the during operation, and 5 inner walls of end panel are fixed through multiunit registration arm 6 and are equipped with solar panel 7, adopt thermal insulation material, and the heat insulating panel promptly, solar panel 7 do not laminate with end panel 5 through registration arm 6, and solar panel 7 passes through bolt 9 to be fixed at 6 ends of registration arm, and registration arm 6 is perpendicular setting with end panel 5.

The middle part and the upper part of the heat radiation prevention plate 7 are fixed on the inner wall of the end plate 5 through the positioning pipe 6 and are parallel to the inner wall of the end plate 5.

The upper end of the heat radiation prevention plate 7 is provided with a guide plate 4, the guide plate 4 is arc-shaped, the guide plate 4 faces the air outlet of the circulating fan 2, and the guide plate 4 is fixed at the top end inside the case 1 and is arranged on one side of the chimney heat exchanger 3.
