CN2205953Y - Plate-like air heater with reinforcing radiating tank - Google Patents

Abstract

The utility model discloses a tabular heater with reinforced heat radiating tanks, which is formed by that a plurality of upright tanks with small upper openings and big lower openings are arranged at the front and the back faces of the ordinary tabular heater to form a chimney-shaped heat radiating structure. Air heated on plate faces rises in a chimney; the speed is continuously increased, and thus the hot and cold exchange of the indoor air is accelerated; forced convection occurs in the chimney, and thus the heat exchange coefficient of the air in the chimney is increased to increase the heat radiating capacity, increasing the heat radiating speed and effect of the original tabular heater.

Description

Plate-like air heater with reinforcing radiating tank

The utility model relates to a kind of indoor heater, in particular, relates to the radiator structure of tabular indoor heater.

Tabular warmer is to use comparatively general new product structure in electric heater and the hot-water stove in recent years.For example Chinese patent CN2056221U proposes a kind of light-duty tabular heat pipe electric heater at the problem that the oil-filled heat pipe electric heater of column exists, its some little convex-concave arc road, cooling plate structure surface, the main natural convection air that relies on is dispelled the heat, indoor air temperature rises slower, need to strengthen heat-transfer effect and need strengthen the heat sink area or increase electrical power raising plate surface temperature, this problem of bringing is that power consumption is big and heat sink is huge.Be widely used in the tabular radiator of steel flat-tube radiator, steel of the depressed structure of northern China building hot-water heating for another example, though lean on the back side of wall can add some straight troughs heat radiations to flow at these tabular hot-water stoves, but straight trough is unhappy to gas flow in the flow, still belong to the natural convection air heat radiation, the radiator structure of these hot-water stoves requires further improvement.

The purpose of this utility model just provides a kind of tabular warmer that can produce forced air convection heat transfer' heat-transfer by convection effect, increases warmer intensification ability and heat convection speed, improves heat transfer efficiency.

Realize that the purpose of this utility model is by the front and back at existing tabular warmer, a plurality of big vertical slots formation chimney shape heat radiation air flues of young end opening of are installed are obtained.

The utility model has been compared following advantage with original tabular warmer: 1. room air heats up rapidly, because the air weight of being heated at the plate face lightens, can rise along chimney, simultaneously sectional area shrinks the chimney that diminishes gradually the flow velocity of hot-air will obviously be accelerated, and the indoor Rapid Thermal air that occurs flows the cold and hot exchange of air will be accelerated.2. indoor air temperature obviously raises, and this is that heat dissipation capacity increases than pure free convection heat exchange situation under the prerequisite that does not increase the heat sink area owing to forced-convection heat transfer occurred in the chimney.3. chimney shape vertical slot gas outlet, warmer upper end has than the heat-flash air-flow, can be in order to drying clothes, transpiring moisture to increase humidity etc.

Below in conjunction with drawings and Examples the present invention is elaborated.

Fig. 1 is the tabular electric heater structure diagram of one embodiment of the invention.

Fig. 2 is the profile that the A-A line along Fig. 1 obtains.

The tabular electric heater of band chimney shape radiating groove as shown in Figure 1, its structure is directly to clamp three electrothermal tubes that equidistantly sequence 2 between two heat-dissipating aluminium plates 1, near every electrothermal tube 2, two heat-dissipating aluminium plates are got up to form the tabular electric heater with rivet, before again the aluminum vertical slot 3 in 5 pairs of camber cross sections, recessed garden that upward young end opening is big being welded on the tabular electric heater respectively in twos accordingly, back two sides, form 5 pairs of chimneys, require them to cover respectively on three electrothermal tubes position central at interval, imitate high novel plate shaped electric heater thereby obtain a kind of rapid heat dissipation heat with being arranged in electrothermal tube.Present embodiment is through performance test: 14m ²In the building room, under no sunlight incident and the no hot-water heating situation, when switching on half water after aforementioned 600W tabular electric heater make room temperature rise to 16.5 ℃ by 15 ℃, rise to about 18 ℃ after one hour; And the novel plate shaped electric heater that is added with enhance heat chimney shape vertical slot of the present utility model, energising room temperature half an hour rises to 18 ℃ by 15 ℃, rises to 20 ℃ after one hour, and noticeable heat-flash air-flow appears in the place, gas outlet on chimney shape vertical slot simultaneously.

Claims (1)

1, a kind of indoor tabular warmer, main by heat sink, be installed in the heat source configurations in the heat sink, the radiator structure that is fixed on the heat sink is formed, it is characterized in that above-mentioned radiator structure is a kind of both ends open, go up the big vertical groove of young end opening, the lateral edges of groove closely is fixed on the heat sink and the chimney shape air flue that forms.
