The diesel engine water tank heat radiation device has the advantages that the structure is reasonable, the cooling water loss is little, and the heat radiation efficiency is high.
Description
Technical field
The utility model relates to a kind of water tank heat dissipating device for engine.
Background technology
The water tank heat dissipating device of engine in the course of the work, cooling water enters upper tank by water inlet, and is descending by the fin on the radiator, cooling water is through after the heat radiation of fin, continue descending process lower header, taken away by water pump by delivery port afterwards, and continue this cyclic process always.
After original heat abstractor cooling fluid enters upper tank from water inlet, directly impact on the sidewall of upper tank, have the part spray to overflow by the passage of upper tank top, caused non-evaporation loss.
In addition, after cooling water impacts the sidewall of upper tank, most of cooling water is all descending along this place's sidewall, and water distribution is inhomogeneous, fails to be covered with whole upper tank, in above-mentioned cyclic process, cooling water is most of only to dispel the heat through fin along the sidewall of a side is descending, enters afterwards lower header and is taken away by water pump, and only some fin is in effective duty all the time, some fin then is not fully utilized in addition, and this has reduced radiating efficiency to a great extent.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of rational in infrastructure, cooling water loss is few, radiating efficiency is high heat radiation device of diesel.
For solving the problems of the technologies described above, the technical solution of the utility model is: heat radiation device of diesel comprises upper tank and lower header, be communicated with radiator between described upper tank and the described lower header, described upper tank is provided with water inlet, described lower header is provided with delivery port, and described upper tank top is provided with water injection pipe, and described water injection pipe is provided with filler cover, the sidepiece of described water injection pipe is provided with passage, is positioned at described water inlet in the described upper tank and is provided with the water distribution baffle plate.
As preferred technical scheme, described water distribution baffle plate is rectangular flat plate.
As to improvement of the technical scheme, described water distribution baffle plate is obliquely installed.
As preferred technical scheme, described water inlet is located on the described upper tank sidewall, the top edge of described water distribution baffle plate is connected with the upper tank inwall that is positioned at place, described water inlet top, and the lower limb of described water distribution baffle plate connects with the bottom of the upper tank inwall that is positioned at the relative side of described water inlet.
Owing to adopted technique scheme, heat radiation device of diesel, comprise upper tank and lower header, be communicated with radiator between described upper tank and the described lower header, described upper tank is provided with water inlet, and described lower header is provided with delivery port, described upper tank top is provided with water injection pipe, described water injection pipe is provided with filler cover, and the sidepiece of described water injection pipe is provided with passage, is positioned at described water inlet in the described upper tank and is provided with the water distribution baffle plate.Heat radiation device of diesel of the present utility model after cooling fluid enters upper tank from water inlet, at first impacts on the water distribution baffle plate in the course of the work, and spray can upwards not splash, and is no longer overflowed by passage and causes non-evaporation loss; Cooling water is descending along water distribution baffle plate both sides to be covered with whole upper tank, and water distribution is even, descendingly afterwards can contact heat radiation with all fin by behind the fin of radiator, and radiating efficiency is high.The utlity model has advantage rational in infrastructure, that cooling water loss is few, radiating efficiency is high.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 be among Fig. 1 A-A to cutaway view;
Fig. 3 be among Fig. 1 B-B to half sectional view.
Among the figure: the 1-upper tank; The 11-water inlet; The 2-lower header; The 21-delivery port; The 3-radiator; The 4-water injection pipe; The 41-filler cover; The 42-passage; 5-water distribution baffle plate.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only by the mode of explanation some example embodiment of the present utility model has been described.Undoubtedly, those of ordinary skill in the art can recognize, in the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used for the protection domain of restriction claim.
Such as Fig. 1, Fig. 2 and shown in Figure 3, heat radiation device of diesel, comprise upper tank 1 and lower header 2, be communicated with radiator 3 between described upper tank 1 and the described lower header 2, the sidewall of described upper tank 1 is provided with water inlet 11, and described lower header 2 is provided with delivery port 21, described upper tank 1 top is provided with water injection pipe 4, described water injection pipe 4 is provided with filler cover 41, and the sidepiece of described water injection pipe 4 is provided with passage 42, is positioned at described water inlet 11 places in the described upper tank 1 and is provided with water distribution baffle plate 5.
