The present invention relates to a coolant heater comprising: a heating element for heating coolant; a first housing for accommodating the heating element; a cover plate for sealing the first housing in which the heating element is accommodated; a temperature fuse provided in an external space formed by coupling the first housing and the cover plate, and disposed to be adjacent to the cover plate; and a second housing for pressing the temperature fuse so as to pressurize the same toward the cover plate, wherein overheat sensing responsiveness of the heating element is improved such that the overheat of the heating element can be prevented, and failure factors in a part in which the temperature fuse is coupled are reduced such that a durability is improved.

Coolant heater

The present invention relates to a coolant heater. The purpose of the present invention, a coolant heater which effectively heats coolant of a vehicle by means of a heating unit, is to provide a coolant heater having improved sensitivity and responsiveness to over-heating and assured stability by utilizing a temperature fuse to prevent over-heating. Another purpose of the present invention is to provide a coolant heater having enhanced durability of the temperature fuse coupling part by improving the structure by which the temperature fuse is fixed.

The present invention relates to a process for preparation of aripiprazole crystal form II by recrystallizing aripiprazole in a mixture of acetone and 1-methoxy-2-propanol or a single solvent of 1-methoxy-2-propanol. The simple process according to the present invention can produce aripiprazole crystal form II with high purity and high yield in a mass scale.
