Description
Technical field
The present invention relates to the cooling system of motor, particularly relate to a kind of engine-cooling system based on phase change fluid/water.
Background technique
At present, powerful engine-cooling system greatly mainly with water as cooling medium, water temperature is substantially at 70-90 DEG C, owing to not undergoing phase transition in course of conveying at this temperature range inner cooling water, the heat of conveying is sensible heat, heat memory density is low, so, under certain temperature difference cooling water per unit volume fluid the heat that can " carry " very limited.This is for high power engine and the very high occasion of other transfer heat demand, and required cooling water flow is very large, and this not only causes whole cooling system huge, and needs to consume a large amount of transfer pump merits.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of flow, the engine-cooling system based on phase change fluid/water that reduces pump consumption of saving cooling medium.
The present invention solves the problems of the technologies described above adopted technological scheme: a kind of engine-cooling system based on phase change fluid/water, comprise motor, water quench system and phase change fluid cooling system, described water quench system comprises the first pump, first modulating valve and heat exchanger, the first described pump is connected with described heat exchanger with the first described modulating valve respectively, the body of described motor is provided with cooling water inlet, cooling chamber is provided with between the body of described motor and cylinder sleeve, described cooling water inlet is connected with described cooling chamber, the cylinder cap of described motor is provided with coolant outlet, the first described modulating valve is connected with described cooling water inlet, described coolant outlet is connected with described heat exchanger, described phase change fluid cooling system comprises the second pump and the second modulating valve, described cooling chamber internal fixtion is provided with the spiral helicine cooling tube for passing into phase change fluid, the second described pump is connected with described heat exchanger with the second described modulating valve respectively, the second described modulating valve is connected with the import of described cooling tube, the outlet of described cooling tube is connected with described heat exchanger.
The second described modulating valve is ratio adjusting valve, the outlet port of described cooling tube is provided with temperature controller, ratio adjusting valve described in described temperature controller controls, when the temperature of the phase change fluid flowing out cooling tube outlet is still in phase change zone, temperature controller can control the aperture of ratio adjusting valve, turn the flow of phase change fluid in phase change fluid cooling system down, make the temperature of the phase change fluid of outflow cooling tube higher than the maximum temperature between phase change zone, thus maximally utilise the latent heat of phase change of phase change fluid.
The temperature range of described cooling chamber is 70 ~ 90 DEG C.
Described cooling tube is unsettled to be arranged in described cooling chamber or to be attached on the outer wall of described cylinder sleeve, when on the outer wall that cooling tube is attached to cylinder sleeve, better to the cooling effect of motor.
Described heat exchanger is shell-and-tube heat exchanger, is provided with two separate heat exchange pipelines and is respectively used to the cooling of cooling water and the cooling of phase change fluid in described shell-and-tube heat exchanger.
The phase change fluid used in described phase change fluid cooling system is phase change paraffin microemulsion, phase change paraffin microcapsule suspensions or other phase transition temperature interval be at the phase change fluid of 70 ~ 90 DEG C.
Liquid tank is provided with in described phase change fluid cooling system, between the outlet that described liquid tank is connected to described cooling tube by bleeder valve and described heat exchanger, when overhauling motor, the phase change fluid in recyclable phase change fluid cooling system.
Described a kind of engine-cooling system based on phase change fluid/water, be provided with expansion tank, be provided with demarcation strip in described expansion tank and expansion tank be divided into two inner chambers, inner chamber in described expansion tank is connected with the first described modulating valve, the second described modulating valve one_to_one corresponding respectively, after the cooling liquid (cooling water and phase change fluid) in cooling system adds thermal expansion, can be discharged in expansion tank.
Compared with prior art, advantage of the present invention is owing to being provided with phase change fluid cooling system, namely phase change fluid is passed within the engine as cooling medium, under the identical density of heat flow rate of motor, because the heat-carrying density of phase change fluid is large, greatly can save the circular flow of cooling medium, reduce pump consumption, there is energy-saving effect; Meanwhile, phase change fluid absorbs heat with latent heat of phase change form in motor, because the temperature range of phase-change material is narrower, makes the temperature of engine cylinder-body more equal; Again because water quench system and phase change fluid cooling system are two independent cooling subsystems controlled, its regulable control is flexible, and maintenance is convenient; In addition, owing to cooling tube being arranged in the cooling chamber between the body and cylinder sleeve of motor, during work, cooling tube is immersed in and passes in the cooling water of motor, make use of in-engine cooling water heating phase change fluid makes it undergo phase transition a large amount of latent heat of absorption, compared with carrying out cooling with net income phase change fluid, to avoid on wall that phase change fluid particle is attached to cylinder sleeve of engine and to affect the heat transfer of cylinder sleeve, thus prevent engine overheat and produce danger, also reduce the cooling cost of motor simultaneously.
