Abstract

The utility model provides a composite column radiator, which mainly comprises an upper copper horizontal pipe and a lower copper horizontal pipe, the section of which is D-shaped, composite column radiating fins that are vertically connected with the upper copper horizontal pipe and the lower copper horizontal pipe, and ventilation hoods that are arranged in the upper and lower ends of the radiating fins. The central cavities of the column radiating fins are plated with copper pipes to be media passing cavities and communicated with the upper and lower copper horizontal pipes by welding, an outer side of the central chamber is provided with fins as a whole, at least more than two closed convective radiating cavities are formed between fins, and the outer surfaces of the radiating fins can be processed to be trapezoidal, cymbal-like, corrugated or triangular. The radiator has relatively good anticorrosion performance and can prevent leakage, the closed convective radiating cavities formed between fins can allow cool air to enter from the ventilation hood in the lower end and allow hot air to exit from the ventilation hood in the upper end, thus enhancing the radiating efficiency, and the utility model has dual functions of radiating heat transfer and convective heat transfer.

Description

The combined type columnar radiators

Technical field

The utility model belongs to heating equipment, particularly relates to a kind of combined type columnar radiators corrosion-resistant and that heat transfer efficiency is high that has.

Background technology

In present known aluminium section bar column radiator, all adopt radiant type heat radiation form, because the aluminium radiating effect is poor, cause its heat transfer efficiency low, the aluminium antiseptic property is not good enough simultaneously, easily causes the radiator seepage, brings inconvenience to the user.

Summary of the invention

The utility model provides a kind of have anticorrosion and the high combined type columnar radiators of heat transfer efficiency for solving the technical problem that exists in the known technology.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

The combined type columnar radiators comprises upper and lower transverse tube, is vertically connected at the heat sink compound of upper and lower transverse tube, be arranged at the pipe plug of lower transverse tubule one end, aluminium heat sink is cylindricality, studding with copper pipe in its lumen is that medium passes through the chamber, and be communicated with upper and lower transverse tube, ventilator cowling is plugged in cylindricality fin upper/lower terminal, and the cylindricality fin lumen outside is provided with the fin that is connected as a single entity with it, constitutes the heat radiation chamber between fin and fin.

The utility model can also adopt following technical measures:

Constitute between described fin and fin and be sealing convection type heat radiation chamber at least more than two.

Described cylindricality fin outer surface cross section can be trapezoidal, can also be cymbals shape, corrugated and triangle.

Described upper and lower transverse tube cross section is D shape.

Advantage and the good effect that the utlity model has are: owing to stud with copper pipe at cylindricality fin lumen, can improve the antiseptic property of radiator, avoid radiator seepage to occur; Constitute a plurality of heat radiations by fin cold air is entered from the lower end ventilator cowling, hot-air spreads out of by the upper end ventilator cowling, forms convection current with room air, can improve the radiating efficiency of radiator thus, makes it have radiant heat transfer and heat loss through convection is difunctional.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1 and Fig. 2, the combined type columnar radiators comprise its cross section be D shape on, following copper transverse tube 1, on being vertically connected at, the compound fin 3 of lower transverse tubule and be arranged at the pipe plug 4 of lower transverse tubule one end, the upper lateral tube two ends and the lower transverse tubule other end are intake-outlet 5, aluminium heat sink 3 is cylindricality, stud with copper pipe 6 in its lumen and pass through the chamber for medium, and with last, the lower transverse tubule welding is communicated with, ventilator cowling 2 is plugged on the cylindricality fin, following two ends, the cylindricality fin lumen outside be provided be connected as a single entity with it be radiation fin 7, constitute heat radiation chamber 8 between fin and fin, as shown in Figure 3, constitute three sealing convection type heat radiation chambeies 8 between the fin, fin outer surface cross section is trapezoidal, and as shown in Figure 4, its outer surface cross section can also be cymbals shape.

As shown in Figure 5 and Figure 6, constitute five sealing convection type heat radiation chambeies 8 between the fin fin, its outer surface cross section is trapezoidal, can also be cymbals shape.

As shown in Figure 7 and Figure 8, constitute three sealing convection type heat radiation chambeies 8 between the fin fin, its outer surface cross section is corrugated, can also be triangular in shape.
