Abstract
The utility model discloses an improved preheating device for cold starting of a motor, which comprises a water pump with a water absorption opening and a water outlet, wherein the water pump is provided with an enclosed heating container on the side surface with the water absorption opening; the other side of the heating container is provided with a water inlet; the water absorption opening of the water pump is arranged in the heating container, the internal part of which is provided with an electric heater; the electric heater is an insulated radiating pipe which is provided with a resistance wire; both ends of the insulated radiating pipe are sealed and arranged on the end surface of the heating container, and two end heads of the resistance wire are connected with an electric connecting seat on the external end surface of the heating container. A water outlet of the water pump of the utility model is connected with a water discharge outlet of the motor, and the water inlet of the heating container is connected with the water outlet of a thermostat of the motor. In cold seasons, when the motor of a motor vehicle is conducted with the cold starting, hot water heated by the electric heater is conveyed to the internal part of the water sleeve of the motor by the water pump. When hot water which is circularly heated causes the motor to be preheated to the normal temperature, the motor can be smoothly started.
Description
Technical field
The utility model belongs to motor car engine cold start-up Preheating unit, particularly improved engine cold-start Preheating unit.
Background technique
At present, all kinds of automobiles, tractor, Agricultural automotive vehicle start relatively difficulty under the lower environment of temperature, and particularly in the winter of the northern area of China, because temperature is very low, motor car engine is difficult to start in the season of severe cold.Usually the way that solves is to add antifreeze liquid in the water of water tank, freezes to prevent the water case, is difficult to the problem that starts at low temperatures but still can not solve motor.Have only Motor Vehicle is parked in the garage with heating equipment, motor car engine is not subjected to the influence of outdoor low temperature, and the engine start ratio is easier to.But a lot of Motor Vehicle do not have garage or garage not to have heating equipment, still can't solve the problem of engine start difficulty at low temperatures.
Summary of the invention
The purpose of this utility model is to provide a kind of improved engine cold-start Preheating unit, can in advance in-engine cooling water be heated to normal temperature, and motor can normally be started.
The purpose of this utility model is achieved in that a kind of improved engine cold-start Preheating unit, comprise the water pump that has water sucking mouth and water outlet, has the heating container that sealing is installed on the side of water sucking mouth at water pump, the opposite side of heating container is being provided with water intake, the water sucking mouth of water pump is positioned at heating container, electric heater is installed in heating container, electric heater is the insulating radiation pipe that resistance wire is housed, insulating radiation pipe sealed at both ends is installed on the end face of heating container, and two terminations of resistance wire are connected with the electric connection socket on the heating container exterior edge face.
The utility model is installed on the base of motor sidepiece, and the water outlet of water pump is connecting the dewatering outlet of motor by pipeline, and the water intake of heating container is connecting the water outlet of motor thermostat by pipeline.In the season of cold weather, when motor car engine needs cold start-up, electric heater is switched on, the resistance wire heating of electric heater heats up the water in the heating container, water pump rotates heated water in the heating container is transported in the cooling jacket of motor, make water in the engine cooling water jacket heat temperature raising that constantly circulates, when making engine warming up, motor successfully can be started to normal temperature.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a broken section structural representation of the present utility model.
Embodiment
A kind of improved engine cold-start Preheating unit, as shown in drawings, comprise the water pump 2 that has water sucking mouth 4 and water outlet 1, has the heating container 3 that sealing is installed on the side of water sucking mouth 4 at water pump, heating container 3 has the tank body of adpting flange for opening, by sealing gasket 9 and adpting flange heating container 3 sealings is installed on the side of pump sump mouth 4 one sides.The opposite side of heating container 3 is being provided with water intake 7, the water sucking mouth 4 of water pump 2 is positioned at heating container 3, on the mouth of pipe of pump sump mouth 4, filter screen is installed, in heating container 3, electric heater is installed, electric heater is the insulating radiation pipe 5 that resistance wire 6 is housed, insulating radiation pipe 5 sealed at both ends is installed on the end face of heating container 3, and two terminations of resistance wire 6 are connected with the electric connection socket on heating container 3 exterior edge faces.Insulating radiation pipe 5 be shaped as spiral element or U-shaped pipe.Thermal insulation layer 8 is being set on the housing of heating container 3,, is improving the efficiency of heating surface to reduce scattering and disappearing of heating heat.
