Abstract

The utility model relates to a heating radiator, particularly a cast-iron radiation convection radiator in a post type. The utility model mainly solves the disadvantages that when the prior art is used for heat radiation, the hot airflow layer is thick, the heat transferring coefficient is low, the heat radiating effect is bad, and the volume is hard to be reduced. The utility model is composed of radiator fins which comprise water containing posts, wherein, the neighboring outer walls of one water containing post and the water containing post of the other radiator fin are provided with flat surfaces or cambered surfaces. The utility model is characterized in that needle-shaped fins are arranged on the flat surfaces or the cambered surfaces, and both outer sides of each fins are provided with post fins which are used for guiding airflow; the post fins are butted with post fins on a neighboring water containing post for forming an air passage for conducting the airflow.

Description

Column type radiation and convection radiator

The utility model relates to a kind of heating radiator, particularly column type cost iron radiation and convection radiator.

Existing column type cost iron heat radiator mostly is circle or oblong cavity column, heat radiation is mainly post surface and natural convection air heat exchange, and part is the radiation heat transfer of lateral surface, and its shortcoming is: convection velocity is slow during heat radiation, the thermal current bed thickness on post surface makes that heat transfer coefficient is low, radiating effect is poor.CN 87213771 once disclosed a kind of " radiation and convection radiator ", the characteristics of this radiator are to be furnished with vertical section rib on the outer wall of its appearance water column, convection velocity when dispelling the heat to increase area of dissipation and raising, but its shortcoming is: during heat radiation, the hot gas fluid layer that forms from bottom to top on the rib surface is more and more thicker, heat transfer coefficient is more and more lower, makes radiating effect relatively poor; In addition, have certain heat dissipation capacity for keeping radiator, just have to strengthen area of dissipation, this makes the volume of this radiator be difficult for dwindling, and is installed in to seem comparatively heavy in the dwelling house.

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and the thermal current layer thickness is thin when a kind of heat radiation is provided, heat transfer coefficient is high, heat transfer efficiency good, and under the situation that guarantees certain heat dissipation capacity, the column type radiation and convection radiator that volume can be less.

For finishing above-mentioned purpose, technical solution provided by the utility model is: a kind of column type radiation and convection radiator, by comprising that the radiator fin 1 that holds water column 2 constitutes, described appearance water column 2 is plane or cambered surface with the adjacent outer wall that another radiator fin holds water column, its special character is, on the plane of described adjacent outer wall or cambered surface, be arranged with needle-like fin 3, and be provided with the

post fin

4,5 of the air-flow that is used to lead in its two outside, this post fin 4,5 docks with post fin on the adjacent appearance water column, is configured for the air duct 6 of conducting air-flow.

Holding water column 2 described in the above-mentioned technical solution is best with the plane with the adjacent outer wall that another radiator fin holds water column, so relatively is convenient to make, and production cost is lower.

Appearance water column 2 in the above-mentioned technical solution can be single water column that holds, and also can be the double volume water column, is the best but hold water column with list, can make radiator have littler volume like this.

Needle-like fin 3 in the above-mentioned technical solution can be cylindrical needle-like fin, also can be oblate cylindricality, elliptical cylinder-shape, water droplet cylindricality, polygon cylindricality, or the needle-like fin of other shape, but its shape is produced to good to be suitable for to make.That these needle-like fins 3 can be on plane that holds the adjacent outer wall of water column or cambered surface is arranged in a straight line up and down, the regular arrangement of cross arrangement or other form up and down.

The accompanying drawing drawing is described as follows:

Fig. 1 is the radiator fin structural representation of a preferred embodiment of the utility model;

Fig. 2 is with two structural representations that radiator fin is combined shown in Figure 1;

Fig. 3 is the section structure schematic diagram of oblate cylindricality needle-like fin;

Fig. 4 is the section structure schematic diagram of elliptical cylinder-shape needle-like fin;

Fig. 5 is the section structure schematic diagram of water droplet cylindricality needle-like fin;

Fig. 6 is the section structure schematic diagram of polygon cylindricality needle-like fin.

Referring to Fig. 1, Fig. 2, this column type radiation and convection radiator is made up of a plurality of radiator fins 1 that hold water column 2 that comprise, described appearance water column 2 is single water column that holds, each holds water column 2 is the plane with the adjacent outer wall that another radiator fin holds water column, this plane is provided with and is cylindrical needle-like fin 3 arranged in a straight line up and down, be provided with two vertical posts fins 4,5 of the air-flow that is used to lead in its two outside, these two post fins 4,5 dock with post fin on the adjacent appearance water column, are configured for the rectangle air duct 6 of conducting air-flow.

Referring to Fig. 3, Fig. 4, Fig. 5, Fig. 6, the needle-like fin 3 among this embodiment can also be oblate cylindricality, elliptical cylinder-shape, water droplet cylindricality and polygon cylindricality.

In conjunction with the foregoing description as can be seen, the utility model has following advantage compared to existing technology:

1, because needle-like fin 3 profiles in the utility model are tiny, when heat radiation, its surperficial hot gas fluid layer does not thicken as yet, and radiating surface just disappears, makes and remains very thin hot gas fluid layer, heat transfer coefficient height, good heat dissipation effect on needle-like fin 3 surfaces; In addition, the air duct 6 that is used for the conducting air-flow surrounds needle-like fin 3 wherein, can accelerate airflow in the passage as a little chimney when heat radiation, and this will further accelerate the heat radiation of needle-like fin 3, improve its radiating efficiency; And the lateral surface that post

fin

4,5 exposes can also increase the heat loss through radiation amount of radiator.

2, because the hot gas fluid layer of the utility model when heat radiation is thin, the radiating efficiency height so can dwindle the volume of radiator guaranteeing that radiator has under the situation of higher heat dissipation capacity, takes up space radiator when mounted less, satisfies people to beautifying the requirement of dwelling house.
