Abstract
The utility model provides a water expansion tank of an automobile, which belongs to the technical field of automobiles. The water expansion tank solves the problems that wiring harnesses in a cabin is easily aged as water vapor can be generated on the existing water expansion tank. The water expansion tank of the automobile comprises a hollow tank body and a water inlet pipe with an upward opening, wherein the water inlet pipe is arranged on the tank body and communicated with a cavity body of the tank body; a radiator cover is connected with a port of the water inlet pipe; the wall of the tank body is provided with a vertically downward flow channel; an air vent communicated with the cavity body of the tank body is arranged on the radiator cover; and the lower end of the flow channel is communicated with the outside, and the upper end of the flow channel is communicated with the air vent. The water vapor of the water expansion tank of the automobile flows to the bottom under the water expansion tank through the flow channel and the air vent, thereby avoiding the aging of the wiring harnesses in the cabin due to the increase of the temperature and the humidity in the cabin.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of swelling water tank of automobile.
Background technique
Swelling water tank is the requisite Safety function element of car engine cooling system, this swelling water tank be accommodate with bucking-out system in the breathing amount of water, when motor car engine is worked, the cooling system temperature of automobile raises, cooling liquid will expand, if the cooling liquid steam enters in the swelling water tank, flow back to radiator after the cooling, can prevent a large amount of evaporation losses of cooling liquid, can also improve the boiling temperature of cooling liquid, at this moment swelling water tank has played elimination cooling system low-pressure section steam, makes it unlikely generation air-resistance phenomenon, give cooling water because temperature simultaneously, load, rotation speed change produces the leeway of expanding, and guarantees the cooling water circulation volume.At present swelling water tank has two kinds, and a kind of have pressure, and another kind is not have pressure; The swelling water tank that has pressure generally is provided with pressure cover on casing, on the sidewall of pressure cover, be provided with spill pipe, when swelling water tank expands, when temperature is spent above 100, can produce water vapour on the swelling water tank, water vapour can spray in the cabin by spill pipe, and temperature or humidity in the cabin are increased, and causes the wire harness in the cabin easily aging.
Summary of the invention
The purpose of this utility model is at existing deficiency, provides a kind of water that can make to steam the swelling water tank that water flows directly to the automobile of swelling water tank below.
The purpose of this utility model can realize by following technical proposal: a kind of swelling water tank of automobile, comprise a hollow casing and be opened on the casing and with the casing cavity is communicated with and opening makes progress intake pipe, port at intake pipe connects a radiator pressure cap, it is characterized in that, offer straight down a flow channels on the described box body wall, offer a vent that is communicated with the casing cavity on the described radiator pressure cap, the lower end of above-mentioned flow channels is in communication with the outside, and the upper end is communicated with vent.
The swelling water tank of this automobile mainly is made up of casing and intake pipe, this intake pipe and casing are integral structure, intake pipe is positioned at the upper end portion of casing, the opening of this intake pipe up, at the port of intake pipe clamping one radiator pressure cap, radiator pressure cap and intake pipe are tightly connected, when swelling water tank expands, when temperature is spent above 100, can produce water vapour on the swelling water tank, this water vapour flows to the lower bottom part of swelling water tank by the vent of radiator pressure cap and the flow channels on box body wall.
In the swelling water tank of above-mentioned automobile, described radiator pressure cap is socketed in the port of intake pipe.This radiator pressure cap and intake pipe interference fit.
In the swelling water tank of above-mentioned automobile, described flow channels is opened on the sidewall of casing.This flow channels is along the length direction setting of wall box, and wall box is connected.
In the swelling water tank of above-mentioned automobile, described vent one port is positioned at madial wall, and dock with the upper end-hole of flow channels the another port.The radius of vent is identical with the radius of flow channels, the upper end-hole joint sealing of vent another port and flow channels.
Compared with prior art, offer straight down a flow channels on the swelling water tank box body wall of this automobile, offer a vent that is communicated with the casing cavity on this radiator pressure cap, the lower end of flow channels is in communication with the outside, and the upper end is communicated with vent; When swelling water tank expands, when temperature is spent above 100, can produce water vapour on the swelling water tank, this water vapour flows to the lower bottom part of swelling water tank by flow channels and vent, thereby avoided the increase of the temperature and humidity in the cabin, the wire harness that influences in the cabin is aging.
Description of drawings
Fig. 1 is the swelling water tank sectional structure schematic representation of this automobile.
Among the figure, 1, casing; 1a, flow channels; 2, intake pipe; 3, radiator pressure cap; 3a, vent.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, the swelling water tank of this automobile mainly is made up of casing 1 and intake pipe 2, this casing 1 inside has a cavity, this intake pipe 2 is positioned at the upper end portion of casing 1 and is communicated with the cavity of casing 1, the opening of this intake pipe 2 up, during actual the manufacturing, casing 1 and intake pipe 2 are integrally manufactured, at the port of intake pipe 2 clamping one radiator pressure cap 3, radiator pressure cap 3 and intake pipe 2 interference fit also are tightly connected, on radiator pressure cap 3, offer a vent 3a who is communicated with casing 1 cavity, on the sidewall of casing 1, offer straight down a flow channels 1a, this flow channels 1a is along the length direction setting of casing 1 sidewall, and with the perforation of casing 1 sidewall, the lower end of flow channels 1a is in communication with the outside, the upper end is communicated with vent 3a, the radius of vent 3a is identical with the radius of flow channels 1a, and the port that the upper end-hole of flow channels 1a and vent 3a are communicated with connects, the joint sealing of the port of flow channels 1a and vent 3a port; When swelling water tank expands, temperature surpasses 100 when spending, and can produce water vapour on the swelling water tank, the lower bottom part that vent 3a and the flow channels 1a along casing 1 wall on of this water vapour by radiator pressure cap 3 flows to swelling water tank.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
