Description
Technical field
The utility model relates to a kind of High-Power PTC liquid heaters, are highly suitable to be applied for installation space or environment temperature
Spend limited automobile liquid heating art.
Background technique
Low temperature flames of anger when being worked due to PTC itself, the advantage of safety, service life length, has been widely used in instant heating type liquid
Such as Chinese utility model patent Authorization Notice No. CN 2606296Y U title in heater are as follows: the instant heating type liquid of High-Power PTC
The utility model patent of heater, there are pyrotoxin thermal conductive surfaces sufficiently to contact with liquid for the prior art, thus heating efficiency
The problems such as reducing, also making entire heater external temperature high.External temperature is high, and especially new energy vehicle liquid heater will be with electricity
It controls plate and carries out integrated installation, in order to reduce small product size, this makes the heatproof of automatically controlled making sheet require to greatly improve, and cost increases
Add, safety reduces.
Summary of the invention
Goal of the invention: it is high that the purpose of this utility model is to provide a kind of heating efficiencies, and structure is simple, low in cost, energy
Reduce the technical solution of heater peripheral temperature.
Technical solution: in order to achieve the goal above, the technical solution used are as follows: a kind of high-power PTC liquid heater,
It is characterized in that；Including shell, partition, inner cavity, cover board, PTC heat block, the shell is hollow structure, and shell passes through interior setting
Multiple tracks partition connect with the inner cavity, form multiple flow channel for liquids chambers, the shell both ends are respectively provided with opposite with shell
Cover board, the partition offer the diversion trench that can be sequentially communicated adjacent liquid flow passage chamber, and the inner cavity is hollow structure, institute
PTC heat block is stated to be set in the hollow structure of inner cavity.
Liquid flow through-hole is provided on the cover board.
The position of inner cavity is corresponded on the cover board, and offer can be by the hole PTC of PTC heat block.
As an improvement, the inner cavity can be multiple, in order to high-power when a small amount of increase volume to do more.
As an improvement, protrusion is arranged in the inner cavity outer surface, its purpose is to increase turbulent water.
The shell partition plates inner cavity is integrated extrusion molding, facilitates processing and batch production.
The shell and cover board carries out welded seal by soldering, and flow channel for liquids chamber and cover board form each envelope after welding
Liquid between each chamber is successively gone here and there by the diversion trench opened up and is connected by closed chamber room.
Shell and inner cavity are designed as rectangular configuration, contact surface can be allowed to become much larger in this way, are conducive to heat exchange.
The invention main points of the utility model are, by opening up diversion trench on cover board and partition, liquid can be made followed by interior
The upper of chamber outer surface, each face of left, down, right, make ptc heater more fully be exchanged heat with liquid.It is an advantage of the invention that portion
Part is few, and structure is simple, and heat exchange efficiency is high, feature at low cost.
Detailed description of the invention:
Decomposition view Fig. 1 of the invention
Fig. 2 another embodiment of the present invention figure

Specific embodiment:
The utility model embodiment is illustrated with reference to the accompanying drawing:
A kind of high-power PTC liquid heater, including shell (1), partition (13), inner cavity (14), cover board (2), PTC heating
Block (3), the shell (1) are hollow structure, and shell (1) is connected by the multiple tracks partition (13) and the inner cavity (14) of interior setting
It connects, forms multiple flow channel for liquids chambers (17), shell (1) both ends are respectively provided with and shell (1) opposite cover board (2), and both ends are set
Partition is separated flow channel for liquids chamber (17) and forms independent closed cavity one by one, the partition by the cover board (2) set
(13) offering can make each independent closed cavity successively go here and there the diversion trench (12) that adjacent liquid flow passage chamber (17) are connected to
Connection gets up, and forms the bending of multiple tracks runner, liquid can be followed by upper, left, each face of lower right of inner cavity (14), the cover board (2)
On be provided with liquid flow through-hole (21), liquid is flowed in flow channel for liquids chamber (17) by a liquid flow through-hole (21), and is passed through
Each bending can be flowed out from another liquid flow through-hole (21), and the inner cavity (14) is hollow structure, the PTC heat block (3)
It is set in the hollow structure of inner cavity (14).The PTC heat block (3) being arranged in inner cavity (14) generates heat after being powered, heat conduction stream
Liquid through inner cavity outer surface plays heating liquid purpose.
The position of inner cavity (14) is corresponded on the cover board (2), and offer can be by the hole PTC (22) of PTC heat block (3).
In another embodiment, above-mentioned method can be passed through to be multiple to improve inner cavity described in product power (14)
The outer surface of each inner cavity (14) can be flowed liquid through.
Raised (15,16) are arranged in inner cavity (14) outer surface.Raised (15,16) primarily function is to increase to connect to add
Liquid perturbation improves heat exchanger effectiveness.
The shell (1), partition (13), inner cavity (14) are integrated extrusion molding, greatly reduce product cost, more hold
Easily realize scale.In order to solve the problems, such as that both ends seal, the shell (1) weld by soldering close with cover board (2)
Envelope.The shell (1) and inner cavity (14) is designed as nearly rectangular configuration in this way and the contact area of PTC water flow can be improved.
