Description

TECHNICAL AREA The present disclosure relates to a control system combined with a vehicle heat exchanger and a thermal management system that uses it. BACKGROUND An electric vehicle is equipped with an air conditioning system that includes a compressor, a condenser and an evaporator for cooling and heating the vehicle interior, as well as a thermal management system for cooling batteries, motors and power electronic components (PE) and for recovering waste heat. The air conditioning system has various heat exchangers, such as an evaporator core and a heater core, to implement a heating mode, a heating/dehumidifying mode, and a cooling mode, and the thermal management system also has various heat exchangers, such as a cooler and a heater (e.g., a PTC heater (Positive Temperature Coefficient), hereinafter referred to as PTC) and a battery heater), to implement a battery heating mode, an engine and battery cooling mode, and the like. To solve problems arising from the increased number of parts and the increased costs caused by using multiple heat exchangers in existing air conditioning and thermal management systems, a method is being sought to remove or modify some heat exchangers (e.g., the PTC heater or the battery heater) to reduce the number of parts and the cost. The information disclosed in this background section is provided solely for a better understanding of the background of the present disclosure and may therefore contain information that is not part of the prior art, which is already publicly known, available or in use. BRIEF EXPLANATION The present disclosure relates to a control system combined with a vehicle heat exchanger or a control system combined with a heat exchanger in a vehicle and a thermal management system that uses this system, and in particular a control system combined with a vehicle heat exchanger that is capable of using the heat generated by a sham operation of a control device for heating and/or increasing the battery temperature, as well as a thermal management system that uses this system. One embodiment of the present disclosure can solve the problems described above that occur in the prior art, and one embodiment of the present disclosure can include a control device combined with a vehicle heat exchanger, comprising a control device that performs a sham operation and a heat exchanger plate with a coolant path that is mounted in the control device and is capable of performing a heat exchange between the heat generated by the sham operation of the control device and a coolant that passes through the coolant path of the heat exchanger plate in order to use the coolant after the heat exchange, for example, for heating and/or increasing the battery temperature, and provide a thermal management system that uses this. For example, one embodiment of the present disclosure may provide a control device combined with a vehicle heat exchanger, comprising a control device configured to perform vehicle control operation and sham operation or idle operation (hereinafter referred to as sham operation), and a heat exchanger plate formed with a coolant path therein and attached to a surface (e.g., side) of the control device in which heat exchange can take place between the heat generated by the sham operation of the control device and a coolant flowing through the coolant path of the heat exchanger plate. For example, in one embodiment of the present disclosure, a control device may be provided to have a printed circuit board or circuit board (hereinafter referred to as: circuit board) and a plurality of processors and memories mounted on the printed circuit board to perform the vehicle control operation and the sham operation for heat generation. For example, in one embodiment of the present disclosure, a control device may further comprise a data input unit which replicates and amplifies a vehicle control input signal to generate a dummy signal and inputs the generated dummy signal into each processor. For example, in one embodiment of the present disclosure, a processor may be configured to repeatedly perform a sham operation for heat generation based on the sham signal input via the data input unit and not to output a repetition or resumption operation signal (e.g., a signal that would repeat or resume vehicle operation). For example, in one embodiment of the present disclosure, a heat sink or heat sink (hereinafter referred to as heat sink) can be attached to one side of the control device, which directs the heat generated by the sham operation to the coolant path of the heat exchanger plate. For example, in one embodiment of the present disclosure, at least two subdivisions (e.g. partitions) whose length is less than the width of the heat exchanger plate can be formed in a zigzag shape in the heat exchanger plate, maintaining a defined, predetermined or selected distance, so that the coolant path from a coolant inlet to a coolant outlet is S-shaped.
