Abstract
The utility model relates to a PTC heating device for heating liquid, which belongs to a PTC liquid heater and comprises a PTC heater and a liquid pipeline which is connected with the lower surface of the PTC heater. The utility model is characterized in that the PTC heater is in a plate block shape, the liquid inlet end of the liquid pipeline is connected with a liquid container, and the liquid outlet end of the liquid pipeline is connected with a liquid outlet pipe; the upper surface of the PTC heater in the plate block shape is provided with a heat conducting plate, and the inner wall of the liquid pipeline is provided with an arc shape protrusion which is parallel to the axial direction of the pipeline. The utility model has simple structure and simple and convenient processing, and can carry out forced mixing to the water flow from the lamellar flow to the turbulent flow, which increases the heat exchange process of the water flow and makes fast thermal response and rapid temperature rise; the utility model can realize the effect of heat insulation when heating; the dielectric strength is high, thus the utility model is safe and reliable and is insusceptible to the over-temperature dry combustion, and the service life is long.
Description
Technical field:
The utility model relates to a kind of PTC heater that is used for the liquid heating, and it belongs to a kind of liquid heater, particularly a kind of PTC liquid heater.
Background technology:
The existing disclosed electric heater technology that is used for the liquid heating has two big classes, and a class is to utilize the electrothermal wire heating, and this electric heater can not dry combustion method, and dangerous, the life-span lacks; Another kind of is as heater members with the PTC element, as No. the 942140010.9th, Chinese patent, denomination of invention is: No. the 97226994.0th, " tubular type fast electric heating interchanger ", Chinese patent, denomination of invention is: " PTC liquid electric heater ", though in these technical schemes, all utilized the PTC element, because its structural characteristics, be connected complicated between heater and the liquid container, difficulty of processing is big, and power control is inaccurate, and cost is higher.
Summary of the invention:
It is a kind of simple in structure that the purpose of this utility model is to provide, can insulation in the time of thermal efficiency height, heating, good insulation preformance, the PTC heater that is used for the liquid heating safe in utilization.
The purpose of this utility model is achieved in that
A kind of PTC heater that is used for the liquid heating, it comprises the PTC heater, is connected the fluid pipeline of PTC heater lower surface, described PTC heater is plate-like; Liquid feeding end place at described fluid pipeline is connected with a liquid container, is connected with a drain pipe at the outlet end place of described fluid pipeline.
Upper surface at described plate-like PTC heater is provided with a heat-conducting plate.
Described heat-conducting plate is a metallic plate.
On the inwall of described fluid pipeline, be provided with the arcuation projection parallel with pipeline axial.
Two sides at the outer wall of described plate-like PTC heater all are provided with v shape groove.
Two terminations at described PTC heater are provided with fluid sealant.
Liquid outlet at described liquid container is provided with a Liquid valve.
The utility model is simple in structure, handling ease, convenience; Can force stirring to form turbulent flow by laminar flow in current, increase the heat exchange process of current, thermal response be fast, heats up rapidly; Can realize heat preservation effect in the time of heating; The dielectric strength height, safe and reliable; Be not afraid of overheated dry combustion method, long service life.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model
Accompanying drawing 3 is PTC heater of the present utility model and fluid pipeline structural representation
Accompanying drawing 4 is the structural representation of user mode of the present utility model
The specific embodiment:
Be embodiment of the present utility model with accompanying drawing 1,2,3 below, the utility model be further detailed:
As shown in accompanying drawing 3, of the present utility model being constructed as follows that present embodiment is given: it comprises PTC heater 4, is connected the fluid pipeline 3 of PTC heater lower surface, and described PTC heater 4 is plate-like; In order to increase the heat-conducting area of described PTC heater 4 upper surfaces, reach good heat insulation effect, be provided with a heat-conducting plate 2 at described PTC heater 4 upper surfaces, heat-conducting plate 2 is chosen as metallic plate in the present embodiment.PTC heater 4 in the utility model is a prior art, and it comprises insulating materials, is wrapped in PTC heater element and outermost battery lead plate in the insulating materials.Of the present utility model safe in utilization in order to guarantee, product good insulation performance effect is provided with fluid sealant 6 in two terminations of described PTC heater 4.Liquid feeding end 31 places at described fluid pipeline 3 are connected with a liquid container 1, are connected with a drain pipe 5 at outlet end 32 places of described fluid pipeline 3.Be provided with the arcuation projection 7 parallel with pipeline axial on the inwall of described fluid pipeline 3, the water that can prevent from like this to enter in the fluid pipeline 3 forms laminar flow, influences the heat exchange of liquid, thereby improves heat exchanger effectiveness.In order to overcome the difficulty that the PTC aluminum pipe is difficult to suppress in the prior art, all be provided with v shape groove 8 in two sides of the outer wall of described plate-like PTC heater 4.
When needs heat certain liquid, as with Hot Coffee the time, at first coffee pot 10 is placed on the heat-conducting plate 2 of PTC heater 4 upper surfaces, adorn water in described liquid container 1, and open the Liquid valve 11 of the liquid outlet of liquid container 1, water will be from the liquid feeding end 31 of liquid outlet influent pipeline 3, enter fluid pipeline 3, by heating, the outlet end 32 from fluid pipeline 3 flows into drain pipe 5 again, just can put into coffee pot 10 through the water of heating like this.Because coffee pot is placed on the heat-conducting plate 2, therefore can also reach the purpose of insulation.
