Abstract
The utility model relates to a PTC liquid heater. The utility model is characterized in that: the PTC liquid heater comprises a main body formed from an electrothermal material; the inside of the main body is provided with a longitudinal passage for a liquid to flow through; the inside of the main body is also provided with a longitudinal through hole arranged in parallel with the longitudinal passage; and the inside of the longitudinal through hole is provided with a PTC heating element. Compared with the prior art, the utility model has the advantages that: by directly moulding the longitudinal passage for the liquid to flow through and the longitudinal through hole which is used for the PTC heating element to be arranged in and is arranged in parallel with the longitudinal passage in the electrothermal main body, the heat exchanger effectiveness between the PTC heating element and a heat exchange surface of the longitudinal passage for the liquid to flow through is increased; and the PTC liquid heater has simple structure and easy processing and manufacturing.
Description
Technical field
The utility model relates to a kind of PTC liquid heater.
Background technology
Along with the continuous development of heater technology, various liquid heaters arise at the historic moment, and existing P TC liquid heater mainly contains two kinds of structures, and a kind of is that the PTC element is fixed on metal tube one surface after insulation, to realize the heating to liquid; Another kind is that the PTC element is embedded after insulating on metal tube one surface that has groove, to realize the heating to liquid.And there is following shortcoming in the PTC liquid heater of these two kinds of structures: at first, can't combine closely between PTC electric heating member and the metal tube, thereby influence giving full play to of PTC element heat energy; Secondly, because of the thermal expansion phenomenon that heater produces when working, in use reach to be prone to produce between PTC electric heating member and the metal tube and become flexible phenomenon and cause the heater power decay.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, PTC liquid heater that the thermal efficiency is high at above-mentioned prior art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this PTC liquid heater, it is characterized in that: comprise a body of making by thermo electric material and type aluminium, this body has a through-flow for liquid vertical passage, also be provided with the longitudinal hole that be arranged in parallel with described vertical passage in the described body, the PTC heater element is set in the described longitudinal hole.
Described longitudinal hole is provided with two, is symmetricly set on the both sides of described vertical passage respectively.
Described body integral body is column structure, and described PTC heater element compresses it after being arranged in the described longitudinal hole, and the fluid sealant sealing is adopted in two ends.
As improvement, the utility model also comprises a shell, and described body is arranged in the described shell, and has inlet opening and apopore that two ends for vertical passage on the described body pass on the described shell.
Have the wire guide that lead passes of drawing on the described shell for described PTC heater element.
Have installing hole on the bottom surface of described shell.
Compared with prior art, advantage of the present utility model is: by through-flow for liquid vertical passage of straight forming in heater body and the longitudinal hole that be arranged in parallel with vertical passage placed for the PTC heater element, make that heat exchanger effectiveness increases between the heat-exchange surface of the vertical passage of PTC heater element and liquid communication in the utility model, simple in structure, be easy to processing.
