Abstract

The utility model relates to a directional radiator with double cavities, which comprises a plurality of radiation fins connected by an upper interface and a lower interface. Every radiation fin is composed of two cavities and a rid fin. The radiuses of the cross sections of the front and the rear cavities are unequal. When the radiation fins are vertically arrayed and are assembled into the radiator, a convergent type airflow channel is formed. The utility model can enhance compressive strength, accelerate airflow movement speed, enhance heat transfer efficiency, enhance heat radiation temperature difference and increases heat radiation capacity. The utility model has the advantages of unique structure, light weight, invalidation weight reduction and material saving.

Description

The two-chamber directional heat radiator

It is the heating radiator of media with water or steam that the utility model relates to a kind of, particularly a kind of two-chamber directional heat radiator.

Chinese patent (patent No. is 93117913.0) has proposed a kind of " cast-iron radiator ", its every fin all is a cavity volume, and every fin all is the stretched moulding that front and back equate, the radiator that is assembled into by several this structure fin arranged verticals, be unfavorable for air motion, heat exchanger effectiveness is low, influences radiating effect; And traditional cast-iron radiator casting consumption of raw material is many, the volume heaviness.

The purpose of this utility model is to provide a kind of moulding uniqueness, and is in light weight, can accelerate air motion speed, improves heat exchange efficiency, improves the two-chamber directional heat radiator of heat dissipation capacity.

The purpose of this utility model is achieved in that a kind of two-chamber directional heat radiator, comprises the some fin that connect by last interface and lower interface, it is characterized in that fin is made of two cavity volumes and fin, and preceding cavity volume does not wait with back cavity volume cross section radius.Constitute convergence type gas channel S between the two adjacent fin.The preceding cavity volume top of fin is the moulding of E-F line.

The utility model has improved " cast-iron radiator " structure, is two cavity volumes with every heat sink design, and every fin all is the garden top cone that front and back cavity volume cross section radius does not wait, after the several cooling fins arranged vertical is assembled into radiator, form convergence type gas channel, can improve compression strength, accelerate air motion speed, improve heat exchange efficiency, improve the heat radiation temperature difference, increase heat dissipation capacity, the utility model moulding uniqueness, in light weight, reduce inert weight, save material.

Description of drawings

Fig. 1 is the front view of the utility model structural representation;

Fig. 2 is the left view of the utility model structural representation;

Fig. 3 is an A-A cutaway view among Fig. 1.

The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment:

Consult Fig. 1, Fig. 2, shown in Figure 3, the two-chamber directional heat radiator mainly is to be made of some fin 6 that last interface 1 and lower interface 4 connect, its fin 6 is made of former and later two cavity volumes and fin 2, and preceding cavity volume 3 does not wait with back cavity volume 5 cross section radiuses, preceding cavity volume 3 cross section radiuses are big, back cavity volume 5 cross section radiuses are little, two cavity volume outer wall a link to each other with the b straight line, can form the dome cone, when two or several cones are coaxial is arranged in parallel, after promptly the several cooling fins arranged vertical is assembled into radiator, constitute convergence type gas channel S between the two adjacent fin 6, rear portion b1 is wide, and anterior a1 is narrow; Preceding cavity volume 3 tops of fin 6 are the moulding of E-F line.

The utility model can adopt material monolithic cast moldings such as cast iron, cast aluminium alloy or casting copper alloys.
