Abstract

Provided is a coolant heater, and more particularly, is a coolant heater capable of minimizing a mounting space and weight by integrating the coolant heater and a water pump with each other and improving a cooling effect of the coolant heater and a controller for controlling a coolant transporter.

First claim

What is claimed is:

1. A coolant heater comprising:
a heater case including a first heater case including a second space portion, and a second heater case which is coupled to the first heater case, and having a first space portion formed in the heater case by the coupling between the first heater case and the second heater case;
a heating means insertedly coupled to the second space portion;
a heater cover coupled to an outer surface of the second space portion so that the heating means is accommodated in the second space portion;
a coolant transporter coupled and fixed into the first space portion positioned at a region which is adjacent to the second space portion in an inner side of the first heater case and transporting the coolant by pressure;
a coolant transporter controller disposed on a surface of the coolant transporter of a side on which the second heater case is positioned, and controlling the coolant transporter; and
a heater controller disposed on an inner side surface forming the second space portion of the first heater case and controlling the heating means, in the first space portion.

2. The coolant heater of claim 1 , wherein in the coolant heater, an inlet pipe into which the coolant flows is formed at the first heater case,
an outer pipe through which the coolant is discharged is formed at the heater cover, and
a communication hole is formed to penetrate through a certain region of the surface forming the second space portion in the first heater case.

3. The coolant heater of claim 2 , wherein in the coolant heater, the input pipe is formed in a lower side of a region at which the first space portion of the heater case is positioned, and
the outlet pipe is formed in an upper side region of the heater cover.

4. The coolant heater of claim 3 , wherein in the coolant heater, the coolant flows into the first space portion through the inlet pipe, passes through the communication hole at constant flow velocity by an operation of the coolant transporter to be moved to the second space portion, and passes through the heating means from a lower side direction to an upper side direction and is then discharged to the outlet pipe.

5. The coolant heater of claim 1 , wherein the heating means includes a first header and a second header which are coupled to an upper surface and a lower surface in a height direction.

6. The coolant heater of claim 5 , wherein in the coolant heater, a header insertion groove is formed in an inner circumference surface of the second space portion so that the first header and the second header are insertedly fixed to the second space portion in a horizontal direction.

7. The coolant heater of claim 1 , wherein in the coolant heater, the second heater case is formed of a metal material, and
electric elements of the coolant transporter controller are in surface contact with the second heater case.

8. The coolant heater of claim 7 , wherein the second heater case corresponds to the electric elements of the coolant transporter controller protruding in the width direction.

9. The coolant heater of claim 8 , wherein in the coolant heater, an insulating material which transfers heat and is insulated is applied onto the surface that the coolant transporter controller and the second heater case are in surface contact with each other.

10. The coolant heater of claim 1 , wherein the first heater case includes a coolant flowing portion formed by externally protruding a region of the first space portion to which the coolant transporter is fixed.

11. The coolant heater of claim 10 , wherein the coolant heater includes a flange portion protruding from an outer circumference surface of an end portion of the first heater case side of the coolant transporter, and a coolant transporter cover which is inserted into the outer circumference surface of the coolant transporter and is coupled to the flange portion, and
the coolant transporter cover and the flange portion are fixed to an inner side edge surface of the coolant flowing portion.

12. The coolant heater of claim 11 , wherein the coolant heater further includes a sealing member between the flange portion and the inner side edge surface of the coolant flowing portion.

13. The coolant heater of claim 1 , wherein in the coolant heater, the first heater case is formed of a metal material, and
an electric element of the heater controller is in surface contact with an inner side surface forming the second space portion in the first heater case.
