Antifreeze device of heat pipe of automobile water tank

Abstract

The invention discloses an antifreeze device of a heat pipe of an automobile water tank. The antifreeze device is composed of an engine waste heat recovery system, a heat pipe antifreeze system, an electric heating system and a temperature control system. The engine waste heat recovery system consists of a communication pipe b and a heat accumulator. The heat pipe antifreeze system includes a mainheat collection pipe, a heat pipe row and a communication pipe a; the heat pipe row includes a plurality of heat pipes distributed on an automobile water tank uniformly; and the communication pipe aenables all heat pipes to be communicated with the main heat collection pipe; and an evaporation section of the main heat collection pipe is communicated with the heat accumulator. The electric heating system includes an electric heating sleeve, an electric heating switch, and a temperature probe b; the electric heating sleeve coats the periphery of the evaporation section of the main heat collection pipe; and the temperature probe b is arranged inside the heat accumulator. And the temperature control system enables the temperature of the automobile water tank to be kept within a set temperature range. With the residual heat of the automobile engine, freezing of cooling water in the automobile water tank can be prevented, so that the energy consumption is reduced; and the safety is high and the cost is low.

Description

technical field [0001] The invention relates to the technical field of antifreezing of auto parts, in particular to a heat pipe antifreezing device for an automobile water tank. Background technique [0002] In the cold winter, especially in winter nights, the atmospheric temperature is as low as subzero, and even tens of degrees Celsius below zero in the north. In this case, if the car does not work for a long time, the water tank of the car is very easy to freeze. As a very important part of the car cooling system, the freezing of the water tank will cause the water tank to rupture, affect the car cooling system, increase engine friction, cause the car to fail to start normally, and cause accidents in severe cases. [0003] For the freezing problem of automobile water tanks, the method of adding antifreeze to the water tank is generally used now, but the freezing point of antifreeze is generally -20°C~-10°C, which is far from enough for the severe northern winter, and the ...

Problems solved by technology

As a very important part of the car cooling system, the freezing of the water tank will cause the water tank to rupture, affect the car cooling system, increase the friction of the engine, cause the car to fail to start normally, and cause accidents in severe cases

[0003] For the freezing problem of automobile water tanks, the method of adding antifreeze to the water tank is generally used now, but the freezing point of antifreeze is generally -20°C~-10°C, which is far from enough for the severe winter in the north, and the antifreeze ability is limited.

In addition, the antifreeze needs to be checked and replaced regularly

In addition, antifreeze contains phosphate, nitrate, etc., which are harmful to the environment.
