Abstract
A kind of oil heater of diesel engine, include housing and heating stick, in described housing, there is fuel gallery, described housing is provided with the filler opening and the oil outlet that communicate with fuel gallery, it is characterized in that described heating stick includes heating pipe, described heating pipe inserts in housing, and described fuel gallery is spirality.Compared with the fuel gallery of the oil heater of equal length in prior art, fuel gallery of the present utility model is longer, diesel oil is more of a specified duration through the required time of fuel gallery like this, the time of heat exchange is also longer, the temperature difference at heater two ends is larger, compared with the heater of equal length, heating effect of the present utility model is better, ensures that oil outlet temperature reaches necessary requirement.
Description
Technical field
The utility model relates to a kind of improvement invention of oil heater, particularly be a kind of oil heater used for diesel engine.
Background technique
0
#diesel oil needs heating below at 4 DEG C, makes fuel oil temperature reach the requirement under motor nominal situation.Conventional heating equipment has oil pipe Resistant heating, the heating of filter core electric heating coil, hollow bolt heating, plate heating filter block etc. at present, and above-mentioned heating equipment exists the problem that heating effect is poor, heat energy loss is large and safety coefficient is low.
Summary of the invention
In view of the technical problem that background technique exists, it is good that technical problem to be solved in the utility model is to provide a kind of heat exchange effect, the oil heater of the diesel engine that the efficiency of heating surface is high.
In order to solve the problems of the technologies described above, the utility model is that the following technological scheme adopting realizes: the oil heater of this kind of diesel engine, include housing and heating stick, in described housing, there is fuel gallery, described housing is provided with the filler opening and the oil outlet that communicate with fuel gallery, it is characterized in that described heating stick includes heating pipe, described heating pipe inserts in housing, and described fuel gallery is spirality.
The winding of described fuel gallery is outside heating pipe.
Described heating pipe is arranged on outside spirality fuel gallery.
Described heating stick also includes bolt, and described heating pipe and bolt welding form, and described bolt is threaded with housing.
In described heating pipe, be provided with heating element, described heating element is PTC heater element or resistance wire heater element, and the power line of described heating element is placed in outside housing.
Fuel gallery of the present utility model adopts spirality, compared with the fuel gallery of the oil heater of equal length in prior art, fuel gallery of the present utility model is longer, diesel oil is more of a specified duration through the required time of fuel gallery like this, the time of heat exchange is also longer, and the temperature difference at heater two ends is larger, compared with the heater of equal length, heating effect of the present utility model is better, ensures that oil outlet temperature reaches necessary requirement; The position of described heating pipe setting can be divided into two kinds, and a kind of the inside that makes to be arranged on spirality channel is another kind of be arranged on the outside at spirality channel.While being arranged on the inside of spirality channel, heating pipe adopts welding manner to be connected with bolt, connect interwoveness, therefore heating pipe is to seal shape completely in housing, and diesel oil can not enter in heating pipe, also just can not contact with the heater element such as PTC or resistance wire, thereby avoid heater element impaired, lost efficacy, and the power line of heating element is placed in outside housing, avoids power line to contact with diesel oil, stop, because both positive and negative polarity short circuit produces the safety problem that spark causes, greatly to improve safety coefficient.
Brief description of the drawings
Further describe working principle of the present utility model and details thereof below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment one structural representation.
Fig. 2 is left view in Fig. 1.
Fig. 3 is the utility model embodiment two structural representation.
Fig. 4 is left view in Fig. 3.
Embodiment
By reference to the accompanying drawings, the oil heater of this kind of diesel engine, include housing 1,1 ' and heating stick, in described housing, there is fuel gallery 2,2 ', described fuel gallery is spirality, described housing is provided with the filler opening A and the oil outlet B that communicate with fuel gallery, and described heating stick includes heating pipe 3,3 '.In embodiment one, heating stick also includes bolt 4, described heating pipe and bolt welding form, described heating pipe inserts in housing, described bolt is threaded with housing, heating pipe at housing in complete sealing state, avoid diesel oil to enter in heating pipe, and heating stick can dismantle flexibly, convenient; In described heating pipe, be provided with heating element, described heating element is PTC heater element, also can adopt resistance wire heater element, and the power line of described PTC heater element 5,5 ' is introduced outward by housing, so stop, because both positive and negative polarity short circuit produces the safety problem that spark causes, to improve Security.
Embodiment one, and with reference to accompanying drawing 1, the fuel gallery winding of described spirality is in the outside of heating pipe;
Embodiment two, and with reference to accompanying drawing 3, described heating pipe is arranged on the outside of spirality fuel gallery.
Low temperature diesel oil is entered in fuel gallery by filler opening, heating element heating, transfer heat to the diesel oil in fuel gallery, diesel oil is rapidly heated, because fuel gallery is spirality, and winding is outside heating pipe, diesel oil mobile distance and mobile time in heater are so increased, also just extended the time of heating, therefore adopted the heater of equal length, the utility model is more of a specified duration to the time of diesel heating, thereby the thermal energy that diesel oil obtains is more, temperature is also higher, thereby ensures that diesel oil is from oil outlet out time, and it is temperature required that temperature has reached.
The utility model compared with prior art heating effect is better, uses safer.
