Abstract
The utility model discloses a multi-layer PTC water heater. The multi-layer PTC water heater comprises a PTC heater metal housing. Two or more PTC heating units are installed inside the PTC heater metal housing, a layer of metal thermally-conductive layer is arranged between any two PTC heating units, and a notch is formed in the middle portion of each metal thermally-conductive layer. The multi-layer PTC water heater is electrically connected with an external power supply through a power line. The multi-layer PTC water heater is used to heat water or other liquid contained in a container (or a pipeline) through the external metal structure and the interlayer metal thermally-conductive layers. According to the utility model, advantages of large heating power density per unit surface, fast heating speed, and easy metal structure fabrication are realized.
Description
Technical field
The utility model relates to a kind of multiple field PTC water heater, more particularly, is that a kind of per surface power density is large, and firing rate is fast, the electric heating PTC water heating elements of easily making.
Technical background
Individual layer PTC water heating elements in the past is to adopt the in-built one deck PTC of metal shell heating unit, and the PTC heating unit is connected with external power supply by power line.When needing to use, individual layer PTC water heating elements is put into the water that will heat, connected power supply and heat, there is following defective in the PTC water heating elements of this structure: firing rate is slow, the heating power of per surface is low, can not satisfy the requirement of high-power heating.
And patent ZL201020135626.0 Combined PTC liquid heater is that a kind of surface power density is large, the PTC liquid heater that firing rate is fast, but the metal structure of this PTC liquid heater is difficult for processing.
The utility model content
The purpose of this utility model is to overcome defects of the prior art, provides that a kind of easy processing, firing rate are fast, the much higher laminar PTC of the heating power water heater of per surface.
For achieving the above object, the technical scheme that the utility model provides is as follows: a kind of multiple field PTC water heater is provided, the multiple field PTC water heater that contains two or more PTC heating units, comprise the ptc heater metal shell, be equiped with two or more PTC heating units in described ptc heater metal shell, this PTC heating unit is electrically connected with external power supply by power line.
Be interval with and the integrated metal guide thermosphere of ptc heater metal shell in the described multiple field PTC water heater body, metal guide thermosphere middle part has breach, the metal guide thermosphere separates two adjacent PTC heating units, and the heat of conduction PTC heating unit generation is transmitted in the water to the outside of ptc heater metal shell again.
The beneficial effect of multiple field PTC water heater described in the utility model is: the ptc heater metal shell contains multilayer PTC heating unit, can produce larger power, makes ptc heater metal shell surface obtain larger conducted power.The utility model is compared with PTC water heater in the past, in the situation that equal-wattage can be done littlely; In the situation that equal volume can obtain larger heating power.The utility model is compared with the ZL201020135626.0 Combined PTC liquid heater, and metal structure is more easily made.
Below in conjunction with drawings and Examples multiple field PTC water heater described in the utility model is described further.
Description of drawings
Fig. 1 is the front view of multiple field PTC water heater described in the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
Below the example of multiple field PTC water heater described in the utility model, therefore do not limit protection range of the present utility model.
With reference to Fig. 1, Fig. 2, a kind of multiple field PTC water heater is provided, comprise heater metal shell 1, in heater metal shell 1, be equiped with two or more PTC heating units 2; This PTC heating unit 2 is electrically connected with external power supply by power line; Be interval with metal guide thermosphere 3 in the described ptc heater metal shell 1, metal guide thermosphere 3 separates two adjacent PTC heating units 2; Ptc heater metal guide thermosphere 3 middle parts have breach 4, and described PTC heating unit 2 is connected with external power supply by power line 5.
The heat that metal guide thermosphere 3 produces two adjacent PTC heating units 2 is transmitted to the outside of heater metal shell 1, is transmitted in the container that is loaded with other liquid of water again and heats.Described metal guide thermosphere 3 middle parts have breach 4, make with convenient.
Above-described embodiment is the better execution mode of the utility model; but execution mode of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and the principle, substitutes, multilayer, simplification; all should be the substitute mode of equivalence, be included within the protection range of the present utility model.
