Description

HEAT EXCHANGER APPARATUS FOR RADIATOR

Technical Field

[1] The present invention relates to a heat exchanger for radiator, and more particularly to a heat exchanger for radiator which can increase the heat efficiency, while reducing the power consumption.

Background Art [2] A heat exchanger has been generally used including a radiator, a heater, a table dishes dryer, a clothing dryer, and the like.

[3] The afore-described radiator is addressed as one embodiment of the heat exchanger.

[4] The radiator R for heating the indoor room, as depicted in FIG. 1, comprises a plurality of radiant heat plate 2, and a body casing 4 installed in an upper and lower portion thereof to communicate with the radiant heat plate 2. [5] The radiant heat plate 2 and the body casing 4 are filled with fluids 4' such as oil or water, and a heat exchanger A" is installed inside the body casing 4. [6] In the afore-described radiator R, the heat exchanger A" is generally installed in the body casing 4 provided at the lower portion of the radiant heat plate 2, and the fluids 4' in the radiant heat plate 2 is heated by the heat exchanger's heating. [7] The heat exchanger A" is one in which a heating wire 32 is inserted into a coiled tube body 30 formed in approximately "U" shape, and subsequently the anode and the cathode of a power line 5 are connected at the end thereof. When the power is applied to the heat exchanger A" through the power line 5, the heating wire 32 is heated, such that the heat transfer can be conducted. [8] In such a case, there arose a problem in that although the heat capacity can be increased as the number of the afore-described coiled tube body 30 becomes increasing, the power consumption can be also increased in proportion thereto. [9] That is, the conventional heat exchanger having two coiled tube body is typically known to consume 2 kw, in which about 750 w is consumed in one-step mode, and about 1250 w is consumed in two-step mode.

[28] Referring to FIGS. 2 and 3, the present invention largely comprises an outer tube body 20, having a hollow being formed inside thereof, an opening part 24 at a rear end thereof, and a front end thereof being closed; a coiled tube body 30 in which a heating wire connected with the power is embedded, and being inserted into the outer tube body 20 in plurality; a magnesium powder part 10 filled in the front end inside the outer tube body 20; a plurality of magnesium fragments 80 inserted into the outer tube body 20; an insulating layer 60 adhered to the rear end of a final magnesium fragment of the opening part 24; and a cover 70 sealing the opening part 24.

[29] The outer tube body 20 is a large diameter tube body having a hollow inside thereof, wherein the front end is closed, and the rear end is opened by the opening part 24. In the outer periphery surface of the opening part 24, a screw part 22 is formed thereon to be able to be connected to the afore-described radiator R, and it is formed with a good conductive metal such as copper, aluminium, and stainless steel, with excellent heat transfer efficiency.

[30] The coiled tube body 30 is a small diameter tube body prepared by a metal such as copper and aluminium with good heat conductivity, and is bended in "U" shape, wherein the heating wire 32 which is a nichrome wire is inserted into inside thereof.

[31] In addition, connection terminals 40 connected thereto an anode and a cathode of the power line 5 are respectively formed at both ends of the coiled tube body 30.

[32] The afore-described coiled tube body 30 is preferably provided in even number, typically two to four being suitable, as a rule.

[33] That is, in one embodiment of the present invention, two coiled tube bodies 30 are illustrated as an example, but, as depicted in FIGS. 8 and 9, four coiled tube bodies 30 are possible as another embodiment to be able to practice the present invention. Thus, when four coiled tube bodies 30 are used, eight connection terminals 40 are formed, and a common terminal 50 connected inbetween the anode terminals are formed.

[42] The magnesium, Mg, has a property of increasing the heat efficiency, and thus it is expressively effective in reducing the power consumption.

[43] As previously described, the insulating layer 60 is formed by inserting the coiled tube body 30 into the outer tube body 20 to form the magnesium powder part 10, inserting and combining the magnesium fragments 80 therewith, putting a filler such as urethane being able to withstand high temperature at the rear end of the final magnesium fragment 80, and injecting an adhesive (see FIG. 3).

[44] The cover 70 is installed at outer side of the insulating layer 60 to seal the opening part 24, preferably made of clay or ceramic material, in which a plurality of through- holes (not illustrated) are formed such that the connection terminals 40 can be passed therethrough.

[45] The combination and working of the thus configured present invention will be described referring to FIG. 5.

[46] First, the heating wire 32 is inserted into the coiled tube body 30, and subsequently the connection terminals 40 are formed at both ends thereof. [47] Then, the coiled tube body 30 is selected in suitable number, and subsequently insertig the same into the outer tube body 20.

[48] Then, the magnesium powder is filled through the opening part 24 of the outer tube body 20 to form the magnesium powder part 10 at the front end inside thereof, and subsequently the magnesium fragments 80 are inserted thereinto in order, to fill the inner part of the outer tube body 20.

[49] Then, the afore-described insulating layer 60 is formed outside of the final magnesium fragments, and subsequently connecting the cover 70 and sealing the opening part 24 to complete the combination of the present invention A.

[50] The thus combination-completed heat exchanger A is inserted into and screw- connected with the body casing 4 of the radiator R, and subsequently the power line 5 is connected to the connection terminals 50 of the each coiled tube body 30, and the common terminal 50 is connected inbetween the anode connection terminals.

[51] Then, the switch, not illustrated, is operated to select the operating mode, and thereby allowing the invention to operate in one or two-step operating mode.

[52] On the other hand, FIG. 6 is a perspective view for other embodiment of a heat exchanger for radiator in accordance with the present invention, and FIG. 7 is a sectional view of FIG. 6.

[53] Referring to those figures, the present invention further comprises a plurality of heat radiant fins 25 outside the outer tube body 20, such that it can generate a hot wind by operating a blower (not illustrated) provided at one side of the radiator R, wherein the inner structure of the invention is the same with the afore-described first embodiment, as depicted in FIG. 7, and therefore repeated description on it is omitted.

[54] On the other hand, FIG. 10 is a perspective view for still another embodiment of a heat exchanger for radiator in accordance with the present invention. Referring this figure, the present invention further comprises a plurality of porous metal body 25' outside the outer tube body 20, such that it can generate a hot wind by operating a blower (not illustrated) provided at one side of the radiator R, while being able to obtain the air-conditioning effect, wherein the inner structure of the invention is the same with the afore-described first embodiment, as depicted in FIG. 7, and therefore repeated description on it is omitted.
