Description

Vehicle tank filter

The invention discloses a vehicle water tank filter, in particular to a filter for filtering impurities in the cooling water before the vehicle engine injects the cooling water into the water tank.

When the engine of the vehicle is running, a large amount of heat is generated due to the explosion of the gasoline, causing the ambient temperature to rise. Most of today's powertrains use water as a cooling agent, which passes through a specially designed waterway system that flows through the engine components and removes heat. According to the design, all the hot water will reach the peak of the temperature when passing through the water tank. The water tank is a water collecting system formed of a low specific heat metal such as copper or aluminum. The inside of the water tank has a relatively fine pipe that allows the liquid to come into contact with the surrounding cold air when passing through, thereby dissipating the heat and flowing through the water tank. The water temperature will be lower than the engine temperature and continue to circulate into the engine to absorb heat, which is brought into the tank and dissipated.

However, under prolonged use, or when the cooling water injected into the water tank often contains impurities, such as carbon-containing impurities, or the water tank has not been cleaned for too long, it is easy for these impurities to accumulate between the cooling fins of the water tank, resulting in The spacing between the heat dissipating blades is reduced, so that the heat dissipating blades can not smoothly dissipate the heat. Therefore, during the running of the car, since the heat of the water tank cannot be dissipated by the heat dissipating blades, the pressure of the water tank is too large, causing the water tank to rupture. Therefore, it is easy to cause the car to break down during the driving process of the car, and may even cause life danger to the driver and the passenger.

The main object of the present invention is to disclose a vehicle water tank filter disposed between a water tank inlet of a vehicle water tank and an engine for filtering impurities in the cooling water injected into the water tank by the engine, so that the cooling water flows in the water tank. When there is no impurity accumulated in the cooling fins of the water tank, the water tank can be prevented from dissipating heat due to the heat dissipating blades, and the water tank is broken due to excessive pressure, and the vehicle can be prevented from being anchored during driving.

Another object of the present invention is to disclose a vehicle water tank filter that is easily detachable from a cooling system of a vehicle and that can be cleaned and reused.

According to the above object, the present invention discloses a vehicle water tank filter, comprising: a water tank, A plurality of heat dissipating blades are disposed on the surface of the water tank, wherein the water tank has a water tank inlet and a water tank outlet; and a filter is connected to the water tank inlet of the water tank to pass the cooling water injected by the vehicle engine through the filtering The device removes impurities in the cooling water, and then the filtered cooling water is injected into the water tank from the water tank inlet for heat exchange to achieve cooling.

In one embodiment of the invention, the filter has a cylindrical screen having a mesh aperture of at most 0.5 millimeters (mm).

In an embodiment of the invention, the material of the cylindrical filter is stainless steel.

In an embodiment of the invention, the material of the cylindrical filter is a plastic material.

In an embodiment of the invention, a pipe fitting is connected to the water inlet of the filter and the water tank of the water tank.
