Description

FIELD OF THE INVENTION

The present invention relates to a radiator filter for automobile, and in particular to a filter that filter off impurities entraining coolant before the coolant is fed from an engine of the automobile to a radiator or that filters water of air heater water tank system before the water is fed to the air heater water tank system.

BACKGROUND OF THE INVENTION

In the operation of an automobile engine, due to the explosion of gasoline, a great amount of heat is generated, which leads to an increase of surrounding temperature. Most of the power systems that are known today use water as a coolant, which flows through a specially designed water channel system to passes every components of the engine for removal of heat therefrom. Depending on the arrangement used, the high temperature water will get to the apex of heat dissipation when it passes through a radiator. The radiator is made of a metal of low specific heat, such as copper and alloy, to form a water collection system, inside which tiny passages are formed to allow the liquid to contact the surrounding low-temperature air when passing through the passages to thereby dissipate heat. After passing the radiator, the temperature of the liquid becomes lower than engine temperature and is subsequently returned to the engine to absorb and thus bring away heat to the radiator. Such a process is repeated.

However after long time of use or when the coolant fed to the radiator contains impurities, such as carbon-contained impurity or in case that the radiator has not been cleaned for a long time, such impurities may get stuck among heat dissipation fins of the radiator, making the claps between the heat dissipation fins shortened thereby making it no longer possible for the heat dissipation fins to smoothly dissipate heat. Consequently, during the operation of the automobile, due to the heat of the radiator being not properly dissipated through the heat dissipation fins, the internal pressure of the radiator may get excessively high, leading to cracking of the radiator. The automobile may this get broken during the travel thereof and this may endanger the lives of the driver and the passengers.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a radiator filter for automobile, which is arranged between a water inlet of an automobile radiator and an engine to filter off impurities entraining coolant fed from the engine to the radiator so that no impurity may get stuck among heat dissipation fins of the radiator when the coolant flows through the radiator thereby preventing the radiator from breaking due to excessively high pressure inside the radiator caused by impurity accumulated among the heat dissipation fins of the radiator and thus preventing the automobile from getting broken during the travel thereof.

Another object of the present invention is to provide a radiator filter for automobile, which can be easily installed in and removed from a cooling system of an automobile and can be cleansed for repeated use.

A further object of the present invention is to provide a radiator filter for automobile, which can be used in an air heat water tank system for filtering water before the water is fed into the air heater water tank system to similarly remove impurity from the water to prevent the impurity entraining the water to cause any jamming making the air heater water tank system inoperable.

To achieve the above objects, the present invention provides a radiator filter for automobile, which comprises: a radiator, which comprises a plurality of heat dissipation fins mounted on a surface of the radiator, wherein the radiator comprises a radiator water inlet and a radiator water outlet; and a filter, which is connected to the radiator water inlet of the radiator so that cooling water fed from an engine of the automobile is guided through the filter to remove impurity contained in the cooling water and the impurity-removed cooling water is fed through the radiator water inlet into the radiator for effecting heat exchange and thus achieving the purposes of cooling.

In an embodiment of the present invention, the filter comprises a filter net that has a mesh having a maximum opening diameter of 0.5 mm.

In an embodiment of the present invention, the filter net is made stainless steel.

In an embodiment of the present invention, the filter net is made of plastics.

In an embodiment of the present invention, a pipe is further included for connecting the filter and the radiator water inlet of the radiator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention discloses a radiator filter for automobile, wherein a filter is arranged in front of coolant fed from an engine to a radiator in order to remove impurity from the coolant and prevent the impurity entraining the coolant from entering the radiator and accumulating among heat dissipation fins of the radiator, consequently making the radiator broken due to excessively high internal pressure. To help fully understanding the present invention, a detailed description is provided below to illustrate the process and the composition of the present invention. The manufacturing process and detailed steps of the manufacture of automobile radiators are not included in the description of the details of the present invention in order to eliminate unnecessary constraint on the scope of the present invention. However, details of preferred embodiments of the present invention will be clearly presented. It is understood that besides such details, the present invention is also applicable to other embodiments and the scope of the present invention is not limited thereto. The scope of the present invention is defined only by the appended claims.

Firstly, referring simultaneously to FIGS. 1 and 2. FIG. 1 is a schematic view showing a radiator the filter for automobile and FIG. 2 is an exploded view of the radiator the filter for automobile shown in FIG. 1. Referring directly to FIG. 2, the radiator filter 10 comprises at least a first cap 11, a first rubber sealing pad 12, a baffle 13, a filter net 14, a second rubber sealing pad 15, a transparent sleeve 16, and a second cap 17. The first cap 11 forms a filter water inlet 112 in an outside surface thereof and the second cap 17 forms a filter water outlet 172 in an outside surface thereof. The first rubber sealing pad 12 is positioned on an inner side of the first cap 11. The baffle 13 is arranged at the inner end of the filter water inlet 112 of the first cap 11. The baffle 13 comprises a block plate 132. The baffle 13 is fixed inside the first cap 11 by the block plate 132. Further, the filter net 14 has a hollow structure 142 and thus, the baffle 13 is received in the hollow structure 142 of the filter net 14. The filter net 14 has an inside diameter that is greater than an outside diameter of the block plate 132. When the baffle 13 is received in the hollow structure 142 of the filter net 14, the filter net 14 abuts and fixes the block plate 132 of the baffle 13 in position, The transparent sleeve 16 of the radiator filter 10 has an inside diameter that is greater than an outside diameter of the filter net 14 and thus the filter net 14 is receivable in the transparent sleeve 16. The transparent sleeve 16 is fit to an inner side (not shown) of the second cap 17 with the second rubber sealing pad 15 located between the second cap 17 and the transparent sleeve 16. Formed in an outside surface of the second cap 17 is a filter water outlet 172.

In an embodiment of the present invention, the filter net 14 has a mesh size having a maximum opening diameter of 0.5 mm. The opening diameter is corresponding to spacing distance between heat dissipation fins 22 of a radiator 20 (see FIG. 3) for the purposes of removing impurity of large size particles contained in cooling water with the filter net 14 and preventing the cooling water that contains too many impurities from entering the radiator 20 to cause the impurities accumulation among the heat dissipation fins 22 and thus leading to excessive pressure that might cause breaking of the radiator.

Further, in the present invention, the first rubber sealing pad 12 and the second rubber seating pad 16 are provided for purposes of sealing, leaking prevention, and cushioning. The filter net 14 is made of stainless steel or plastics.

Referring to FIG. 3, FIG. 3 is a cross-sectional view of the radiator filter for automobile. In FIG. 3, the radiator 20 comprises a plurality of heat dissipation fins 22, a radiator water inlet 24, and a radiator water outlet 26. The plurality of heat dissipation fins 22 is arranged on a surface of the radiator 20 to increase contact area of the radiator 20 with air and thus increase heat dissipation efficiency. The radiator water inlet 24 is arranged at a top of the radiator 20 to receive cooling water (which is usually hot water) into the radiator 20. The radiator water outlet 26 is arranged at a bottom of the radiator 20 to allow the cooling water flowing through the radiator 20 to be discharged through the radiator water outlet 26.

Thus, in the present invention, the filter 10 is connected by a pipe 30 to the radiator water inlet 24 of the radiator 20 and an opposite end of (not labeled) of the filter 10 is connected by another pipe 32 to an automobile engine (not shown). Specifically, the filter 10 is connected, with the filter water outlet 172 of the second cap 17 shown in FIG. 2, to the radiator water inlet 24 of the radiator 20 by the pipe 30 and the filter 10 is also connected, with the filter water inlet 112 of the first cap 11 shown in FIG. 2, to the automobile engine by another pipe 32, whereby the filter 10 is arranged between the automobile engine and the radiator 20, whereby before the cooling water is fed from the engine into the radiator 10, the filter net 14 of the filter 10 first filters off the impurities entraining the cooling water so that the cooling water fed into the radiator 20 contain no large size particle that might get stuck among the heat dissipation fins 22 of the radiator 20.

In an embodiment of the present invention, the spacing distance between adjacent heat dissipation fins 22 of the radiator 20 is around 0.5 mm to 1 mm and thus the mesh opening diameter of the filter net 14 of the filter 10 is selected to be of a maximum value of 0.5 mm. When the cooling water flows from the automobile engine through the filter 10, large size particles entraining the cooling water are intercepted by the filter net 14 and are not allowed further entraining the water flow into the radiator 20. This ensures that the cooling water flowing through the radiator 20 does not carry large size particles and no accumulation of impurity among the heat dissipation fins 22 will occur. Thus, the potential risk that the radiator 20 is broken by excessive pressure is alleviated. Further, the transparent sleeve 16 of the filter 10 disclosed in the present invention can be used for visual inspection of accumulation of impurity to determine if it is necessary to remove the filter for cleansing. The filter so cleansed can be used again. The installation and removal of the filter are easy, making it easily applicable to automobile cooling system and an air heater water tank system and the time and expense that are needed for cleansing the radiator and water tank can be reduced.

Although the present invention has been described with reference to the preferred embodiment thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
